    I have a HP OMNI 100-5154 ALL IN ONE .and I went to bed, in the morning I tried to turn on and nothing. there is power to the motherboard cause I can see the light lit at the plug, and I can hear th fan running. I went through the steps from the web site but nothing works. just thought somebody here my know something. thanks.

    I take it that you powered down then PC the night before (turned it off completely)?

    Is there power to the monitor? Are the monitor connections secure?

    My only other suggestion is to unplug the unit from the power source and let it stand for a minute or so before plugging it back in. This could possibly reset the computer.

    What kind of suggestions did HP give?

    It couldn't be the power supply since the fans come on.

    Have you looked inside the unit to check for any loose connections? Sometimes, the harddrive connectors can work loose.

    I tried but all I could get at is the hard drive memory and processor, I don't know how the rest of the back comes off, I ran out of screws to take out and iam afraid to just pry the rest off.

    yea they gave me that but that's as far as I could go. they don't show how to get the rest of the case off to get to the motherboard.

    Hi, Is the machine out of warranty? How old is it?
    You would need a USB keyboard to input any codes?
    I've seen these Omni units and it scared the living daylights out me for the obvious reasons you're stuck with. :eek:
    There will be very little you can do as it would appear to be another throw-away type unit. :mad:
    The copy of the service manual shows you how to replace the DVD unit - the HD - RAM and that's it. :confused:
    Best bet if it's still under warranty.---Neil.

    What kind of power supply? Is it a DC transformer/power block, or an internal power supply? I note computers typically use 3 voltages, 12V, 5V, and 3.3V - which are then "stepped down" into other voltages used across the motherboard. Fans spinning typically only indicate the presence of 12V. A failing power supply can output 12V just fine, but fail on the other "rails" with the other voltages.

    These have the same problems as notebooks - they don't conform to the ATX Form Factor standard that PCs conform to. That is, they tend to be proprietary, using proprietary parts, and often, proprietary coding in the BIOS. For this reason, it may be necessary to take it to a shop where they [hopefully] have experience with these systems (and they are liable for any collateral damage done during disassembly).

    The fact the keyboard, which runs off 5V, does not light up (I assume you mean the Num and Caps lock LEDs) suggests to me either the power supply or the motherboard itself. :( Not good.

    Since I see 2011 reviews on this machine, I assume it is out of warranty. If you can gain access to the motherboard, I might suggest you reset it - by pulling the CMOS battery (after unplugging from the wall, and discharging any static in your body by touching bare metal of the case interior). If you get this far, I would just replace the battery. It is likely a CR2032 wafer battery which you can get at most battery/camera/watch counters at your local discount or home improvement store. Do not touch the new battery with bare fingers as skin oils promote corrosion and attract dust. I put a clean cotton sock over my hand. Once replaced (touching bare metal again before reaching in) boot directly into the BIOS Setup menu (if it boots!), set date and time, then Save and Exit and hope for the best.

    If a new battery does not fix this and it does not boot, you are only out a couple bucks and then I am back to what I said above, you need to take it to a shop.

    If you can get access enough to pull the hard drive, you might consider pulling it and installing it into an enclosure, or as a secondary (NOT boot) drive in another computer to copy off any files you don't want to lose.

    Sorry about that. I didn't know you tried all that already.

    If not told specifically what was tried, no way you would - therefore nothing to be sorry about.

    Let's hope it is something you can check.

    Thanks for clarifying things, Bill.

    That info could come in handy later on.

    Well, the power supply should be labeled to say what voltage its output is. But after that, like a notebook there will be internal power circuits that break it down, distribute, and regulate it from there. But without a full service manual and/or schematics, you will not likely be able to determine what is where. :(
