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.

    This is a rather old laptop and the supporting BIOS doesn't have a fan setting. I did upgrade the BIOS to the most recent but the problem still exists. You mentioned resetting the program. Are u meaning upgrading or ?

I have IBM 2628-DRU Think Pad A21m And this PC sets password for BIOS, and I can't use it, because I don't know the password


To reset the BIOS read the information from this link.

In case of your laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

My ibm laptop contionusly beeps and says power scource is battery,when i press esc, it boots normally and shuts down in about 15 mins to half an hour


Either:
A. Bad battery
Or
B Bad power supply.

Sounds like the battery isnt charging correctly , the beeping is warning you it is running out of power.

Take the battery out , and boot normally with the ac adapter.

Does it work?

If yes, Get new battery. about 70-90 dollars.

If no. Get new ac adapter. 20-40 dollars.

ThinkPad A21m won't boot into Windows


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.

Always shutdown my IBM ThinkPad A21m 2628 PC Notebook


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.
