Why won't my laptop recognize my battery/AC adapter?
One day, I decided to use the Lenovo Battery Management and full charge/discharge my battery. The next morning, the battery was discharged, but my laptop couldn't recognize the AC adapter. After trying a number of things, I discovered that my laptop can only charge if I:
1. Take out the battery & AC adapter.
2. Plug in the AC adapter to a wall outlet.
3. Plug the power cord into my laptop.
4. Turn on the laptop
5. Re-attach the battery.
The battery will now charge. But if I disconnect the AC adapter from the laptop or the wall socket, I will have to shut down my laptop and repeat the above steps to charge my battery. Thank you very much in advance and I hope you can solve my problem!
