Compaq dc7100SFF: PC refuses to start

Hello

Yesterday the Unit indicates that the CMOS battery was almost exhausted, but I checked that and it is still showing 2.9 volts. While the envelope was opened, I blew some dust/lint, I could see without disturbing all the components out of the battery, even if I did move some wiring but do not unplug everything. About boxing the device upward, the PC will not turn on and when the Start button has been pressed the "power" LED flashed 5 times with associates beeps. That is still the situation. According to me, this indicates a "defective or missing memory", but to what memory that doesn't reference at no time worked out the memory cards. I understand that I will probably have to reset the CMOS but how to access if the unit does not illuminate?

Thank you.

5 beeps is a memory problem.

Some of the dust that you blew up had him.

Just go out and clean it with a soft tissue paper.

Do this only if you know how.

  • Windows Easy Transfer refuses to start. How can make us it work?

    The old laptop of my son is a Windows 7 laptop. He recently bought a new laptop for Windows 8.1, and naturally he would like all its data, etc. migrate to the new machine. So naturally he's trying to use Windows Easy Transfer, but it does nothing for him. Whenever he tries to run it, it gets this error:

    Window easy transfer has encountered an unrecoverable error. Pleas restart the application.

    There is no other errors than that. He tried to launch Windows Easy Transfer normally and as an administrator; always had this error.

    He tried to connect in safe mode, but he refused to run Windows Easy Transfer at all.

    We have grown to a prompt as an administrator and run SFC/scannow, but it is no problem at all. All is well for what is Windows 7, Windows Easy Transfer should work. But he is not and refuses to start.

    We even chose to return to a previous restore point, but who does not work either.

    Since all this can't work, how in hell are OK, we supposed to get Windows Easy Transfer to work on this old machine Windows 7 when it will not be under all the circumstances I've specified here, work?

    (Moved to programs)

    Hi Rod,

    I apologize for the delay in response.

    It is likely that the Application cache is corrupted and causing this problem.

    Please, try the following steps:

    1. Go to "C:/Users / / AppData/Local'." "
    2. Delete folder named Migwiz.
    3. Try to run the transfer Windows Easy now.

    Hope this information is useful. Response please that if you need assistance or have any other question about Windows, we're here to help.

I cannot access the bios by pressing F10.the bios version was F16 and flash by F20 .will help thank you very much.

    I'll have to return a verdict of laptop motherboard bricked due to a failure of the BIOS upgrade. Sorry, but it happens.

    This means that this would require the replacement of the BIOS chip to make it work again.

  • HE commands to work - Compaq Presario SR5000 does not start

    I have a Compaq Presario SR5000 running Windows Vista Edition family basic and once we got in, I first cleaned the internals to the air compressed, then tried to start, and it failed, so recommended BIOS I run the Startup Repair tool and so I did, and the startup repair couldn't fix the computer "automatically".

    Now, I run the system restore and I tried to restore the computer to its last Windows Update, and I got the error code 0 x 80070002, meaning that the system cannot find the specified file.

    Specifications for the Compaq Presario SR5000 I have:

    AMD Sempron LE-1250 to 2.20 GHz

    2 GB PC2-6400 DDR2 SDRAM Samsung

    Windows Vista Home Basic

    HP M2N86 - THE mother

    Power supply PS-5251-08 LiteON 250W

    Well, if this is the case, then I think you may try to access BIOS, if that does not work then go ahead with the HARD drive option. I had this problem before and I wiped the hard and it worked eventually. If this does not work, I will try and find a different solution.

  • Compaq evo n610c does not start

    On May 7, 2010 my Compaq evo N610c would boot is no longer using a battery 1 years and a power adapter c bought the same year (2009). Without battery back installed and using only a c power, I noticed that the front battery light flashes constants 8 consecutive flashes. Installing battery below with a trendy c, the indicator light flashes 8 times once then stops completely. No boot or indications of electricity except the 8 consecutive flashes. How can I fix this problem with your technical help?

