Hi,

 

Have a laptop and when turned on nothing gets displayed in the screen. Power On Led turns on, HDD led turns on and shows activity, CD Rom tray can be ejected. Laptop is a Compal FL90 with nvidia card. Where should I start? Do you have some sort of guide for troubleshooting?

 

Regards.

Will it display anything on an external monitor?

If you shine a flashlight on the display can you see the desktop?

Yeah, I was concurring with him :)

 

I was also thinking (if the external monitor doesn't work) the GPU might need to be reflowed...

Hey thanks for your responces. Sadly, now It got worse maybe is not fixable :(

 

The power led turns on and stays on, the HDD led turns on and blinks for a couple of seconds and then turns off, the cd tray is not ejecting, the fans turns on and then quickly turns off. The screen is completely black it seems that the lcd backlight bulb is not even turning on. I know that the OS is not loading because if I press the power buttom it quickly turns off without blinking or waiting for the OS to shutdown. I'm not talking about pressing the power buttom and keep pressing for few seconds at the first "depression" of the buttom the power led turns off. I will try the external monitor anyways but tomorrow since I don't have one at hand right now.

There's still a lot you can do:

Replace CMOS battery

Check health of the hard drive by removing it and mounting it in another system.

I think the motherboard may be bad, and you might be able to get a replacement for cheap online. Or you could attempt repair yourself... I've had mixed success doing it.
