Thread: Decrease fake UPS stutdown time

Funny, mine hibernates immediately..

Laidback,

I got the fake UPS shutdown idea from visiting your website. I followed your instructions and can't seem to get the computer to stutdown faster.

BTW, congrats on the new addition to you family! I also am a new father, we had ours on July 26, 2004.

Some one wrote software for shorting out pins 4 & 8. Its in the software development forum, search for shutdown controler in there and you should find it. You can adjust the time with that if your using pins 4 & 8.

Thanks for the advice. I considered the small program, but selected the fake ups and design the shutdown controller around it. I don't want to rebuild the shutdown controller if I can figure out how to reduce the hibernation delay.

Thanks & congrats back to you!

There's nothing in setup telling it to wait 30 secs? What did you build?

Typical user error…

I forgot to uncheck the “Enable all notification” in the UPS Configure screen. It now hibernates immediately when the 5v drops.

Glad you got this fixed!!!
