Hi I have a Compaq presario CQ57 wiith a screen so dark it cannot be seen without a bright light shone at it.
its model no: CQ57-426SA
I have it plugged into an external monitor and thats fine, desktop duplicated on both screens.
I have updated the drivers & bios using hp tool,
I have bought a new led backlit screen & cable, wasting just shy of £85,
this has all achieved nothing, I still have a black screen on the laptop.
It starts up fine, no beeps, runs great no hiccups except that I have to have an external monitor plugged in to see anything!
this is driving me bonkers,
anyone have any suggestions ? (other than bin it)
I would be pulling my hair out, but I`ve none left.......
