Removing The Compute Node Cover - Lenovo Flex System x440 Compute Node Installation And Service Manual

CAUTION:
When replacing the lithium battery, use only Part Number 33F8354 or an equivalent type battery
recommended by the manufacturer. If your system has a module containing a lithium battery, replace
it only with the same module type made by the same manufacturer. The battery contains lithium and
can explode if not properly used, handled, or disposed of. Do not:
• Throw or immerse into water
• Heat to more than 100° C (212° F)
• Repair or disassemble
Dispose of the battery as required by local ordinances or regulations.
Attention: Touching the CMOS battery on a metal surface, such as the side of the compute node, when you
replace the CMOS battery can cause it to fail.
To install a CMOS battery, complete the following steps:
Step 1. Remove the cover (see
Step 2. Follow any special handling and installation instructions that come with the CMOS battery.
Step 3. Locate the CMOS battery socket on the system board (see

Step 4. Orient the CMOS battery so that the positive (+) side faces in toward the center of the compute
node.
Step 5. Pivot the CMOS battery so that you can insert it into the bottom of the socket.
Step 6. As you slide the CMOS battery into place, press the top of the CMOS battery into the socket.
Step 7. If you removed a cover from the battery, replace the cover.
After you install the CMOS battery, complete the following steps:
1. Install the cover onto the compute node (see
instructions).
2. Install the compute node into the chassis (see
instructions).
3. Turn on the compute node, start the Setup utility, and reset the configuration (see
