Hello everybody.
I need some help with an IBM ThinkPad A21m, 2628-D1S type.
It have some problem with the CPU fan.After a long period to be off,
it boots ok, and can work for a little while, but suddenly it falls
off. After that, it enters in a quick boot-fail cycle. If i leave it
off for a while, it can boot again, but go quickly do dead again.The
cause is CPU overheating, because the CPU fan dont work. But, the fan
is OK (i tested it ith direct poer supply (5V)), and occasionally it
starts ok with the notebook boot up, but it stops and don´t restarts.
It looks like some power management or thermal sensor failure, or
maybe the BIOS... i don't know. Has anybody seen this kind of problem
before? Can anybody put some light on this?
Thanks from now.
Juan Villagra.
