Black screen after HP Logo

HP Recommended
HP EliteBook 840 G7
Microsoft Windows 10 (64-bit)

Hi,

 

We bought 40+ HP EliteBook 840 G7 for a customer. Now one after one is not starting up anymore but shows just a black screen after de HP logo.

Safe mode is possible, normal startup isn't.

 

What I tried till now:

- uninstalled latest updates

- BIOS Update

- Disabled everything in the auto start

- deleted every display driver

- nothing to be found in the event viewer

 

Software installed, but never had any problems with these:

- Office365 Suite, Adobe Reader, 7-ZIP, VLC and an antivirus software (SentinelOne)

 

Resetting Windows works, but after some time it happened again.

Does anyone have another idea?

 

Thanks

Hi @hmrb 

 

Based on your description, this is a software problem - Windows issue, Windows update or drivers. Drivers could be for hardware, could be software ones (like security ones).

 

Windows is not a living organism, so things don't change on their own (still no AI in it).
So this means that something happens which causes the problem - software installation, software update, driver update, Windows update and whatever happens causes some problem or incompatibility.

 

  • Use Windows 10 2004 or 20H2 only
  • If you use Windows 10 Pro , use group policies (gpedit.msc) to limit what gets installed, you can stop driver installation from Windows Updates. stop automatic updates, install updates at once only.
  • Do not use 3rd security apps on at least one-two of the PCs to see how it goes.
  • Use HP Image Assistant to download/install all HP drivers, software, ESU, etc and do it once right after Windows is installed.
  • Activate Windows System Restore- and often create restore points and before any change, so that you are able to revert back.
  • and like that... you will be able to find what causes the issue

 

Hope this helps you.