    Do all very simple, basic stuff first and don't complicate questions take your time, this is a must. Take a rest if nessessary. Then go back to the difficulty of the laptop not operating, disconnect the laptop from the wall. Then remove the battery, memory (ram) chips and then remove the hard drive. Then reconnect the power cord for your laptop computer and the wall outlet. So, or if you receive the same light that flashes in the battery of the portion of front indicator along while your laptop is connected then finally power, it could be the small battery watch itty-bitty plugged into your motherboard the fancy name for it is the battery CMOS. Find it and take it out... Wait a minute! Reinstall the battery itty bitty. Your laptop should start, if other difficulties with any operational material occurs, spend 5.00 to buy another battery to your local convince store. Take your computer before hand to a technician for repair will cost you at least $180 and they tend to feel guilty to charge you that much either... Just for $5.00 battery replacement. See, I answered my own question taking my own time-same guy who wrote the community for technical assistance. Thanks to all and you're welcome.

  • Compaq Presario S4500UK won't start after disconnecting from the wall outlet. What is a CMOS battery problem?

    Reconstruction of recent software with HARD drive internal extra (March 2011) under Windows XP/Linux dual-boot installation worked fine.  CD/DVD RW drive, started giving errors so replaced cyclic redundancy check drive a week ago.  All still OK.  Change of electricity supplied and increases energy use conciousness off the machine to the outlet of the overnight after normal shut down.  Machine will not re-start not in the morning.  Not load BIOS; all lights came briefly and then die after 3-4 seconds with power still led on.  You can get a similar effect by plugging the keyboard into the PS2 Mouse Jack I did once!

    After 20 minutes or so try all kinds of things managed to boot from the CD of Linux.  Shut down/restarted and everything is fine so I don't switch off at the wall.  Also seems to be OK after brief power off for 5-10 seconds but the problem persists with any long disconnection.  It seems that after 10 to 15 minutes from power-on and 2-3 attempts to restart, BIOS comes up and all is well, but he stopped in the middle of a start of Windows or Linux on a couple of occasions.

    Am I right in thinking the problem might be the result of a dead CMOS battery?  The reason that I ask is that the clock seems to keep time OK and there is no apparent problem with the BIOS once it loads.

    Any help/advice would be much appreciated.  New config info below.

    Dual boot Windows XP Pro SP3 of Compaq Presario Bios v3.03 S4500UK / Linux Ubuntu 10.04 Lucid (2.6.32 - 33)

    Recently installed HL-DT-ST DVD - RAM GH22NP21 replacement NEC ND - 1100

    +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

    I don't have all the answers so I went forward with replacing the CMOS battery, but that did not help.  The problem is also obvious if I turn it off and leave it for an hour or more before trying to restart even if I do not unplug the wall plug.  It seems to take about 15-20 will start again before it fires.  I would be really grateful for any clues as to what is wrong.

    OK, guys.  I finally solved the problem.

    After you have calculated the power needed for the config curent, I discovered that, using various ways to estimate, he walked between 321W - 383W.  It was pretty weird that the only thing I added was a HARD drive and a memory stick and the wisdom of the other guys on this forum, it's that there is a lot of capacity within the factory installed power of 250W.  Yes and here's the rub: the modern replacement devices usually have upgraded capabilities and use more power.  And so when I replaced the drive CD/DVD RW added a few watts, as the sectoral approach of the floppy drive.  It appears also that the optical USB mouse needs more juice than the good old PS2.

    I just installed a new 450W PSU Powercool and Bingo!  The processor is faster, too.

    Hope that my pain and trauma saves someone else having to suffer the same.

  • Compaq Presario F768WM does not start

    I have a presario F768 that no longer starts.  Blue power light is stable, power cord.  When I press the power button, the blue power lights the button lights up with the power led and hard drive indicator.  After a second, all the lights go out.  power indicator at the front goes out for a second, then back.

    I tried the hard reset, remove the memory and disk hard and always the same symptoms.

    It started after an update Vista hung and computer had to be turned off manually.

