I have a lenovo thinkpad edge 14 and am running windows 7. I recently bought a new battery (not lenovo brand but Sanyo who makes Lenovo batteries). Anyways the battery worked great at first, and my computer actually seems to recognize it as a compatible lenovo battery. However, I took the batter out of my computer and was running my computer just on ac power (an attempt to maximize battery life). Now when I plugged my battery back in it would not charge. It would say "no activity" in the power manager.

When I did a Bios update that was supposed to help with battery problems it worked!! However I took my battery out again to run my computer on AC power and it stopped charging again when i re-inserted the battery. Any ideas how to get the battery to start charging again? I wont take the battery out anymore ill just adjust my power manager settings instead, to try and solve this problem in the future. But as of now, why is it doing this, and can I fix it?

Any help/advice would be great!

Whyd you take it out anyway? seems to me, that if its fully charged, and on AC power, then it should run just fine with the battery in it. I would go into the BIOS and reset everything to failsafe defaults, and see if tha does the trick.

I did not know how to change my power settings not to use my battery unless it really needed charging. I have that figured out now. However my battery was working for a little while and now it is not again. I cannot figure out why, any ideas? I restored the Bios defaults. I am totally stumped.

One reason to leave the battery installed is so that if the power blips out the computer will keep running. Think of it as being a form of built-in UPS. I always leave mine in.

Taking a battery out and putting it back in should be no problem. Many people do that to get longer battery runtime, They have two batteries.

Moving on, How long have you had this generic battery? I would be attacking this problem from the angle of my (New) battery is bad and want the seller to make good on warranty.

It is possible/probable that it is the battery.

Good Luck
