Hi,

I am having trouble with my Sony Vaio PCG-K215b laptop.

The problem is..when I have it plugged in using the AC Adapter (power supply) the light on the power supply flickers and the laptop changes constantly between the three modes of AC Powered, Battery and charging - every second. However, when the power supply is unplugged from the laptop the green light on it stays constant and doesnt flicker whatsoever.

Also as you may know, when the battery is removed from the laptop and it is plugged in it should run on AC power, but mine doesnt (because it had to be turned off to remove the battery) it just powers up and then straight back off again...Whats wrong with it???

Any Help on the above would be much appreciated.

Thanks Again ,

Dan

I would say it's a loose connection in the power supply- try it with another power supply to see if that's where the problem is. New ones can be bought from Maplin for about £40.
