No danger. Just make sure you don't lose power for the 5-10 critical seconds while doing so. Turn off other devices in your home that are on the same power line, if you ever have any circuit breaker issues.
Try the other ACPI setting first. If no good, then set it back and continue with the bios update.
It's a .exe file you simply run and it does it. Or maybe it extracts to a folder and then there will be simply instructions included. Just be glad you don't have to boot to dos mode to do so, as that has been the standard up until a few years ago when things changed to have Windows installers.
well after some sleep, i played around with the 'default devices' and eventually got the audio working. i could see the audio levels moving with the spoken word on the tv so i knew it was active, just not coming through the proper device. but all good now.
once again thanks for your help last night, i couldnt have done it without you for sure.
You're welcome. Glad to hear that things are well....yep...check your audio settings by right clicking the speaker icon in the system notification area near the clock and in the software you're using too.
