I have purchased a Samsung NP300E5X-A01IN Laptop (3rd Gen Ci5/ 4GB/ 750GB/ DOS) in October 2012.
Serail No: HT8K91Lc800437
The battery back up is at most upto 45 minutes.
Found the Issue with in 2/3 three months after purchase and got the battery replaced and the issue continues.
I even doubt if they have changed the battery.
This is ridiculous, Please help me getting this issue resolve once and for all.
