ACER 5750-6845 Black screen at startup - no postal codes?

Hello everyone I'm hoping that someone has experienced this problem before that I'm stuck!

My ACER 5750-6845 laptop computer is unbootable after working perfectly for two years. When you turn it on blue light comes on but no other activity, beep codes no post, no BIOS logo screen.

I tried the static 'cold start' reset, tried the exchange of USB keys and it does nothing. This isn't a CPU card or replaceable graphics. It was working one day and then just stopped the other.

Any ideas? Someone else had this and resolved?

Thank you very much for your comments!

Graphics card problem. As you already know which in your case means a motherboard problem.

I'll take a wild guess here. It is NOT a device on the motherboard problem. It's a connection problem or the connector of the device.

The easier and less frightening to solve problems are a connector problem. You probably already have some of this. Remove the battery and get the thing again. Replace all accessible connectors, you can find. So before you piece it all back once again, gently reinsert the battery, it works and hope for the best. Obviously better do all this on an insulating surface, although it is outside.

If the above does not work, a line of welding or soldering connection has probably has been peeled off or cracked on the motherboard. To fix this, you must first prepare you while you wait for the results of Google search of these two words "solder reflow. Hope that you are not faced with this task, but unfortunately at this point I think that a rupture of the weld is more likely than a connector problem.

  • S7: black screen on startup

    S7, barely a month.  Order last night, left pending, lid and power cord plugged in.

    Today he won't move beyond a black screen at startup.  Starts with the start screen "Acer Explorer beyond the limits" and then just black.  However, I can see the pointer of couse to the screen and it can move with touchpad and mouse.

    I rebooted several times, power cord unplugged, etc..  No luck.

    Looking, seems I'm not the only one with this problem.

    Come on Acer, I dropped a lot of money on this machine!  Help, please!

    Here's how I fixed my problem as described in my original post (for now, anyway):

    Unplug the power apparatus.  Open the cover; computer will power on but go to black screen.

    Power off button on the side, but leave the lid open.

    Then, with (2) lid open (1) the computer turned off and unplugged from power cord (3), press and hold the power button / stop for 30 seconds.  Computer will be quickly implemented on and then turns off quickly (you'll see the Acer logo startup screen, but he died before entering the black screen).  Keep holding the power button / stop through all this for 30 seconds.

    At the end of 30 seconds, the computer will be (should be) off the coast.   Remove your finger from the power button / stop.  Leave lid open during all this.

    With lid open, connect the power cable.  Press the power button / stop as you normally would (you are not holding it this time) to turn on.

    Computer should start normally.

    Worked for me; It may be useful if you encounter the same problem.  I said that it has something to do with static buildup.

    Before contacting a professional Toshiba authorized service provider would be, it would be interesting to know if you have seen improvements after recovery procedure and BIOS updated.

    If, after installing new check usability of portable and so similar issues still persists.
    If nothing will change it s is strongly recommended to communicate with an ASP.

    Hi poly

    Please put more details on the problem, because it s not easy to say what has happened without any detailed information. You hear the operation of the HARD disk or fans?
    Switch you to other devices to display, before this problem occurs?
    Unfortunately it FN + F5 key combination doesn't work if the operating system has started so it could be a malfunction of the equipment. I don t think you can solve this problem by yourself. In this case, the only way is to contact the service.

