I aquired a few Hp nv6400 laptops none of them power on .
I'm using a Dell 19.5v power supply on them none of them power on do I need to get a HP 18.5v supply. I tried the static discharge with holding the power switch for 30 seconds that didn't work. Can you give me some suggestions on what I could do to fix them.
Sincerely,
Michael BeDell
Is this a good question?
