Windows 10: Help! Backlit keyboard remains on when computer is powered off despite device manager settings.

My ThinkCenter M720s running Win11 has 8 USB slots, 4 in the back and 4 in the front. I have the keyboard & mouse plugged into the back along with a portable hard drive. Device manager has the following listed:1st: Intel USB 3.1 eXtensible Host Controller - 1.10 Microsoft and is set to allow computer to turn off device to save power.2nd: USB Composite Device and there is no power management option.3rd & 4th are USB Mass Storage Device, but I only have one external harddrive plugged in. Maybe the other is the LG DVD player that is plugged in. Both have power management set to computer

keyboard backlite

Hi Carmine,

If your device has a backlit/backlight keyboard, there is usually a special key on it to turn the light on and off. Just to ensure that we'll arrive at a proper resolution, we'd like to get answers to the following questions:

• May we know the make and model of the device that you're using? Also, please indicate if you're having difficulties turning it back due to a recent software update or changes made on your computer.
• Have you checked your device manufacturer's user guide to verify if there's a function key or a BIOS setting to disable/enable the keyboard backlight?

 

backlit keyboard and calculator problem

Bree,

I attempted the BIOS edit again. Here are the details:

• Mouse cursor is not available. All navigation is via arrows and F (function) keys. (My other Dell has the mouse feature.)
• There is no GENERAL tab; rather there is a MAIN tab.
• There is no + for expand or contract the menu.
• Using the down arrow, I cannot navigate beyond system date.
• Checking all the other tabs revealed no keyboard related options.
• on the MAIN tab keyboard is indicating backlite.

Additionally I searched for driver updates using Windows update, Device Manager search for newer driver versions, and the manufacturer's web site and found that I have the latest version. In Device Manager uninstalling keyboard driver and rebooting resulted in no change.

What next?

 

Mouse/touch pad and keyboard wakes laptop up and power management tab missing?

Hi,

Welcome to Microsoft Community.

As per the description, I understand that you are trying to disable keyboard and touchpad to wake the computer from sleep.

As you are missing the Power Management tab in driver properties, I suggest you to follow the steps provided below and update the keyboard and touchpad drivers.

To update keyboard drivers,

• Press Windows key + X and select Device Manager from the list.
• Expand ‘Keyboard’ from the list.
• Right click on the driver and select ‘update driver software’.
• Follow the on-screen prompts to update the driver.

To update touchpad drivers,

• Type Device Manager in the Search box and press Enter.
• Expand Mice and other pointing devices.
• Right Click on the driver and select Update Driver Software.
• Follow the on-screen prompts to update the driver.

Hope this helps. Keep us posted on the status for further assistance.
