My friend gave me a Dell Latitude D510 to take a look at. There is no power light on or any activity at all when the AC adapter is plugged in (also nothing with just battery which I assume is flat).
She says there was no warning signs and one day it just stopped working. Dell told her that she will need a new motherboard (in which case it is basically written off). I have read elsewhere that there is a known problem with this model involving a flaw with power jack resulting in the need for a new motherboard.
Does anybody else have any suggestions please?
