Hi all. I've been having issues lately with an otherwise great laptop, a Toshiba Satellite L850D. It's running an AMD Vision A8-4500M, which runs extremely hot when plugged in, and very hot when not plugged in. It's switched off, bypassed the usual BSoD one gets when a computer overheats, and refused to switch on until it had cooled sufficiently.

Thanks for the help, in advance.

 

Graphics Card
AMD Radeon HD 7640G+7610M Dual @ 1GB / 512MB

AMD Catalyst Driver Version, and Driver History
not sure

Operating System
Windows 7 64 Bit

Issue Details
Laptop has overheated three times, playing fairly lightweight games. It switches off, and will not switch back on until it has cooled sufficiently. I throttled the CPU back to 1.4Ghz to prevent this overheating from occurring, but with the coming Australian summer, I would like to fix this problem.

Piriform Speccy reports that the A8-4500M is reaching a whopping 105C-115C when idle. Core Temp did not report, because it has an issue with the motherboard used in this laptop.

Motherboard or System Make & Model
Toshiba Portable PC (Socket FT1)

version PSKB4A-005004

Power Supply

not sure, standard stock power supply that came with the laptop i guess


Display Device(s) and Connection(s) Used
stock monitor that came with the device, listed as "generic PnP monitor on AMD Radeon HD 7640G

Applications and Games

Civilisation V, Team Fortress 2, Left 4 Dead 2, all latest versions.

CPU Details
AMD Vision A8-4500M APU @ 1.9ghz quad core. Throttled back to 1.4ghz to avoid overheating issues.

Motherboard BIOS Version
Insyde Corp 1.2

System Memory Type & Amount
- 8GB DDR, came with the laptop.

Additional Details
Scanned with Comodo Antivirus and MalwareBytes to make sure there's nothing infesting the CPU - but it's running very hot even at low usage.

Take it apart, replace the thermal paste the unit came with it. And clean out the heatsink. 

Thats the only thing you can do.

Cleaned out the CPU and the fans with compressed air. Can't get at the heatsink on this model, but got a fair amount of dust out from the compressed air blasting. Speccy reports 97C, so it's dropped by a fair amount, but it's still high. CPU-Z doesn't come up with any temperature, which is apparently an issue with the motherboard I'm running.

Okay, I used that CPUID thing, and it reports the same absurdly high temperature. Now, the computer itself isn't actually all that warm. I think the issue is the thermal paste, or the voltage on the motherboard or something.
