After several years of service the unit beeped, unnoticed by the user
until
it shut down her computer. Got a new one for her, but thought I could
use the old
one on my TV, since it was probably only the battery. Yes, I know, I'm
a cheapskate!
But the battery didn't bring it back. The power LED doesn't light up,
and there is no power
to the battery-supplied recepticals after being plugged for 24 hours.

I have no user's manual. There are two external buttons, one on the
end that is easily pushed
since it projects up to the surface. The other is a little tiny button
way down in a hole.
I've pressed both with no effect.

What am I missing?

TIA
