Re: UPS shutdown procedure

Also if your UPS doesnt have the capacity to cope with the pwr used by your
PC it will shut down immediately ie no proper / gracefull shutdown

I have a UPS attached to my PC but actually haven't got round to testing
it, as of yet. The purpose, as I understand it, of the UPS is to provide
a
battery backup should the power supply be interrupted. The battery will
last from 10 minutes upwards depending upon the make, and obviously
price,
of the UPS you purchased. When the power is interrupted the UPS kicks in
to
keep your system running long enough for you to manually save files and
close down (that's how I understand its function). If, during this time,
you do nothing the battery power drains and your PC gets abruptly turned
off in the same way it would if you simply tripped the switch on the
power
plug.

As far as I am aware, and someone will correct me if I'm wrong, I am not
aware of a UPS that will automatically shut your pc down for you when
the
power interrupts or battery power is low, so when you ask 'is this
normal'
I would have to say, yes I is.

Hello all,

I just tested the shutdown procedure for an APC RS900 power supply,
the driver for which was automatically installed when I plugged it
into the USB port. I set it to shut down at 10% remaining power, and
watched it run down as a test.

When it shut down at 10%, the machine basically when blank and turned
off immediately, rather than going through the usual windows logoff
and shutdown procedure. Is this normal?

Thanks

Ok, I just plugged it in and Windows installed a little PnP power app
in the system settings folder. I will try the installation disk
next... I'll update what I find.

Thanks all for the advice

Dean
