How can I test the close cover switch on an HP zx5000 laptop
Posted on 2007-11-18
I have an HP zx5000 laptop with a backlight issue. The laptop will work on an external monitor, and I can see the dim desktop on the lcd screen when viewed with a bright light at an angle to the lcd screen.
The problem is that while this seems to be a classic inverter failure, I can sometimes get the laptop screen backlights to turn on by pressing the small lid switch pin. This happens occasionally and when it does the screen will stay lit for 10 seconds and reverts to an unlit screen.
I am still thinking its the inverter, has anyone else seen this?
