• XPS 8500 does not turn on, power supply problem

  XPS 8500 shipped on 18/01/13 so only a little more than 1 years. does illuminate, check psu and it's fine. reduce mobo or power button module. want to try to bypass the module by jumping pins on the mobo, problem is that I can't find any list of the pins for mobo or power button. Any help would be greatly appreciated since comp is barely over the years and cannot afford a new right now. Called Dell but no help it cause guaranteed missed, which took them 5 transfers and 45 minutes to tell me that :)

  If the green light on the power supply goes off, it detects an anomaly. So, it is not the power button that does not work.

  1. Visually check all ports USB for damage, misshapen or twisted for example contacts
  2. Try to turn on with nothing attached (no keyboard, no monitor, no mouse, etc.)
  3. Setting power off unplug and power button press / hold for ~ 15s open the case and carefully reconnect all RAM modules and PCI cards in their locations. Check the power cable from the power SUPPLY mobo and CPU. Cable control to all readers, video card etc... Pull the mobo battery and power press on/hold button for ~ 30, replace the battery (right-side-to the top).
  4. Check the cable to the module button before (F_PANEL connector on the mobo)
  5. Check before USB cable to motherboard
  6. Etc.

  The manual is hereif you need information about all of these connectors.

• HP Jet 11: 11 flow does not illuminate. Power led flashes 3 x

  I am trying to fix a 11 HP flow for someone and I'm running into some issues here.  Basically, the computer does not light and the power led blinks three times.  I did all the options to reset that I could find online, and the power brick works.  The person said that she may have fallen, so I think this has something to do with that don't turn only not on.  No idea what the three blinking lights could mean in this case?  Thank you.

  Hello

  Flashing codes mean.

  1 blink = CPU does not

  2 flashes

  -L' laptop can load if given enough time.

  -If the laptop starts to load, try to start the BIOS of several times the ESC key until the Start Menu appears. Press the F10 key to enter in BIOS

  > Started the laptop?

  -Yes. The laptop started

  -No, the laptop is not started. At the moment, it seems that the BIOS is damaged.

  3 flashes = Module of Ram error

  4 flashes = failure of the graphics card

  5 flashes = hardware failure

  6 flashes = BIOS authentication failure

  I hope this helps.

• Tecra M2 does not start - the power light AC blinking orange

  Someone at - it a list of codes for the Tecra M2 flash.
  My friend has a laptop that does not start at the top. the AC power LED flashes orange. a long, short, long, short, long, short, long, short.

  I checked the battery and reinstall the RAM.
  Any IDE?

  Hello

  I agree with go.
  The ASP would be able to tell what means error.

  Usually means short and 1 long: 0
  So the error must be: 1010 1010
  Due to the last significant bit (LSB), to be read by behind:
  So it now means: * 0101 0101 binary *-> it must be converted to hexadecimal-> * 55 Hex *.

  Then, you will get a hex code.
  But unfortunately, I m not very well which could mean this code

  So ask ASP for help!

• Dell Studio 540MT does not start, green power light on, but the Start button / clear stop completely

  Looking for assistance

  Have a Dell Studio 540MT (purchased in 2009), worked great until 2 weeks ago.   After a temporary system failure would not start.    The power light itself is green fixed.   The power button on the front panel is completely released.

  I read a lot of messages and other information about a similar problem.   Therefore, I did following:

  1. unplug everything, press the power button / stop for 1 minute and retries.   without success

  2. replace the CMOS battery.  without success

  3A jumps the Green and black 20 supply connection wire pins to motherboard.  It started immediately food, fans and hard drive.   so I assumed that the PSU has been authorized.

  4 replace the motherboard with a new mobo.  Curiously, in a first time, there was no change, but after about 2 minutes, the power button was working and power system.   Everything worked so very well.   I had also completely cleaned all the dust in the chassis and radiator, fan and had applied the thermal paster as directed by Artic Silver.   I even turned off after hours of race and restarted system.  Restarted, he noted that it took a couple times by pressing the power button to make it work.   Then the 2nd day I shut down the system by a normal shutdown through Win 7 and let rest for about 10 hours.   When tried to start/turning the power on again, same problem as the original problem... at first, before light power button would show amber flashing when first pressed the power button / stop, then once I unplugged the power cord and let it sit for 1 hour, the light power button showed no light, completely and again no restarts.

  5. I ordered a new power button cord (new)... This could be the problem and replacement will fix?   Is this a known problem that power button can cause this kind of problem?

  6 or is a problem of power supply?   But you wonder why the green light of the PSU and works very well when jumping the Green and black wire on the connector 20 pin?     Before I go buy a new power supply to other suggestions?

  Is there a known issue with button / stop itself and/or PSU on Dell Studio 540 MTs?

  Yes, the front panel can cause failure to start in some models, although I don't specifically remember if the 540 has been affected by this problem. Please let me know if the replacement resolves the problem.

  ATX power supplies should work. Here are the standard components of the Dell desktop computers.

• 18 XPS does not start, the power light will not stop flashing

  I was upgrade this computer to Windows 10, I did install one instead, but the children had spyware which even then showing upwards. I did a refresh, there no I did an installation and finally got in windows. Some updates installed and restarted.

  The computer was bricked since. The only thing that happens is the LED which indicates the power above, the button will not stop flashing white light. Connected or not connected, after having held down the power button for 5, 10 and 30 seconds, the led stops flashing for a while and then again. I tried several points of sale. No idea if it is a coincidental breakdown.

