Dell xps 8700 wont power on

DEATHRAMENTDEATHRAMENT Member UncommonPosts: 701
in Hardware
I recently bought a new dell xps 8700 which im now having a problem with. Yesterday when i got home from work it was powered down(i never turned it off), upon pushing the start button nothing happens. Ive reseated the ram but no go. There is a button on the back of the psu which when i hold down will spin the fans. But will not start the computer. I changed the psu but same issue. I can see a light on the mother board that is on when plugged in called aux power i think.

    Why are you performing a lobotomy on a "new" computer?  Isn't it under warranty still?  They will ship you a replacement computer.

    Step 1: Plug in a keyboard? (Believe it or not this should always be the first thing checked, if you don't have a keyboard plugged in, most computers won't even respond to the power button.)

    Step 2: (Or even step one, any order is fine really.) Double check all connections, completely remove and reinstall if need be.

    Step 3, which may not work as wiring may be different: on the I/O jumpers unhook reset and power, plug reset into the power pinout, if this works, your switch is bad and needs replaced.

    If none of the above, either RAM, which you already checked, so that shouldn't be an issue, or the like, Don't dig too deep, I guarantee you that your problem is simple. But I could be wrong.

    Let me know your progress and details, I'll help where I can.

    Contact Dell. They charge premium for their computers, but in return they have a good warranty.

    Do not start attaching/detaching/moving any components inside the computer case. It's more likely to void your warranty than fix your problem.

    Happened to me once, turned out to be a loose power cord.  Step one:  Always check the physical connections.

    It won't void a warranty to check power cables, nor open the case. Only exchanging parts, such as the processor. Warranty even supports RAM upgrades and storage installs. As long as the original parts are in case upon receiving a defective unit.

    It doesn't void the warranty, but when you start attaching/detaching/moving things inside the computer case, the technicians who make warranty repairs will usually notice that. Noticing it will lead to them to wondering if the problem is something caused by the user instead of something they have to repair under warranty.

    As long as the computer is under warranty you should not try to repair it yourself, you'll just risk losing your warranty.

    Detaching and attaching all the cables outside the computer is ok, but trying to repair a computer that's under warranty by fiddling around with its insides is something only a pro should do.

    Whoa... I missed something here. You changed the PSU? You do know that prebuilt computers DO NOT have the same pinout connections as ATX form factors etc!!!! Put the old PSU BACK before you kill that board.

    I know it's a pain to box (You did save the box for awhile right?) it back up and send it back but that's what the warranty is for as others have said.

      Since he changed that PSU out, he killed it, warranty is definitely voided in that circumstance. However, I've been looking into the parts, it's an ATX PSU and can be replaced. I'm wondering what else could have gone wrong here. Signs point to user error.
  • DEATHRAMENTDEATHRAMENT Member UncommonPosts: 701
    Actually i called dell and he told me to reseat the ram and the change the psu as i told him i had one here. He said it would not void the warranty. he had me open it up and check different things.

    Do you mean a constant clicking sound all the while it's plugged in, or just a single click when you attach the power cord?

    A single click when it's plugged in might be a natural sound. I remember I used to have a PSU that would leak a bit power when plugged in and cause all the fans to move just a bit.

    A constant clicking shouldn't happen. Most likely cause for constant clicking would be some motor that's stuck (fan, hard disk, or DVD drive), but none of those should have power on.

    If there's some error in the computer, some motherboards do beeps to tell you about the error, but that would be beep -like sound, not clicking sound.


    EDIT: If the Dell support OKed switching the PSU, it wouldn't hurt to also spend a few minutes testing all the cables inside the computer to make sure they've been attached properly.

    Normally I'd also recommend resetting BIOS to see if that helps at all, and maybe trying to detach some components that aren't required for booting, but I think in this case it's better to do those things only if Dell support tells you to do it. /EDIT

    USE the warranty!  It's what you paid for when you bought a manufactured computer.

