You can't. You will need to buy a new motherboard. The solder contacts are between the top of the board and the bottom of the chip so you can't even see them.
Rarely (as with the XBox red ring repair) you can apply an even force to the top of the chip to try and get it to contact. If you’re lucky and the motherboard boots then let the chip overheat for about 20 minutes (i.e. no heat sink or fans attached to the graphics chip) which should reflow the solder.
To be honest though, this is unlikely to work on anything but the XBox as it does not have a proper heat sink and plate under the PCB to clamp it to. This is in fact what causes the problem.
With so much demand for 'smallness' these days, computer manufactures are not allowing the space for air flow or heat sinks to cool these powerful chipsets. This is especially true of Nvidia that build superb graphics cards but they do get hot. This is not Nvidia's fault as if you buy a graphics card for a PC it is already housed with a fan all designed by Nvidia and I have never had one fail on me in 10 years. Laptop company's though only buy the chipset's and install them onto their own motherboards without thinking too much about the quality build and lifetime of the system rather than how small and lightweight it will be.
If you want a system with a decent graphics card then buy a PC. If you really need a laptop then I can only recommend one from the HP business range as they are built for work and not entertainment so doesn’t die easily.
Before you give up though and sling it out, put a sheet of steel over the whole board so that it is only touching the top of the graphics chip and try heating it (moderately) with a paint stripper heat gun. Make sure you let it cool totally before moving though as you will have all the tiny SMT (surface mount technology) resistors falling off. I have fixed about 4 out of 10 this way and the longest one lasted for was 4 months and packed up again so the odds are bad with a bleak future ahead and it's more likely you'll melt the PCB first anyway! But if it's going in the bin and your bored...
Hope this info helps someone thinking of buying a laptop anyway.

Phill.

Since the video card on this computer is built in to the motherboard and there's also no way putting a external video card on this unt, if you want you take first this computer to a repair center and let them fix the bad video card that will be much cheaper compare to getting a new motherboard, but the wrose case is you need to get a new motherboard for this computer......

ATI Mobility Radeon HD 2400


It is not possible to replace a graphics card on a laptop. The video chip is part of the motherboard and most likely the fix is a replacement motherboard.
How do you know it is a video card fault? If could just a back-light problem. Please follow my instructions to determine the fault and possible fix - click on this link :-

Graphics card driver for Sony Vaio VGN-FZ410E


Sorry but most laptops come with video on board and not a separate video card to upgrade to another card while not impossible would be very expansive. you would have to get a desktop computer with separate video card installed to play your games
please post rating thanks
