HP Probes BIOS Update Failures on AMD ZBook Ultra G1a and EliteBook X G1a

Posted on
HP is investigating BIOS update reports affecting AMD-based ZBook Ultra G1a and EliteBook X G1a systems, including boot failures, crashes, and instability.

Quick Report

HP says it is investigating reports that recent BIOS updates are causing serious issues on some AMD-based ZBook Ultra G1a and EliteBook X G1a laptops, including frozen boot screens, crashes, louder fan behavior, and blue-screen failures. The affected firmware was reportedly pushed as a critical update through Windows Update in some cases.

Reported versions include 01.04.03 and 01.04.05 for ZBook Ultra G1a, plus 01.03.11 and 01.05.00 for EliteBook X G1a. Some users reportedly recovered via downgrade paths, but the process appears inconsistent and sometimes dependent on specific recovery hardware, including HP USB-C Ethernet adapters in some cases.

The incident renews concern about automatic firmware distribution for business notebooks, especially where rollback paths are not simple for end users. HP has acknowledged the reports publicly and said it is looking into the issue.
