I bought a brand new Dell Inspiron 7537 laptop in june of this year. Yesterday while i was using my laptop it shut down for no reason and when i have powered it on again, my keyboard keys were not functioning properly for example the d key was working as page up and E key as end. I have the same issue for C,L,P,6,7,4 keys but all other keys are working properly.i used a USB keyboard and it was working properly. Is there anything we can do at to fix it?
