I have a ~2.5 year old Acer Nitro 5 AN515-51-76SX that just started crackling out of nowhere. I had it plugged into the wall and sitting on my lap when I started to hear crackling and buzzing noises coming from the bottom of the laptop. I didn't want to damage the computer by messing around with it or using it while it was making these sounds, so I powered it down. It has stopped making noise and is now sitting on my desk, closed and powered off. Any ideas as to what could be causing this? Recommendations for what to do? The laptop has been damaged in the past; one of the hinges on the screen was off-center and caused the screen casing to break apart at the seams, but I had it repaired and have had no other issues. Could it be related to that?
Thanks in advance for any advice and/or troubleshooting ideas!
