Introdução
Follow this guide to replace a worn-out or dead battery in your Logitech MX Keys Mini wireless keyboard.
It’s natural for batteries to lose capacity as they age. If your keyboard dies quickly and doesn't hold a charge, it may be time to replace the battery.
For safety, perform this repair when your battery is below 15% charge. Any charged lithium-ion battery can be hazardous if punctured or damaged. If your battery looks puffy or swollen, take appropriate precautions.
-
-
Slide the keyboard's power switch into the OFF position.
-
Unplug all cables from your keyboard.
-
Lay your keyboard down with the feet facing up on a clean work surface.
-
-
-
Insert the point of a spudger under an end of the foot.
-
Push the spudger underneath the foot and lift until you can grip it with your fingers.
-
Peel the foot up and remove it.
-
Repeat the process to remove the top right foot.
-
-
-
Use a pair of angled tweezers to peel up and remove all the plastic film from the foot recesses.
-
If you're installing new feet, remove them from their backing and firmly press them into place.
-
If you're reusing the feet, use a strip of double-sided tape to secure them in their recesses.
-
-
-
Use the pointed end of a spudger to poke through each film so you can access the screw underneath.
-
-
-
Insert an opening pick between the battery cover and keyboard.
-
Slide the pick along the top and bottom edges to release the clips.
-
-
-
Remove the battery cover.
-
Place the battery cover onto the keyboard assembly so the screw holes line up with their posts.
-
Press down firmly along the battery cover to engage its clips.
-
-
-
Use a pair of angled tweezers to firmly grip the battery connector and slide it straight out of its socket.
-
Insert the connector into its socket so the side with raised plastic in the center is facing up.
-
Push on the edges of the connector with the flat end of a spudger until it's fully seated in the socket.
-
-
-
Insert the flat end of a spudger underneath the right edge of the battery, opposite the cables.
-
Slide the spudger underneath the battery and gently lift to separate the adhesive securing it to the keyboard.
-
Remove the battery.
-
-
-
Remove any bits of the old adhesive from the battery recess.
-
If your replacement battery doesn't come with tape pre-installed, apply double-sided tape to the battery recess (not directly to the battery).
-
If your replacement battery has adhesive pre-installed, remove the plastic liner.
-
Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.
To reassemble your device, follow the above steps in reverse order.
