简介

转到步骤 1 ↓

Use this guide to replace the USB board in your HP 15-fc0000 series laptop. The only replaceable USB board is on the right side of the laptop, near the DC-in port, and holds one USB-A port.

Note: This procedure was written using a model 15-fc0093dx HP 15 Laptop PC but is compatible with any HP 15 Laptop PC whose model number starts with 15-fc.

This procedure requires removing the battery to disconnect it. Use care to avoid bending, twisting, or puncturing it—a charged lithium-ion battery can be very dangerous if accidentally punctured. If your battery looks puffy or swollen, take extra precautions.

4. 步骤 11 Remove the battery
  Do not grab the battery at the ends because this battery is flexible. Instead, grab the battery one inch from each end to better support the middle.
  
  Use two hands to grip the battery about one inch from each end.
  
  Lift the front of the battery (the side closest to you) until the battery is free of its alignment pegs.
  
  Pull the battery towards you to release it from its connector.
  
  Don't continue to use a damaged battery, as doing so is a potential safety hazard. If in doubt, replace it with a new battery.
  
  During reassembly, insert the battery onto its connector at a slight downward angle before pressing it flat to the frame.
