I came down to my car last night to find that the battery was too low to start my car. It's an Opus 90, and the motherboard is an Epia M10000.

The Opus has been starting the computer fine, but I notice that it hasn't been putting it into standby succesfully. I'd come back to find the computer off and the Opus flashing 4x (which, according to the manual, means that there was an ACPI failure).

Has anyone seen this before?

Stanby will still use a fair amount of juice. How long did it sit in standby?

It is likely that one of your drivers (touch screen, sound, graphics) is preventing the computer from being put into standby. You should try to put it in standby manually (start->shutdown->standby) to what it is. If the computer is left running it will consume battery BUT the opus should still shut the power off when the battery voltage drops.

Yep, something is stopping it from going into Standby. Probably touchscreen drivers more than anything else.

The Opus does have a low battery cutoff, but I have found on a couple of occasions, that it is too low to be able to still start the car. You have to remember that these are designed for Police etc use (and that is the main buyer of them), where it is more important for their PC to run than the car to run!!

I had the exact same problem. Here is what i did. Go to the BIOS and in the power settings change to S1. I am using the M10000 Epia. This worked for me.

Could you put a resistor in the ACC line to the Opus? That way the Opus would shut down earlier.

Yup, had this problem early on with standby, came down one morning to a battery that was around 4.5 volts after recenty setting the PC to do Standby instead of Hibernate. I discovered that the Opus low voltage shutdown was not working. Called Kris, went over the situation, he called me back a week later and told me he found the bug in the code and that I should send my unit back for re-programming. This was a few months back.

The problem only occurs when the user tells the computer to shutdown or standby. If you leave the computer alone, the Opus will shut the PC down fine after the set timeout. I disabled standby after that so I don't know what happens when the PC is set to standby.

Call Kris.
