Dell Latitude 10 ST2: Screen very dark after the Windows Update 8.1 & gameplay of Diablo 2

Hello community,

I just got a new Latitude 10 ST2, and I really appreciated the help until after that I updated for Windows 8.1 and played some Diablo 2. For some reason, my brightness is now always very low, regardless of whether the Adaptive brightness in my power management setting is enabled or disabled. I can manually change the brightness, but it has very little effect. It seems that the maximum brightness is really low for a reason any.

I don't know if Diablo 2 has nothing to do with this problem, but I though that I would include it here because it uses very outdated graphics techniques that seem not very compatible with Windows 8.1. I had to change the compatibility settings of the game executable for Windows XP Service Pack 2, force them to run with 16-bit colors and also to disable the composition of the bureau. After closing the game, icons on the desktop still seemed a little wide (they looked rather 16-bit color and had some weird artifacts) and I had to restart the tablet to correct. After the reboot of the Tablet, the desktop icons were back to normal, but my light issues began to arrive.

My first attempt at solving this problem was in the shape of the tablet. I used my USB stick that has the factory settings on it to format the Tablet and reinstall Windows 8. The process was a success, and I had no problem of brightness either. However, after the update to Windows 8.1, then by restarting the Tablet, my issue with the brightness came back.

My second attempt was to try to update my drivers. I ran the auto updater provided with the Tablet, and it updated my BIOS. Unfortunately, it has not fixed the problem at all. Then, I took a look in the BIOS and found levels of brightness in the video section. The parameters are the following:

Brightness on battery: 7
Brightness of AC: 15

I've tried corresponding to the brightness of the battery at 15, but it has no effect. The light problems don't occur that the Tablet is connected to a power outlet or not, I wasn't really that surprised that it didn't work. A maximum brightness of 15 is normal? (what is a percentage?) I don't want to change these settings without knowing exactly what they represent to avoid damage.

My third attempt has updated the chipset drivers which includes the video driver. I installed the chipset driver and suddenly after that the screen went black a few times during the installation of the brightness has been completely restored and colors looked nice and bright again. However, when I rebooted the Tablet I found that the problems of brightness was back. Very rarely when I restart the Tablet, the brightness is normal again, but it is super rare. A subsequent reboot simply results in brightness problems return immediately.

A few other things worth noting that come with the light problems:
-All color gradients are not smooth. You can very clearly see the differences in brightness when a picture goes to a light color to a dark like a lot of buttons in Windows 8 start menu. It reminds me a lot of 16-bit color;
-Whenever I try to change the display settings in the Intel Graphics and Media Control Panel, nothing happens. No matter how much I fiddle with the brightness, contrast or gamma, nothing changes, even after you apply the settings.
-Diagnostic in the BIOS tests said that everything is OK;
-The complete diagnosis provided by the PC Dell Diagnostics program showed that each test passed successfully.

I really hope that someone can help me with this problem. The screen is also very dark, it makes it quite difficult to use tablet. Thank you!

Kind regards

Thanks for the reply! After much trial and error, I discovered that my graphics driver has been be corrupted by AVG 2014 somehow. After yet another format and reinstall of Windows 8, but without AVG 2014 this time, everything works great! : D

    Hello

    I have a HP G62-b05SD. I noticed that many people have the problem of simmular.

    I know what makes, but don't know how to fix it.

    So here it is.

    Sometimes when I boot / reboot system screen turns black after the windows logo, but if I wait a while, I do not hear the star tune up windows, but the screen remains black.

    I noticed that this happens when I shut down or restart the system with a usb port (be it a mouse or a stick is not serious)

    If I all out en usb port restart or turn on the machine for the first time this day here, everything starts well.

  • Latitude D610 screen turns off after the Windows XP loading screen

    I'm having a problem with my Latitude D610 where after the Windows XP loading screen, the screen turns off completely. No BSOD, no login screen, just a white screen. This started happening at least a year, however, I bought a new computer if it is passed to the hatch. I tried the system restore when it appeared first without success. The computer starts in Mode safe. Any suggestions?

