My friends laptop (same as mine!) is having a weird problem with the screen. When the power adaptor is plugged in, the screen is ok for 10-20 seconds, but then it suddenly goes black as if it switched off, however, you can just about see stuff on the screen.
Every time this happens the laptop needs to be rebooted. With the battery plugged in (on its own) there is no problem.
The Fn+arrow keys doesn't have any effect. At first I thought it might be the power adaptor that's causing the issue, but it seems to work fine on my laptop. My power adaptor on his laptop causes the black screen as well..so I'm guessing it must be something hardware related - any ideas?
Ps. The laptop is out of warranty.
Thanks!
