I recently bought a Toshiba L670-14P with the 5650 HD and all was fine till recently as when I have been playing WoW (at recomended levels) and the laptop has been shutting off. When this happens I have to remove the ac adapter and then reinsert it to get the laptop to boot up again.

I've been on the phone to Toshiba about this, updated the BIOS twice, and sent it to their tech guys for a repair. Apparently, they found nothing wrong with it, cleaned it out, updated the BIOS and sent it back to me. It worked fine for about a fortnight then it starts again.

On idle, the graphics card is running at 60-70°C. When I start playing WoW however, the GPU temperature jumps up to 80-95°, sometimes hitting 100°. I've been back on the phone to Toshiba, and they say that there is nothing wrong with it, and that if I send it to them and they find nothing "wrong", they'll charge me £35 for the privilege.

So far, I've got a few theories as to why its running so hot:

#1 - A particulary stubborn piece of lint/dust in the GPU fan

#2 - The laptop is currently using a universal power supply, as the genuine one got damaged. This runs at 19v and 4.5a whereas on the laptop it shows it needs 19v and 3.9a. Perhaps the extra ampage is making the GPU hot?

#3 - Something to do with WoW? I've seen lots of people having this trouble since patch 4.0.3

#4 - Bad laptop design?

Just for clarity, it seems that the hottest part isnt the fan on the left hand side (which seems to be the major one) but an area directly under the mousepad on the underside of the laptop (perhaps the GPU is here?)

Im just wondering whether or not its worth sending my laptop to Germany again just for Toshiba to deny all knowledge and charge me, or if its something I am doing....

Any help/ideas would be great, because I saw one forum post saying that their card only ever reaches 65°

PS.

#1 - Laptop is running on the "high performance" powerplan, so is the ATI Catalyst software.
#2 - Laptop is used on a normal wooden table, never used on my knee or cushions of any type
#3 - It's still under warranty

PPS.

Just noticed that the processor temperature gets rather high as well sometimes, mid 90's, maybe this is why its shutting down?

Problem solved, there was lint and dust "behind" the fan, so using air was never going to work, had a local tech shop open it up and clean it out, working at optimum temp now.
