Oct 8, 2018
my idea pad wouldn't turn on. on weekend i was on using it and it had little charge and was really late at night so i didnt charge it till morning but it wouldnt charge. at first i thought it was power outlet, so i checked them and they were fine, i waited for 3 hrs for device to charge and it didnt charge. usualy when my device is out of charge it only takes 3-4 min then it start to show charge sign. i brought a new charger and it still has same issue exept for one moment lenovo sign showed then it shut down, it happened once and never again. please help i dnt know what to do, i had this laptop for a year and few months. I dnt know what to do.. :'(.
