It Happened Twice!!!!

**DJKhan85** · 06-25-2004, 01:26 PM

I have an opus on my computer. Now I need to make a switch of some sort to completely cut power off to the computer after hibernation. I've had to charge my battery up twice thanks to my computer. before I charged it the second time I check my battery voltage and it was at 4 volts. I thought the opus was supposed to monitor the batteries voltage and shut it self off? SO now that I am at my wits end I would like to know how to create my own shut off switch. ANY HELP WILL BE GREATLY APPRECIATED!!!11!1!!

Maybe it's an old battery and it can't hold a good charge for a long period of time...

wow a new altima and on the third battery already?
What I have is my opus 90w powered with a relay inline. This way the carputer can only be turned on and off with the key. Yes it won't auto shut-down.

What you can do is the same thing and the carputer will continue to autostart. But shutown you have to figure out. I don't even worry about it because half the time I cut the power to windows xp (no problemo).

I thought an Opus 90w could shut off all the power after closing Windows?

It can. Take jumper JU1 off. I think some people said the Opus didn't shut down when the pc drained their battery, but I bet you they didn't change the jumper setting. With the jumper on and in stand-by there can be a drain up to 8 watts.

Thanks for all the quick responses
so I just take out all the jumpers correct?
SO that it has a 10 sec shut off delay. I thought this was the factory default so I didn't bother to check this upon installation. Looks like I gotta take everything out again.

Only the 90W Opus has this jumper. The 150W Opus ALWAYS supplies power on the +5V Standby rail. I used a relay to avoid this problem.

Can you perhaps elaborate on this method? It seems as If this is what I have to do as well.

Better yet, set the 20 minute delay and power down/hibernate through your interface or a short cut. That way you can keep the pc running if you fill up for gas or just getting some groceries.
