HP DV7 Laptop Graphics Fix Black Screen of Death



would not fix it his way

You will have to replace the HDD

Re-boot the laptop. Verify that the "POST" operation comes on during the restart - if not then you have a graphics issue in the laptop.

take out the battery, then take out the memory. Put one of the two memory modules back in, and turn it on. If everything looks ok, shut down and put the other one back and try again...if everything is ok...then ok. If it doesn't work after the first one, let me know...

now u put out to another monitor by cable if u see screen in there ur lcd have problem, if black too it from ur motherboard , checking

hi,
if nothing(even hp logo ) is not coming on the display then please try this.
1.remove the battery and then press the power button for 30 sec.Again refix it and check.
2.If windows sound is there then this mught be the issue with display.

3.If there is no windows sound might be the issue with RAM so please get it checked.

plz try by resitting the ram if you dont know how to open the laptop then i will suggest you to take it to repair shop.
