ZBook x360 G5 Shutdown

[OSan]

1. Direct shutdown during operation without any error message. Annoying, and loss of work...

2. Direct sleep mode without any message, annoying...

3. Flashing 'numlk' light. Constant flashing with no pauses. Hard reset removes flashing. Seems ok for some time, then error returns.

Only sw problem seems to be Outlook 365 authentication. Set to classic aut. ir reg. solved the problem. Failed TPM on login. Restored BIOS.... Drivers and OS current....

Upgraded with 512GB SSD and 32 GB memory.

CPUID HW monitor shows temps and volts ok (<80°C, VID#0 etc.0,674V+>1,318V).

Any ideas?

Hi
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

HOW DO I USE DIAGNOSTICS?

HP PC Hardware Diagnostics Windows is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The tool runs within the Windows operating system in order to diagnose hardware failures. HP PC Hardware Diagnostics Windows comes pre-installed on new HP computers, but if not on yours, download here:- http://ftp.hp.com/pub/softpaq/sp93001-93500/sp93457.exe

Have tried HW diagnostic and hard reset several times with no external devices and on battery power only. No faults. As of today there is a new sp with bios 01.07.00 out (15.04.2019). Installed, lets see if that helps.....

BIOS did not solve the problem, problem getting worse, sporadic shutdown every half hour or so. Probably bad power connections inside, or RWM components? All sw installed immedeately before and after uninstalled. Problem occured after RWM upgraded to 32GB (by shop). HW mem diag runs ok.... Num lick flasher for eternity it seems...

PS. Frustrating, this is supposed to be a high end WS, device cost in the excess of $2500...

Seems to be solved. Multiple problmes:

1: Targus Dock (4K 100W power) USB-C not compatible with HP even with separate HP PWS connected directly to WB.. Connected docking using USB 3.1 jack. Upgraded Targus to latest version of soft/firmware.

2: Reset HP BIOS

3: Reset TPM using Windows, uninstalled HP Sure run sw and switched off HP sure run in BIOS. Reinstalled sure run. (had numeorus errors in logs. Help on errors not available: Warning that 'TPM was cleared and existing keys are invalid', and error: 'Fail while retrieving secret'. Warning and error about every minute.)

4: Hard reset.

Seems to work, The lights in Caps and Num seems to indicate some sort of 'unspecified' HW error (TPM?)

[Lil_Boy_Blue]

Secure Boot status perhaps.

Can you get an F2 diagnostic to run?

[OSan]

Diagnostic OK.

Problem returned: Erratic Caps and Num lock lights. Random shutdowns. Event 41, unsolicited power off.....

1. Reinstalled W10 and all apps. Same problem

2. Deinstalled all HP apps.

3. Voila, problem gone......

Update

Seems like the only malware on my laptop was the HP crap... Grrrrrr
