My computer is having issues with recharging. It can take a whole night to recharge the computer fully. If I recharge the computer while using it, the battery level doesn't increase, and the computer gets laggy (but if I stop recharging, it operates smoothly again). The recharging port and jack get so hot that I might get burnt touching it for a long time. So is it the recharger that is faulty, or is it something else?
