After that it's possible to update the BIOS by an BIOS option loading this file. However, I'm allergic to the inflationary trend of recommending BIOS updates when something goes wrong without even knowing if it's BIOS related. I strongly recommend to read the changelog of available BIOS updates, to see if something related to the issue is fixed, if not consider to stay away from an update. Apart from my recommendation vendors usually recommend to update the BIOS only if something is fishy, because they claim that a BIOS update is risky. >From the OP's description I've got the impression that it could be a kernel regression. Muscle tension is also said to be a cause of tinnitus, but initially it makes more sense to see an ENT doctor than an orthopaedist. IOW If the problem occurs after a kernel update but goes away after a kernel downgrade, it's not that unlikely that the kernel is to blame, so a BIOS update to fix the problem doesn't sound particularly promising to me, but a BIOS update could cause additional problems.
