Can I upgrade the graphics processor of my Dell Inspiron 9000 laptop/notebook computer?
Question
I have a Dell Inspiron 9000 laptop PC that has an integrated Intel 915GM graphics processor. My question is, can I upgrade the graphics processor to a more powerful one? I understand from reading that I've done on the subject that, if it is possible with this model, I would have to disassemble the laptop to remove the graphics chip and then install the new chip, or add a graphics card if the laptop has a slot for one.
Answer
The current position in August 2007 is that you can only upgrade the graphics capability of a laptop/notebook computer under very limited circumstances. The graphics chip has to be on a separate, replacable graphics card, not integrated into the motherboard.
Most laptop computers use an integrated graphics controller that uses system RAM memory, but some have the provision for a graphics card that has its own dedicated video memory. Many recent integrated graphics controllers used in laptops use PCI Express technology, which means that the signals sent from the processor to the graphics processor are compatible with PCI Express standards. However that doesn't necessarily mean that they also have a PCI Express slot.
Both desktop and laptop PC's can have integrated graphics (the graphics chip is integrated into the motherboard) and also provide a slot for a video/graphics card.
Dell graphics cards are proprietory, which means that they can usually only be upgraded if Dell supplies a choice of graphics options for that particular model. When you buy a Dell PC online you can often choose from a range of graphics cards. Note, however, that Dell can use several makes of LCD screens on the same model and high-end graphics cards may only work with certain makes of LCD screens. The following webpage list the graphics options of each Dell laptop: http://www.bay-wolf.com/videoupgrade.htm.
You should also note that the laptop's BIOS has to be compatible with the new graphics card. A particular laptop could use an MXM-compatible or AXIOM-compatible card (more information on that compatibility is provided below), but its BIOS could be hard-coded with the configuration details of the card that was originally installed. If that is the case, a BIOS update that supplies the configuration details of the new card would have to be installed.
In most cases when you purchase a laptop computer, you cannot upgrade the graphics. Fortunately, you are in luck, because the Dell Inspiron 9000 has integrated Intel 915GM graphics and can also be fitted with an ATI Radeon graphics card. Having first checked the position with Dell, you should be able to purchase one from Dell and fit it yourself, or, if you don't trust yourself to do the job, send the laptop in to Dell for the fitting. Remember that even opening a laptop computer can be difficult. If you don't know exactly how to do it, you can break plastic tabs, etc.
Desktop PCs have just one PCI Express standard for graphics card slots, but there are two 'standards' for laptop/notebook computers. nVidia calls its version MXM, which stands for Mobile PCI Express Module, and ATI calls its version AXIOM. Apparently, each version has several types with different size and heat dissipation requirements. Some laptop manufacturers have customised the BIOS in their systems so that only the MXM cards that they supply can be used. Some laptop manufacturers, such as Toshiba, have their own non-standard slots for graphics processors.
Unfortunately, most of the laptop computer manufacturers will only guarantee compatibility with their own graphics cards. Moreover, most of them don't even provide the information that their laptops have an MXM or an AXIOM slot.
Here is the information I have found on MXM:
MXM -
"As early as 2004, NVIDIA introduced a standard for mobile modular graphics cards. MXM, which stands for Mobile PCI EXpress Module, aims to allow notebook manufacturers to bring their product faster to market and to design a single platform which suits a manifold of graphics modules. On top of that, the standard is open, which means that an ATI MXM card is possible, allowing manufacturers an even greater flexibility. Based on 16 lanes of PCI-Express (the same as its desktop brethren), MXM is here to stay for the long run. Now that most new laptops are based on new chipsets, which feature PCI-Express technology, more and more MXM powered laptops are arriving on the market. MXM's history looks bright indeed!" -
"If your laptop is not in the list of MXM powered parts that can be found here, there's still a chance that there's an MXM under the hood. This page contains tips and tricks. But before you proceed, you should understand that opening up your laptop will void your warranty. Furthermore, it is quite a bit more complex then opening up a desktop PC. Laptops are not really made to be taken apart, especially not by inexperienced hands. If you don't know exactly what you are doing, chances are you're going to break some tabs, damage the interior of you're going to find yourself being generally unable to assemble all the parts together again. So, leave your laptop alone if you're not exactly sure what you're doing!" -

Can I upgrade my notebook computer's processor?
