Studio XPS 1640 does not start. No bios, no control of fan. Volume + / illuminate, flashes of silent light...

I have a Studio XPS 1640 (model PP35L) that will not start. Fires along the sound card light upward from left to right and back (as it should), but then stops. Them increase volume and low lights stay and the mute light flashes.

The cooling fan is not test, or do anything else. Nothing on the screen or the other.

I have re-seated ram to check it was OK

A Google search is supposed to replace the motherboard. I did this and the problem persists.

Someone at - it tricks, tips or advice please?

Mike

Thanks for the reply! The problem was a crooked PIN. Once I straightened the PIN and reused thermal paste the laptop worked perfectly. I don't know if I did it, but I didn't have the old motherboard to see.

Thank you!

  • Studio XPS 8100 does not start

    Hello!  I have a 2010 studio xps 8100 (Intel (r) Core i7 CPU 860 to 2.80 GHz, 8 GB ram) and it's great when it works.  Last week, I was out of town and when I came back it would not start upward.  I can turn it on and start the fans, but it does not pass the POST and therefore does not start.  I tested the ram and it seemed ok (two beeps when trying to boot without ram, no beeps when ram is correctly placed).  The original of the graphics card died last year and I had it replaced with an EVGA Geforce GTX 750, I chose because it was one of the few cards that could work with the power supply 350w provided with your computer.  I thought that maybe the PSU was then replaced by a 500w PSU, but the problem persists.  I then read somewhere that if you SNYC date/time problems (which I was when the computer would turn on) that you need to replace the battery on the motherboard, so I did and still does not start.  I don't know what I can do, is the dead motherboard?  I tried the drain the power thing (release the button so that disconnected power for 30 seconds) and that didn't work either.

    maddygillis
    Yes, but I'm sure that the battery is not the issue.  If it was I'd get stack codes error beep (5 beeps).

    Not necessarily...

    maddygillis
    It does not pass the POST because it does not start...

    If the video card is faulty, the PC can still start but you just do nothing appears on the monitor, so I don't know that you can actually say that it does not pass POST.

    When you have tested the monitor with your laptop, did you use the same cable and video port on the monitor that you use with desktop? If you have used another port on the screen with the laptop with the office, this is not a fair test.

    Have you tried reinstalling the video card into its slot and check the connections of the video cable at both ends?

    This system has onboard video and Pluggable software component video card. So, you can remove the add-in card and switch the monitor to the onboard video port. According to the specifications, the onboard video has HDMI and DVI outputs, so assuming that your monitor supports either people, you have an easy way to test more.

    NOTE: The embedded video ports are DISABLED unless you physically remove the video card. If you cannot move just the video cable to a built-in port while the video card is installed.

  • Dell Studio XPS 435mt does not - light light orange card mother

    I had my Studio XPS 435mt for recent years and love it! Normally I leave my machine on almost every day all day so I can access it remotely. Well, today my power went out (the product is connected to a good surge protector) and now it won't turn back on.

    When I plug it in there is a green light to the rear of the machine and internally, there is a orange light, which lights up. When I press the power button nothing happens, not even try to power on. I read a few forums that suggest all of a new power supply, a new motherboard and even a job to 'put your motherboard in the oven' random.

    So my question is can I do anything to check what the problem is? Also, if it of a motherboard problem and needs to be replaced, where is the best place to get a motherboard? Reference Dell sells to them directly or I have to go to a 3rd party to track down?

    Thank you in advance for your help!

    A type of power surge Strip does nothing to protect the PC during a power failure.  You need a 'UPS' unit to protect the PC during short power outages (most).

    As he ran, anything could have happened to the power supply to the motherboard to a component on the motherboard.

    As you have the power to 'keep' alive on the card mother, indicated by orange LED, power supply works somewhat.  Unplug the power connector 24 pins on the motherboard.  Then the rider GREEN wire to a BLACK wire and see if the power turns on (fan running).  If it does, it does not say the PSU is good (only replace it with a known good power is the only true test for a power supply), but it does not say the rotation of the problem is not in the power.  If it does not start, food is the likely problem.

    If the power supply lights the other most likely problem is the motherboard.  Reinstall (unplug and plug back in) the prior panel connector on the motherboard and then give it a try. If it still does not respond, the motherboard is suspect.  The power switch, itself, would be a very remote problem.

    Dell is a source for a replacement motherboard.  There are sites that sell Dell used/given to nine motherboards and ends up with a google search.  Only another mother of exact replacement fit and work.

