U330 cannot turn on after plugged in AC adapter

[ Edited ]
I'm using Ideapad U330 with latest BIOS (v67).

- If I plugged in the AC adapter while the computer turned off, then it won't be able to turned on anymore. And there won't be LED charging status.
I have to take off AC adapter and battery for about 3 minutes, then it can be turned on normally using battery.

- But if I plug in AC adapter while the computer is turning on, then I shut down Windows, I still can turn it on with no problem (as long as AC adapter was not removed).

- If I unplug AC adapter while the computer turned off, it also cannot be turned on. I have to remove the battery again.

- But sometimes the problem doesn't occur.

Now I have to turn on the computer before plugging in or unplug AC adapter everytime.

Does anyone have this problem?
(P.S. Sorry about my english.)
