E420 overheating

I have a quite possibly big problem. I have E420 1141-CKG model and each time when computer resumes from either standby or hibernate,the fan does not work and laptop heats up really really bad. It still works and plastics under become hot and you can feel a smell of hot plastic. If I restart the laptot the fan works fine and if I switch graphics from intel to ati the fan comes up again.But if not restarted the fan just doesnt work.I think this amount of heat will damage the laptop quite soon. Is there a fix for this problem?

Re: E420 overheating

You need to update the BIOS to resolve the issue.

 

Kindly download the BIOS from the mentioned below web link.

Re: E420 overheating

ok,since support from lenovo is..well....crap.bios updating didnt solve anything.so is the vga driver update install reinstall etc...even reinstalled windows 7.but recent update from microsoft in windows update for intel integrated vga solved the issue...fan kicks in perfectly when under load no matter if it is from standby or not.and switchable graphics work.so,lenovo,please,check your vga drivers since it is obviously software related issue,not bios...
