|Using your scenario, unless you keep getting dud batteries then it seems to only leave the possibility of the adapter not being able to keep the battery fully charged. Hard though to really imagine that it would still work the computer.|
When you remove the adapter from the power point on the wall does this also make the screen blank out?
I assume this fault just suddenly came along out of the blue.
As said, let's have the make and model number to see if that gets us anywhere.
Always pop back and let us know the outcome - thanks
