[Tequegenix]

Some one i know Recently bought HP envy x360

When i restart it it wont show display just a black screen but its on power i can see lights and cam hear the fan rotation. If i hard shutdown it and turn on it works, everything else working fine . Just restart is the problem, if i click win>power>restart . Or after some software installation or driver update it ask you to restart if i let it go restart this happens . I tried firmware upgrade and display driver update . Hope someones kind answer , thank you

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

Hard Reset: Follow steps from the link: https://support.hp.com/gb-en/document/ish_3912651-2318005-16. (do not skip any troubleshooting steps even if you feel steps are repeating)

BIOS default:

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer.
