Laptop Killer: HP's BIOS Update Bricks Some Notebook Models

Users of HP ZBook and EliteBook ran into a critical issue – after installing the latest BIOS updates via Windows Update, their devices refuse to boot.

The problematic updates were released for several models, including the ZBook Ultra G1a and EliteBook X G1a. Owners report that after installing BIOS versions 01.04.03 or 01.04.05 (for the ZBook) and 01.03.11 or 01.05.00 (for the EliteBook), the laptop won’t turn on. In some cases, the system hangs at the early boot stage. There’s a third scenario – fans suddenly ramp up to full speed, then the device shuts down. Microsoft and HP have marked these updates as critical, so Windows Update may install them automatically without any explicit user prompt. Most owners simply didn’t have time to postpone or cancel the installation.

Some users have managed to roll back to the old BIOS version using HP’s network downgrade feature, but there’s a catch: the tool only works when connected via HP’s proprietary USB-C to Ethernet adapter. The system ignores a standard network card or Wi-Fi. HP has acknowledged the problem, but instead of clear rollback or fix instructions, they’re telling affected users to contact support. The company hasn’t released a list of affected models or a detailed action guide yet.

In 2024, a similar incident happened with the HP ProBook series – a BIOS update also bricked those devices. After that scandal, HP claimed to have tightened quality control before releasing firmware. The current situation shows that testing issues apparently remain. The paradox is that just a few days before the flood of complaints, HP announced it was joining the Linux Vendor Firmware Service (LVFS) as a premium sponsor. That initiative is meant to improve firmware delivery and management, but for now Windows users are seeing the exact opposite effect in practice.

For those who haven’t installed the update yet, the advice is simple: temporarily disable automatic installation of critical updates in Windows Update and keep an eye on news from HP. For those whose laptop has already been bricked, the only options are a service center – or, if you’re lucky, your own HP USB-C to Ethernet adapter. Earlier this year, HP quietly launched the OMEN Gaming Subscription service, which lets you rent powerful gaming laptops.
