hi everyone
so i got a lenvo ideapad L340 gaming laptop and its making strange hissing noise(like electric sparks XD) along with the charger for over a year and lately i could hear some popping noise, its only audible in a quiet room though, anyway so since it was in warranty i got it back to them, they insisted it was normal, until they diagnosed it, they said it was a bad adapter and something with the battery (they didnt specify nor gave me a full report yet), anyway they returned my laptop until they get the parts cause i have work to do on it, but i'm worried and i want to know what could be the cause, and no-one is giving any help yet?
googling it was also useless and all i could find is speakers or fan problems which isnt the case.
any help is appreciated. the more detailed the better.
p.s: its slow as a snail too but works just fine when running games or cad (computer-aided design and drafting) programs.
