Sorry if this is posted in the wrong spot, I'm new. I have an Acer Aspire 7736Z-4088 laptop. I do not remember the year it was purchased, but it has been a few years. This laptop and I have a love-hate relationship with each other. The laptop has sat idle for months because it stopped charging and I could no longer turn it on because the battery was dead. It has stopped charing before and I left it for months until it randomly decided to start charging again. Before it stopped charging the most recent time, the laptop would only charge if the charging cable was in a certain position. The charger I am using is a Targus charger. When plugged into an outlet, the charger light turns on, however when plugged into the laptop, nothing. Is my laptop battery completely useless and needs to be replaced? Or is it something to do with the charger or charging pin?