    Finally, regardless of the tests do or anything that seems as it isolates a certain part, unfortunately only to replace the part really tell you if it's bad.  To avoid buying something you don't need you can make to a PC repair center renamed to what is really wrong.

  • Dell XPS-8900 does not start

    Worked well to date, 01/01/2016 - Happy New Year, NO!

    Change power cable, use a different outlet (other items such as router and network printer can very well). Computer still does not start.

    When I plug it in the computer power light turns on light and then turns off (this seemed normal before). So if I push the power button computer does not start.

    I don't seem to get an orange light sequence of 2-1 after trying to turn it on - and continues. Maybe some sort of signal POST?

    I can turn the computer (not my first choice) after our journey ahead. But I'd rather get it upward and now running. Have work to do.

    Phil

    More information. I had four USB3 external drives attached, whose two propulsion and two disks Seagate Wireless - which is recharged through its USB port.

    Removing only the second Seagate drive allows the machine starts. So the question can be too much of a drain on the USB card current.

    Once started, the system seems to work very well with that wireless Seagate drive attached, and it restarts with it attached - just not boot from a condition of Shut Down.

    Not sure really, I understand that, but I can live with that.

    If someone seems something more insidious in this behavior, please notify; bought the XPS-8900 at COSTCO and still about 55 days return if it is defective!

  • XPS 8300 does not start

    I put my pc in sleep mode after you have finished with him and he's going to return to what it was when I push the power button. But this morning when I press the button, it does not start. All I can see is the cpu fan began to turn for 1 second and stopped and this process repeated subsequently. I unplugged my PC and I tried to reboot, but still no luck. Any suggestions?

    clockwork_orange

    I ordered the new mobo and also some thermal paste and cleaning an antistatic wristband. I also have an anti-static bag ready for wireless card should be stored in. I also have the service manual ready to guide me through the process. Are there other boards or pieces of advice that you can say about replacement like for like the mobo and all the other parts? I've never done this before so although I'm confident enough to try it, I'm still a little nervous that I could make a stupid mistake for example, short to the Council before I even turn on. After installing everything what can I expect to turn on my PC and it will boot as if nothing had happened? -C' i.e. will my files and descktop always look the same? do I have to enter the bios at startup in the first, so yes it what could I do?

    Thanks for any help, you can suggest!

    Rebecca

    Rebecca

    Everyone has a first time, just take your time, read the instructions carefully and keep them perhaps practice as a reference.

    A clue, as there no way of knowing at what age the MoBo, is, it is better to replace the battery, a 3V CR2032 Lithium coin battery is required, they are cheap to buy and it is easy to replace before the MoBo is installed.

    After installing everything what can I expect to turn on my PC and it will boot as if nothing had happened?

    If everything of fine, Yes, but there is always the factor X [aka unknown].

    IE will be my folders and office always look the same?

    It should be.

    what I have to enter the bios at startup from the first to the top.

  • XPS 8700 does not start after the upgrade memory RAM

    Dear members of the Forum.

    I have a XPS 8700 with the following specifications:

    Core i7 4770 k

    2 TB HARD DRIVE

    16 GB of Ram (4 x 4 GB)

    NVidia GTX 660 (1.5 GB)

    BIOS version A10 (later).

    RAM sticks in my current system are all Micron Tech (here) 4 GB DDR3 SDRAM PC3 12800 240pin 1.5V 1600 MT/s.

    I had two RAM modules of tech Micron (here) 8 GB DDR3 SDRAM PC3 12800 240pin 1.5V 1600 MT/s so that I can move on to a total of 24 GB.

    After the discussion here and here, I installed the modules in slots 1 & 2 (both white) so that the system is not able to start. Not even got the bios screen. I also tried 3 & 4 configuration (both black) I ran my computer with the two 8 GB sticks only, with the same unfortunate results.

    I also saw that it is a normal problem of compatibility problems between the types of ram, but I consider that this is not the case. In addition, bad positioning of the modules is not also the case because if I put my old ram glue the computer starts normally.

    I used tape you will static isolation.

    Is the problem, a problem of compatibility between my computer and the RAM modules?

    If the RAM is damaged does these effects (do not start)?

    How can I check if the RAM modules are damaged?

    What would be your suggestions?

    I thank very you much in advance!

