Opus stays on in standby

**camarossguy2** · 10-02-2004, 07:52 AM

I was under the impression from reading on here before i bought my opus that i could have The system go to standby instead on shutting down, thus speeding up the off/on times and saving what i was doing.

So now i have my carputer with and opus 150w, and i set the "when i push the power button" to "standby"

Well the puter goes to standby, BUT the opus stays on??? I cant turn the computer back on unless i unplug the opus either.

Works fine in shutdown mode; the computer shuts down normally and the opus turns off as well. when i turn the key back on it all powers back up fine.

How do i get the opus to shut off like my desktop PC would if i put it in standby?? is there anyway?

no results in my

Standby keeps the memory alive, which means the PSU has to stay on to provide power. Therefore, the MB doesn't send the shutdown signal to the PSU. If the opus was turned off, you'll lose your standby state.

What you probably want is hibernation, which writes the memory state out to disk and therefore can shut down completely.

????????????????????????????????????????????

I have always thought standby is the one where it writes the RAM to the HD??
brb, lemme check it out on my puter

Ok:

On my desktop in my room, I set the computer up so when i push the power button, the computer goes to standby.

I pushed the button, and the computer blue windows screen apperas and "windows i preparing to standby"
Then the computer AND the POWERSuply shut down.
Push the button againa nd in 5 secs the computer is back on.

When i set it to hibernate when i puch the power button, I push the button and the computer goes to a black windows screen and says..."windows is preparing to hibernate" then both windows AND the PS shutdown as well. Push the button again and the computer posts, then shows "windows is resuming"

So again why does the opus not shut down like the PS in my home PC?

I guess i will just have to hibernate instead on standby.

Your desktop PSU might be capable of going into standby mode, where is produces the required (low) power without requiring active cooling, and so turns the fan off which makes it seem lke it's completely shut off. On the other hand, I know all PSU's keep a small 5V current alive even when 'off', so maybe that's enough for the MB to refresh memory, although that doesn't seem to be the case with the opus.

In any case, standby -> memory on, hibernate -> memory off; hibernate will take longer to restore, but it won't put a drain on your car battery.

Read the manual - it tells you to get your Car PC working correctly (standby on/off via power button) on a normal ATX power supply FIRST then add the Opus.

A car alarm puts a little drain on your battery too - except with the Opus it monitors your battery to prevent damage. If you've spent the money on an Opus use as intended and have a 2-4 second switch on rather than a long long resume from hibernation

I ALWAYS leave mine on standby and have done since march and my battery's fine

If you don't believe it, try to unplug your homeputer when in standby. It will post and boot windows from zero when you put it back on...

Standby in ATX standard is always on. Look in you desktop computer when it's off and you'll see the LED is on (if it has an LED).

First of all, what type of motherboard are you using? I asked this question because of 1 reason. I do standby on 2 boards b4, and one works very well and the other... .... well, I'll still have to contact OPUS for that, but I'm too lazy to do so.

First board. M10k -> Standby, works flawlessly.

Second board. Insight P4-ITX -> Standby, works, but power still stays alive... PSU fan still runs, so does CPU fan. Have to wait till the OPUS failsafe to kick in to restart the PC.

So, again, what board do you have?
