Default Why does a keyboard need to go to sleep.

Online I see for sale a wireless keyboard/mouse, and it says about it

"Auto Sleep And Wake Feature

This keyboard also features an auto sleep and auto wake mode. If there
is a long period of inactivity, the keyboard will automatically go into
a sleep mode. To exit sleep mode, press any key."

Why does it have any need to go to sleep. Why would it use any power
if no one is pressing a key?


Sleep IS not using "much" power.


So since the keyboard isn't using much power except when someone is
pushing a button, it's always asleep the rest of the time, is that
right?

The only difference is that the
first keystroke may take a fraction of a second to switch the clock
and get everything running again.


A remote control needs a clock?

Don't worry about it. It's doing what you want.


What are you, a 1950's doctor?

This is not a cordless phone that waits
for phone calls, whose battery drains even when not in use.

(For that matter. why don't cordless phones have on/off switches. They
can go without charging for about 2 days. If you could rely on the
ringer in the other room and turn the cordless phone OFF, they wouldnt'
need a charge for 10 days or more. )


My cordless phones do go 10 days or more.
I have two phones and one charger. I just swap them every couple of
weeks.


Do they have on-off switches. If they go two weeks without one, they'd
10 weeks with one.

This is the item. Before you buy it, there's a newer version now.
