Dell Precision M3800 does not illuminate

I ordered a Dell Precision M3800 and as soon as I got it out of the box, he had immediately problems start. The button lights, the lights on the keyboard would turn on for a few seconds, then everything would be closed. It worked once in a while if I removed the power supply cord or if I tried different combinations of remove/insert the power cable and press the button. I took it into the shop and they replaced the motherboard and now it lights up at all. The assistance service said he turned on to them, but it turned on once for me after pressing the button + 20 times, but never turned back after that.

I asked a replacement computer, but in the meantime, does anyone have any idea what the problem might be or how I can turn to recover my files.

I got my M380 for about 8 months and this week started having the same problem. I found that remove my Logitech usb keyboard/mouse dongle wireless enabled at startup. Its got the last 2 days and both times I could do nothing to start. Both times I removed the USB dongle has started the next test. It's frustrating.

  • Dell Precision T3500 does not start

    I have Dell T3500 Office, I pressed the Start button and the lamp on the Start button began to blink for a few seconds with a noise of power supply (SMPS/PSU) and 1 and 3 flashing and lights out. During this time I have observed that the power supply fan GET making small movements but does not turn the LED on the motherboard (orange) lights. I tried to start again and again, it does not work.

    Is this because the PSU become defective? or simply a RAM issue? I removed the RAM cleaned and then re inserted but it went past too to no avail. Can someone help me please to solve this?

    As the 3847 bought two days earlier, better to return to the store for a refund or a replacement.

  • Windows Vista does not illuminate

    Hello

    My computer does not illuminate. I have a Dell XPS M1530 with Windows Vista. The problem started yesterday when I left my computer unplugged. When I got home, the screen was blank and I just assumed it was gone to sleep. I pressed the power button and the power light turned on for a brief moment, and then turns off again. Then I turned off the computer by pressing the power button. When I tried to turn on the computer again, the lights on top of my computer, such as A / V controls, enlightened to the mode of the normal sequence, the player makes the usual click and the power button lights up for a short while before leaving. The computer turns on then with the fan running and the little power on the front (not the power indicator main on top), but light a screen empty. Thanks to all this, the screen remains empty, including turning point works manually.

    By pressing the power button when the computer is turned on gives the same result as the first time, where the main power light on the power button lights up briefly, then turns off again without result. Pressing F8 when starting the computer also does not work. I don't know how I'm supposed to solve this problem, the screen never showed any activity during all this. Help please!

    I should note that when I turn on the computer, it would seem she's asleep sleep and rest, as the little light on the front of the computer and the fan turns slightly, while the power led is off.

    Remember - this is a public forum so never post private information such as numbers of mail or telephone!

    Ideas:

    • You have problems with programs
    • Error messages
    • Recent changes to your computer
    • What you have already tried to solve the problem

    It seems you might have a hardware failure, as nothing is displayed on your screen at any time after power on.

    If under warranty, contact the manufacturer of your computer.

    If not under warranty, contact a local and trusted computer repair Shop (not a type of chain stores to the repair facility).

    See you soon.

  • 660 s does not illuminate

    I have an inspiron 660 s which does not illuminate.  The green power light is on in the back.  Nothing happens when I hit the power button.  No lights or the beeps.  The machine is about a year and a half old.  Tried to unplug and power drain.  Still nothing.  Help please.  Thank you.

    "The green power light is on in the back.

    Not this indication, the power supply has no questions.

    As the power button does not lite and there no beeps, then I would suggest replacing the power by a "Known" work unit, as it is required to test the system and motherboard.

    It would seem that power Inspiron 660 s is an owner of Dell unit, because of its shape and size.

    You will need to call Dell spare parts to the 1-877-717-3355 and "Service Tag" of the system increased from hand.

    Otherwise, you could buy a compatible power 660 s from here:

    You can always update your firmware with iTunes. But it seems you might have a larger, likely hardware problem with your phone.

    Try to restore the firmware with iTunes. If this does not help, make an appointment with a genius at the Apple Store.

    My 2009 iMac monitor is black and does not illuminate.  It has been connected to different computers, macbook pro and a mac mini with the same result. Is there something that can be done or is it just toast?

    Try to zap the PRAM or reset the SMC.

    Otherwise, take the model to your local store from Apple or a DAD.

  • New Ipod Touch does not illuminate

    Buy IPod Touch last summer (August 2015) and died this morning. Can not activate it or it will load. Any suggestions?

    Try the following steps:

    1. Press and hold the home and power buttons at the same time for at least 15 seconds until you see the Apple Logo.
    2. If this does not work, load your iPod for at least 10 minutes, or until the Apple logo appears.
    3. If none of the steps above do not work, here is a link to give you more information: If your iPod touch does not illuminate
    4. Be sure to contact the Apple support if you need more help.

    Good luck!

    Satellite Pro C660 does not illuminate. no noise, no light just fill out the dead.

    any suggestions?

    Hello

    On this virtual path, it is not possible to provide an accurate diagnosis. All you can do is to unplug the power plug, remove the battery and leave it for a while. Then press the power button and hold it for 15 or 20 seconds.
    After doing this connect the power running and try to start again.