  I'll change that.  I went back in and re-removed the cable from the battery.  I also removed the CMOS battery cable this time... I was at least an error message on the screen and access to the BIOS!

• HP 8710W (p/n: GT648PA #ABG): 8710W does not start - the battery light flashes orange 7 times then 1 green.

  Troubleshooting done so far: I removed (even the RTC) battery, hard drive and memory. Hold the power button for 30 sec.

  When I re - install the battery and press the power button, it flashes 7 times orange, and then Green 1. Same thing happens with or without the power supply is connected.

  The laptop does well (no fan, no disc doesn't sound etc.) and the screen stays off (i.e. no splash screen).

  I thought it was a dead battery, as it was 8 + years, so bought a new replacement. Unfortunately, there no fixed and I still have the same problems with the new battery.

  How to decode what mean hot flashes?

  What else can we test it before I bin the laptop? I would have preferred not to do so as he has been a full rock performer and the 17 "display is fantastic as a desktop replacement.

  Any suggestion is appreciated.

  Thank you.

  Unfortunately, this seems to be a motherboard problem. After eight years of service, it is left for a digital camera never never land.

  Unfortunately, it's time to bin and source of a replacement book.

  You can retrieve data from the hard drive using a cable or a drive enclosure hard usb 2.5 ".

  I understand your disappointment. Workstations are portable very special and very expensive to replace.

• Toshiba Camileo P10 does not turn

  I have a toshiba camileo p10. The problem is that the camera does not turn. I tried to recharge the battery, but the red light blinks for hours.

  I tried without the battery and the charger plugged but nothing happened. I cleaned the contacts.
  All solutions?

  Have you removed the battery AND the AC adapter?
  Try this. The two parties should be removed/disconnected.
  Leave the camcorder for some time (a few hours). Press and hold button power 30 sec long. After this plug in the battery and charger.
  Wait until the battery has been charged and then try to turn on the cam by pressing the power button.

  Good luck buddy.

• Satellite PRO U300 does not turn off

  Hello

  I am facing a problem for the last few days on my Satellite PRO U - 300 (31st PSU)...

  The machine does not turn off and the power light stays on (blue LED) even after you have disabled. In fact, happened 3 - 4 times when I start the computer normally by pressing the power button / stop, it does not start and I noticed that the indicator was not extinguished even after + shut down +. Like any it is blocked! I have to finally, remove and reinsert the battery to start the laptop.

  Some details of my pc are as under:

  Version of the OS Microsoft® Windows Vista Business 6.0.6001 Service Pack 1
  BIOS Version V2.00
  Processor Intel (r) Core (TM) 2 Duo CPU T7100 @ 1.80 GHz

  Can someone help me solve this problem. Is it possible that during the uninstallation of programs, any perticular driver file is also deleted?
  Thank you

  JITENDRA

  Hello

  I don't know that you understand the indicator of power, but to me it sounds like AC Power LED and this LED is always on when the laptop is connected to the power supply.

  Power on / off LED is probably what you mean (the other starting on the left).
  Anyway, you turn off your laptop using a standard on the Start button?
  Are you sure you want to use the Hibernate mode.

  Believe me, the entire description here is pretty confusing to me. It may be that the laptop is turned OFF but power light is still on.

  Have you installed something 4 days ago? Or deleted some important application?
  Sorry, but it is not easy to say with certainty what the problem is here.

• printer does not turn on

  My Deskjet 6980 printer has stopped working.  It has worked very well so far. Flashing lights said he needs ink. I put in the new ink. Now, it won't turn. The power supply is turned on, the works of output (without surge protector), but the printer does not turn on. In all he has no light on the printer, except light power cord in the back. I tried everything I could find online, but nothing works. My computer was still recording the printer, but since it will not power, says that it is in offline mode. Any suggestions would be helpful.

  The unit may have developed a power failure, but may be also simply in a State of error because of the fresh cartridges.  There are a few steps, I'll try in this case of troubleshooting.

  * If possible, try to remove the cartridges that you recently installed before performing a hard reset of the printer.

  * Hard reset of the printer by unplugging the device, disconnect the other end of the power cord from the wall outlet, separates the power cord of the power supply, wait 30 seconds and plug it back up.

  See also the steps described in the document, found here, to solve a lack of power.  I hope this helps.

• L50D-B-146 satellite does not turn

  Hello

  I have a problem with my L50D-B-146 turns is not on. Very rarely, when I try to turn it on it works. Once I managed to turn on I tried to upgrade the Bios to 1.6 1.2, but you must restart your computer to complete the installation I couldn't because it does not turn on 99% of the time. The laptop didn't work before I tried upgrading the Bios is not the fault of the installation to fail. Also when I get to turn Windows works perfectly fine, until I have to turn it off again.

  When I try to turn it on the power button light works and you can hear the fan, otherwise you may not even see the screen Toshiba Leading Innovation, so I don't think it's the fault of the window. I repeat again once you can activate from time to time, but very rarely. Also it is not the fault of the monitor that I connected the laptop to an external display, and again, there was a problem.

  I would be very grateful for any solution to this problem

  The solution to this problem?
  I don't know if anyone here can offer virtual diagnosis and offer the working solution.
  When the machine works sometimes such a problem is not easy to understand. Such behavior of the laptop must be analyzed and may be tested with diagnostic tools.

  What we do here, it's just to speculate at what may be the problem. Looks like the BIOS related issue. For some reason, from time to time your machine cannot pass the BIOS checking the material.

  Have you already contacted Toshiba services and asked for help?
