Qosmio F10 graphics card failure

If you're in the UK you have the law on your side: the Sale of Goods Act protects consumers by requiring goods to be "of merchantable quality". The notorious failure rate of the graphics card on the Toshiba F10 series suggests that this model is faulty by manufacture (have a look on the Toshiba support forums for a few examples in case you need to contact your local Trading Standards Office for support when dealing with Toshiba).

What this means in practice is the machine as sold is not fit for purpose. Don't be fobbed off by "warranty" nonsense either: it is reasonable to expect an expensive laptop to work for seven or eight years, not a mere 12 months. Again, consumer law is on your side. In the first instance your contract is with the retailer, so avoid going direct to Toshiba for as long as you possibly can. Pursue the retailer for a replacement, insisting on your right to be supplied with goods of merchantable quality.

When the original graphics card on the F10 fails, it is replaced by Toshiba service agents with a new motherboard with an integrated Go6600 video card. This puts an extra burden on the battery, reducing its life by 20-25%, so you might push for a replacement battery as well.

If the card is integrated, it will come with the board. Toshiba is your best source for parts, but they don't seem to list your model.
This can be a difficult job, and you might be better off replacing the computer.

Qosmio F10 Has a chipset problem, at all owners in a year-two they leave also a system. The unique way to solder in another a chipset, but service of it does not do video or is not able. I F10 carried the to repairmen of laptops

My video card just went to the happy hunting grounds, I looked around and for the price of this now archaic piece of plastic & wires, have found you can buy duel core with much higher end boards for 1/2 the price. I'm done with Toshiba *2 though, I'll be going Dell.
