Laptop hibernates without low battery notification

hari_7189

Hi All,

 

I own an Acer Aspire V5 571G and lately whenever the battery reacches around 12 to 15% charge, it hibernates on its own without giving any low battery notification. And when I plug the charger and turn my laptop back on, the battery shows 5% charge. I have no idea where the remaing 7 to 10% of the charge went!

 

I tried formatting my system thinking it would rectify the problem but it was of no use. I took it to the authorised Acer service centre here and they formatted the OS and updated the BIOS. The problem was gone for a while but it came back after about 2 weeks.

 

The options in the advanced power options are all correct ie: low battery notification: ON, low battery level: 10%, reserve battery level: 7%.

 

Any suggestions? Any help will be greatly appreciated. Thanks

have you tried setting the alerts for higher % of battery if it is getting out of sync like 20% and 15%
