Aspire 7. Electric Shock while charging , also making weird noises
Hi all!
I have experienced quite a weird problem with my Aspire 7. It actually is treating me with a bit of electricity once a while when plugged in, also making weird noises when the screen refreshes (using mouse, writting, watching video etc). It is like buzzing, but very quiet and I haven't noticed it at first. The thing is, that I work at complete silence at nights and it is ***** me off then. It doesn't make any sounds when unplugged. Is it normal or should I have it repaired? Also, will the fact that these sounds are hard to hear in normal conditions (i mean while talking etc) make it harder for my reseller to admit I am right? I would rather avoid 'go to hell it's nothing' scenario
Thanks!

Static discharges often happen in very dry climates/environment, make sure the power adapter has a grounded (3-pin) AC power plug and that you use the grounded electrical wall outlet and not a power strip or extension cord. Touching a large metal object before opening the laptop lid also helps. Keeping the power adapter/USB-C charger plugged-in 24/7 will keep the battery 100% charged and won't fast charge which is probably causing that noise you mentioned.

Check the coil whine. It often comes from GPU, but not necessarily. I think that's why it's much louder when on big load, and that's why it disappears when there's no voltage on the chassey. It's not directly connected to the electric shock, it's more like its effect. But not sure if it's because of the chassey or it's just the CPI/GPU having more power then.
