macbook keyboard issues

hi there,

i'm having some troubles with my macbook keyboard and i don't know what can i do to see where's the problem. strangely, i only have this problem when i work with battery or battery+electricity. so, i have a regular keyboard when i use my macbook without battery.

but enough talking. problem is:

some keys from my keyboard don't work when i'm running on battery or battery+electricity. they are, for example: caps lock, space, backspace and other peripherical ones. other work perfectly as enter, letters and numbers and the f's.

any idea?

thanks in advance.

 

nope, it's already over. i'm using macbook with electricity all the time and it works just fine, but well, this should work without it.

thanks for reply.
