Portege Z830 - backlight of the screen remains off after sleep

Hello guys!

As described in the topic, the display backlight remains always off when my PT225E z830 returns from sleep mode. It's the only backlight, because I can see the image weakly if I have the screen against a light. Also using FN + F7 does not alter this State. The only thing that works is to restart.

Y at - it an update of the display driver? Or is there any workaround to get back the backlight of the screen?
Moreover, the bios is up-to-date with the version v1.60.

Thanks for the reply!

Hello

Have you noticed this problem on the first day of use, or later?
Have you changed anything, installed additional software or maybe your own version of the OS?

  • Satellite L670 - screen remains black after sleep mode

    I recently bought a L670. When I close the laptop, it goes into sleep mode. No problem with that. But when I opened the laptop again the screen remains black.
    I see on the drive activity light that the laptop come out of sleep mode correctly, but the screen remains black.

    I don't have this problem when the sleep mode is only a few minutes. Then the screen comes up correctly.
    But for example after an hour of sleep mode... no screen.

    I'm doing something wrong?

    Thanks in advance for your feedback.

  • Monitor may not turn off after setting the screen turns off after a period of inactivity

    Original title: control screen does not turn off

    My cell phone 6 year old runs today to Win XP Pro and IE7 and Firefox. My screen has been set to turn off after 15 minutes, but these days he keeps any. It stays ON all day.

    Attempted to solve by setting to turn off in 10 minutes, but it makes no difference, what could be the problem?

    TIA

    First of all, you don't want to do the hardware updates through the Microsoft Update Website.

    Secondly, there are a couple ways you can do this:

    1. go in the Device Manager (start > Control Panel > administrative tools > computer management > Device Manager).    tedious, but this way you are sure.

    Double-click each item, having developed each sign, select the driver tab and choose Update driver, let windows search automatically, make sure that you are connected to the internet.  Do this for each item that you want to search for updated drivers.

    2. go in the manufacturer's website. For example, I use a Dell Dimension and move the driver Dell downloads Web site.

    If you mean hardware upgrade from Microsoft (not Windows which is software) you would search Microsoft.com site for driver downloads.

    Hope this helps, after back with your results, please.

    I understand that you get a black screen after that it was closed automatically for automatic updates. It might be difficult when things don't work the way it should be on your computer. This problem might have occurred because of the conflicted with the system files update or could be a problem with the display card drivers may be due to the virus/malware infection.

  • Prevents the screen turn off (locked)

    The screen turns off after a short period, as configured in the settings. But sometimes this must be disabled by software, for example the navigation software should not leave the screen get black. (BlackBerry Maps seem to handle this...)

    There are other situations where it might be a good idea to leave the screen in Active mode, perhaps the media players (watch the video) and so on.

    The page settings of the device even informs me in the operative part of security/password on the fact, that applications could extend the time until that the device will be locked with password.

    But I can't find any documentation on how the two that can be made from code.

    What permission is needed and I have to call?

    Copy the following code prevents the lock screen:

  • Inspiron 9300 screen turns off after the Windows Logo screen

    Inspiron 9300 my wife became severely infected.  I thought I had some weird things start popping up of the problem decided to wipe the hard drive and start over.  Unfortunately, I don't have to restore disks when I bought the computer.  I install windows xp pro service pack 2 full retail version.

    Installation was not a problem until I installed the driver ATI Mobility x 300.  I followed directions for installation from the website, do the installation of xp followed of the dell system software update followed of chipset followed video driver.  After that whenever I put on, the screen turns off after the Windows Logo.  The computer is still running and if I plug an external monitor everythng is fine.

    I tried all the troubleshooting tips I've seen in this forum.  I did a full install twice. made of safety boots (all right), started in VGA mode (works fine), I ran diagnostics from fn on startup, including express, extended and video tests and they pass all the controls.  I'm sure it's a software problem, but have been unable to solve.  I've updated the ATI bios although when I run it says already installed and done one installs x 300 driver on 6 ttimes own.

    I know it must be something simple that I'm missing. My system is the Inspiron 9300 with 2 GB of ram and the mobility x 300 card.  Any help would be appreciated.

  • MacBook Pro 2015 turns on but the screen remains black...

    Hello

    Today, I tried to turn on my MacBook Pro, but my screen stays black. When I press the caps lock button, it turns green which I guess means he lit. I've also heard the startup chime it generally makes when you turn on. I already tried to turn it on and off several times and reset the SMC and the LANDAU... The screen is always black.

    Could someone help me please?

    Also a few minutes ago the fan has started to make noise in the macbook...

    But the screen remains black.

    Thank you

    Shaynidw

    Hi shaynidw,

    From your description, it seems that your MacBook Pro is powered, as soon as you hear the startup chime and see the light on the keyboard.  Thus, it seems that the problem may be with your screen or the video card.

    On the screens you see when you start your Mac

    Power on

    When you turn on your Mac, display is off (black) and you hear a startup chime. Your Mac Initializes his BootROM and memory (RAM live). It then performs a power - on that self test (POST) and a test of BootROM. If you hear beeps or chimes at this stage, this indicates a possible hardware problem and start stops. If you add memory to your Mac, check that it is installed correctly.

    White screen

    After that only walking self-test is completed, your Mac sends a video signal to your connected screens. The screen may appear black or grey at this point in the boot sequence and backlight of the screen should light up. If you do not see the image appears on your screen after a few moments, try increasing the brightness of your screen. If you use an external monitor, make sure it is properly connected and turned on.

    shaynidw, if set up the brightness of your screen does not help, you have an external display (computer screen or TV) that you can attach to your MacBook Pro to test?

    In addition, you can try to start your computer in safe mode to see if you get different results.

    Try safe mode if your Mac does not end commissioning

    If the problem persists, you may need to take your computer to an Apple Store or service provider authorized Apple , so they can inspect the video card and cables to isolate the problem.

    Take care.

  • 32L3441DG - bright green but the screen remains black

  • No backlight on the screen of the Satellite A200 - 14 d

    Hello!

    Since yesterday I have a problem with my Toshiba Satellite A200 - 14 d. I left my laptop in full of energy and on the current for a while (about 30-40 min). When I got home, it was in standby mode (I'm with XP, btw). I pressed a key on the keyboard to exit this state of power, but all of a sudden the screen blinked, half of it went dark, then the other is too much and that's it. I thought it may have overheated or something like that, even if it was lit for an hour or less... I turned it off using THE button, left for about 15 minutes cool down a bit... After that I turned it on, but it's the same thing. While the Toshiba logo was displayed, the screen does the same thing and it went dark... But what I've noticed ofter an hour invesitgating, that he was not completely black. I thougth the display is off, but when I took the my lamp office and turned on the screen I was surprised to find, that I could see my office and the other stuff. Very dark, but everything was visible, even I was able to read things with black letters on white background... But when I turned off the light, everything was dark again... I tried to run some programs and everything works great - no problems at all except that I could not see most of the things that have happened to the screen.

    I searched with Google and I found the same description of my problem in a site for laptop repairs. Here, the author says that it is a very common problem by books and it was because of what we call "FL inverter Board" or something like that, which is responsible for the backlight of the screen. Whitout the backlight, you can see a very bleak picture of your office, bootscreen etc.

    My question is - what would I do? I am with an international warranty and I'm in Germany now (I have not bought the laptop of the Germany). I've heard of the hotline and a courier who comes and takes your laptop and need to service... Can someone explain to me step by step what I'm supposed to do?

    Thanks in advance!

    PS: Sorry for my English.

    Hello

    He aren´t much the steps - you have an international guarantee and that is enough.
