In this guide I show how to disassemble Lenovo ideapad Flex 5-1470 (models 81C9, 80XA) or Lenovo ideapad Flex 5-1570 (models 80XB, 81CA). I will walk you through the step-by-step process of all internal components removal.
Flex 5-1470 and Flex 5-1570 models are almost identical besides the screen size and the base size. You can use this guide if you want to upgrade the laptop, replace failed components or simply clean up from dust.
I’ll be using only three basic tools during the disassembly process: Phillips #1 screwdriver, fine tweezers and case opener tool.
Base cover and battery removal
Remove 10 screws located on the bottom of the laptop.
Separate the bottom cover from the top case assembly using a case opener tool.
Pry the bottom cover up to disengage hidden latches holding the cover in place.
Remove the bottom cover completely.
Remove two screws securing the battery.
