The clock on my range has never kept correct time, yet it keeps running and
using electricity. (Small amount, but many little things like this can add
So I pulled my electric range out from the wall, unplugged it, and
disconnected the clock. (Only do this if you know what you are doing.)
I already have many electronic things on power strips and turn off the power
strips when not in use. These things use electricity all the time...
Watches are pretty much out of vogue as most people check their cell
phones fro time. It looks like you'll have to buy her a new cellphone
for kitchen work.
Electric consumption of any clock, sans lighting, is nearly
negligible. Certainly compared to a ranges power use!
Just don't turn off a power strip that has a desktop computer plugged
into it. The power supply provides +5V Standby to the motherboard's RTC
(real time clock) and CMOS RAM (which holds configuration data). When
the computer is unplugged (or during a power failure) the small,
non-rechargeable, lithium coin cell battery, maintains the RTC and CMOS
RAM. Often these are soldered in, not in a battery holder, and difficult
to replace. These batteries are not intended to supply power to the RTC
and CMOS RAM for long periods of time (unlike computers of 15 years ago
where the power supply didn't provide any power when the system was
turned off, and they used a much higher capacity battery).
My computer has an Asus A7N8X-E "deluxe" motherboard for the AMD "Athlon
XP" processor. That is maybe 5 years old. I got it the same day I got a
"3200+" processor. The battery is removable and replaceable. I have that
computer on a power strip that I often turn off.

Similar story here: I have a Tyan Trinity 400 MB w/Pentium, about 8
years old, that I turn off & on daily. It has never lost CMOS data, not
once. (And yes, it has the newfangled type of on-off switch, ACPI, all
that type crap.)
The best argument against democracy is a five-minute
conversation with the average voter.
Asus is a top of the line motherboard, so you'd expect them to have a
replaceable battery. The boards sold for use in name brand computers are
decontented to save ever penny possible, literally (I used to work for a
very large Taiwanese motherboard company's U.S. office). This includes
using a very low capacity back-up battery, and soldering it in.
Remember the large rectangular Tadiran batteries with a wire and a
connector used on old AT motherboards? They used these because the
battery had to power the RTC and CMOS for long periods of time because
when the power was off there was no +5V to power the RTC. The ATX supply
changed all this. There were other reasons as well. With the ATX supply,
there is power to the PCI slots so you can do remote power-up through
the network (though with most boards these days the Ethernet chip is on
the board, and can be powered directly with standby power).
There's very few motherboards from anyone that dont have a replaceable battery
None of those have soldered in batterys now.
But dont have a clue about whats happened since then.
Bet you cant list even a single example of one of those with current
Nope, they didnt use coin cells because they couldnt
provide enough capacity for the older RTC and CMOS.
Wrong again. The real change was the current used by the RTC
and use of flashram that takes no battery current for the settings.
ALL modern motherboards get YEARS out of the replaceable battery
even if you unplug the system from the mains when you arent using it.
And it costs peanuts to replace when that is necessary too.
How odd that that wasnt eliminated in the cost cutting too.
You've never had a clue about the basics, which is
presumably why you got the bums rush from that importer.
Back in 8088 days, motherboards often had a rechargeable battery
soldered in. Solid state circuitry was not as efficient back then, and
a motherboard clock would quickly discharge an alkaline or silver button
Slightly earlier than that, there were no motherboard clocks. If you
wanted a system clock, it was on an expansion card.

He didnt say that the power strip itself uses any power, just that he uses
power strips as a convenient way to turn off what isnt used all the time,
most obviously plug packs/wall warts that so many of the smaller devices
use now, and other stuff that isnt normally turned off when not in use.
It's sort of hard to believe that it wasn't keeping correct time. Was
there perhaps a "cook timer" function operated by a little knob in the
center of the clock face? That's where the one on our stove's clock is,
and if you don't do the cook timer setting function correctly you can
advance the time on the clock.
Plus, you can't set the clock "backwards", so if you advance it say 10
minutes by clumsy setting of the cook timer the only way to reset the
time is to crank the minute hand around almost twelve rotations,
someting SWMBO never sees a need to do.
Some power strips do use power. To light up the little pilot lamp which
indicates that the strip's switch is on.
I wonder (but am too lazy to calculate) how long that light would have
to be left on to add a penny to your electric bill. <G>
