Component Features
The following sections contain brief descriptions of the notebook’s internal hardware.
Primary Battery
Each notebook is equipped with a rechargeable, non-replaceable, primary Lithium Polymer
(Li-Poly) battery. The NEC UltraLite notebook uses a 12-cell battery. The NEC DayLite SVGA
reflective notebook uses a 12-cell battery. The NEC DayLite XGA transflective notebook uses a
9-cell battery. The primary battery is built into the back of the LCD panel.
Secondary Battery
A removable secondary Li-Ion 3-cell battery is installed in the battery bay to help prevent data
loss. An optional Extra Life Li-Ion battery can be installed in the battery bay in place of the
standard secondary battery.
CMOS Battery
The lithium CMOS battery on the main board provides battery backup and prevents data loss in
the system's complementary metal oxide semiconductor (CMOS) RAM. This memory area
contains information on the system's configuration, for example date, time, drives, and memory.
The CMOS battery charges when the notebook is connected to AC power. The CMOS battery
may discharge completely if the notebook remains unused for approximately two months.
Hard Drive
A standard 2.5-inch, 9.5 mm hard drive ships with the system.
