issue to address for a regular system user. To help tech aspirants, we have

Keyboard not working issue. Make your technical
insights enhanced with this quick guide to resolve the backlight not working on
your MacBook.
How to Solve Backlight Not Working on a MacBook?
The Mac device itself can help you in tweaking the Mac keyboard
not working issue. Let us learn how we can do it manually.
Avoid the Light Sensor from Facing Bright Light Source
The light sensor is responsible for the functioning of your Mac
keyboard backlight. Make sure your light sensor is not facing any strong light
sources. A strong light on the keyboard may make the light invisible. Using
your MacBook in a dark area can resolve the issue with your Mac keyboard
backlight.
Check the Battery Level
Another possible reason for the keyboard backlight not working is
a low battery level. The MacBook is designed to turn off the keyboard backlight
when the battery level is low to conserve power.
Step 1: To check the battery
level, click on the Apple menu.
Step 2: Go for the ‘About This
Mac’ option.
Step 3: Click on the Battery tab.
If the battery level is extremely low, connect the MacBook to a power source to
charge it. You can also find the battery level indicator on the top right bar.
Check the Keyboard Connections
In some cases, the keyboard backlight may not work due to hardware
issues. It is essential to check the connections of the keyboard to ensure that
everything is in order. Disconnect the keyboard from the MacBook and reconnect
it after a few seconds. If the problem persists, try connecting a different
keyboard to see if the issue is with the keyboard or the MacBook.
Reset the System Management Controller (SMC)
The System Management Controller (SMC) is responsible for managing
several hardware functions on a MacBook including the keyboard backlight. A
corrupted SMC can result in various issues, including the keyboard backlight
not working.
Disable the Automatic Turn-Off Keyboard Backlight
Sometimes keeping the automatic option enabled can interrupt the
functionality of the Mac keyboard backlight. The auto light sensing ability of
your Mac keyboard may be the reason for this problem. Use the following tweaks
to ensure that you have not enabled the Auto-turn off option.
Step 1: Go to the Apple menu and
select System Settings.
Step 2: Scroll down and select the
keyboard in the slide bar.
Step 3: Drop down the “Turn
keyboard backlight off after inactivity” menu and select a time period to
automatically turn OFF the backlight after being inactive for the selected
time.
Step 4: If the above option is
selected, you can disable the Automatically turn off keyboard backlight.
Step 5: At the same time, you can
also disable the ‘Adjust keyboard brightness in low light’ option. This option
automatically adjusts the backlight brightness when you move to low-light
conditions.
Check whether the issue with your Mac keyboard has been resolved.

backlight. To resolve this issue, you can try disabling Power Saver Mode on
your Mac. Use the following tweaks to disable the Power Saver Mode on your Mac.