    Where is the clicking sound coming from? The PSU, HDD, optical drive, motherboard, somewhere else? Is there a pattern to the clicking? If so, what is the pattern. Clicking from the PSU > bad PSU, HDD clicking louder than normal (Can you easily hear it more than a foot away from drive) > bad HDD, Optical drive clicking, bad optical drive or check for a misaligned disk and remove disk . MB clicking/beeping is an audible error code.

    If the PSU and CPU fans work that normally  means the PSU is ok. There is also an LED on the PSU. It's supposed to be green if good, red if bad when the button is pressed. 

    If the fans don't run the standard method to test a Dell PSU is to unplug all PSU cables except the main motherboard cable. This includes the removing the CPU power connection on the MB. Unplug all external devices except keyboard, mouse and monitor. Press the button on back of PSU, Do all fans run? > Good. After each test, plug something in (CPU connection first!). Push button. If fan's don't run then you just plugged in the faulty device.

    You can also try resetting the BIOS.
    1. Unplug PC from wall.
    2 Push the power button to try to turn on the system. You're trying to drain the capacitors.
    3. Remove the battery from the motherboard. 
    4. Wait 10-20 seconds and put battery back in.
    6. Plug in system and turn it on.

    If it works then you fixed it and might want to replace the battery. If you call Dell they might send you the battery or send a tech with a battery.

    If you call their warranty support and feel like ranting then keep the rant focused on your PC or Dell. Don't attack the phone tech. Get them on your side. Let them know you aren't angry with them. If you can't understand the tech ask to be transferred to another tech and state why. You won't get a level 2 tech or their manager.

    Okay, good deal. Have you solved your issue locally or are you having to send it in?

    It's cheaper for Dell to send a walking/talking screwdriver than to pay for 2 way shipping.

    Having built a fair few pc's and work as a hardware installer ive NEVER found a windows pc that wont power up without a keyboard plugged in. - Yes you might get the post bios spam about "no keyboard detected"

    In fact the only unit ive ever encountered that wont power up without keyboard is the old Sun Servers

    ^^them old things :)

    But ive never known a windows pc HAVE to have a keyboard plugged in

    But like everyone else is pointing out. bugger trouble shooting you paid over the odds to buy dell, so just phone dell and tell them you want a replacement as clearly with a problem its not fit for sale and should be replaced.

    This post is all my opinion, but I welcome debate on anything i have put, however, personal slander / name calling belongs in game where of course you're welcome to call me names im often found lounging about in EvE online.

    The only reason you would even buy a prebuilt computer is because you can send it back if it doesn't work.  If you're going to spend the time trying to fix it for them, you might as well have built it yourself.
  • DEATHRAMENTDEATHRAMENT Member UncommonPosts: 701
    I opened it back up a unplugged the HD cable CD rom, cpu, Case fan and video card but the clicking sound remains. I think it's coming from the board.

    Wait for the spark... when the smoke appears, grab your nearest fire extinguisher.

    Warning!  Using a fire extinguisher on your computer will void it's warranty.

    get a paper towel or toilet roll tube. point at different stuff and listen to the other end until you know where the sound is. 

    In the end there should only be two things that should make any sound on the motherboard. The CPU fan and the beeper. If the sound isn't coming from them then that clicking noise is most likely an electric short and the motherboard or whatever is clicking needs to be replaced . With an electric short on the MB then the CPU and RAM might also be damaged. 

    Call Dell.

    Depends on default BIOS features. What does windows have to do with it?

    Every board in my house does this by default: Gigabyte z97-hd3, Asus a88x-plus for the active boards. It can be changed in the BIOS menu. I like this feature for desktops, should I wish to change them to servers in the future I can just disable it.

    I've seen a BIOS that displays error message when keyboard isn't found, but BIOS that refuses to power up at all without keyboard is a first for me. Usually they try to power up enough that they can display the error message.
