CarPC starts up with ignition off when I exit my truck
I installed my CarPC about a week ago in my 2002 Dodge RAM 1500 front center console. Everything works great. It starts up when the ignition is turned on and shuts down when the ignition is off.
I've driven it for about three days now with no problems until today. I went out to the hardware store to get some parts to mount the LCD screen. I watched it shutdown when I left but it was back on when I got back about 30 minutes later.
When I got home I watched it shut down when I turned off the key. I sat there for about 2 minutes and it stayed off. As soon as I exited the truck I heard "BEEP" and it started back up.
I can reproduce over and over again. I even sat there for 10 minutes with it off and the same thing happened when I exited.
It has to be static electricity. It got very cold here over night and the static is terrible. If I get out very slowly, it doesn't happen.
I unplugged all the peripherals and even unplugged the ign/acc lead and left the 12V and Ground the only things connected and it still does it.
The 12V line is a 12 gauge wire coming directly from the battery. The Ground is bolted to the chassis under the dash. The ign/acc lead doesn't matter since it doesn't have to be attached for the problem to occur.
The power supply is an M2-ATX. I even tried another M2-ATX and it does the same thing.
If I put my multimeter on the acc/ign lead when the truck is off I get 0 volts but When I exit it jumps up several volts for a fraction of a second so it's somehow related to static.
Has anyone else had this happen? Any ideas what I can do to stop it?
