Regardless of which Windows system you are running, apcupsd logs most error messages to

c:\apcupsd\etc\apcupsd\apcupsd.events. This type error messages such as configuration file not

found, etc are written to this file. Note that on some systems (WinXP, possibly others) Apcupsd is unable

to write to this file when running as a service.

Email Notification of Events

It is possible to receive email notification of apcupsd events using some simple Visual Basic scripts

contributed by Ed Dondlinger <[email protected]>. The scripts are automatically installed in

the etc/apcupsd directory of your apcupsd installation but are disabled by default. To enable them, first

open them in a text editor such as Notepad and edit the USER VARIABLES section to set your email

preferences including address, server information, etc. Then rename the script files without the

*.example suffix. Scripts are supplied for onbattery, offbattery, and commfailure events. You can copy

the scripts to other filenames and modify the email body text to respond to other events as described in

Customizing Event Handling.

Killpower under Windows

If your batteries become exhausted during a power failure and you want your machine to automatically

reboot when the power comes back, it is useful to implement the killpower feature of the UPS where

apcupsd sends the UPS the command to shut off the power. In doing so, the power will be cut to your PC

and if your BIOS is properly setup, the machine will automatically reboot when the power comes back.

This is important for servers.

This feature is implemented on Unix systems by first requesting a system shutdown. As a part of the

shutdown, apcupsd is terminated by the system, but the shutdown process executes a script where

apcupsd is recalled after the disks are synced and the machine is idle. Apcupsd then requests the UPS to

shut off the power (killpower).

Unfortunately on Windows, there is no such shutdown script that we are aware of and no way for apcupsd

to get control after the machine is idled. If this feature is important to you, it is possible to do it by telling

apcupsd to immediately issue the killpower command after issuing the shutdown request. The danger in

doing so is that if the machine is not sufficiently idled when the killpower takes place, the disks will need to

be rescanned (and there is a possibility of lost data however small). Generally, UPSes have a shutdown

grace period which gives sufficient time for the OS to shutdown before the power is cut.

To implement this feature, you need to add the -p option to the apcupsd command line that is executed

by the system. Currently the procedure is manual. You do so by editing the registry and changing the line:

c:\apcupsd\apcupsd.exe /service

found under the key:

HKEY_LOCAL_MACHINE Software\Microsoft\Windows\CurrentVersion\RunServices

c:\apcupsd\apcupsd.exe /service -p

If you have a Smart UPS, you can configure the kill power grace period, and you might want to set it to 3

minutes. If you have a dumb UPS, there is no grace period and you should not use this procedure. If you

have a Back-UPS CS or ES, these UPSes generally have a fixed grace period of 2 minutes, which is

probably sufficient.

Power Down During Shutdown

Our philosophy is to shutdown a computer but not to power it down itself (as opposed to having the UPS

cut the power as described above). That is we prefer to idle a computer but leave it running. This has the
