My HP dv5z-1000 laptop is having some display issues. At completely random times the display will go blank, while the backlight and the computer itself remains on and running. Sometimes it will do this as soon as I turn it on, other times I can use it for hours without the problem popping up.
Before my battery died (2nd one in 2 years) I could run it on battery for hours and it never happened. HP Tech is completely clueless and wants me to send it in, which is laughable.
Steps I have taken so far:
Tried Updating Bios
Resinstalled Power Management and made new power plan
Reinstalled Display Drivers
Have run Kaspersky and found no Viruses
Hooked it up to my TV as a external monitor and couldn't get it to replicate the issue.
More Interesting tidbits:
When I prop the back of the computer up, it seems to help the issue sometimes, so It could be an overheating issue I guess....even though it sometimes does it within minutes of being turned on.
There was one instance where the computer turned itself off after giving a BSOD, which then threw up an error code upon restart. A few days later it turned off and when I turned it back on it went into Check Disk mode but as far as I could tell that was the extent of the error.
Essentially, I am puzzled. I'm wondering if the hard drive is failing or if the motherboard is going dead. Or perhaps my charger is causing the problem somehow....No idea.
