My Lenovo laptop does not seem to be recognizing its battery pack and will instantly shut off if it is not plugged in. When I click the power icon to see the power level, it says the power level of the battery is unknown and it does not let me view the battery info. While plugged in, the little battery light on the outside of the laptop flashes as if it is charging the battery, but I don't believe the battery could be charging because I usually keep it plugged in when I am not using it and it is always fully charged!

My laptop suddenly started having this problem yesterday. Because I've been extremely, I had not used it in several days and it had been closed/hibernating during that time. I opened it up to use it just for a couple minutes yesterday and it seemed to be working just fine. I shut it down. Then I turned it back on, and after it had fully booted, I unplugged the AC power to move the laptop away from my desk... but it instantly shut off. It did not shut down, as it usually does when the battery is low, it just went black and then it would not turn back on unless it was plugged in.

I would really appreciate ANY advice on this!!! Is there something wrong with the battery pack? Why isn't the battery being recognized?

Thank you for you help!

Have you taken the battery out and put it back in?

Yes I did. I took the battery out, used a little air duster on it in case there was any debris or anything, and put it back on. It didn't help though. :-(

Sounds like that battery may have met its maker.
