Why does my laptop randomly shut off?

Davidnj11 · Jan 17, 2015

I had a Pentium B970 in my laptop before I ordered an i3-3130m, which ran fine. I actually found out that I'd been running it without any thermal compound, but it still ran fine oddly. Now when I try to use my new i3, it runs great, but then it shuts itself off as if its overheating. The thing is, it stays around 40 degrees Celsius and reaches 60 at max. I'm not sure as to what could be the issue since the Pentium doesn't do this, but I've got another identical i3 that does the same thing. Any ideas? I'm using arctic silver 5 thermal compound and a Toshiba Satellite C875-S7205. Thanks for any help or ideas!!

Does the bios and power supply in the laptop officially support the new cpu?

Davidnj11 · Jan 17, 2015

Hmm. Well there are other models of this laptop that run with the i3. It could be second generation though. Lol think a bios update could help fix the issue? It doesn't shut off in the bios or when its in sleep mode.

You might try - but the vast majority of laptops have a very specific bios for the cpu they come with (and the cpu was never meant to be upgraded).

I believe it is supported, but maybe not. It doesn't give me any error codes or anything when booting and in the bios it displays the right information on the processor description.

I updated the bios to the latest version available, yet it still shuts off. It just shut off a few minutes ago once again. I have no idea what it is lol.

I dunno - could be a power thing if the i3 is more than the Pentium. Or, unless you found somewhere that said that bios supports that cpu then maybe it just doesn't know what to do with it.

Davidnj11 · Jan 18, 2015

Ahhh okay. Think there's any hope of fixing it? It's got the same power usage as my Pentium and the requirements and socket types are identical..

J_E_D_70 · Jan 18, 2015

If you go back to the pentium does it stop crashing?

Davidnj11 · Jan 18, 2015

Yup. I'm using it now and I've never had an issue with it. It runs at even higher temperatures too. My chipset driver was the standard driver so maybe that could be it. Doubt it, but it's worth a shot. Lol after I get the i3 in again to test it, I'll tell you how it goes.

Well good luck!

Whelp, I did some research and the chipset I've got is an HM70 Chipset that can only use Pentium and Celeron processors! Bad news, but at least I know what the issue was.

Thanks for your help!

Doh - sorry to hear that. Knowing is half the battle.
