Don't understand this one.

Have an N610c notebook.

When I switch it on I get the Compaq logo and the usual "press F10 to enter
setup" Then the screen goes blank and XP boots up. The reason I know this
is because you hear the XP startup tune.

Also if you do press F10 to go into setup the screen goes blank.

If you plug in an external CRT monitor you can see the bios settings, or if
XP boots up, you can see the XP desktop.

So to summarize - when you switch on notebook the screen has a brief sign of
life and then nothing.

Has anybody any idea what is wrong?

Thanks in advance.
