White screen on battery

Hello, I have a laptop DV7-7008tx Pavillion with Windows 7-64 bit. I have a problem when the laptop is only on battery power without power supply running only on current alternative. When it's on battery, when I close the laptop, it automatically turns off the power to the screen and when I reopen it again, the led lights are on, you can hear the sound of snoring normal laptop does when turned on but screen is blank and the key no matter what I try tap just won't show. I updated the drivers and BIOS from this site but still no difference. The only way to retrieve display on is to force the stop pressing the button for a few seconds then turn it back on and the message at Windows startup stopped unexpectedly. Any ideas?

P.S.: This problem does not occur when the plug is plugged in with/without battery.

You can read this thread. The user has installed the latest graphics driver and it has solved its problem, which happened to be identical to yours.

  • First white screen of death, now black screen on the internal, external screen works

    Hello

    a few months before I could not suddenly start my macbook more. He had the white screen of death and absolute no functionality in addition to its departure.

    A few days ago I got the macbook, open/close a couple of times so that it is operated and suddenly the keyboard LED lit and the screen

    turned black. I realized that he really started and connected to the external monitor. everything works fine now in addition to the internal display.

    I run Apple Hardware Test mode clamshell, but extensive testing even said that there is no material errors.

    can I conclude that my screen is not faulty? I thought it of the graphics chip, but wouldn't the AHT it detects then?

    Another thing to mention is that the battery should be changed (warning hint)

    I tried PRAM - & resetting the SMC without success.

    I would really appreciate any kind of advice.

    Thanks in advance

    The symptoms you describe point to a faulty screen or display connection.  Make an appointment at an Apple store genius bar for a final assessment.  The event will be FREE.

  • Satellite C855 - white screen after BIOS update

    Hello

    I am a beginner user,
    I have Satellite C855
    Yesterday, I downloaded a 'update BIOS"that was sent to my computer.
    Since that my screen is blank, there is a hum in the background.

    I have a recovery back up on my external hard drive, but of course, the screen is blank so I don't know how the product.

    I think I must have downloaded a model or the update was not compatible.

    Hello

    White screen do you mean that nothing appears on the screen?
    You see the start screen of Toshiba, or if you are able to access the BIOS?

    Where this is not possible, try this:
    Disconnect the power adapter, remove the battery.
    Press and hold the power button for about 30 seconds.
    Then connect the two parts (batteries and AC adapter) for the laptop and try to turn on the unit.

    In case this would not solve the problem of the laptop, I'm scared of m the BIOS update was not completed successfully and I think that only authorized Toshiba service provider would be able to help you.

  • Satellite C650D-007 starts with a blank white screen

    Hello world

    I need emergency aid, 3 weeks ago, I bought this new laptop from Futureshop.ca and now, today, I pressed the power button to turn it on and when it does I get this white screen of white.

    I even tried removing the battery and connect the AC and it always produces the same thing.

    I can't believe after that only 3 weeks it has stopped working.

    PS: it feeds on. just a white screen empty. No logo nothing.

    Thanks in advance.

    Hello

    In the past I didn't had this problem but it must be hardware related issue, so you need to do is to contact Futureshop, explain the problem and ask for replacement.
    Second option for you is to contact the nearest Toshiba service directly. They can check your laptop and replace the defective hardware.

  • Satellite Pro M40 sometimes starts with white screen

    Hello!

    I'm pulling out my hair with this problem.

    For no definable reason that according to me, my laptop will start with a blank screen.
    Not all the time, but, seemlingly, whenever it feels like I need extra help stress on my plate.
    For the most part, with perseverance (starting with or without battery, with or without the adapter, with or without pci with or without mouse usb network card and any combination of these elements), it ends by lights correctly, but sometimes Nothing that I won't get it to start and show me a screen.

    My M40 is 4 months old.
    Since it's purchase sent to Toshiba for repair twice for this problem, when I have exhausted myself trying to coax it into life. Whenever he was sent by saying either the problem has been fixed, or that he had no problem found/all systems ok / "it works very well for us, after testing all week."

