Labels for the Windows operating systems
Windows 7 Certificate of Authenticity: Computer models preinstalled with the Windows 7 operating
system have a Certificate of Authenticity label affixed to the computer cover or inside the battery
compartment. The Certificate of Authenticity is your indication that the computer is licensed for a Windows 7
product and is preinstalled with a Windows 7 genuine version. In some cases, an earlier Windows version
might be preinstalled under the terms of the Windows 7 Professional license downgrade rights. Printed on
the Certificate of Authenticity is the Windows 7 version for which the computer is licensed and the Product
ID. The Product ID is important in case you need to reinstall the Windows 7 operating system from a source
other than a Lenovo product recovery disc set.
Windows 10 Genuine Microsoft® label: Depending on your geographic location, the date when your
computer was manufactured, and the version of Windows 10 that is preinstalled, your computer might have a
Genuine Microsoft label affixed to its cover. See http://www.microsoft.com/en-us/howtotell/Hardware.aspx
for illustrations of the various types of Genuine Microsoft labels.
• In the People’s Republic of China, the Genuine Microsoft label is required on all computer models
preinstalled with any version of Windows 10.
• In other countries and regions, the Genuine Microsoft label is required only on computer models licensed
for Windows 10 Pro.
The absence of a Genuine Microsoft label does not indicate that the preinstalled Windows version is not
genuine. For details on how to tell whether your preinstalled Windows product is genuine, refer to the
information provided by Microsoft at http://www.microsoft.com/en-us/howtotell/default.aspx.
Unlike Windows 7 products, there are no external, visual indicators of the Product ID or Windows version for
which the computer is licensed. Instead, the Product ID is recorded in the computer firmware. Whenever
a Windows 10 product is installed, the installation program checks the computer firmware for a valid,
matching Product ID to complete the activation.
In some cases, an earlier Windows version might be preinstalled under the terms of the Windows 10 Pro
license downgrade rights.

Access Connections™
(Windows 7)
The Access Connections program is a connectivity assistant program for
creating and managing location profiles. Each location profile stores all the
network and Internet configuration settings needed for connecting to a network
infrastructure from a specific location such as a home or an office.

The internal storage drive is less vulnerable to damage when it is not operating.
This is because when the internal storage drive is not operating, the system
stops it from spinning, and might also move the read and write heads of the

Power management
This section provides information about how to use ac power and battery power to achieve the best balance
between performance and power management.
Using the ac power adapter
The power to run your computer can come either from the battery or from ac power. While you use ac
power, the batteries charge automatically.
Your computer comes with an ac power adapter and a power cord.
• ac power adapter: Converts ac power for notebook computer use.
28
ThinkPad P70 User Guide
• Power cord: Connects the ac outlet and the ac power adapter.
Connecting the ac power adapter
To connect the computer to ac power, do the following:
Attention: Using an improper power cord might severely damage your computer.
Note: Ensure that you perform the actions in the following order:
1. Connect the power cord to the ac power adapter.
2. Connect the ac power adapter to the power connector of the computer.
3. Connect the power cord to an electrical outlet.
Tips on using the ac power adapter
• When the ac power adapter is not in use, disconnect it from the electrical outlet.
• Do not bind the power cord tightly around the ac power adapter transformer pack when it is connected to
the transformer.
Using the battery
When you use your computer away from electrical outlets, you depend on battery power to keep your
computer running. Different computer components consume power at different rates. The more you use the
power-intensive components, the faster you consume battery power.
Spend more time unplugged with ThinkPad batteries. Mobility has revolutionized business by enabling you
to take your work wherever you go. With ThinkPad batteries, you are able to work longer without being tied
to an electrical outlet.
Checking the battery status
Move your pointer to the battery-status icon in the Windows notification area to check the battery status.
The battery-status icon displays the percentage of battery power remaining and how long you can use
your computer before you must charge the battery.
The rate at which you use battery power determines how long you can use the battery of your computer
between charges. Because each computer user has different habits and needs, it is difficult to predict how
long a battery charge lasts. There are two main factors:
• How much energy is stored in the battery when you begin to work.
• The way you use your computer. For example:
– How often do you access the storage drive.
– How bright do you make the computer display.
Chapter 2. Using your computer 29
– How often do you use the wireless feature.
Enabling the battery alarm on the Windows 7 operating system
For the Windows 7 operating system, you can program your computer so that when the battery power falls
below a certain level, three events occur: the alarm goes off, a message is displayed, and the LCD is
turned off.
To enable the battery alarm, do the following:
1. Start the Power Manager program.
2. Click the Global Power Settings tab.
3. For Low battery alarm or Critically low battery alarm, set the percentage of the power level and set
the action.
Note: If your computer enters sleep or hibernation mode when the battery power is low without the alarm
message, the message is displayed when the computer resumes. To resume normal operation, when the
message is displayed, click OK.
Charging the removable battery
When you find that the remaining battery power is low, charge your battery or replace the battery with a
charged battery.
If an ac outlet is convenient, connect the computer to ac power. The battery is fully charged in about
four to eight hours. The actual charging time depends on the battery size, the physical environment, and
whether you are using the computer. You can check the battery charging status at any time through the
battery status icon in the Windows notification area.
Note: To maximize the life of the battery, the computer does not start recharging the battery if the remaining
power is greater than 95%.
Tips on charging the removable battery
• Before you charge the battery, make sure that the temperature is lower than 10°C (50°F).
• Charge the battery in any of the following conditions:
– A new battery is installed.
– The percentage of power remaining is low.
– The battery has not been used for a long time.
Maximizing the battery life
To maximize the life of the battery, do the following:
• Use the battery until the charge is depleted.
• Recharge the battery completely before using it. You can see whether the battery is fully charged from the
battery status icon in the Windows notification area.
• Always use power management features such as power-saving modes.
Handling the battery
This system supports only batteries specially designed for this specific system and manufactured by Lenovo
or an authorized builder. The system does not support unauthorized batteries or batteries designed for
other systems. If an unauthorized battery or a battery designed for another system is installed, the system
does not charge.
30
ThinkPad P70 User Guide
Attention: Lenovo has no responsibility for the performance or safety of unauthorized batteries, and
provides no warranties for failures or damage arising out of their use.
Note: If an unauthorized battery is installed, the following message is displayed: “The battery installed is
not supported by this system and will not charge. Please replace the battery with the correct Lenovo
battery for this system.”
DANGER
Do not attempt to disassemble or modify the battery.
Attempting to do so can cause an explosion, or liquid leakage from th
