My screen keeps flashing when the battery is charging.  The icon that shows it is plugged into the AC adapter flashes on and off too.  I found a post that said an early version of the BIOS had a bug whre t woudl lose track that the AC was plugged in. I have updated both the BIOS and the video adapter to current versions. any help appreciated.

    Good day

     

    Try another charger....I suspect that your charger is faulty. I had same symptoms on my mac and i replaced the charger and its working now.

    it might be the charger but when I put a voltmeter on the charger it seems to be working properly
