HP Zbook 15 G3 won’t boot

HP Zbook 15 G3
Microsoft Windows 10 (64-bit)


Randomly my HP Zbook 15 G3 did not boot anymore. I tried to force a hard reset and I removed the battery and tried to boot it up with only power from the chord. However, it still does not boot. Has anyone suggestions to try or should I give up?

Thank you for helping!

This will not work for everyone, but you may be lucky?

HP Notebooks and Mobile Workstations -
No Power, No Boot, No Display When Power Button Is Pressed

NOTE: Be sure the battery is installed in the computer and it has sufficient power before continuing. Due to the design of the Embedded Controller/Keyboard Controller, the power supply must be disconnected and the computer must be powered with battery power to reset the Embedded Controller/Keyboard Controller.

Unplug the AC power from the computer.
Press and hold the power button for more than 12 seconds.
Release the power button (after at least 12 seconds).
The computer will power on and should boot normally after releasing the power button.
Re-connect the AC power to the computer.

NOTE: In case the battery is not charging after performing the steps to reset the Embedded Controller, unplug and re-plug in the AC power again.

Little Boy Blue, come blow your horn.
