    Angry Hibernation too slow -> m2 power off

    Hello, I have a d945gclf2 and the m2-atx psu, some days ago my board died so I replaced it with another d945gclf2, and replaced the buggy m4-atx with m2-atx, wich have been working in other carpc.

    But now, when I hibernate, it is too slow, so m2 power off before it has finish, and when I start pc, it starts xp from the begining.

    I have 1 gb. of ram, but I think this is not the problem because my other mobo worked well.

    Some idea??

    Thanks.

    Ps. I have tried minlogo but it always starts as "system" and not my user account

    Increase the time that the M2 cuts off all power by rearranging the jumpers (refer to manual)? Or speed up hibernation by decreasing the amount of ram.

    Yeah, I have thought that I should set the 1 min + 1 hour mode, or buy a 512 mb. ram, but my doubt is: Why it didn't happen with my last mobo? Could I do anything else? (I would prefer a software solution because my pc is really hidden)

    1 min + is a bit long to go into hibernation. For convenience, I personally wouldnt want to set the power timer to anything over 1 min, just so I can more easily have the M2 cut power should the system crash.

    Different motherboards will hibernate at different speeds. Maybe benchmark your hard drive (Crystal Disk Info, HD Tube) and see how fast it is? Perhaps that is your bottleneck. You can tweak your hard drive speed by enabling write caching in the device manager, or poke around the BIOS's settings. You dont need to buy a 512mb stick, if you've already got 1GB, you can just go into msconfig and set maxmem=512, that way windows will only use 512mb.

    I agree.

    But it is exactly the same model of mobo, with the same bios and the same connections...

    This is the same hard drive too, but there is a difference; when I stuck the power wire, it moved a little, maybe it has a bad connection?

    The m4-atx had a 24-pin molex, and the m2 has 20-pins; the mobo manual says it doesn't bother, but may it be a difference?

    Didn't work...

    I've tried to unplug my rcjoycon and now xp starts much faster than before (I don't know why);

    And I've seen that my mobo doesn't keep the time and date (don't know why)

    I think I'm gonna try to reinstall xp

    Any idea?

    Would it be possible that m4 had a 24-pin molex and m2 only a 20-pin molex, so it has power problems? Should I return to my buggy m4?

    This happened to me but more of a random switch for me. I didn't change motherboards or anything. Hibernate just randomly starting taking about a min and randomly sped up too. I wish i could say I have a solution for you.

    Thank you anyway, I have reinstalled xp and all the drivers and still the same, so I think it have to be a power problem.

    When I was mounting the pc it drained my battery, and since then it haven't had a total charge, may it bother?

    So now, I only can think about five problems:

    1. The mobo is the problem; it is completely new but there is something wrong.

    2. The m2 doesn't feed the system well (20pin)

    3. The battery is drained so I must charge

    4. The hard disk is a bottleneck (don't know why, it worked well before, maybe power?)

    5. The RcJoycon makes my system start slower (about 10 seconds slower) and sometimes the mobo stays waiting for something when it is connected and I have to reset to start. Edit: This is not the problem because I have unplugged the rcjoycon and the problem is still here, but what is happening with it? It was warking well before...


    Any idea?

    Well first of all, you probably might wat to take a few things out of the equation to make it easier to diagnose whats going on.

    1) You have to charge (or replace) the car battery, if its very low its gonna be erratic.

    2) You said the details in the bios dont stay as you set them, is the onboard battery (the little disc shaped battery on the MB) dead?

    3) Any way you can get a laptop power supply (brick) and test the PC and M2 startup and shut down in the house ? As long as the brick is the correct voltage, and your car pc is wired in a common way (red lead = constant 12v, white lead = accessory power and black lead = ground) you just need to connect the positive from the brick to the red and the white wries and the negative to the balck one.

    If you can get it running and restarting properly outside the car you may have better luck getting it installed and running in the vehicle.

    This is the first thing I'm gonna do.

    It seems to be random, it keeps the details but not the time/date, and some times it does

    I didn't want to do it because my system is deep over the glove compartment, but I think I am gonna have to buy a laptor psu and try this; the wires are correct; how should I connect it to the laptop psu? (yellow/black wires?)

    If it works outside the car, what should I do?
