Chassis Foot Removal; Removing The Battery - NEC POWERMATE ES 5200 Service Manual

A – Battery
The battery can explode if it is incorrectly replaced or
improperly discarded. Use only the same battery or an
equivalent type recommended by the manufacturer when
replacing the battery.
Lithium acts as a catalyst when exposed to water and
causes spontaneous combustion on contact. Discard used
batteries according to the manufacturer's instructions.
7. Reverse the previous steps to install a new battery.
8. After the system reassembled and restarted, run CMOS Setup Utility to
reconfigure system parameters (see Section 2, "System Configuration").

Chassis Foot Removal

The minitower chassis has two feet that are designed to prevent the system unit
from tipping. Keep the feet turned out unless you are upgrading or repairing the
system.
The right chassis foot is longer than the left chassis foot to distribute the weight
of the system unit components evenly. The right chassis foot lock (a disk that is
clipped to the chassis floor and secured with screws) has different tabs than
those on the left chassis foot lock.
Remove the chassis feet as follows.
1. Turn off the system and disconnect the system power cord.
2. Ensure that all external cables are disconnected from the front and rear of
the system.
3. Remove the left system unit cover (see "Removing the Minitower Side
Covers").
