    Hey guys, i have a harsh sound after switching from mains to battery power when only in a specific situation: disconect the mains power cable while in hibernation, coming back from hibernation (on battery power) the laptop makes a 1 sec. long harsh sound. Can it be the difference in voltage when switching from mains to battery or something like that? Can it be damaging for any component?
