Windows 10: Processing light lights up on computer idle

my computer light lights up when processing or loading things, but when i play music and leave my pc idle, the light lights up as if it is loading something until i start to move my mouse or press a button on my keyboard it then stops, why is it doing that?

:)

 

Keyboard lights

1. Did you mean the keyboard backlight or indicator lights (i.e. Num Lock)?
2. If your problem is about indicator lights, are you using a external keyboard?

--KEYBOARD BACKLIGHT--

Consult your laptop's manual downloaded from the internet. You might want to install some drivers in order to use the backlight.

--INDICATOR LIGHT--

1. LAPTOP KEYBOARD
   • If indicator light, try pressing the Caps Lock key and see if the caps lock light turned on. Same process for Scroll and Num lock.
   • Some laptops may show the "Caps Lock ON" in your laptop screen.
2. EXTERNAL KEYBOARD (EITHER USB OR BLUETOOTH)
   • When you use the external keyboard, locate the "Caps Lock" key indicator light. Try pressing the "Caps Lock" and make sure if it is turned on. Same process for Scroll and Num Lock.

If these are not working, try installing or updating the drivers. You'll need to restart after installing.

No Night Light

Hi allisonb1

Try these steps

Option 1. Reset Night Light-related Settings on Windows 10 Fall Creators Update

If you find the night light in the Action Center or the Settings is greyed out after the Windows 10 Fall Creators Update, you can fix it with the steps below:

Step 1. Use Windows shortcut keys Win + i to open Settings.

Step 2. Go to the Privacy menu.

Step 3. On the left side, choose the Location tab.

Step 4. Click the Change button under the Location for this device.

Step 5. Toggle the switch under the Location for this device to ON.

Step 6. Toggle the switch under the Location service to ON.

Step 7. Restart the computer.

Now check the Action Center or the Settings on your Windows 10 Fall Creators Update to see if the night light feature is available.

Option 2 . Modify Registry to Fix Night Light Not Working on Windows 10 Fall Creators Update

If the methods above didn't work, you may need to modify the registry to fix the greyed-out night light button or the night light not working issue. Note: Windows Registry is a vital database on Windows OS computer. Any misoperation will cause server system
problems, such as 100% disk usage issue, blue screen issue, endless reboot, etc. So it's important to backup registry before the changes.

Now let's kill the night light not working and release the pain:

Step 1. Use Windows shortcut keys Win + R to launch Run.

Step 2. Type into regedit.

Step 3. Hit the Enter key.

Step 4. Copy and paste the path into the address bar of the Registry Editor: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount

Step 5. Press the Enter key.

Step 6. Right-click the key $$windows.data.bluelightreduction.bluelightreductionstate under the DefaultAccount and select the Delete to remove it.

Step 7. Right-click the key $$windows.data.bluelightreduction.settings and select the Delete.

Step 8. Restart the computer.

Then you can go to the Action Center or the Windows Settings. The night light not working issue has been resolved now and the night light button is available.
