Lenovo 500 overheating problem after installing windows 7

Had vista for about 8 months. Everything runs pretty smoothly even Starcraft ii. I had the windows 7 upgrade disk but didn't install until recently. After installing, the laptop overheats by just running. Warcraft iii crashes on a fair frequency too, but seems to have little to do with the overheating issue.

What program should I get to see what is overheating? Also how do i check if my fan is broken?

 

Core Temp

Maybe the default power management profiles are messed up? Did you install the drivers for proper power management?

 

it fluctuates between 54-70C
is that normal?

 

i installed a bios update, and it seems better now than before. It was a lot hotter than 54-70 before.

 

If you are using Core Temp and it shows 54 degrees at idle it is definitely not normal unless your ambient temps are very high. What is the room temp?

Also post the specs of your T500 and it will easier to help troubleshoot.

General comments:

You should run a temperature measurement program that can show the temp of not only the CPU, but also GPU, Chipset, etc. High CPU temps could also be a derivative of high GPU temps.

You possibly need to re-fit the fan/heatsink assembly incl. adding some new thermal paste.

I would also suggest you install Lenovo ThinkVantage Toolbox and use it to run some diagnostics tests.

Last but not least it could be caused by excessive dust build up inside the laptop.

 

And when it's overheating, where are you using it? On a desk or other flat surface?

 

which GPU are you using in the machine ATI or Intel?

 

Just to cover our bases - have you taken apart your laptop (ie: to clean it), and if so, have you fiddled with the cooling assembly (heatsink, fan)?

Also be aware that resuming from standby in Windows 7 on a switchable-graphics-equipped T500 will result in both the integrated and discrete graphics chipsets becoming active, possibly causing increased heat output. Even so, however, your temperatures are not normal.

 

I clean installed Windows 7 recently on an HP dv6000 with ATI graphics, which also previously had vista. It was overheating BAD, and I google'd the issue. The fix was amazingly simple: uninstall the PCI Bus driver in System Drivers and restart the computer. I don't know what the consequences of such a fix are, but it at least fixed the overheating problem.

 

can someone tell me what t.j max 105 c means? is this bad? thanks

 

T Junction is the safe maximum limit your CPU can handle. So your CPU can take temperatures of up to 105c safely before exceeding into potentially damaging levels. Normally most CPUs have a cut off feature which will shut down the PC altogether to protect itself from further damage.

Even so that doesn't mean you should skimp on cooling since you got a 105c threshold, always aim to keep your CPU temperatures well away from the T Junction to prolong the life of your system.
