Let us know if you do not understand any of our advise or the tutorials. We want to save you from an impending disaster. As said, you could get lucky and the drive last for a couple of more weeks, but maybe not.

Your computer will also run cooler if you choose the power saver option.
WIN key + X | in the section that shows your battery, choose Power Saver.
As soon as possible make that backup or at least save of to usb sticks all your important data, pics, music, anything dear to your heart.
