Just replaced the battery and its already dead/dying
So over my christmas break I replaced the battery in my dads Alienware laptop, its a 17 something but I don’t remember the specifics. I swapped the battery out and followed the procedure for training it, charge it all the way up, then let it slowly die, then charge it again. Now a month later the battery apparently won’t hold a charge, the laptop says it at 40% but instantly dies when the power cord is unplugged. Any ideas?
