Here's my findings about my setup I've been having issues with...
SETUP:
Casetronics DC-DC board and external PSU
EPIA-M 9000
IBM Laptop Travelstar 4700 RPM 40Gig HD
Pioneer 16x slot load DVD
256 PC2100 RAM
Fellows serial internet touchpad
Creative serial IR reciever
Griffin USB Powermate
M-Audio Sonica (USB sound device)
300W inverter wired to the battery
When I was setting up the carputer in my house I had no issues AT ALL for days. After the install into my car I started having issues, after about a week, with the carputer shutting off instantly when I would use the DVD after the carputer was on for about an hour. I added a 40mm fan to the southbridge because I thought the heatsink was getting too hot. A few days later it started shutting off after about 5 min. of DVD use when it was just booted up. A few days after that it started shutting off with just WinAMP playing for about 15 Min. Then it just wouldn't start at all. I would get an "electrical click" through the speakers but nothing would would spin up, not even the fans. The computer was not even warm during this time.
I was reading your other posts about the power light flickering when you would have the same thing happen to you but I never got the flickering light, it just stayed solid and as bright as when it was powered up normally. Anyway, this morning I took my center console apart (the carputer is installed in the arm rest) and disconnected EVERY DEVICE except for the HD and DVD drive. IT STILL WOULD NOT BOOT UP. I checked all the wiring and looked at the DC board for any burn marks. Nothing...I unplugged the two wire "bridge" from the DC board and plugged it back in. WHOULD YOU BELIEVE THE FLIPPIN' THING BOOTED AFTER THAT!!!
I did put a DVD in the drive and it had no problems playing it for a few minutes. I did not get a chance to test it extensively but I will on my way home tonight. I will post my findings then.
I'm not sure if it's the external PSU not being powerfull enough or something else. I did notice at CompUSA they had
THIS Targus Auto power adaptor, that supplies 70W and it's about half the size of the PSU for the DC board, on sale for $75. I need to do some serious testing soon to get this BS finalized.
