Respuesta a "My chromebook's audio coming out of the headphone jack is just one ear"Check the other answer first. It may be a depth perception driver error that is resulting in the weird audio. It happens on my chromebook sometimes too.
Respuesta a "Why is my dell chromebook 5190 2 in 1 not charging?"May be a faulty battery that isnt accepting the charger port, or it may be a damaged motherboard or the battery is burnt out completely. Try replacing the battery first.
