how to get my Acer laptop to type letters and not numbers

Hold in the Fn (function) button, usually in the lower left, and push the NumLk key (usually F11 on Acers, I believe). If you need more help give me a model number and I can be more specific.
 


OH MY GAWD..... I LOVE YOU... I HAD GIVEN UP ALL HOPE FOR MY Acer keyboard... when i saw this... in 2 seconds (2 keys -fn and numlk) it was solved... i love you i love you i love you