    This week [edit: it was Wednesday], I sent it to me, and Yes, I checked the trunk upwards and gave a sigh of relief that there is an image on the screen.
    I wrote a letter to this topic a day or two later (that day he first gave me a screen white, but on closing down and restart, it was fine).
    Today, however, not a week later, I have a white screen again.

    I am reluctant to send for repair again, due to the stress involved and the time it takes and the technicians speaking it works for them.

    If anyone can help, or was faced with a similar problem, please respond.

    Oh, and the solution does not lie with the keys FN + F5, because I tried several times... unless there is a way to 'special' to build on them, I'm not in the running for!

    [Edit]: several hours later, as a demonstration of her bored this problem is, my screen is once more working.

    I went on once again, at the time and no joy. Then, after switching OFF, count to ten and the restart, eureka.

    I'll update with news as it happens. If there are all the necessary specific details about "switching on the environment", just let me know.

  • Stor.E TV + White Screen of Death"

    My box packed yesterday, surprisingly 1 day after her 1st birthday! All I get now is a white glitter on the front panel display.

    Means that the box has not experienced a catastrophic failure, or did I suspect a blockage of the software. If it is the latter, how do I do a hard reset?

    The script was:
    I transferred files from the box on my home network. This went well.
    I navigated to the folder video using the remote control, selected a video I want to resume playback.
    The curriculum vitae of confirmation popup does not work, he bombed at the store screen logo then at home.
    I've sailed to the video and allows FFx16 to get to the point where I wanted to. It has bombarded the logo again.
    I noticed the screen says "loading" Panel, while the logo showed, then returned to the House.
    Thinking he has hung up, I thought that a reboot of power would be sort so I turned off with the remote control.
    I gave it a few minutes and then power on. The screen showed just a flickering white screen.
    Then, I disconnected all cables and power supply and left for an hour. Once again, same WSoD under tension.

    I noticed other comments on this forum ask questions about the reset of the box, but someone is there never an answer that worked?

    I can't do any connection box to my pc of office on site with the USB device or the network cable on a browser by using the intellectual property which it had sold.

    Since it is under warranty I opened the box to look for a jumper to reset, no luck. Also, no sign of battery backup to perform to get first start start. The design is beautifully put together with the help of SMD components and connectors firmly waiting. I disconnected a Samsung 1 TB Sata HD, then reconnected when he put it back together. He turned again on same buthe WSoD.

    Someone at - it ideas on how to this reset to life?

    TIA
    Malc

    Hi Malc

    > I noticed other comments on this forum ask questions about the reset of the box, but someone there never an answer that worked

    You can reset the Stor.E + only in the configuration of the system Stor.E. There is an option called default restore
    But if you are not able to get the system configuration, you will not be able to restore the settings so that this option is useless in your case

    Looks like its common 1 TB SATA 3.5 HDD you could connect it to a USB port using a controller USB-to-SATA it is maybe you would help to gain access to files on the HARD drive otherwise I guess the HARD drive died.

  • Pavilion beatsaudio 11-n012na: white screen with the AC adapter is plugged in.

    laptop worked fine with W8.1, but after installing windows, 10 screen is blank with power supply is plugged in. Laptop starts up OK, but with a white screen, pulling the adapter allows image appear, no other problems. Battery charge OK but cannot be used while charging. This didn't happen with windows 8.1

    Hello

    I had the same problem.

    If you go into the power settings (right click on the battery icon), select additional power settings and change the power plan that you use.  The brightness slider is the wrong way autour if you selected it to its maximum intensity is in fact completely black.  Move the cursor to the other end and save the settings (nothing will happen as long as you save the settings).  The reason it's ok on battery is that the cursor is somewhere in the middle.

    I hope this helps.

    See you soon

  • White screen and beeps when turn on Satellite 3000 X 11

    Can anyone help? A couple of times in recent weeks my Satellite 3000 X 11 itself has turned off. However, it then displays a white screen when I turn it on and 3 beeps followed by 3 beeps of x x. The power led & battery lights on and the hard drive flashes once - fan does not work - it happened to someone else? Or can someone suggust cause and remedy? Thank you
    Tim

    HI Edward,.