Question
My Mitac Iqon 8089P notebook computer is running an Intel Celeron M 1.5GHz processor and 256MB of RAM memory. Some time in the future I would like to be able to add additional RAM and upgrade the processor. I know that the notebook has a spare memory slot, because it says so in its user manual, but I can you tell me if I can change the processor to an Intel Pentium M model?
Answer
Adding a second 256MB module of RAM would provide a significant boost in performance because the recommended minimum amount to run Windows XP on is 256MB, and some of that is used by the graphics engine, so it is not available for Windows to use. (Windows XP runs much more comfortably on 512MB, with 1GB (1024MB) regarded as being its 'sweet spot'.) The amount of RAM reserved for use by the graphics engine can be between 32MB and 128MB. Your user manual should be able to tell you how to set the amount of system RAM used by the graphics engine. Therefore, Windows XP is running on less than 256MB. You can make use of the UK and US Crucial Memory Selectors at the top of the page to find the right RAM for that notebook, which is guaranteed by Crucial to work or your money back.
However, it is not a good idea to upgrade the processor. For a start, you'll probably have to pay a suitable PC technician that specialises in notebook PCs to change it, because the processor in a notebook is usually hidden within the body of the computer's components, which are installed like the parts in a mechanical watch. You have to know how to remove them and how they go back together. The components are delicate, and, if you aren't experienced, you can damage them so that they no longer function. Upgrading a desktop PC is relatively easy because of the modular nature of the components, but the highly integrated nature of the components in a notebook makes it very difficult to work with them.
Moreover, the manufacturers of notebooks don't expect that the processor will be changed, so the computer's BIOS setup program might not support a different processor. But even if it does, or you can download a BIOS update that supports a faster or superior processor from the PC manufacturer's site in order to reflash the BIOS, the computer's cooling system, designed for the installed processor, might not be able to cope with the upgrade and overheat, which can cause the components permanent or even fatal damage, so do yourself a favour and forget about upgrading the processor.
Is it possible to buy a small set of stereo speakers for use with my notebook computer that provide good sound?
Question
I use my IBM R50e notebook computer to play DVDs on the road. The picture quality is good, but the quality of the sound delivered by the single speaker is very poor. Is it possible to buy a decent set of speakers that can be powered from the computer? I don't need surround sound, just one or two speakers that provide a decent level of volume.
Answer
It is possible to buy a set of speakers designed for mobile use. They can usually be connected and powered via a USB connection, internal batteries, or an external mains adapter. The Philips DGX320 set of speakers draw power through a USB connection. However, the On Tour speakers made by JBL, priced at around £60 in January 2006, provide superb sound quality. The set of two speakers are housed in a single unit that has a sliding cover that protects them. It can be powered by batteries or from a mains adapter. You can find information and vendors on these by entering the following search terms, as is, in the Google search box at the top of this page, with its Web radio button enabled: "philips dgx320" and jbl + on tour.
What do I need in a laptop/notebook computer to be able to have a wireless connection to the Internet?
Question
I want to buy a laptop computer that allows me to be able to connect to the web wirelessly or to which a wireless connection can be added. But I am confused by what I have read on the subject. What I've 'understood' so far is that some laptops come with a specification called HSDPA, a faster version of 3G that 3G mobile phones use to access the web. I take it that I don't have to add anything to a laptop with HSDPA. I know that you can insert a data card into a laptop that has the correct slot that provides wireless web access. Is that an HSDPA data card?
I have also noticed from reading the specifications of different laptops that some of them have a PCMCIA adapter card slot, others have an ExpressCard adapter slot, and some laptops have both types of slot. Apparently, the ExpressCard cards are smaller than the PCMCIA cards, so can an ExpressCard adapter fit into the slot for a PCMCIA card, or must you only buy specific cards for specific slots?
