IBM Thinkpad R51 – 176 Error – System has been tampered with
Hi,

I am in need of your help. I have a IBM Thinkpad T41 that I am having a bit of trouble with. When I try to start it up it shows an error message – System has been tampered with, then after that prompts me for a password.

It will not let me into the bios to change any settings and I am not aware of any passwords I have set. Any time I try to enter the bios its refers me to the error message and then the password prompt.

Any help or ideas is much appreciated.

Thanks in advance