    Looks like your motherboard has gone bad, I know that cell phones series F700 comes with NVIDIA GeForce Go graphics. What plauge of HP and Compaq laptops. what you call sounds just like what everyone has experienced this same problem.

  • Compaq Presario CQ61-406SA not start.

    Hello

    Was given this computer by a friend to try to find out what is wrong with it. It does not start and the Caps Lock/Num Lock LEDS give a flash code that seems to indicate a CPU problem. Have reinstalled the RAM, wireless card and the hdd - even. Have tried to start without anything plugged - even. Tried the hard reset - same. And we tried the reset of the BIOS (windows + B) - still the same.

    As it is out of warranty (expired on August 27, 2011) I was wondering what could be done. What would be the best package of care to buy... If the owner is willing, of course.

    Thank you

    John

    Hello

    Have been in contact with support by phone earlier today and the price quoted for repair is excessive (€253 / $331) in the age of the computer, so the owner will get a new one instead. Thanks for the reply anyway

  • G780 refuse to start - Help!

    I have a laptop G780 and current running Windows 7, everything was good, until a few days ago. I've been on Google Chrome portable froze on a Web page. Had to turn off. At startup, laptop computer loaded with the Windows logo, and then black screen. Left for an hour, no change. Turned off and tried to start safe mode after loading files, he went to black screen. Left for an hour, no change. Power off and is gone to startup repair... after loading files, he went to black screen. Left for an hour, no change. Swiched off and pressed the button a recovery of key... He went to a photo of screen with green leaves and stayed like that, without change. It seems that I can not start the laptop, or to recover. I tried to put the first start up / recovery disc I burned when I bought the laptop, after changing the boot first to the DVD device. It started upward for the Windows logo, black screen then. Can it be recovered or is the unit for the tray?

    No help from Lenovo or someone here... not deserted island?

    In any case, I fixed it myself with the uploading the plug of diagnosis on the support site.

    If someone reads this, it worked very well.

  • Compaq 56z-200: does not start

    In my view, an overheating problem.   He always ran hot, even when it is new and clean.   Wife and children insisted on holding their towers to use and also blocked vents a problem.       Symptoms: 1) the final a few times it would start the a/c with an error message (battery failure) (this only refers to the main battery only or the BIOS battery?)     (2) after 10 or 15 minutes of use a gray screen blocking.   Let it cool would allow it to restart.     -How distinguish the problem I did one last backup with starting on a USB key.    During other troubleshooting with impulse of air to cool the screen turned gray and I was to turn it off, the screen quickly started to turn red from bottom to top, and then it turns off.  -Since then, it does not start, even using the USB key.   It lights up, the fan seems to work and it gives an indication it is powered (a/c), but none of the keys work, and the caps lock light flashes 1 x per second continuously.   QUESTION: I've already replaced the computer.     Is a throw away the old, or something simple and inexpensive could record for games or surfing the net safely?    Y at - it parts worth saving, HDD, RAM etc?    My computer, a Comqaq 2000 seems looks the same, except for the name.

  • HP Pavilion dv4 screen black 1428dx / refuses to start up

    I have problems with my laptop (HP Pavilion dv4 1428dx) the last thing I did was paused, then cameback and tried to wake him up but it would not start up. All the lights are on, but the screen is black and the only thing that I hear the fan moving. The caps lock and num lock keys have a light flashing, not really sure what it means. The power light, battery light comes on, but the hard drive LED is not on. This computer is nearly 3 years old and I've never had a major problem like this until recently. If anyone has a solution that I'd be happy to appreciate them.

    Thank you for your time,

    Freshman4002

    The blink codes State caps lock/caps lock Num because it might be just the caps, just the number lock lock, or both.  If both blink, then it counts as a blink every time.

    If it flashes once and a break of 3 or 4 seconds, then tells the CPU POST test failed.  A processor failure usually requires a new processor, but some have been able to open Notepad for reinstall process and apply new thermal paste to get the problem resolved.

    If it is under warranty, I would advise you contact HP for service.

    If it is out of warranty, then I would contact HP to get a quote and compare that to the cost of a local PC shop to weigh your options.
