First thing to try is putting it face down on a towel or something soft. Get some heavy books close to hand. Use a hair dryer to heat up the area well. Keep it moving around the area . Then quickly put some heavy books on top and leave for a bit it might reactivate the adhesive. Or 2 put elastic bands tightly around to hold it where it should be then heat up with a hairdryer. If those options don’t work. Then you’ll need to either replace the back panel adhesive or just replace the the entire back panel altogether as it will come with new adhesive attached.
