restore from standby

[aartjan]

I have a peculiar problem: one of my laptops is doing standalone measurements and may loose AC power. The laptop may have to survive up to 100 hours, and obviously, this can not be acomplished on one battery charge. Therefore I made a pretty nifty tool (with LV) that monitors whether AC is present and switch to a survival mode when it runs on battery. This means I basically set it to standby most of the time. Periodically, I revive from standby to detect if AC is present again. I revive from standby using Windows task scheduler.
And that is the problem: taskscheduler doesn't get the computer out of standby when it was put into standby with my method. And windows built-in power management is not doing the trick quite right either.

Does anyone know how to use labview or windows script to get a computer out of standby?

Thanks!

Karsten,
Thanks, that was the kind of document I was looking for, short of VI's already made to interface with win32.
As far as the project it was intended for, I resorted to a small micro-ATX computer instead. The computer has the necesary BIOS feature "power on after power failure." It senses that power is supplied again and boots. I hope to continue my work on this, though, because it adds great functionality to "in field" laptops.
