I've only used the laptop for about 2 years now and it only goes off abruptly after about 20 minutes of usage even after full charge without any warning. Could i consider buying a new one really?Batteries die, sometimes after only a couple of years. Another possibility is the power block is misinforming you but buying a new battery is the best bet. Spend decent money for the new one. Cheap ones may be a clone and some causes fires.
I've had to change your name. Lots of folks would like to do that, my included, but we can't condone advertising.
