Laptop screen goes off while still running

[SanjitAK]

So I have this issue where when i move my laptop, the screen suddenly goes black, while the laptop is still running. And it is impossible for me to get the screen to switch back on. The only method is to power off the laptop completely and then switch it on, but in case i move it again the issue reoccurs. Could somebody kindly tell me what problem i am facing. If i accidentally move the laptop while the computer is booting, the screen starts showing all these blue lines as well.

@SanjitAK Here's what you need to do, to identify the issue and resolve it accordingly:

• If not done already, check if it works fine on the BIOS screen to identify if it's either a hardware or a software issue:
  • If it works fine on the BIOS (Accessed while tapping F10 during a restart) it's a software issue & I suggest attaching an alternate monitor to your device and creating a new user account to check if that works better, for starters)
  • However, if it doesn't work within the BIOS either, I'm afraid it's a hardware malfunction.

While you respond to that, I have a few more steps that should help: 

Perform a power reset (no data loss) using these steps: Click here, proceed to next step if this works

Attempt to run a test from the HP hardware diagnostic tool, using this link: Click here for details.

If the issue appears on the diagnostics, it could again, determine a hardware failure,

If they don't appear on bios & the hardware tests passed: please update the BIOS & Chip-set drivers from the HP website using this link: Click here

if the issue persists, reinstall windows using the recovery partition or the recovery media to fix the issue,
use this link for details on performing the recovery: Click here
