Anyone answer why my system continually pops up a nag screen telling me to connect a higher power supply to get full performance?
Running it on the standard supply does it. Connect it to the G2 Dock with the higher rated supply - still get the same nag!
Really annoying

There should b a setting in the device BIOS to disable AC Adapter warning.
How old is the charger? Have you taken a multimeter to check for proper read outs?
Is there a BIOS Update that may resolve this issue?

Should have mentioned this has only happened after HP replaced the motherboard.
Update : found out why I'm (probably) having issues. The laptop was bought as a ZBook Studio G5. The motherboard that HP fitted, under business warranty, is from an EliteBook 840 G6. To say I'm raging would be an understatement 😞
Also found out that the system flat refuses to recognise the onboard speakers or microphone so i suspect that the new motherboard is not working as it should.
He did supposedly update the BIOS when he rebuilt the system.
I've raised another case for the speakers etc so see what happens.

What is the system details in BIOS? Granted BIOS can be reprogramed as those boards could very well be similar.

Bios says Zbook studio, Win reporting (PC/Manage) states Elitebook.
A 2020 ZBook studio has 4 SODIMM slots enabling 64G of RAM. An Elitebook has 2 slots enabling 32G. The ZBook has installed by factory slots and mine was supplied with 32G of RAM. If i take out the modules in the user accessible slots the machine beeps like crazy and wont start. No memory fitted. Hence it only has two slots! It is NOT a Zbook Studio MB.
Phoned support today, honestly!! Bang your head from a brick wall. "I will do everything to sort this today!" aye ..... he went home. No new case raised as promised. No email as promised.
And still doesn't fix the issue that none of the audio on this MB works 😞

Download https://www.cpuid.com/softwares/cpu-z.html and export the data and upload here. It's possible the 2 DIMM slots that you can't see are there but not populated.
