I bought a x220t last September. Typically if I unplug the tablet with a full charge, the battery indicator will show somewhere between 4-6 hrs. If the tablet goes idle, this number would shoot up to 16hrs or something rediculous. I never timed the battery performance, but I was never left with the feeling that I was being cheated. ie I think I was getting that 4-6hrs of life.
Starting yesterday, I see that my battery life is showing much less after a full charge. For example, this morning after unplugging the tablet, my charge was under 3hrs. Yesterday I noticed that while working on the tablet, my battery dropped really fast - it went from 2 hrs to 1.5hrs to .5 in what seemed like 30min. Again, I wasn't timing it (didn't realize there could be a problem).
I'm going to keep a closer eye on this, but I would also like to hear if other people have experienced anything similar. I don't recall installing any new software that would cause a change in behaviour.

As I understand the battery backup is not proper and it reduces suddenly.
Kindly update the BIOS and check if the issue gets resolved.
