Hi there,
Having a bit of an issue. Just installed am SSD in an HP Probook 4730s laptop (old HDD failed). I have flashed the BIOS to the most recent version, and disabled all the boot methods that don't apply, but for some reason, I get an odd issue.
The BIOS screen loads, then goes to a battery error (which is annoying, but I don't think it's part of the problem). When the error dissappears, the Windows 10 logo appears for a second. The screen then goes blank, and stays that way for around a minute, and then boots into Windows rapidly. It's the bit in the middle I don't understand, it just sits there not doing anything.
Hoping someone can help me?
Thank you
T

This is to do with the ultra low power state in the latest display drivers from AMD. I have the same model laptop.

To disable this, set the following registry key

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001

and create the following dword if not there already

EnableUlps

And set it to 0

Or copy the following to a txt file , save it, then change the file type from .txt to .reg. Double click to import in to the registry.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001]
"EnableUlps"=dword:00000000