Answer
HSDPA stands for High-Speed Downlink Packet Access. It is one of several technologies that are collectively referred to as 3G. Another is called Universal Mobile Telecommunications System (UMTS).
3G - http://en.wikipedia.org/wiki/3G
High-Speed Downlink Packet Access - http://en.wikipedia.org/wiki/HSDPA
Universal Mobile Telecommunications System - http://en.wikipedia.org/wiki/Universal_Mobile_Telecommunications_System
If a particular area is covered by a 3G network, with a 3G mobile phone or a suitably equipped computer, you can access the Internet at broadband speeds. However, you must check the 3G reception in your area, because within a relatively small area, at different points, or at different times of the day, you can have no reception to excellent reception. If the reception is weak, the equipment will probably fall back to using a relatively slow GPRS (General Packet Radio Service)connection, which is about as fast as a dial-up connection.
General Packet Radio Service [GPRS] - http://en.wikipedia.org/wiki/General_Packet_Radio_Service
The mobile phone service provider you intend to use should provide a service on its website that provides reception strengths for 2G and 3G reception on a post/zip-code basis. You enter your post/zip code and a map is delivered showing the reception in that area. In my experience, some areas have a constantly strong 3G reception, while other areas nearby can have variable reception that wavers from strong to weak. There are also areas that don't have any reception, which is why you must check the reception at your post/zip code. T-Mobile's site in the UK provides you with the reception at home and at work.
A 3G data adapter card can be added to almost any notebook that doesn't come with built-in 3G support, but it will make use of an adapter card slot or a USB port.
Most of the HSDPA data cards have an aerial that protrudes from the computer, but some data cards use UMTS, which doesn't use an aerial. An example in the UK is the data card that T-Mobile provides for its Web 'n' Walk service. The data card requires a PCMCIA CardBus card slot in a laptop. Use in a desktop PC using a PCMCIA adapter is not supported because of the variation in reception from even different areas in the same house or building. Another service is provided via a Vodaphone3G Datacard, which also uses a PCMCIA CardBus slot.
Most computers purchased within the last five years have a 32-bit PCMCIA CardBus slot, but new computers often only come with an ExpressCard slot, which is not compatible with the PCMCIA standard. As you said, some laptops have both types of slot. You wouldn't be able to use T-Mobile's or Vodaphone's 3G data cards in a ExpressCard slot.
Laptops that have built-in HSDPA, will just have a slot for a SIM card. You will have to subscribe to a mobile phone provider that will provide you with a SIM card that you could also use in a mobile phone. In fact, you might find that you have to install the SIM card in a mobile phone to get it registered with the network the first time that you use it.
I use my laptop in the office and on the road, but it doesn't support a docking station, so what is the best way to connect it up to many desktop peripheral devices?
Question
I use my laptop PC at my desk and on the road. When I get back to my desk, I have to reconnect the external keyboard, mouse, and DVD writer. The laptop doesn't support a docking station, so can you tell me if there is a simple way to make reconnecting it as easy as possible?
Answer
Almost all of the peripheral devices you can buy today can connect via a computer's USB ports, which all current desktop and laptop/notebook computers provide. If you are using a keyboard or mouse that connects via a parallel or serial port, change them to USB devices. Your external DVD writer must already connect to the laptop via its USB port. Then buy a self-powered USB hub that connects to the mains. You would connect the devices to the hub and then connect the hub to the laptop via its single USB cable. An recommended example is the Trust 7 Port USB2 Powered Hub. Locate information on it and vendors by entering trust 7 port usb2 powered hub, as is, in the Google search box at the top of this page, with its Web radio button selected.
However, if you use an external PC monitor, you will have to connect it as you normally do, because PC monitors can't use a USB connection. Note that you can buy a special stand that you attach a notebook to so that its screen is held at the best viewing angle. An example is the Ergo Station from Port that costs £47.
Is my notebook/laptop computer running too hot?
Question
My new notebook computer feels much hotter than I think it should be on the left side, which is not around the battery. It also smells a bit of burning electronics, which was more noticeable when I first got it, so perhaps it is now "burnt in", so to speak.
These are the temperature results that SpeedFan produced:
HDD = stands for the hard drive temperature, and CPU = stands for the processor's temperature, in degrees Celsius.
