    My A21M will not boot normally but will reliably start in safe mode. I have been gradually upgrading it from Windows 2000 (original release) up until latest SP4 and now it either starts and freezes or never even finishes booting. It must be a software issue but I have no idea where to start looking.

Hello all, I have a IBM A21m with a system password

The Power on Password is set up from the BIOS configuration and the password is stored on an EEPROM chip. Removing the BIOS battery will not reset the BIOS password, there are no backdoor password available.
There is a way to retrieve the password, but it requires a bit of electronic skill and a working computer to achieve this.

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.
