Hi everyone!
So, you don't see a screen when you start the computer? Well, I had a similar problem. I had an HP Pavilion Ze5300 and it turns out that the backlight/bulb and inverter was bad, so check that.
Otherwise, I could be the Mobo.
Ps- I have a problem! My laptop's power board is a bust! It is seperate from the mobo itself, and I can replace it, but has anyone had any success in doing so? I have a dell latitude d610.
Thanks