At startup, HDD = 22, CPU = 28. After 30 minutes of doing nothing but log in, HDD = 43, CPU = 56. After 10 minutes of a virus scan, HDD = 47, CPU = 67. After about 20 more minutes of the virus scan when it is complete, HDD = 53, CPU = 56. After 40 minutes being idle, HDD = 53, CPU = 58. The machine is only a month old. I'd like to know what the normal operating temperature is for a notebook computer. My desktop PC, which has two case fans that pull air in and push it out, never goes above 45 degrees.
Answer
The most common components in a notebook that produce a lot of heat are the battery, the hard drive, and the processor. Being the key component, the processor is usually the best cooled. From your description, I would say that the hard drive is producing the heat that you feel through the case.
Each manufacturer sets the acceptable maximum temperatures for a PC's or a laptop's components. Usually, hard-drive vendors warn against temperatures over about 50 degrees C, so your readings in the low 50's suggest overheating. The only way to know for sure is to check either the vendor's or the hard drive manufacturer's technical specifications.
You can find out the make and model of the hard drive (or any of the other components) by using a utility such as the Belarc Advisor. It creates an analysis of the hardware and software on a personal computer. Look for it under FREE DOWNLOAD - http://www.belarc.com/. Alternatively, you can examine the hard drive itself, which will be labelled. You can usually access the hard drive in a notebook by opening a covered compartment on the bottom or the side of the case. You may have to remove a couple of screws to get to it, but you almost certainly won't have to take the whole computer apart, because notebook hard drives are one of the few components that can be upgraded, and so access is made a simple matter.
Alternatively, the notebook's manufacturer or the the processor's manufacturer should be able to provide you with the correct operating temperatures. Intel and AMD usually specify maximum temperatures of around 70 degrees C. Therefore, your temperatures are probably close to the maximum, but nevertheless may still be below being dangerously high.
Note that the maximum temperature that a component can run at is not the same as the recommended temperature, which is much lower. Anyhow, with electronic components, the cooler, the better. A component may not fail immediately running at a high temperature, but sustained use at high temperatures will almost certainly shorten the component's lifespan
Using a LapDesk ensures a good flow of air all around the machine.
Targus Notebook Portable LapDesk™ -
http://www.targus.com/us/product_details.asp?sku=PA243U
On a new notebook that is properly cooled, the processor should run at a maximum temperature of about 45 to 47 degrees C when running its most demanding tasks, with the hard drive running at about 35 degrees C.
There is information on Page 2 on overheating in laptops.
Is it advisable to buy an expensive bag for a laptop computer?
Question
I need to to buy a carrier bag for my laptop computer. I want it to look like a normal bag. Should I just buy an ordinary bag, or should I pay a lot for one that is especially designed for a laptop?
Answer
You should buy a bag specially designed for a laptop. Such a bag has padding on the sides and air-filled cushions on the bottom to prevent damage. If you should drop an unprotected laptop, the hard drive, the optical CD/DVD drive, and the screen could be damaged, necessitating costly repairs. Some laptops are themselves specially designed in order to be able to absorb shock and rough use, but even they can be damaged by a serious fall.
Port Designs make a good product. It's Seattle bag that costs around £29 would be a good investment. To locate vendors, enter a search such as "port designs" + seattle (as is) in the Google search box provided at the top of this page, with its Web radio button enabled.
Can a foreign notebook computer with a foreign version of Windows work with English software?
Question
My daughter is living in France with her husband. She doesn't speak much French, but her French husband speaks English fluently. They want to buy a notebook computer, but don't know if a French notebook running the French version of Windows will work with English software. Can a Windows computer be set up so that it works in English for my daughter and in French for her husband?
Answer
French keyboards use the same standard QWERTY layout as UK keyboards. You can change a UK keyboard's layout so that it uses the French layout and regional settings, and vice versa, under Regional and Language Options in the Control Panel in Windows XP, but you have to find out which keys are changed. For example, changing a UK keyboard to a French keyboard will make the colon and @ keys into accent keys, etc. Some notebooks provide replacement keys for different languages. If so, you would change the keyboard in Windows and then change the keys to reflect the change. If you don't have replacement keys, you'll just have to remember where the changes are or put stickers on the keys.
