That notebook is secured by screws and plastic clips. Check to see if the screw on that corner is loose or lost, tighten if loose but take care not to over tighten and potentially strip the plastic thread, press the corner down so it clicks into place first. If it is missing look for a replacement screw online or in your junk drawer, local retailers, etc. DO NOT replace it with a screw that is too long or threaded differently. Take the one from the other corner with you in your search to compare.
