Question about HP Pavilion dv9000z Notebook
THE BLUE LIGHTS ARE ALL ON AND THE ON SWITCH IS FLASHING BUT NOTHING WILL COME UP ON SCREEN -AND IT WILL NOT POWER DOWN EITHER
Firstly you Should try reseating the RAM.
You can also try booting with only 1 RAM mod connectet at a time. Make sure to check the working one in both slots incase the mainboard is defective. If the unit boots with one of the RAM mods in both slots the other one will need replacing.
If this doesnt work the unit will need service.