However, you can't change the language that Windows uses for its menus and help files, etc., unless you are using the corporate version of Windows for business use.
Since your daughter and her husband can both speak English, buying a notebook in the UK is probably the best option. You should make sure that it has a European warranty to cover them if it develops a fault that requires repairing.
If the English version of MS Office is being used, you can set its dictionary to the language of the person who is using the notebook. Moreover, Windows XP provides multi-user support. It would allow your daughter to set up a user account (under User Accounts in the Control Panel) that makes use of the British English dictionaries and regional settings, and her husband can set up a user account with the French options.
Alternatively, you can install an English version of Windows XP on a French computer, or run a dual-boot system with both the English and the French versions installed. In a dual-boot system, a boot menu would present itself at startup and allow the user to choose which version to boot.
How can I connect my notebook PC through my mobile phone?
Question
I would like to connect my laptop computer through my mobile phone. Can you advise me on the best way to do that?
Answer
The Vodaphone 3G Data Card allows you to connect to the Internet without a mobile phone.
The Vodafone Mobile Connect 3G/GPRS data card can be used with almost any laptop to provide high-speed Internet services and e-mail access, allowing you to work wherever you are.
Enter vodaphone + 3g + data + card (as is) in the Google search box at the top of this page (with its Web radio button enabled) to located vendors.
No need to use a separate mobile phone and no complicated setup process. Simply install the Vodafone Mobile Connect dashboard software and then insert the data card into your laptop.
Mobile Connect takes advantage of Vodafone's 3G network, offering connection speeds that are up to seven times faster than a 56k PSTN dial-up modem connection. If you find yourself in an area without 3G coverage, it will keep you connected by switching automatically to the well-established GPRS data service. You can also use a wireless LAN enabled laptop to access the Vodafone WLAN service through the dashboard software in any of Vodaphone's partners' hotspot locations. The on-screen Dashboard for Mac (v1.0 or later) or Windows (v3.0 or later) allows you to access internet-based e-mail accounts, browse any webpage, send and receive text messages, chat using instant messages, monitor your usage (for 3G and GRPS), and connect to your company network using a Virtual Private Network (VPN).
There are two options - 250MB of data per month for £30 per month (in May 2006), or unlimited data for £52.88 a month.
If you want to connect via a mobile phone, choose a phone contract that provides GPRS or 3G data access. GPRS is the slower of the two, but offers more coverage.
You should look for a phone that supports Bluetooth, because it is the easiest way of connecting a notebook to a phone. You may have to purchase a Bluetooth adapter for the notebook, such as the USB Bluetooth Adaptor made by My Memory and priced at £9. Making a connection can be tricky, but there is plenty of advice that you could locate by using a suitable search term in the Google search box at the top of this page (with its Web radio button enabled). Try using a term such as: connect + "mobile phone" + bluetooth + adapter (as is).
You can keep any existing phone number if you have to change your service provider. When you disconnect your current phone, ask your provider for your Porting Authorisation Code (PAC). There may be a small charge for the code. Telephone to provide the new service provider with the PAC. It takes between five and seven days to complete the transfer.
Can I buy a cheap replacement for my laptop/notebook computer's power supply?
Problem
The power supply for my laptop computer has died. Its manufacturer wants to charge me nearly £100 for a replacement. I've searched the web for a cheaper alternative replacement without success. Is is possible to buy a cheaper replacement?
Answer
Universal notebook power supplies
All of the notebook computer manufacturers charge a small fortune for replacement power supplies. However, you don't have to buy a replacement made by a particular notebook manufacturer, because you can buy a universal power supply.
Here is an example - Kensington High Power Universal AC Adapter. You could use the Google search box at the top of this page, with its Web radio button enabled, to search for alternative suppliers and reviews. Use a search term such as: notebook universal ac/dc power adapter.
That particular power supply comes with all of the adapters required to connect it to many different types of notebook/laptop computers.