  • B540 TDR and black screen on startup

    Hi all, I bought a B540 in April a power works fine until end of July when it began to show the error "display driver has stopped working and has recovered." a few days later I let him (I have need as a wifi station to connect devices remove) and after a few hours of work, when I came back, the screen was off and there wa no way to turn it on. I press the power button for a few seconds to turn off the pc and he died. When I turned on, the computer started but the screen is off (not the 'lenovo' logo was shown on the eve) but everything else seemed to work (play plug/unpluging usb external hard drive the sound of the carachteristic). I turned off again and wait ten minutes before the market again, this time above the 'lenovo' logo was shown, but it seems that the pc failed to boot win 8. I unlplugged everything, removed the power cord, wait an hour and after that all started ok but the error message "display driver stop" was still there. After this date the computer randomly starts ok or with the screen. Given that I do not use it intensively Isuspected some windows update to cause this strange behavior and I'm trying to use a point of restoration, until July 17, but the problem was still there. Then I removed all recent windows update of June on, and I realized that in one case, it was not possible (i.e. the "remove/uninstall" button not showed that KB). I googled around and found the subject KB has been reported to broken system and the only way to react was to use a DOS command to reatore a new installation of the system. I did and actually everything works ok for 2 days (one day, I actually use the PC all day to upload stuff to iternet it to work). Unfortunately, after that day, everything seems to repeat: new 'pilot not resposinding to display' and a black screen at startup.

    Please consider that the system is quite new and clean (only 3/4 months of life) and everything works fine until end of July. What do you suggest me?


  • Power outage during Vista SP2 install; black screen on startup of the PC

    Hello-

    I have a PC desktop Gateway which is no longer start after a power failure has occurred during the installation of Vista SP2. The computer displays the progress at the bottom indicator, then, before that can display the login screen, the screen goes black, with a white cursor. CTRL-Alt-Del and Ctrl-Shift-Esc do nothing.

    I tried without success to the following:

    * Safe Mode/Safe Mode control guest - boots to black screen new
    * Startup Repair - told me there is nothing wrong
    * System Restore - tells me there is no available restore points
    * System restore the OEM DVD - can not find hard drive
    * Re-install this is disabled because I can't start Windows Vista-

    There are * all * options other than wiping the disc/lose all my data? The PC is in a remote area and backup drive is not an easy thing to achieve.

    The PC is no longer under warranty of the bridge, and I understand that Microsoft supports is no longer installs OEM of Vista.

    Can anyone help?

    Thank you

    I can tell you how to make bootable disks, but you already have a disk.

    He has changed since good means of XP repair install from disk by booting from it.

    I would add that info to disk Bootable repair, just in case your DVD is a factory of one computer.

    http://www.Vistax64.com/tutorials/88236-repair-install-Vista.html

    It's Vista only repair installation option these days.
    It must be switched on!
    Not much use, is it!

    Good luck with it.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Download the ISO on the provided link and do a repair of the disc.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

    http://www.bleepingcomputer.com/tutorials/tutorial148.html

    Above information shows what the process looks like and a manual, it load the repair options.

    NeoSmart containing the content of the Windows Vista DVD 'Recovery Centre', as we refer to him. It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

    Read all the info on the website on how to create and use it.

    ISO Burner: http://www.snapfiles.com/get/active-isoburner.html

    It's a very good Vista Startup Repair disk.

    You can do a system restart tool, system, etc it restore.

    It is NOT a disc of resettlement.

    And the 32-bit is what normally comes on a computer, unless 64-bit.

  • Pavillion dv6 6b15ed: Driverupdate to fix the black screen at startup windows 10!

    Hello

    Question:

    Is there a new driver is released for my AMD Radeon HD card 6755 2? (double grafics)

    Because the latest driver causes a black screen at startup. Sequence: wenn turn on u see hp and that start-up logo win 10 after that it crashes on a black screen for about 2 minutes, then start 10. (about 2, 5 minutes later)

    I have now installed a windows 8 (issues) driver and windows starts in 6 seconds (with normal hard drive).

    I can't play the games but the bootspeed is good.

    So is there a fix or is there is 1 entry?

    TNX

    While the video card is not supported with the latest drivers.

    You can update as much if you want to, but isn't is not helping.

    Even in charge AMD said that this card is not supported with drivers.

    But today, I tried 1 times more, I used the old driver AMD_Display_13.352.

    With the first reboot, it was still black and some errors of the pilot, but after that the second quick start installation restarts!

    Appearance of the logo Windows 10 only 3 or 4 seconds and start immediately, without black screen and I got sound, video and video tube work as well.

    If other people having the same problem download Drivethelife and download the old pilot 13.352 and see for yourself.

