Overheating Laptop...advice?

post #1 of 7
Thread Starter 
I have a Toshiba A75 S226 that I received for free from a customer.

When I first got it I did a complete tear down, cleaning with compressed air, and re-sealing of thermal paste with silicone paste.

I noticed though, when I watched fullscreen video, the laptop immediately shuts off. I'm guessing this is a temperature problem, because if the laptop is cool it takes a while to do, but if you immediately restart it does it very quickly.

I disassembled the laptop again and did another cleansing of dust, and resealed the CPU with silver based grease. However, I noticed the ATI chip has no heatsink at all. There's not even holes to mount one.

So my question is...how would I go about cooling the a chipset with no mounting holes? (There is a decent amount of clearance for a heatsink though).

Thanks for reading.

Not sure about cooling the GPU to be honest - maybe mount a small heat sink using double sided thermal tape so you don't need mounting holes.

However, a buddy of mine got a Toshiba Quosmio X305 running a GTS9700M and had EPIC overheating issues for a long time...until he installed Windows 7. I can't explain why, but the switch to 7 from Vista sorted out all his overheating issues, made his battery last almost twice as long, and all his games ran better. Night and day.

If you have the option, I would highly recommend giving it a go.

Hmm...it's a pretty old laptop and I'm running Linux Mint 10 on it.

I have Windows 7 here...but idk...I'm unable to probe any temperature sensors in linux either (to make matters worse)

Gah, still randomly shutting down. I almost wonder if it could be something else besides a heat problem...

If you watch any video, does it shut down, or is it just a fullscreen video? What is the source of the video?

Have you checked the dump file when windows crashes to see if there are any interpretable errors reported?

If the video chipset wasn't cooled before, it probably doesn't require any sort of heatsink. I'd blame that nice hot 3GHz P4 as the cause (rather than the gfx chipset).

I just looked up some reviews about this laptop, and others report the same thing--shutdowns due to heat, and apparently Toshiba has warned of this. I think the best idea is to get a laptop chiller pad to circulate air underneath the laptop--you can pick one up for $10-15. Last one I had was a Targus, and it worked just fine.

Mainly just fullscreen video after about 5-10 minutes.

I'm running Mint Linux and I'm not sure where to find such a log.

Unfortunately I'm already using one of these laptop cooling pads, and I've resealed the CPU with silver-based grease. I am at a loss at this point.

Oh, already using a chill pad? That's too bad. Made sure that the retention mounts for the heat sink are tight? Otherwise, I can't think of a different way to deal with the heat issue other than removing as many of the chassis panels on the underside as possible and seeing if that makes a difference?
