Hello, 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.)
