Thanks Richard, What I'm looking for is a way for the protected computer to detect when the power fails ( and (or) when the alternate power source has kicked on) and page me, or somehow let me know that something has gone wrong. I can't be the first person to think of this so there should be some way to do this right? I've been looking for a way, but I haven't had any luck yet. --- On Sun, 8/16/09, Richard Howells <[email protected]> wrote: From: Richard Howells <[email protected]> Subject: RE: [OT] detecting UPS activation To: [email protected] Date: Sunday, August 16, 2009, 9:21 AM AIUI a UPS usually has a serial (or USB) line that you connect to the protected computer. The proprietary software that comes with the UPS then arranges for an orderly shutdown when the UPS battery is getting weak. So I guess you need to talk to your UPS vendor. I think the whole point of a UPS is for the protected equipment to carry on business-as-usual. So (excluding the proprietary software) I’d EXPECT the protected computer to be completely unaware.

Such as when the power fails and the battery or backup generator kicks in. I've tried using the GetSystemPowerStatus( ) to detect when the ACLineStatus changes but when I unplug my battery backup from the wall and have the machine running from the battery those functions report that the system is still running on AC. What I need is an event handler or function that will fire as soon as the power source for the machine changes. I've also tried using the WM_POWERBROADCAST event message to flag when the power source changes but that didn't work either. I'm looking for something written in C++ that I can incorporate into my project. Any ideas? In the mean time, I'll keep looking. Thanks guys. -Eric
