Replacing The Battery - Lenovo 10A2 User Manual

Replacing the battery

Attention:
Do not open your computer or attempt any repair before reading and understanding the "Important safety information"
on page v.
Your computer has a special type of memory that maintains the date, time, and settings for built-in features,
such as parallel-port assignments (configuration). A battery keeps this information active when you turn
off the computer.
The battery normally requires no charging or maintenance throughout its life; however, no battery lasts
forever. If the battery fails, the date, time, and configuration information (including passwords) are lost. An
error message is displayed when you turn on the computer.
Refer to the "Lithium coin cell battery notice" in the Safety, Warranty, and Setup Guide that came with your
computer for information about replacing and disposing of the battery.
To replace the battery, do the following:
1. Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect
all power cords from electrical outlets and disconnect all cables that are connected to the computer.
2. Remove the computer cover. See "Removing the computer cover" on page 36.
3. Remove the heat sink fan duct. See "Replacing the heat sink and fan assembly" on page 65.
4. Depending on your computer model, you might need to remove the PCI Express x16 graphics card for
easier access to the battery. See "Installing or replacing a PCI card" on page 38.
5. Remove the old battery.