    Make sure u delete all drivers previously installed with DDU (Display Driver Uninstaller) of guru3d site.

    Almost forgot: I also disabled windowsupdate to prevend install other drivers (new).

    Greetings

  • Black screen at startup, unable to boot from the CD

    I did something wrong on my Thinkpad T43 2668, now I have Black Boot screen cannot Access IBM, can not press a function key, cannot start from the CD.  Here's what I did:

    1 got unwanted winxp sp3 updates automatic, then restored to the permeable point via Windows XP system restore, then, cannot start system; cannot boot from the Windows XP CD

    2 2 demarrer start from Linux Live CD, format hard drive and install ubuntu, hidden Partition of domain is not deleted, always there;

    3. can start Linux OS, but black screen on startup. There is no way to see what's happening at startup; Pressing a key of function or IBM bottons returns no result, always boot in Linux;

    4. cannot boot from any CD bootable legal except Ubuntu Live CD;

    5. no means of access Bios to set the boot sequence, therefore, cannot boot from USB floppy either.

    Advice is appreciated!

    PS. I tried Linux live CD some time ago before this trouble, click on "help me to boot from CD", got something installed. I guess it's something installed out of the box and that is why now I can boot from a Linux Live CD.


  • Corrupt BIOS V5 531 Acer black screen after startup, f2 and f12 also. Repairable?

    Hello

    Yesterday I tried to install Win 7 if I could play D & D Neverwinter on Arc after using * nix systems study (looking to start a career as an administrator). I had plugged into a power strip that was, unbeknownst to me, turned off and I went to make coffee and watch some news. When I came back to check the progress of my laptop was powered off and since then I havn't been avle start without being blocked at a black screen after the start page of the bios. The f2 and f12 also leads to a black screen, I can not change the boot device or enter the bios Setup.

    Is - fixable at all? For example, is the a key-combo, I can use it to restore from a backup bios? Or, do I have to bring in a technician who can install a new chip bios or flash this old some how? Or did I brick pemanently my device?

    V1.22 is what you want to be part of a unit of Windows 7.

    The problem is if it crashed during the upgrade process, it will take some special tools clearly on the chip on the MB and recharge it with a new BIOS. I would contact your local support team to see what options are available.

  • Acer aspire m1201 black screen

    When I start windows movies from my computer to a black screen, Ive tried the system restore, install drivers missing and non-functional. McAfee is all this so far with no problems detected. I can get on the computer by pressing f8, then go to low resolution screen and mode without failure, but not normally. It worked for a bit of roll back to a previous display adapter driver, but eventually it stopped working. I can't find anything wrong with it and uninstalled programs that we no longer use. The computer worked fine until we turned on after a weekend away! In addition, it is just out of its warranty. I went to back to factory settings, but did not get a disk of vista with it as it came pre-installed. Help!

    How to get Vista recovery Media and/or to use the Vista recovery Partition on your computer.

    There is no Vista free download legal available.

    http://support.Acer.com/

    Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

    Normally, they do this for a cost of $ small.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    In addition, ask them if you have a recovery Partition on your computer/laptop to restore it to factory settings.

    See if a manual provided with the computer or go to the manufacturer's website, email or you can call for information on how to make a recovery.

    Normally, you have to press F10 or F11 at startup, Acer should be Alt + F10 to start the recovery process...

    Another way I've seen on some models is press F8 and go to a list of startup options, and launch a recovery of standards of plant with it, by selecting the repair option.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Ask them if you can also make recovery disk/s of the recovery Partition of hard disk or system failure crash when you're facing up and running again.

    They will tell you how to do this.

    Every computer manufacturer has their way of doing recovery disk/s.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
    A good Vista DVD contains all versions of Vista.
    The product key determines which version of Vista is installed.

    There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

    If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

    I have no idea what to do now.

    HI Joonair,

    You can install Windows recovery media that you have created (USB stick or CD/DVD drive)? This recovery media contains an image of the factory settings and in general it is always possible to install the contents of the recovery media.