    If it starts in mode without failure, then its almost certainly a driver and with the blank screen problem, I suspect a display driver.

  • My Dell Latitude Tablet is stuck on 'Failure to configure Windows updates from reinstatement of changes' (Windows 8)

    It was stuck on this during about 3 hours and I desperately need to use... It is essentially new from today, as I had mail. I really don't understand why this is happening and I can't find a way to fix.

    From what Ive seen in similar forums, that I'll post things that do not work in my situation.

    • I don't have any sort of keyboard or mouse for this tablet.
    • I tried to restart the flight button and button / stop
    • I took the battery.
    • I do not have a more 8 GB USB so I can't use a recovery.

    Honestly, I'm so frustrated because I both want and need to use it for school... I don't have the time and money to run around to try to find a larger USB... at least not for a few days or a week. If no indication as to what is wrong and all the other options would be very appreciated.

    Hi Alex,

    I understand the inconvenience caused to you due to this problem. Installation of Windows Update takes this long period. It seems to be a problem with the Windows Update components. You could also face this problem at any time update does not install correctly and it is not to let any other updates to settle.

    As you mentioned that this is a new feature by Dell I suggest you contact the manufacturer or point of purchase. You can contact the Dell forums on the information provided below.

  • By default Firefox screen fonts distorted after the last update.

    I got the update for Firefox 33.0.3 the other day, and since the 'default' screen fonts are not the same. Text various (on her "ask your question... ("support page I am on now, for example) a registration that is weak or appear"broken ". When I open the same page in Internet Explorer, it looks very good. Any ideas, please?

    Hey, I found it... and fixed it! Windows has a feature called Clear of Type technology. Their description is a bit vague; of course, it's a kind of liaison between Windows and the graphics controller. Someone on another forum mentioned clear Type part of an independent issue, so in desperation I followed his instructions and found the "secret switch. Of course, it was transformed into 'off' (a "normative", actually), and once I lit it all now seems just the way it did a few days ago. My K & E 'Drafting Table green' always came not with Firefox, but it is normal; at least I can read the text now.

  • Start up hangs before login in screen after the Windows updated 10/26/2010

    Before going to bed, I decided to install all Windows Update after they have been downloaded (don't know what they are).  I do not download anything at night or for the past weeks.

    Yesterday, I went to turn on my laptop and it could be block/gel just before the log on screen and after departure upward. My pointer doesn't move or anything.  Graphics seem to have stopped and remained black with only the pointer that appears.

    I decided to do a reboot to safemode (all 3) and it hangs at ahcix64.sys.  I also tried a recovery back to a month ago and it would be dismissed. (don't remember error number, but will update when I'm back on what it was).

    I tried to use KNOPPIX to get all my fails, and which also failed during startup.  I would rather a restore of the entire system.  Please let me know if this happens to you.

    I downloaded the 14 updates (15/12/2011) and 2 were for Outlook and 2 for Microsoft Office. When I try and load a MS Office 2007 program, it takes about 10 to 15 seconds. When I try and load MS Outlook it takes about 10-15 seconds, but when I try to go to Inbox to a different folder or calendar or Contacts it takes 20 to 25 seconds before anything appears. This happens just after I downloaded the latest updates. It was beautiful before.

  • Satellite L10 screen very dark after disassembly

    Hi all

    I took my Satellite L10 part to swap on the plastic dessu for a damaged joint.
    Now is superb, but something was wrong as the screen is not be enlightened now.

    Anyone have any suggestions what else could be?

    If I look at the screen to light, I can see the desktop, I bought a new UPS thinking that was the problem but it has not fixed it :(

    Maybe a second faulty inverter? I checked all connections etc...

    Thanks in advance!

    Rich

    Hello

    For me, this looks like the inverter issue.
    If you see the desktop and the image appears as behind a thick mist, then in most cases this problem is related to the inverter FL.

    I put t know if the inverter is faulty or if you have connected all the bad parts
    The two may be possible, and so I recommend you to speak with a local laptop technician.
    In your case, that the old parts must be checked first, before buying a new FL inverter, cable, etc.

    See you soon