    Mauricio

    Hmm, I'd say you two bad sticks of RAM.  If the system POST even with them, I would swap them if you can.  We know that the RAM slots work because you have 4 x 4 sticks without any problem and your computer can take up to 32 GB of RAM.  Your admission that you bought the right kind of RAM, voltage, and speed, etc., so that shouldn't be a problem.  I would say as bad RAM.  When you do not install, just check that you make pairs in each of the colored slots, for example. matching pairs in the slot of white and black.

  • External port eSATA Studio XPS 9100 does not

    Hi all

    I have a Dell Studio XPS 9100and external eSATA port does not work or it is not detected. I have a Seagate FreeAgent external drive and it can't detected, and it is NOT power up when I plug it into the eSATA port. The FreeAgent drive works fine as it is detected on my laptop Dell Studio XPS 1645eSATA port. The drive is detected on the 9100 when I use the USB cable to the drive (plugged into a USB port, of course).

    I tried to do some research online and some suggestions were to activate via the BIOS eSATA port, but the eSATA port is enabled in the BIOS. The wrong driver is installed on the device? I see the Intel ICH10 Family 6 Port SATA AHCI Controller-3 has 22 in the Device Manager. Is this the right driver to recognize the external eSATA port or is there something else wrong with the 9100?

    Does anyone think that the external eSATA port requires an external drive with its own power supply? The 9100 is a 2010 model year environment, but I think it should not require a player with an external power supply.

    Thank you in advance for your help!

    Hi all

    I grabbed an eSATA disk that has its own power supply (AC adapter) and trendy source on eSATA back port and he recognized the car.

    It seems that the Dell Studio XPS 9100 has of an old eSATA port requiring a drive eSATA that she is clean in order to be energy source active on its external eSATA port. If you try to use a disk without its own power supply eSATA it won't work because the former eSATA ports enabling the way as the USB ports and the new USB ports hybrid eSATA . My laptop Dell Studio XPS 1645 a hybrid one of these ports so apparently it is why my Seagate FreeAgent working on it and NOT on the 9100 desktop. You can't plug a USB cable in the 9100 eSATA port certainly isn't a hybrid eSATA port.

    I guess I solved my own question.

  • Vista does not start after BIOS flash

    I recently flashed my BIOS for my Presario SR5152NX by Vista after having downloaded the file directly following from the HP site:

    http://h10025.www1.HP.com/ewfrf/wc/softwareDownloadIndex?softwareitem=PV-66758-1&LC=en&DLC=en&cc=us&product=3436821&OS=2093&lang=en

    He seemed fine, because he then asked me to restart my PC, I did.

    When it restarts, BIOS seems to be fine but once, he's trying to get into windows Vista, it will NOT start, and instead, I get a BSOD with the following STOP error message:

    STOP: 0X0000007B (0XF789E640, 0XC0000034, 0X00000000, 0X00000000)

    I tried searching for this error, but I do not get a clear answer to what it means.

    In addition, by choosing 'use last known Configuration' always produces the error, and I can't get in any security mode in the start menu.

    I can't enter in Vista, please help.

    I have solved my problem, but please keep this up for the other reference...

    It turns out that the error has to do with a "BOOT DEVICE" error. Once I read that I feared it might be a faulty drive. This was not the case.

    It seems that after the BIOS has been flashed, he changed the order of loading on my readers, and so it hurts than as a master. I guess expected Vista are on it and wrong. What I had to do was go in the motherboard configuration by pressing F10 on the diagnostic screen, and I had to spend my disk drive to configure the Vista disc as the main (has priority on the others), using the + and - keys on the numeric keypad.

    EUREKA, now charge well Vista again and the BIOS is updated correctly.

  • Dell XPS 8500 does not start after the interruption of system restore

    It was one thing to do, but I turned off my PC during the restoration of the system because he took time to complete the process.  The next day I couldn't boot into windows.  I tried the automatic repair feature, but it does not work.  I tried to repair windows using the orignal installation disk, but it does not work.  I tried to install Windows 8 all over again, but I got an error message - media pilot is missing.  I opened the box uninstall the RAM, videocard unplugged and both drives and reinstall, but without success.  I noticed that there is an orange/orange light on the motherboard.  I thought it was the hard drive at the beginning, but now I hope that this is not the motherboard.  Any help will be appreciated.

    You have damaged the image beyond repair.  You need to reinstall from scratch.  Windows to say that an optical drive driver is missing, bad copy of DVD-RW, DVD + R or DVD - R media that was not burned at 1 X 2 X or 4 X, so is not readable.  This is why USB Flash Drive 16 GB or more is recommended rather than the DVD player to the installation media.
