Lenovo Tab S8 Motherboard Replacement

Step 1 Battery



• Make sure the device is powered off.
• Gently insert a spudger into one of the bottom corners between the screen and body case.
• Slide the spudger along the inside of the crack in order to pry the case open.
• Be careful of the small volume and power buttons when prying the case with the spudger. They are connected with small pieces of plastic that break easily.

• After removing the cover, remove the M1.6 x 2 mm screw from the battery cable with the JIS J000 screwdriver.
• Using screwdriver bits that do not fit in the screw head might strip the screw and render it unusable.
• Remove the tape by gently scraping the edges up with the spudger.
