  • EPIA does not boot - Only fans come on

    Did a search on this, found a reference but no solutions.

    Have a problem with my carputer and I hope someone in here can help:

    My setup:
    MB: Mini ITX EPIA-V 1.0G in a Morex 3688 case
    Optical: Slim DVD drive (tray type)
    HD: 60G 7,200 RPM 2.5 inch
    RAM: 512Meg
    PS: M1-ATX
    USBs: GPS + Lilliput

    PS also feeds lilliput and a mini USB hub when in the car.

    The problem I am having is that during start-up the PC fans come on, the HD also spins, but that is it. The computer does not boot, not even the bios screen, or the beep that you hear as soon as it starts to boot. If I cut the power off and turn it back on a number of times, or hold the reset button down for a few seconds and release and repeat a few times, it will eventually boot. This happens all the time, except a few times when I was turning the PC on after a few hours of shutdown. But even that is intermittent.

    So I tested the following (without lilliput or the hub attached to PS)

    1- Checked power supply: All rails have proper power (3.0v, 4.9v, 11.8v)
    2- Checked HD: It spins. Replaced it with another and problem did not go away.
    3- Checked all power and IDE cables. They look good and connections are tight.
    4- Checked “switch on” pins on the power supply. Upon startup, the pins short out emulating momentary switch – I believe that is the way it is supposed to be.
    5- Manually shorted the “switch on” pins on the mother board. It works for shutdown but Problem still not solved for start-up.
    6- Checked RAM by removing and reinstalling - No change
    7- Replaced the PS PIC with the updated one - No change

    I think it is safe to say that the source of the problem is either the motherboard or the bios. I do have to add that when I had the original Power Supply and ITPS I never had this problem. It was also okay after I switched to M1-ATX for a little while. The problem seem to have started when I upgraded the HD from a 20G 2.5 inch to 60G 2.5 but I don’t think it is the HD because I put the old one back in and I still have the same problem. I think I have done something that is causing this. At first it was a "once in a while" thing. Now it is almost all the time.

    With the description what do you guys think? Is it the motherboard? Is it the bios? Is it the RAM? Any help would be greatly appreciated.

    Hey dude..

    Have you tried the setup inside with a normal PSU ?

    I will do that, and remove the IDE cables, power from HD, CD/DVD or whatever you have attached to the motherboard.

      This may be a bit obvious, but you didnt by any chance forget to connect the CPU power lead?? Its a very easy mistake to make.

      Baring that, I had a similar problem with my desktop recently and it turned out to be a faulty motherboard.


      edit:

      just re-read the o/p. its probably not the cpu power lead if it boots sometimes. Try clearing the CMOS in case there is something set funny there. You could try re-seating your cpu, but I suspect this is unlikely to have any effect (I have been known to be wrong though)

        I see this problem all the time with normal desktop PC's....its most likely a grounding issue. Try assembling the PC outside of the case, ontop of the motherboard box, and see if it boots then. If so, then place some foam under the mobo (Cut to fit) and then screw it in.

          I will do what you suggested and see if that helps but I had not touched the motherboard at all. I did replace the PSU (from 60W Morex to 90W M1-ATX)inside the case though. Do you think that there maybe a grounding issue through the PSU as well? Come to think of it, I also drilled a couple of small holes to mount my mini USB hub on the outside of the case. I was very careful not to let any metal shavings get on the board but now I am not sure. If it did, would that cause these symptoms too?

            Quite possibly, check for metal shavings, also try the old PSU again.

              Ya make sure no, i mean NONE of the metal soldering leads or metal parts from the PCB's of both thte PSU and the Mobo are hitting metal. Also make sure the USB mod you did has no exposed wires or metal parts either, this could very well be it. When you hack something up or change out parts make sure theyre insulated and seated correctly.

                Also had same problem a while back. Problem was that not enough power (Watts not volts) was getting to mobo in order to boot. Espcially when going from 20GB lap top to 60GB -power consumption increases significantly. An external 20GB laptop HDD can boot from USB power whilst a 60GB cannot and needs external power.

                Once more watts was upplied she booted like new

                Hope this helps

                  I think pdhbo is on the right track.

                  I had a very similar problem when I first got my machine. I too have a M1000 mobo and a M1-ATX power supply.

                  The problem was due to the power source. We were using a AC-DC variable power supply which we set to 12V. At first I got the same problem you did. Then I noticed that the current setting for the power source was set very low(500ma). When we increased it to the maximum(3A) and turned the PC on, it booted up. However, it would shutdown if the system ever tried to consume more current than that, which was often. Even loading a CD would cause it to consume more than 3A and this resulted in the system rebooting. Eventually, we hooked up two power sources in parallel to increase the current output.

                  In summary, make sure your power source can provide enough current ( minimum 3A. recommended at least 5A). This means that power source must be able to provide at least 60W ( 12V * 5A = 60W). If you are hooking up the mobo in your home(which im assuming you are), and need an AC adapter, check used computer or electronics stores for one that outputs 12V and has a high current rating. Many laptop ones provide this much current where as household ones for things like cell phones , have very low current outputs and won't work well for a mini PC. Either way the current rating or at least the power rating, should be shown on the adapter itself.

                    Afterall, its hard to find connector on EPIA-V, he he.

                      Okay. I give up! I disassembled my carputer yesterday. Insulated anything that I though might give me grounding problems and put it back together. I also rewired it with better and cleaner wires. Hooked it up to the 60 watt brick and it booted right up. Was very happy! So I put it through several back to back shutdown and startups and it worked everytime. Then left it on for a couple of hours to download some music from my server. Shut it down to take it to the car but remembered that I had forgotten one song so I tried to boot it back up....but it did not work this time. It was just like before, lights and fan came on but it did not boot. Left it off for a couple of hours, tried again, and it booted right up!

                      Looks like the PC does not want to boot up properly right after it has been on for a few hours and is warm. When it cools down, it has no problems. And I don't think it is the actual heat that is affecting it because I put it in my car, parked under the sun and the carputer box really got hot but had no problems booting. Then after it ran for a while, it did not want to boot again until it was off for a while.

                        Did u try another PSU? It was suggested 2 times here, did you do it?
                        Time displayed in a different way!

                          Just curious, does it ever give you any problems booting up when you hook it up to your vehicle or just in the house?

                            Are us using morex 230V to 12V converter with M1 PSU?
                            I got exacly the same problem as you. I houd out that Morex AC-Dc converter doeas not give inuff Power. So when I striped my Epia for all extra tuff it works fine, but when I put mye USB kayborad, tuchscree, mouse, bluetooth, TV card. The epia won't boot.

                              Malebuffy,
                              I don't have another PSU but I am getting one this weekend to try with. I too think that this maybe power supply issue but a few in the other forum with similar problem have solved it by updating the bios. I am afraid of touching the bios as I may kill the board while doing that. So I will try the PSU first and if it does not work, I will update the bios.

                              Cocoman,
                              The problem is happens it both places but is more evident in the car as I use it more often there.

                              Goose,
                              Yes, at home I use the Morex brick and in the car is connected directly to the battery.

                              The thing that gets me is the carputer always boots just fine when it has been off for a few hours while at work or over night. But if I turn it off for a short time, say one hour, and try it back on, it will not boot. Then I have to push the restart button a few times then it boots. Has no problem if I restart but if I turn it off it may not boot again on its own.
