Over the past few months, some HP laptop users have reported issues such as failure to boot, abnormal fan noise, and blue screen crashes after updating their BIOS. Affected models include the ZBook Ultra G1a (with problematic BIOS versions 01.04.03 and 01.04.05) and the EliteBook X G1a (with problematic BIOS versions 01.03.11 and 01.05.00). HP has stated that it has initiated an investigation and advises affected users to contact technical support promptly. It is worth noting that this is not the first time HP has encountered device failures due to BIOS update issues.
