Re: [Apcupsd-users] APCUPSD: Windows Task Scheduler Stop on Switch to Battery Power

I thought it is exactly the idea behind it. It is not there to emulate 
anything, it gives you manual (=much greater) control over things and 
everything you do, you do through scripts.

Předmět: [Apcupsd-users] APCUPSD: Windows Task Scheduler Stop on Switch to 
Battery Power
" 
Hello - I am new to APC UPS and APCUPSD!




I have an APC BR1500GI (Backup Pro) device, connected via USB to a PC 
running Windows 10 x64. All configured, tested and working fine. I also have
slave W10x64 devices powered from the same UPS and talking correctly to the 
Master APCUPSD. So everything working fine!




The issue I need help with is getting the Windows Task Scheduler to react to
'running on batteries' with the apcusbd battery device driver. 





The PCs are running CPU intensive tasks triggered by the Windows Task 
Scheduler. Each task monitors a directory and processes a workload when a 
new file is detected - they fire repeatedly looking for work. If the UPS 
switches to battery, I want all running tasks to end immediately until mains
power returns.




The task power options are correctly set on the tasks - 'Start the task only
if the computer is on AC power' and 'Stop if the computer switches to 
battery power'.




If I plug in the APC UPS and let the standard Windows drivers load, the Task
Scheduler behaves as expected.




When I install APCUPSD and the battery driver is replaced with the "American
Power Conversion USB UPS (Apcupsd)" driver (v1.0.0.1 Jemej Simoncic 19 Jan 
2015), Windows Task Scheduler no longer detects this switch to battery 
power. 





Everything is working as expected with APCUPSD - the APC tray icon changes, 
the correct events are detected etc. It seems that this driver does not 
fully emulate the 'battery' role to the OS - or have I missed a 
configuration option?




I could develop a workaround using scripts triggered via apccontrol, but 
this would required something like powershell to 'end' and 'disable' named 
tasks and to reenable them.




>From my internet search, I have not found a method to signal 'on battery' to
the Windows OS - this seems to have to come from ACPI/BIOS? As such there 
does not seem to be a way to manually set the power mode from a script.





Is there a configuration option I have missed, or a more obvious solution? 
Or is this an enhancement?




APCUPSD does exactly what I want from a Master/Slave and Device Management 
perspective - Thank You to the developers - and documentation writers!



Your guidance appreciated

Pete
