Keypads
You can do keypad work with your computer by using the keypad 
embedded in the computer keyboard or by connecting an optional 
external keypad. The keypad embedded in the computer keyboard 
is called the embedded numeric keypad.
The embedded numeric keypad cannot be used while an external 
numeric keypad is connected to the computer.
Using the Embedded Numeric Keypad
The embedded numeric keypad consists of 15 keys that can be 
used like the keys on an external numeric keypad. When the 
embedded numeric keypad is turned on, each keypad key 
performs the functions indicated by the icon in the upper-right 
corner of the key.

Switching the Functions of Keypad Keys
You can temporarily switch the functions of an embedded 
numeric keypad key between its standard function and its keypad 
function.
■To use a key on the keypad as a keypad key while the 
keypad
 is turned off, press and hold fn while pressing the key.
■To use a key on the keypad as a standard key while the 
keypad is turned on: 
❏Press and hold fn to type with the key in lowercase.
❏Press and hold fn+shift to type with the key in uppercase.
Releasing fn returns a keypad key to its set function. For example, 
a keypad key returns to its keypad function if the keypad is turned 
on or to its standard function if the keypad is turned off.
Using an External Numeric Keypad
✎The embedded numeric keypad cannot be used while an 
optional external numeric keypad is connected to the computer.
Most keys on most external numeric keypads function differently 
depending on whether num lock mode is on or off. For example:
■When num lock mode is on, most keypad keys type numbers.
■When num lock mode is off, most keypad keys function like 
the arrow, page up, or page down keys.

Selecting a Power Source
Use the following table to select a recommended power source 
for the way you plan to use the computer.

Connecting the AC Adapter
Å
WARNING: To reduce the risk of electric shock or damage to the 
equipment:
■Plug the power cord into an AC outlet that is easily accessible at all 
times.
■Disconnect power from the computer by unplugging the power cord 
from the AC outlet (not by unplugging the power cord from the 
computer).
■If provided with a 3-pin attachment plug on the power cord, plug 
the cord into a grounded (earthed) 3-pin outlet. Do not disable the 
power cord grounding pin; for example, by attaching a 2-pin 
adapter. The grounding pin is an important safety feature. It is 
possible to receive an electric shock from a system that is not 
properly grounded.
To connect the computer to external AC power:
1. Plug the AC adapter into the power connector 1 on the 
computer.
2. Plug the power cord into the AC adapter 2.
3. Plug the other end of the power cord into an AC outlet 3.

Switching Between Battery and 
External
 Power
The computer runs on external power whenever external power 
is
 available to the computer. This conserves the charge in an 
inserted battery pack. External power can be supplied through 
an
 AC adapter, an optional expansion product, or optional 
combination power adapter.
Because the computer switches between battery power and 
external power according to the availability of external power: 
■If the computer is running on battery power and you connect 
the computer to external power, the computer switches to 
external power. 
■If the computer is running on external power (and contains a 
charged battery pack) and you disconnect the computer from 
external power, the computer switches to battery power.
Displaying the Power Meter Icon
When the computer is running Windows, a Power Meter icon is 
displayed by default in the notification area, at the far right of the 
taskbar. The Power Meter icon changes shape whenever the 
power source changes between battery power and external power.
If the Power Meter icon is not displayed in the notification area 
when the
 computer is running Windows: 
1. Select Start > Control Panel > Performance and 
Maintenance
 > Power Options. 
2. Click the Advanced tab. 
3. Select the Always show icon on the taskbar check box. 
4. Click OK.
✎If you cannot see an icon you have placed in the notification 
area (at the far right of the taskbar), the icon may be hidden. 
Click the arrow in the notification area to view hidden icons.

memory (RAM), the screen is cleared, and the power lights blink. 
When you resume from standby, your work is returned to the 
screen where you left off. 
ÄCAUTION: To reduce the risk of information loss, save your work 
before initiating standby.
Hibernation
