Laptop fan does not engage when hot, but spins up upon boot
IBM laptop Thinkpad a21m. The laptop fan upon bootup spins up for 3 - 5 secs then turns off. The fan doesn't engage when computer gets hot anymore.(laptop hot on bottom and keyboard) I have replaced the fan unit and still the same problem. Any suggestions on where else I should look to resolve the issue. Also upgraded the BIOS but there are no fan settings there.The fan use to work and suddenly stopped, this is why I replaced the fan.

Did the laptop you got come at least with a windows XP cd? If so boot the laptop off of that and try to install Windows XP and see if it goes thru. Just make sure during the installation you tell it to delete the partitions first and then let it go thru that way you know for sure the hard drive is clean at that point.
It must be a processor overheating problem, check the vents are not restricted and if the fan is always on or never comes on because of a faulty temp setting then theres a overheating problem and the processor will shut down before any damage.
