So, one morning I woke up to a section of my keyboard keys not functioning no more. Most of them are of the middle alphabet row and also the enter key. Just puzzled as to why the sudden malfunction of the keys over the course of a single night. I've tried reinstalling the PS/2 drivers for it to no avail. Need suggestions as how to move on from this. I've been considering getting a new keyboard for it (the stand-alone one and not the one on the keyboard). Either that or send the whole laptop to the repair shop and hope for the best. Need opinions.
