Product: HP ZBook 17 G3 IDS Base Model Mobile Workstation

My notebook is HP ZBook 17 G3.

 

The keyboard issue manifests itself occasionally. There may sometimes be a few days between two incidents, other times it may happen multiple times in an hour. When I first noticed this behavior, the jam would release itself typically within a handful of seconds. Lately, I've experienced much longer non-functional moments, worst ones being up to around 30 seconds at a time.

 

Similar threads from the past featuring HP Pavilion notebooks:

To get a sense of the depth of the issue, what I've noticed is that during the interruption even the keyboard backlight won't turn on when one of the problematic keys is pressed. Also according to the latter one of the links above where a notebook has undergone a permanent jam, keys won't trigger a beep in BIOS, so it certainly goes deeper than being a mere device driver issue in Windows.

 

I'm hoping there are fixes other than replacing the entire motherboard. My ZBook's warranty is long expired.


I should also mention the BIOS is currently v01.55. There are newer versions, and I'm one reboot short of an update, but I'm pretty sure updating won't do anything as far as the keyboard is concerned – after all, except for the BIOS admin password length check, all changes are related to security vulnerabilities (screenshot below).
