M3-ATX Losing Power when Lilliput "Power On" Button Pressed
I posted this in the Newbie forum, but it didn't seem to be getting much attention, I hope someone in here can help spread some light on the issue I'm having.
I have an M3-ATX PSU powering my Intel D525MW board / atom processor. 4g RAM / 120g laptop hdd. As far as powered USB items, I have the Car2PC module, an iBlue GM-2 GPS, a bluetooth dongle, a wireless network adaptor, and the touch screen input for my Lilliput 629GL monitor. I soldered the DC power cord that came with the monitor into the power / ground connections on a molex connector and connected that to the molex connector on the M3-ATX.
The system does come up all together from a cold boot. It can also be rebooted after it's come up and everything will power on. The problem I'm experiencing happens when I resume from hibernation. Here's a step by step of what happens:
- I turn the ignition key and after a few seconds I see the red light on the lilliput monitor come on signaling that it is indeed receiving power.
- About 25 seconds later music will start playing (the song continuing from when I last shut off the car), yet the screen remains dark with the red indicator light on the Lilliput lit.
- If I press the power button on the Lilliput, the system immediately shuts off. If I continue to press it, I will get a series of "No VGA Input" messages on the screen, and it will power off, but after about 30 seconds, the Intel POST screen shows up, and the system spits out the typical "The System Did Not Shut Down Properly... Safe Mode or Start Windows Normally.. blah blah"
- I assume when the system goes into hibernation after I turn the key to OFF, it does so properly, because it will resume with the music playing that was on when I shut the car off. I don't understand why the Lilliput is shutting down the whole system the way I described.
Anyone with any idea why this might be happening, I'd really appreciate it. My assumption is that the system can handle the load, as it does it from cold boots, but has issues after resume. Is this a bug in the M3?
If there's more information I can provide, I'd be happy to, I just need to know exactly what is needed, and how to get it as I'm entirely new to electronics.. as in... I bought a multimeter for this project but it's still in the packaging. I'm not afraid of learning anything or getting my hands dirty, as I've already gotten this far, I'd just appreciate a little guidance. Thank you.
