lenovo thinkpad T61 blinking battery light, new battery
Posted on 2010-11-17
I replaced a battery for a customer in a Lenovo ThinkPad T61 about 2 months ago. Charged up and was working great. The laptops back and I'm stumped.
The battery light on laptop is blinking orange/green. Windows says that the battery is "On AC Power". But the battery is plugged in. And windows recognizes the battery. But it has a charge of 0%. If I click on the battery in the power meter window for more details....it says "Power State: Online, critical" If the computer is unplugged from AC, the computer immediately puts itsself to sleep. So the battery is working...just not charging. Or it would shut off instantly, rather than hibernating.
What could be the problem?
It's a new battery, it tested fine before, windows recognizes the battery, but it simply won't charge.
