I have laptop Dell Inspiron 1545 Windows XP. l cleaned it by wet hanky. Now when I press (q) = it writes (q1), when I press (w) = it writes (w2)
When I press (e) =it write(e3).....the same for (r,u,i,o.p) and the remaining letters don't write anything.
I try the solutions like.....(as I dont have num key in my laptop)
fn+f11/ fn+f12 / fn+prntScr / press both shift on the same time
also I make num lk off by using on screen keyboard
According to some discussions, the keyboard might be faulty or there might be some dust.
You should try to disconnect / reconnect the keyboard :

If you still have the problem, you can try with a USB keyboard to know if it's hardware related.
if l replace the keyboard by a new one ,the problem will disappear?
It might very likely. At least you should try with an external USB keyboard.
