Recently my laptop screen went blank after the desktop started scrolling (as in extended desktop) and a message came up saying my power settings (PowerGear4) were corrupted or something and wouldn't work.

I switched it off to hopefully reset the machine but since then I've had no displays, even though everything boots up.

The laptop still gives an out display onto a spare monitor but the main laptop one does not work. I had the occasional problem when the screen wouldn't restore after going on standby and I had to reboot, but now it's not coming back at all.

It looks like a blank screen in standby mode, but not totally off so there seems to be power going to it.

Is there any way to fix this other than send it away to a specialist? It's only 2 years old (may still have warranty).

It is time to have it serviced... warranty or not... Good luck

check and replace your battery and/or converter as appropriate.

Ok thanks!

You may check on eBay for the replacement part(s) you need. I once years ago bought a replacement screen for an old Compaq laptop that was doing the same thing you describe.
