AC Question
Recently my lenovo tab's screen became unresponsive whenever i used it. So i thought of getting it repaired when i got time. About a week later when i thought of getting it repaired, its battery was dead so as i thought of charging it before taking it for repairing but couldn't find my charger. So i charged it with different charger and it was working properly. When i found the charger back and used it, the touch has become unresponsive again. What is the reason?
