Introduction

Is your wifi running incredibly slow or not connecting at all? If your laptop is the only device having problems, then replacing your wireless card may help.

What you need

1. Step 1 Battery
  Working on your device while it is turned on may result in electric shock. Make sure to shut down and unplug your device before you begin.
  
  Flip your device over so the bottom panel is facing up.

2. Step 2
  The battery is held in by a latch in the front and tabs in the back.
  
  Slide the lock switch left, towards the center of the computer.
  
  Lift up the battery, rotating it up and away from you, then pull it out.
  
  To put the battery back in, line it up with the battery bay and the holes for the tabs. Then let the battery rotate towards you and press down until the latch engages and you hear a click.
