Step 1. Prepare the Computer.  
 

CAUTION: Make sure the 

computer is turned off, the lid is 
closed, and the AC Adapter is 
disconnected. Failure to do so can 
result in damage to the computer. 
  
Place the computer upside down on 
a protected surface with the front 
edge facing you. 

Step 2. Remove the Battery Pack.  
 

Locate the release tab as shown in 
the picture. With your thumbs, push 
the tab in the release direction and 
gently lift up the battery pack. 

Step 3. Remove completely the 
battery pack from the computer and 
set aside. 

These easy instructions are intended to guide you through the replacement process.  
 

To avoid electric shock please make sure product is turned off and AC Adaptor is disconnected 
from the power source. Remove jewelry before you begin work to avoid scratching the surface of 

your notebook computer.* 

 

Place your notebook computer on a clean, stable and covered surface to avoid damage to the 
computer's case.

 

Follow the ESD (Electrostatic Discharge) damage prevention instructions: 

o

 

Hold parts by the edges, away from exposed circuitry when possible. 

o

 

Do not walk around excessively as this promotes static build-up. 

 

The appearance of the electronic components shown in the illustrations may be different from the 
components shipped. This slight difference does not affect the accuracy of these instructions.  

 

* Sony is not responsible for any loss of data associated with your computer or any damage caused by incorrect 
handling of the computer under these procedures. The terms of your Sony Limited Warranty continue to apply.
