Can't wakeup

[Anonymous user]

Hi all,

I'm using "Back-UPS Pro 550" and I have following problem.

When I set BIOS option on my PC to power up always, when there is power to it, my computer needs at least 10 seconds with power-off, to be able to start again.

In general everything works ok, PowerChute, shutdown PC as expected, UPS is restarted after ~1:40 after PC....

BUT, if main power is down, and up, between computer shutdown and UPS shutdown, computer does not start.

This is because UPS restart procedure (and thus power off to PC) only takes 1-2 seconds or something, not nearly enough for computer to start (> 10 seconds).

Is there any way to work around this problem?

Greetings,

Filip

Filop,

Please see forum post auto start of loads not working properly.

10x for reply 🙂

Interesting stuff is that if main power is cut from PC without proper shutdown, PC needs no such delay...it starts even if power is interrupted for just 1 second (or so).

I'm wondering if this can be configured somehow in windows....I've tried many shutdown options but none of them works.

ok, problem solved 🙂

You can instruct windows not to cut off power to computer on shutdown using group policy editor (gpedit).

This may not be installed on all versions of windows, but you may download it (google for it).

Start it and go to "Computer Configuration/Administrative Templates/System" on right panel find and enable option "Do not turn off system power after Windows system shutdown has occured.".

In this case, computer powers up in any power outages 🙂
