Bios update fails because of missing files

[ru_9]

I have a Zbook 15 G3 and some update service tries to install the BIOS update 01.27 Rev.A.  The update fails because of missing files, according to a DOS screen that comes up after the reboot.  I tried manually downloading the update and installing it with the exact same result.

So I am currently stuck with my PC performing a surprise reboot once a day without any warning or giving me a chance to save any of my work.

Hi

Could you list the files that you have?

Then I will try and create a USB for comparison.

I downloaded sp87948.exe from here: https://support.hp.com/us-en/drivers/selfservice/hp-zbook-15-g3-mobile-workstation/8693763 and then execute it.  It extracted files to C:\SWSetup\SP87948.  On the next screen I selected Update (the default) and then got a warning:

WARNING:

Your current Intel Active Management Technology firmware is affected

by a critical security vulnerability.

Please update the formware and/or implement mitigations immediately.

See: www.hp.com/go/intelmanageabilityissue for details.

When I clicked OK it took me to the website and then informed me that:

This device has BIOS version 01.16

This utility will update it to version 01.27

After clicking Next it copied files and then informed that:

The BIOS update was prepared successfully.

Please restart this device to complete the update.

When I checked the directory C:\SWSetup\SP87948 existed with this content:

HPBIOSUPDREC.exe

HPBIOSUPDREC.log

HPBIOSUPDREC64.exe

HpqPswd.exe

HpqPswd64.exe

N81_0127.bin

WSSP87948.rtf

I closed all my application and restarted the device.

After the reboot this screen:

Informed me of the failure.  None of the folders: Hewlett-Packhard\BIOS\New, EFI\HP\BIOS\New or EFI\HP\BIOS\Previous exists.

Hi

I get the same, so I guess it's not you.

There is an error message saying the files are missing.

I have the same problem with an HP ZBook 17 G4. The bios update complains about missing files at the EFI\HP\Bios directory, which makes sense since there isn't a C:\EFI directory on my Windows 10 computer (even with hidden and system files showing).

It has tried to install the update several times and keeps failing with the same error.
