Question about Acer Extensa EX4420-5239 Notebook
Laptop batteries typically need to be replaced every couple of years or so.
Much like cellphones, if you overcharge them then you can ultimately kill cells and keep if from holding any juice.
Good way to keep this from happening in the future is by simply monitoring the amount of charge your battery has while its docked at an outlet.
IF it has a full charge simply take it out and use it on ac power and reserve the battery life for when you need to be mobile.
A new battery can be found either on ebay or directly through the manufacturer. Steer clear from off-brand replacements as I have typically seen a high failure rate.
Hope this helps.
