(Redirected) Precision M6500-white screen on startup and black screen on reboot

Hello my Precision M6500 has recently begun to behave badly and has following symptoms.

1 display a white screen on market and a black screen on reboot, the OS boots aand, one that can discern by the jingle of windows at the end of the startup procedure.

2. the unit turns to the insertion of the battery.

In order to isolate the root cause of these issues, I tried the following without success.

1. replacement memory

2. new display motherboard cable assembly

3 start with on the SSD on the system, and even at the bios level that the symptoms remain.

Anyone knows similar symptoms with their unit and if what was then the final fix deployed to solve these problems.

The system is running an ATI graphics card I read a little about the black screens in booting with Nvidia cards, can anyone confirm if all the info out there has any application for ATI cards.

Thank you

  • Satellite U300 - white screen after reboot

    I have a 3 yo Satellite U300 (with Vista), which was usually in good working order until this morning. It froze a little bit when I had iTunes open so I restarted. He now has a completely blank screen.

    I tried to stop and restart several times, I tried to plug it into an external monitor and have tried to remove the battery and drain the power I had read recommended on another forum.

    It also seems to be from running as it should (turns on, fan is on, etc) but I can't get anything on the screen.

    Any ideas?


    If you can t get an image on the external display, it appears to be a malfunction of the motherboard, CPU, RAM or anything, but the internal screen should be ok

    Hmm. In your case, I had read this article, maybe it helps:

    In the worst cases, you need professional help of an authorized service provider. Guys can check your laptop and repair because they have access to the databases of Toshiba and order new parts.

    Good luck! :)

  • MBP 12 - hangs at startup and the screen Glitch


    My good-condition, end 2012, 15 "MacBook Pro under OS X 10.11.4 is ill. There are two apparently distinct questions:

    • When starting, it does not get passed to Midway as indicated by the gray bar. It crashes and gives the time, periodically warms and turns fans.
    • From the start, the screen has a distinctive glitch superimposed on it that never changes or falters: a series of horizontal blue lines on each fourth-or-so row of pixels.

    The problem started by wakes the MacBook to sleep and it gel. Eventually had to hard - reboot, and now here we are.

    I tried:

    • Start in Recovery Mode: (now ⌘R to the boot) hangs on white screen directly after the Apple-logo-and-progress bar screen, not a lot of help.
    • The PRAM reset: (now ⌥⌘PR) unfortunately has no effect.
    • Start in Verbatim mode: (now ⌘V) Always crashes, but it could provide a few tips:

    In the image above, you can see the above glitch, the blue lines. (Non-glitchin boot Verbatim is just white on black).

    If in any sense, the last printed line is always this:

    en2: promiscuous mode enable succeeded

    More information:

    The reason why the boot in Recovery mode does not work maybe because there is no recovery disk partition. When you start while the possibility to select the startup disk, there are only two options: Macintosh HD and BOOTCAMP. Recovery disc or something similar is also meant to appear?

  • Tecra A11 - 113 - white screen and the cursor of the mouse during the boot


    My Toshiba Tecra A11-113 with win 7 32 bit boots with a mouse cursor and the visible white screen.
    I tried to start under different boot options. Mode, safemode, last repair job configuration
    and msdos command only... all these startup options give the same result.

    I also tried with win 7 32 bit dvd, but same result.

    I am able to access the C drive by booting with a linux key, so the data is visible.

    Can someone please give me a solution?

    Thank you

    What happens if you access the BIOS? Is menu visible on-screen BIOS?
    Turn on the unit F2 button and press.
    This should allow you to access the BIOS.

    If you will be able to access the BIOS and see everything as usual, then the screen is OK and I think there is a problem with your installation of Windows System.
    So boot from the Toshiba Recovery disk should help you solve this problem.

    You said that you already tried to boot from the Windows DVD disc is this Toshiba Recovery disk? In my opinion, you use this disk to restore the laptop to factory settings.

    When I boot A85-s107 in battery power, it is get booted up in the background, but my screen is empty.
    After that if I connect it to AC power and switch deactivation/activation of the laptop power button, the screen comes back to life.

