we’ve had clients have their dell systems bricked from bios updates. it’s not just hp.
at least dell (reluctantly) offered free repairs, even out of warranty, on those models at the time. ‘repair’ being motherboard swap plus shipping both ways if not covered by an onsite warranty plan.
i still have one of those ‘repaired’ systems here. user gave it to us years after it got fixed. it just sat, unused, once they got it back as they bought a new one due to the lengthy turnaround they were quoted.
