Laptop problem help needed

[joshb21]

Hi had my acer aspire 5720 now for 2 years and now fairly suddenly my battery even at 100% charge only has 30 minutes of battery life. Obviously this hasn't always been this case. What has happened is it my charger, battery? i have no idea

Sounds like your battery is no longer holding a charge... You might also find this link interesting Understanding Lithium-Ion and Smart Battery Technology

Hi sorry about the late reply link not working but would it be a simple matter of replacing the battery and if so how much would 1 cost