    Battery is fully charged and computer will work off the battery voltage if I remove AC after boootup

    Any suggestions?


    also note that when I remove AC and then reconnect I start the computer on two occasions that it does not start the 1st time?

    Don t need to recharge the battery if the AC adapter is plugged ;)

  • MacBook 13 "mid-2007 - startup white screen error

    So I have a white MacBook, 13 ' mid-2007, with 500 GB HARD drive, processor Core Duo (not Core 2 Duo) and 2 GB of ram, and it has a problem. Then, one day I was in front of the thing the House of my friend and jumped out. Flipped the lid and the MacBook was closed. Weird. I used it just before loading a Word document before my departure. I pressed the power button, and I heard the startup chime classic. Then I heard something not so classic. "Click-click! Click-click! "I think," what in sam *? "as the white screen appears and seems to never end. Just the white screen and the snap of what I assumes that the hard drive. Nothing works. The strange thing is, its JUST a white screen. No Apple Logo, no folder with a question mark, no crossroads, not just white. Even more strange thing, is, he does not meet the startup commands, such as holding the C, alt, command-R, etc., except the eject button. It could eject discs. I tried everything to get the thing to start SOMETHING, with a Recovery Mode, OS X installation disc, a USB that came with my MacBook Air, which contains the operating system it is running, the OS X 10.7, Lion. I even went all try to install Ubuntu on the thing, with a disk I burned, but that's when things got really climb. The wisest eject button work anymore and now the disc is stick in there. Couldn't get anything out. Nothing. Just click-click and the white screen of death.

    Oh and by the way, I could possibly recovering my data from the hard drive? It would be great. I worked with this computer. =)

    Hi Pete Spong

    Thank you for using the Microsoft Answers Forums!

    I would like to ask you a few questions to help focus in the right direction:

    Since when you receive this error message? Have you made changes to your system?

    Try the following steps:

    Step 1:

    Put the computer in a clean boot (namely if any third-party software hinders the process)

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7


    Check with step 1 (run a clean boot):-If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem.

    Continue with the remaining steps to pin-point on the third party service.

    (Note: after find you the problem causing the program, you will have to perhaps to update or install a newer version of the program and also don't forget to put the computer to a normal startup)

    Step 2:

    Install this update if it is not already installed on your computer and check.

  • BlackBerry smartphone White screen and hour glass, can't do anything

    Occasionally by BB has a white screen with an hourglass, the latter for a few minutes

    It the first time I tried it turn off, which did not help, so I removed the battery and turn on the power, and he returned to the white screen with the hour glass.

    So I thought that maybe this is a update being pushed by Verizon or BB, couple of days later I plug my BB to USB for laptop and check the updates of BB, nothing there, OK. So I tried Verizon update, you know what number that your call and it ask you if you want to update your phone (don't remember what it is right now)

    Someone else has had this, are there any patches?

    Thanks in advance for your help


    Sorry for the problem with the hourglass and display...

    Each unit of a battery pull restarts, the screen will appear empty for about 1-2 minutes during startup.  If you load ok and continue to have the hourglass appearing frequently, there may be a somewhenre of files sorrupted who maintains the processes that the BB must load - not 100% sure, but if there is a corruption, you might want to consider your phone by using the Fund mgr and performing a master handheld wipe (backup options security options (gen settings, touch menu and then select wipe Handheld)

    When restore you... A full recovery can restore the corruption on the phone, so...

    There is an advanced Fund mgr backup/restore option allowing you to restore specific databases such as Contacts, calendar, etc...

    BTW... the more - the number of programming made up air is only to update your device with VZW towers, dealing with mainly the roaming capabilities and the # * 228.

    I hope that helped you!

    Also check the Compatibility Center (for the compatibility of the device)?

    Check with the system and peripheral manufacturers for updated drivers and many have special instructions
    to help the upgrade to Windows 7. Check for updated BIOS, chipset of low-level drivers and ask for the
