Looks my battery is not Calibrated because after 6% it tends to last 1 hour.. which is kind of weird. How would I Calibrate the batter in WIndows 8.1?

You can re-calibrate your battery by following the steps below:
Important: Re-calibrating your battery may take several hours depending upon your system configuration as well as the age and life of your battery.
1. Turn your device Off. Then plug in your AC adapter.
2. Let the device fully charge, until the battery LED turns Off.
3. Now, turn On the device and then press F8 key repeatedly when the first logo screen comes up.
4. In the "Windows Advanced Startup" menu, go to "Safe Mode" and then press the "ENTER" key.
5. Unplug the unit and let the computer run on battery until it shuts down.
