Comment 26 for bug 215035

i think the difference might come from the fact i have the corded variant of wave keyboard. anyway, on my keyboard fn-f10 and fn-f11 are almost the same - both have a magnifying glass, and f10 has "www" wrtiten under it, while f11 has "pc".
still, i can see that some keyboards do have a battery there (just by looking at the picture here:

do you have any idea what it is supposed to do (or a windows w/ setpoint to actually check it)?
