Task To Wake The PC?


P

(PeteCresswell)

Right now, I am using a BIOS setting to automagically turn the PC
on every morning at 0630.

I have a "Sleep" .BAT file scheduled to run every night at 1 in
the morning. (psshutdown.exe -d -t 00)

I notice that in Scheduled Tasks | [task name] | Properties |
Settings, there is an option called "Wake the computer to run
this task".

Seems like maybe I could create a .BAT file or something that
basically doesn't do anything - maybe a "Time" or "Date"
command... and schedule that for 0630 and have the PC come out
of Sleep mode based on that instead of the BIOS option.

More attractive bco the increased options in XP's scheduler.

Or am I just wishing?

What's wrong with your existing scheme ?

The problem most people have with getting the scheduler to do
it, is permissions and accounts used to run the script at
the appointed time. That'll be your roadblock to quick success.

If it was me, I'd just leave it alone. I'd only change the
setup, if I needed the BIOS feature for some other reason.

In the hardware, the RTC (real time clock) may have only one
comparison register for the wakeup function. If you use the
Windows scheduler, then Windows owns the timer. If you turn
on the timer feature in the BIOS, then Windows may lose usage
of it (in Sleep Mode). So if you do want to test this in Windows,
I'd recommend doing something to turn off the function you're
using in the BIOS first.

It's possible some other chipset, has multiple registers for
that, so both can function. But I've read in the past, of
cases where there is only one hardware facility, and either
Windows or the BIOS has to "own" it, for it to work. When
Windows owns it, Windows gets to determine the register
value, and then the BIOS doesn't load it's appointed value
just before the power goes off.