    Beep codes are indications that the unit doesn't have his POST processing. The exact cause can only be diagnosed by a qualified Toshiba service agent.

    In regards to your hard drive, will find it this located below your optical drive that must be removed first. Remove the screw (F5) the appliance and slide the optical drive before that. You will then be able to access the hard disk.

    Kind regards

  • Satellite A350 - white screen of death

    Hello

    Recently, I broke my screen in a fit of anger and sent him to Toshiba repair.
    They replaced my screen. It was a month ago.

    I installed windows 7 3-4 days ago and it worked fine.
    I opened my laptop one night to discover a white screen empty.
    After turning it works, take the battery and the white screen remained, and then it appeared randomly with system restore options

    I restored the system and apply a fix from microsoft to counter the supposed error windows 7. It did not work.
    White screen when I put the laptop to sleep (the laptop stop) or stop it.

    The screen appeared again yesterday and I left it all night in the hope that this would change.
    My sister took out and put back in the battery and a screen appeared asking how you would like to start windows.
    I started windows then reinstalled Windows Vista using a mirosoft installation disc.

    After the installation of AVG Antivirus it tells me to restart.
    I restarted the laptop and instead of the toshiba logo on the white screen of death appeared.
    He stayed for 10-20 seconds then my laptop started.

    I looked at this article (http://www.laptoprepair101.com/laptop/2008/04/13/laptop-lcd-screen-turned-white/) and suggested that the screen may have problems. I should send it back to Toshiba?
    Can someone provide diagnostics?

    My specs:
    Intel Core 2 Duo CPU P7450 processor
    2.13 ghz
    4.00 GB RAM
    32 bit OS

    So basically, I have a white screen randomly when I reboot, turn on, or put the laptop to sleep. If he get's a strange thing to many factors. I don't think that its my OS because what happens on Vista and Windows 7

    Please help as much as you can. I didn't wan't to take it in for repair as it can cost money

    Hello

    For me, it looks like hardware problem.
    It s hard to tell if it s graphic card issue or display problem.
    But if the display has been replaced a month ago, then I would recommend contacting the guys again. I mean the part could be faulty again and my knowledge, replaced parts are covered by warranty for a short time then perhaps that the warranty would cover it once again if the display is faulty

  • HP G72-259wm: white screen

    I have a white screen when I start my HP G72. The fan works and the lights on the keyboard work. I tried the hard reset without the battery and still nothing. I would like to connect the computer to my TV to see if that works but you read the settings in the Control Panel must be modified to work. I'm stuck now and I would be grateful some advice. Thank you.

    Basically, I wonder how I would go about changing the settings on the computer to work with the tv when I see nothing on the screen of the computer. Does not appear that it would be possible for me.

  • White screen satellite C650 - no Boot Up

    Satellite C650 - no Boot Up - white screen

    This laptop is just over 1 year.

    Laptop screen suddenly went white, he is stopped even if the battery was half full.

    It will charge is no longer and the charging light does not illuminate.

    Does not respond when you press the power button, even using from the mains.

    Is it a common problem with this model?

    It is possible to address the question, what are the steps involved in the process?

    Laptop needs spare parts to fix this?

    Thank you.

    > Is it a common problem with this model?
    Certainly not and something like this can happen on every laptop.
    On this virtual path, it is not easy to say what problem can be. All of a sudden switch OFF may be related to material high temperature and overheating.
    I put t know how I can you use your laptop on battery power, but I hope you don t use it in the lap or bed and the air vents are not blocked somehow.

    Place the laptop on the desktop and check if the same thing will happen again.

    When the laptop turns off and you leave it for a while, can you restart normally?

    I have restored the defaults in the Bios, but it didn't work.

    Please help me

    You see the Toshiba start screen at the beginning of the boot process?

    I searched this forum for the same problem on M70 but I found nothing didn t.

    But I do remember that one of my friends had a similar question. If the adapter has been unplugged the system locked and the screen is dark.
    It has fixed in powerplay disable in the ATI graphics settings and it didn't put the CPU low speed in Toshiba Power saver mode fixed.

    But like I said this happened only together running the operating system without the AC adapter.
