H236HL monitors do not keep brightness settings

I have purchaced a bunch of monitors with our new computers Lenovo M73Tiny H236HL.  The tiny M73 are DisplayPort, so I use a DP to HDMI cable.

I sent 2 of these systems so far and they both have the same problem: after 2 minutes after loggin, two systems back to the brightness level 0.

I'll go into the settings and manually adjust the brightness up to 70% of return and it will stick... until you log in again.

Windows 7 64-bit, the H236HL is in the Device Manager.

Is this a problem with the HDMI on these monitors?

AH-HA!  Found!

Windows doesn't have a power function to the bottom of the brightness of the screen... BECAUSE OF LENOVO.

Apparently, it was a feature buried in Lenovo Power Manager control.  Once I dug this program - buried in another program - I found that the default power level has changed the brightness to 0.  I created a new profile of power and stimulated only the screen brightness setting... TA DA!

  • Firefox will not keep the settings available, they keep coming back to a default value

    I used to be able to change the zoom by using ctrl_scroll and it worked fine (to fit the entire page on a single screen with no scroll bar). Now, even after I have it, as soon as I go to a new site or edit folders in gmail, it keep coming back to a default zoom make the page too big to fit on a single screen. It is especially annoying with gmail...

    There are a couple of modules designed to record your zoom settings. They also allow you to define a new zoom level for all pages, you have not yet visited. I have not tried, but here they are:

  • Why Firefox will not keep my settings? I need to reset all my settings each time I connect.

    Whenever disconnect me, close and restart. She finds the default settings that occur after a new installation of Firefox. It retains the settings, if I exit and restart Firefox without stop, but if I stop, he forgets everything.

    What security (firewall, antivirus) software do you have?

    Some security software has virtualization or sandbox features that can cause problems to protect and restore files in the Firefox profile folder.

    I am trying to install a pc health check-up for my laptop but it says my monitor does not have the minimum required display settings and change the default DPI level.  How do I do that?

    What version of Windows?  You can change the DPI on Windows XP but right click on your desktop, choose Properties, selecting the tab settings, clicking on advanced and change the dropdown to DPI.  Other versions of Windows have similar steps.

  • Canon imageFORMULA DR - 3080CII USB Scanners do not keep settings

    We have five of these scanners.  We have recently upgraded to Windows 7 throughout the Organization and had some unexpected problems with this scanner since the upgrade.  Scan for the scanner Panel does not retain its settings of the scanner if you change between 24-bit grayscale and black and white.  When you try to change it, he returns to the default value.  Same thing with the brightness and other settings.  You can try to change any setting and after you make the change, then it returns instantly back to the default setting.

    We tried the upgrade and downgrade even driver versions.  This is not enough and uninstalling and reinstalling didn't help either.  I know that Canon has abandoned this model scanner and besides their support has never been that good, so even if they talk to you, the chances of a positive outcome are not good.

    Any advice?

  • All new Iphone 6s do not keep the load.

    I bought the new IPhone 6 s today two weeks ago. I'll have to charge at least twice per day, within a period of 10 hours. I was told when buying I could get 17 to 24 hours autonomy. I'm not running several apps and do not keep a bright screen.  How can this be repaired?

    Before he can be 'fixed', the question must be identified. Go to settings > farm and see which application uses the highest percentage of your battery. You will also need to look at this other parameters you turned on and determine how you use the device.

  • I've updated to Firefox 8, now, it will not keep Me connected to all the sites!

    Everything was beautiful and brilliant. Then I updated to Firefox 8. Now any website I want to (Amazon, Facebook, Twitter, etc.) will not keep me connected when I check the box to do so. As soon as I close Firefox and reopen it, I have to log in again, even if on some sites it's to remember my username and password (just do not keep me logged).

    I tried to delete all cookies and history and still nothing.

    Does anyone else have this problem?

    In the privacy section of the Firefox options, make sure that Firefox is configured to accept cookies and that it is not set to clear history of Firefox closing.

    (If you use the default "Remember history" then it should work fine. If you use the "customized for the history settings" setting, and then make sure that "Accept cookies" is checked and "clear history of Firefox closing is not checked.)

  • Impossible to add an external monitor or adjust the brightness of the screen: Pavilion dv7-4031TX (Windows 7)

    Hello

    I recently replaced both hard drives of HDD2K12, which meant I had to re-enstall Windows 7. Since that time, I have no options more in using an external monitor or even the brightness of the screen. The computer does not recognize the monitor when I Plug and all my drivers are up to date.

    Can you make suggestions that could help to solve these two problems?

    Kind regards

    Peter

    Thanks to find the links but I could not find the drivers I need for a Pavilion dv7-4031TX.

