Keyboard backlit W540 always lit

Is it possible to adjust the backlight on the keypad to always on when the screen is opened?

I don't think it's as simple as changing a value. The scale of the retro-lighting/thinklight seems to be in very low-level keyboard routines, which are almost certainly in the BIOS code itself. This would mean that the current state is not recorded anywhere, or stored in the CMOS memory. Because it is longer between boots, I guess that's registered anywhere.

  • CPU round ends, but my keyboard lights are always on.

    It seems that your computer is overheating or video card is a failure.

    http://www.elephantboycomputers.com/page2.html#Hardware_Tshoot

    On tests of hardware failures often alleged swapping parts by parts checked. If you can not do the test yourself and/or are uncomfortable opening your computer, take the machine to a professional computer repair shop (not your local equivalent of BigComputerStore/GeekSquad). If possible, have all your data backed up before taking the machine into a shop. MS - MVP - Elephant Boy computers - don't panic!

  • BlackBerry smartphones when I charge the phone, the keyboard and the screen is always lit

    I have 2 problems, the first is that when I load the phone screen and kaey pad are always as I {m using the phone, the screen never gets dark, what's wrong with my phone? what can I do?}

    The second problem is with my battery when I charge the phone it last me only 1 day and it supposed to last 9 days standby according to the specifications of the phone, I recharged during the night and in the morning with no use to 90% and it is last up to half of the day.

    I'm not sure of the backlight staying on during the load, but on the second issue, you have probably some applications running in the background.

    Remove the battery and restart the device, see how it keeps the burden.

  • ENVY 17 t-J100 Leap Motion: keyboard backlit ENVY 17 t-J100 Leap Motion edition shuts down after each power down.

    My brother has an ENVY 17 t-J000 Quad Edition. Only about 6 months. Its backlit keyboard remembers its state of on or off when it reboots or off. When he turns on his laptop back, the keyboard is always if it's him on when he turned off the laptop.

    I just got the ENVY 17 t-J100 Leap Motion backilt keyboard edition. But every time that I reboot or shutdown with the backlight on, it is turned off when I have the laptop or reset. So whenever I have to re - turn on the backlight. Very annoying.

    Anyone else with the jump movement 17 t-J100 having this problem? If so, I hope it's fixed soon. I also can't update the Nvidia drivers then perhaps we need a BIOS update to solve these two problems.

    I just checked to be sure. It turns off if the laptop is turned off and turned on then again - but if I just restart the kbd is running.

  • Keyboard backlit S50 - B - 15 p of satellite does not

    Hello..

    I have model S50 - B - 15 p with 10 Windows installed. I never checked if the backlit keyboard worked on Windows 8.1, as soon as I got it I have upgraded to Windows 10.

    I have installed all the drivers for the Toshiba Windows 10 upgrade page but as before, the keyboard works just not backlit.
    I opened the software utility eco and checked for the backlit keyboard at eco mode settings, however there is no and no parameters exist in BIOS either. The keyboard has the symbol to activate backlit button Z however by pressing FN + Z does nothing.

    Does anyone have any ideas on how to solve this problem? T the same keyboard not this function, or is defective?

    Thanks, Craig

    I have the same problem as its with you
    my laptop is Satellite S50T-B1391, which is again just 4 days, I check every thing like you Fn + Z does not work the bios is the new version and nothing is there also nothing backlit in eco utility app

    I check in victory 8.1 before the upgrade and earn 10 all have the same problem

  • Keyboard backlit on Satellite C660

    Greetings.

    I recently bought a Satellite C660, but now I would like to know if it is possible to replace the standard keyboard by an illuminated. A backlit keyboard won't work because she needs some kind of a power supply for LED? Toshiba sells such component individually?

    Egert

    These updates is not possible.
    Backlit keyboard needs supply and must be connected to the small port on the motherboard. If your card mother doesn t have there is therefore no chance to use the backlit keyboard.

    I'm sorry.

  • Satellite P750-13F - how to activate the keyboard backlit on Windows 8

    Hello!

    Today, I installed Windows 8 premium on my P750-13F, which features a backlit keyboard. In order to upgrade to Windows 8 I had to uninstall certain Toshiba drivers and other programs.

    Now, I have fully functional Windows 8, but I don't know how to access the functions of FN key (screen brightness, wifi power button, volume up/down).

    Now that the FN key is innoperative function that I miss the most is that for illumination of the keyboard, because I can still do everything else by other methods (I mean volume up/down, brightness etc) but I don't know how to illuminate the keyboard now.

    I tried to install the Toshiba hardware configuration utility, but it will not install with Windows 8. I like so much if the FN key remains innoperative (although that would be nice if it would not) but what I really want to be able to change the lighting of the keypad.

    I'll be very grateful for any ideas.

    Up to Toshiba doesn t offer Win8 tools and utility there is nothing you can do about it. I hope that will happen very soon.
    So please be patient until the stuff of Win8 will be offered for download.

  • Zbook 15: 15 Zbook replace keyboard backlit version

    I have a 15 a standard keyboard #745663-001 Zbook G1, and I want to replace it with the version backlit #733688-001.

    No problem with that? I don't see a different number for the motherboard with a backlit keyboard, so I guess my motherboard will accept it. Are there changes that should be made to the bios or whatever it is necessary to do this?

    All the world did this with success?

    I answered my own question and write here for the benefit of all.

    Short answer: NO, you can't replace a no backlit keyboard with the spare of backlit 15 Zbook.

    The motherboard does not the connected device.

    I have the manual maintenance and then disassembled the computer.

    The backlit keyboard (as indicated in the service manual) has 3 cables towards 3 connectors on the motherboard.

    My (non-clavier backlit) has 2 cables going to 2 connectors on the motherboard. There is no connector 3rd on my motherboard.
