Model Number : W6T29PA#ACJ

OS: Windows 10 home

Age : 1 year and 5 months.

Error :  No error message displayed.

It  turns off without any warning. 

It randomly turns off like at like 76% or 83%.

And when I turn it on again, It is unable to boot completely and turns-off again. 

I have to plug in the power supply to turn it back on.

One more thing : Recently I have noticed that charging of the battery fluctuates(sometimes it shows not charging even when plugged in). I have run troubleshooter and tried plugging the AC adapter into  a different port but none of that helped. 

I did also uninstalled the ACPI adapter drivers and reinstalled it, but it didn't helped either.
