I have windows 7 home premium on Auss U47VC laptop.

Recently, what happens is that when I shut down the windows and the charger is plugged in, the charger light is constantly red during the time it's being charged and then turns green once it's fully charged. So far so good.

The problem is when I turn on the computer then most of the times the red charger light starts flashing and so does the light on the screen so it drives me crazy. Sometimes this doesn't happen but most of the times it does happen.

Apparently it's a common thing among Asus laptops. See for example:

I've tried shutting down, removing the battery, holding the power bottom for 30 sec, placing the battery again but it didn't solve the problem. Help!
