I have a 2 year old acer aspire 5750g and when I plug the charger into my laptop my power button, the light bulb and the charger light all flash on and off and my computer won't charge but sometimes when I play with the charger I can get the laptop to charge for a minute or two then it disconnects and they all start flashing again. I thought it might of been the charger so I replaced it and the same thing happened. What's wrong with my laptop?
