Label side facing down
When attaching your computer to the port replicator, do not attempt to insert or remove the battery pack. Lifting and turning the computer with a port replicator attached could cause a temporary loss of power.
The computer automatically charges the battery (the battery indicator light flashes in a double-blink pattern as the battery charges). When the battery is 85 percent full, the battery indicator light turns off. This process takes approximately two hours. To charge the battery completely, continue charging for an additional hour. See Displaying Detailed Battery Information in the online document

Notebook User Guide
To determine the amount of time the battery lasts, see Displaying Battery Information in the online manual Customizing Your VAIO® Notebook. When the battery power is running low, both the battery and power indicators blink. When the computer is directly connected to AC power and has a battery pack in the battery bay, it uses power from the AC outlet. See Using a Second Battery Pack on page 35 for information on installing and charging a battery pack in the multipurpose drive bay. Keep the battery pack in the computer while it is directly connected to AC power. The battery pack continues to charge while you are using the computer. If the battery level falls below 10%, you should either attach the AC adapter to recharge the battery or shut down your computer and insert a fully charged battery. You can extend battery life by changing the power-management modes in the PowerPanel utility. See Using Power Saving Modes on page 33. The battery pack supplied with your computer is a lithium ion battery and can be recharged at any time. Charging a partially discharged battery does not affect battery life. The battery indicator light is on while you use the battery pack as a power source. When battery life is nearly depleted, the battery indicator starts flashing. For some software applications and some peripheral devices, your computer may not enter System Hibernation mode when the battery life is low. To avoid loss of data when using battery power, you should save your data frequently and manually activate a power-management mode, such as System Suspend or System Hibernation.
To remove the battery pack
Open the cover of the battery bay.

Pull out the battery pack.

You may lose data if you remove the battery pack while the computer is on and not connected to the AC adapter or if you remove the battery while the computer is in System Suspend mode.

keypad area to type numbers or to perform mathematical calculations such as addition and subtraction. Note that you must press the Num Lock key to activate the numeric keypad. (When you do so, the Num
Lock light will be on.) Navigation keys Several keys are devoted to moving the cursor on the screen. Correction keys The Insert, Back Space, and Delete keys enable you to make
corrections in your documents. Function keys The twelve function keys along the top of the keyboard are used to
perform designated tasks. For example, in many applications, F1 is the
Help key. The task associated with each function key may vary from
one application to the next. Escape key The Esc (Escape) key is used to cancel commands. Print Screen key The Print Screen key takes an electronic snapshot of the screen and
places it in the Windows Clipboard. You can then paste the screen
shot into a document and print it.