    However I finally managed to fix the problem. Let me summarize what has been my problem.

    (1) I could not adjust the brightness of the screen by using the function keys f2 and f3.

    (2) I couldn't find the brightness slider if it was generally... i.e. (control Panel\Hardware and Options of Sound\Power)

    (3) my laptop would not recognize an external monitor.

    How I solved the problem:

    1 > pass.

    http://h10025.www1.HP.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-95107-1 & CC = in the & DLC = in & LC = on & os = 4063 & Product = 4253423 & sw_lang =

    and go to the graphics driver and download the graphics driver and follow the directions. At the end of the installation you will be asked to restart the computer.

    0nce you have restarted your computer, you should be able to adjust the brightness of the screen using the fn keys or the brightness slider in the window 'power Option '.

    2 > Activting 2nd monitor

    Click on Device Manager... At start-> right click on 'Computer' and click 'properties '. Click on "Device Manager". Now click on "monitors".

    Now, right-click on it and select "update driver software... "then search automatically for updated drivers. Install the new drivers. You should see the generic 'PNP monitor' name change to another name.

    3 > restart your computer. You should find that after doing all this, you should be back to normal.

  • When the upgrade to Firefox 3.6 4, it will keep your settings, bookmarks, session Manager tabs, etc.?

    When the upgrade to Firefox 3.6 4, it will keep your settings, bookmarks, tabs/Session Manager settings, etc.?

    When updates to Firefox, it will use the profile folder existing (location where user data is stored). It's going to use you current bookmarks, use passwords, cookies and other data.

    During the upgrade, it will check your extensions and themes to see if they are compatible with Firefox 4. If they are not compatible with Firefox 4, it will offer to check updates and if none is found, it will disable the.

    Although not exhaustive, the following link shows the compatibility of many popular add-ons. Those listed as compatible with 4.0. * or more should work on Firefox 4 - https://addons.mozilla.org/en-US/firefox/compatibility/report

    help please

    Hello

    Usually, you can switch between the internal and external screen using FN + F5 key combination

    Try it! Perhaps out of the display is set to an external monitor only.

    But you see something on the internal display when the external monitor is NOT connected?
    Some image of the Toshiba start screen or the notes of the BIOS?

  • Satellite L650 - black on the monitor is not 100% black

    Hello
    first sorry my English is not good at 100%, but I'll try my best.

    I have a new Toshiba Satellite L650 and I see a little problem of color on the screen. When I turn on the computer, when the lights to light up the screen, black is not 100% black, its more like dark blue, not a lot, but I can see the diference. When comes to windows 7 still have same problem of color issue. I tried to calibrate colors, but they all up looks normal to me because I have to another (older) Toshiba and the colors are great, very good.

    I've updated the bios and graphics of the main card and still no improvement. I tried also calibrate the colors in the main graphics tools (ATI) and the problem persists. In addition, in games, the color doesn't seem 100% good.
    Can we say its problem of monitor?

    Hi, Flip,

    I put t know if it s a monitor problem or not, but you should test an external monitor to your laptop computer. In order to check if it s associated with internal monitor or not.

    In the settings of the display driver, you can adjust the colors. You need to test it with the default settings, instead all colors maximum.

  • HS SX60 - how long to keep the settings without main battery

    SX60 HS does not keep date/time settings and seems other setting too when the main battery is taken out for charging. How long camera must retain parameters without main battery? I sent the unit for repair, had refirbished with the same problem - memory loss.

    Should I continue to send the camera for repair under warranty until Canon will do something reasonable? Or return the money for that camera?

    The internal date and time battery should load up in 4 hours with a charged battery installed. Then it must retain the date and time for about 3 weeks once loaded and the battery removed.

    If this is not done or pretty close to that, then by all means send it back for repair or replacement or refund.

    To my knowledge, that is not a chronic problem with the SX60 so in all liklihood, you have a faulty they need repair.

  • The monitor does not display the entire desktop - having to move the mouse to see the corners of the screen.

    A part of the image on the monitor is not visible. It's as if I'm able to display an image 13 "on a 15 or 17 inch screen. The top and sides of the screen are not visible unless I move the mouse to the sides or the top or bottom. It's as if the computer is set to magnify the mode. Thank you in advance for any ideas you may have.

  • Monitor does not return after sleep.

    When my computer is in sleep mode and I come back to it, the monitor does not.  A message stating that he'll be back in the mode 'sleep', and the only way I can get to come is to manually restart the computer by holding the power button flashes.  The problem seems to get progressively worse - sometimes taking a quite awhile to come back even after rebooting.  I disconnected and then reconnected all the plug-ins and that you have completed all the recent Norton checks available to me.  Any ideas on why it is past, or better yet, how to fix?
