Question about IBM ThinkPad R40 2722 Notebook
I had exactly the same thing happen. I had a free laptop and wound up letting the main battery drain which drained the CMOS battery resulting in the time date issue you see. I am not sure about the tampering message but the key icon means there is a supervisor password set. I looked online for a month to find a better solution but the best I could come up with was from this site. I followed their advice to the letter and it worked.
You will need to know how to solder and not be afraid to take the laptop apart. There is no other way than this to deal with the supervisor password. You will have to flash the chip and read the binary dump. there is software you will need for both of those operations. Once you get the password, you can enter it at the lock screen and then get into the BIOS.
Best of luck. I did it and I ain't that darn smart.