Batteries and Chargers - "Your laptop is indispensable, but have you ever thought about what would happen if you were to lose its power supply or damage the battery? Official replacement parts can be hard to find and even then they can cost hundreds of pounds – so what solution is there? At Laptops Direct we offer a comprehensive and easy to use method to find the right accessory for your laptop at a price that can’t be beaten. It’s called the 'Power Product Configuration Wizard' and as long as you know the brand name of your laptop then you’ll be able to find what you need. There’s no fiddling around with serial numbers or part numbers - just let us know what you have, what you need and we’ll do the rest, even if you didn’t buy your laptop from us in the first place!" - http://www.laptopsdirect.co.uk/Batteries_and_Chargers/cat.asp
As well as being cheaper than power supplies supplied by the notebook manufacturers, you could use such a universal power supply with other notebooks.
If you use a notebook computer at home and at work, using a universal power supply is a good way of providing mains power in both locations without having to carry an adapter with you.
Here is information that is US-specific that I found on a newsgroup:
"While a little more expensive you can buy a "Universal" Notebook AC-to-DC adapter at Radio Shack. I use one for notebook repair where the power brick is missing or defective. The output voltage is selectable and comes with an assortment of plugs. It is important that you orient the +/- terminals correctly. Usually, a notebook will have a label on the bottom that has power information. Also if you have a Batteries+ store in your area they usually have a large choice of AC power units for notebooks. The Radio Shack unit is a lot more expensive than a OEM replacement - running around $90."
Which cables do I need to connect my laptop PC to my LCD TV in order to play high-definition movies using its Blu-ray/HD DVD drive?
Problem
I have a laptop PC that has a Blu-ray/HD DVD optical drive. The computer has both standard analog VGA and digital DVI video output ports. I want to know which cable or cables are required to connect the laptop to my LCD TV in order to be able to watch high-definition movies. The back of the TV has SCART, component, S-video, HDMI and VGA input ports. The laptop has a 3.5mm jack plug audio output.
Answer
You can't use an HDMI high-definition cable that supports both video and sound because the laptop doesn't have an HDMI output port. Since the laptop has both VGA and DVI outputs, there are two ways to connect it to the LCD TV: a VGA cable connected to the laptop's VGA port and the TV's VGA input port and a DVI-to-HDMI cable from the laptop's DVI output to the TV's HDMI input port. Both methods have pros and cons.
Being wholly digital, the DVI option should provide superior image quality to analog VGA, because there is no analog-to-digital conversion involved. However, many LCD TVs don't display their native screen resolution when plugged into a laptop via HDMI; they scale the image to standard HD resolutions such as 720p or 1080i. The video should display acceptably, but text looks terrible and is difficult to read.
Whichever of the two available options (VGA or DVI) you choose, you will have to use a second cable to carry sound, because only HDMI can carry both video and sound. The cable you use depends on the TV. Most TVs have a 3.5mm jack plug audio input and twin phono inputs next to the HDMI video input. Depending which video input is being used, the TV will choose which audio input to use. The laptop has a 3.5mm jack plug audio output, so you need either a 3.5mm-to-3.5mm cable (for a VGA connection) or a 3.5mm-to-twin-phono cable (for the DVI connection). In the UK, both cables are available from http://www.maplin.co.uk/. If you live in the USA or Europe, you can make use of a suitable search term in the Google search box at the top of this page (with its Web radio button enabled) to find a local vendor.
Playing normal DVDs or downloaded video should work fine, but it won't work for playing high-definition Blu-ray or HD DVD discs, because they are protected with High-bandwidth Digital Content Protection (HDCP), which prevents the copying of high-definition discs by making them playable only on HDCP-compliant monitors/screens through an HDCP-compliant digital video and audio (HDMI) connection, which the laptop doesn't have.
Because of these limitations, it would probably be a better option to buy a standalone HD DVD or Blu-ray player instead. Bear in mind that Toshiba has stopped developing its HD DVD standard because most of the movie studios have abandoned it. Sony's Blu-ray has won the high-definition standards competition. Therefore, in future only new Blu-ray high-definition movies will be in the stores.
