Hello, My Surface Pro 3's battery gets drained even while it's connected to power and charging. It wasn't like this before, I'm not sure but it looks like this started happening after I had upgraded to Windows10. Power supply is working normal, the device recharges successfully. But even if it's 100% charged and the power supply is connected, it uses some battery power and drains the battery if I use heavy apps like games. Can't we make it use the power supply only ? May it be related to some power management scheme or settings ?
