1 Hard disk drive or solid state drive
Your computer may have a large-capacity, customer-upgradable hard disk drive that can meet a variety
of storage demands. To keep the data on your drive safe, Active Protection System™ is installed on your
computer. For details, refer to “Active Protection System” on page 19.
With Lenovo technologies advancing to provide you with the best engineered systems, some models
are equipped with a solid state drive for data storage. This cutting-edge technology enables notebook
computers to be lighter and faster.
Note: The hidden service partition is the reason why there is less free space than expected on your hard
disk drive.
2 Emergency reset hole
If your computer stops responding and you cannot turn it off by pressing the power switch, remove the ac
power adapter and reset the computer by inserting a needle or a straightened paper clip into the emergency
reset hole to turn off the computer.
3 Slice battery connector
By installing a slice battery you can extend the operating time of the computer. For more information, refer to
“ThinkPad Battery 39+ (6-cell slice battery)” on page 93.
Slice batteries are available as options and you can purchase one from Lenovo. See “Finding ThinkPad
options” on page 93.
4 Fan
The internal fan and louvers enable air to circulate in the computer and cool the central processor.
