Default Re: HP Elitebook 840 G3 Caps and Power Button Blinking Doesn't Power On

Isn't the Power Button on a seperate Board?

In this Case it can't be so hard to Figure Out whether the Power Button is working properly.

I believe there is also the Lid-Switch and it is possible you confused the Voltage Readings.

However without Checking the Sub-Board or all Pins of the connector, No progress

Easiest should be to just unscrew the Board and Check directly at the Button. Usually it will Work this way.
