    I bought a Lenovo 50 80 g (it's under warranty). I'm having this problem with contrast/brightness of the built-in display. It is that it is too high (unacceptable), it is not natural and I can not yet able to fix is a problem or software drivers for hardware? Please guide me how to solve this problem.

    I think I've fixed this by right click on the desktop and choose Properties Intel graphics from there I went to the power Option and (in the menu dropdown) chosen on doughy and disabled Disable Power Saving Technology

    PS: in addition to this I adjusted also in contrast to 45 in the color settings.

  • The display brightness is automatically defined by content screen brightness?

    Additional for my other problem with the brightness of the screen I also have this question:

    Battery operation, it seems that the display brightness is automatically adjusted by the lightness of the contents of the screen.

    For example if I start a program with a dark background display becomes a little darker. On the other hand, a lighter background makes the screen a little clearer. It is not strong like a tap on F7 or F8 - just a little bit.

    Of course, this is a nice feature. But for me who use many applications as it is a bit annoying.

    Can someone give me a tip where I can disable this feature? Found nothing in the settings of the energy.

  • Satellite U840-10V - screen brightness problem

    Hello
    I own a U840-10V laptop and I have a little problem with my screen brightness from the first day I got it.
    The fn keys work correctly. When I press the button Fn + F2 or F3 I see small panel brightness adjustment, but values 1,2,3,5,6 and 7 (except 4) seem to have the same level of brightness (the 4th is darker).

    (I had problems with my backlit keyboard as well, but when I reset the defaults in the bios it worked perfect...)

    so is that what someone knows how can I fix?

    I reinstalled the PVAT to a newer version which was suitable for my laptop and windows7 - 64 bit, on the toshiba support site, but I haven't worked out.

    so if anyone can help me I would love...

    Thank you...

    It works correctly when you change the brightness level in the plan directly to settings?

    Hello

    You must install VAP and Support of Flash Card Utility for the FN keys works!
    Installation of VFR will not help you if you should not install Flash memory card Support utility.

    As far as I know, these two tools are not phone specific, so you can choose the VAP and the published Flash card for example utility for Satellite L500!

    I did it on my laptop and it worked fine!

  • Set the screen brightness Satellite Pro 4200

    Hello
    I heard a key combination that makes possible the setting screen brightness.
    Is this true and what is the key combination?

    Yours sincerely
    Riedlz

    Hi Daniel,.

    Normal for thie keys Fn + F7 to increase brightness and Fn + F6 to decrease. But the different laptop models use different key combinations, so I would check your user manual to see which ones is correct for your laptop.

  • Power supply Lenovo G50-80

    Hello

    I have laptop Lenovo G50-80.

    I have to turn off the power once the battery is charged to 100%?

    Please notify.

    Rizvi says:

    Thanks for this tip, but my question is still there...

    Do I have to unplug the charger once the battery is full 100%?

    I apologize if I wasn't clear...

    Do not disconnect AC when it is full, but it's a good idea to do so, then recconect when your laptop says that it needs.

    Leaving plugged power could potentially shorten the battery life and require optimization several times yet so if you hold a routine "disconnect when necessary.
