When I plugg in the AC Adapter to charge my PC, the Ac is not detected and the PC does not get charged and the Power Led flashes 3 times and stops.
I tested the AC Adpater it has no problem, and the BIOS is well updated with no problem.
Is there a way to Power Reset an HP Probook 450 G7 without opening it and removing the Battery inside?
Thanks.

Hi @soukainaab
If the power led does not light up when you plug in the power adapter, it means that either the power adapter is faulty or that the system board charge circuit may have failed.
If the AC power adapter is not recognized by the notebook, how did you test it?
Testing it with a multimeter for voiltage is not an adequate test.
