Dear Annie,

Please check whether there is no dust blocking it and restricting

it to work properly and also check whether there is no virus

infection causing the problem.

Thanks in advance.

hi,I have been having the same problems where only a few number keys were not working at all..I tried fn + f`11 and it became fine for some days then again same problem.
I took a fresh clean postit paper(stickon) and folded the paper to give it smooth surface at the edges, cleaned the keypads slowly..specially the area of number keys..put it slightly inside the no.keys n it started working..i think the dirts got accumulated there..u can try this only if ur on screen keyboard is working...then thz no software problem..let me know if it worked or not..
good luck!
