HP-au123cl laptop is buzzing when charger is plugged in
I have a 4 y.o. HP-au123cl laptop running Windows 10 that started making a buzzing noise a couple of days ago when power adapter gets plugged in. If I unplug the adaptor and plug back in, noise stops. The battery indicator in the taskbar stays still in the last few days and says the same thing and does not change 36% available (plugged in) . Adaptor is not hot, cables don't have any damages, adaptor's plug is not loose. Everything seems to be normal besides the noise. Unfortunately, I don't have any spare adaptor or battery to troubleshoot the issue. Is this a battery or adaptor issue? Thank y
