error booting

I have a T-42 IBM or Lenovo take your pick, but when I use a boot disk and push F-12 to boot to the disk I get an error saying time and date error. Never have seen this before and not sure if this is really the problem?

could this be a bios battery error?
I would've thought so! I definitely can't say for certain but most T&D errors are CMOS battery related... Check the battery (if you can find it, laptops can be quite awkward with things like this!) to see if it's something you can replace yourself.

Chances are you won't be able to though, so you'll need to get someone to do it for you (you may not be able to get the part, even if you're capable!).

Oh and another way to check would be to modify the BIOS settings in some way, power the machine off completely from any power source, and see if it keeps the changes you made or not...
load your bios and check all settings look valid in there try this before you boot to disk.

if bios wont load then its the battery fault as above or the bios has become corrupted check teh following for resolution
