System Board
The system board (G8TZL) is the primary component in the system. It contains I/O
subsystems and houses the Intel
®
486 DX4-75 chip (75 Mhz internal, 50 Mhz external).
The chip controls important functions including power management, direct drive bus
interface and memory management.
System board specifications are listed in Table Section 2-8 at the end of this section.
Battery Pack
The system uses a rechargeable lithium-ion (Li-ION) battery as its transient power source.
The battery pack installs in the compartment next to the diskette drive assembly. The
battery uses 14.4 volts with a 2700 mAh capacity.
The battery pack powers the Versa 2000 for up to approximately four hours under power
management, and two hours without power management. In addition, the battery pack lets
the user know how much battery power is available via the LEDs on the front of the
system, or the battery gas gauge in Windows.
When battery power is getting low, connect the AC adapter to a wall outlet and recharge
the battery. It takes 1.6 hours to recharge the battery pack when the system is powered off.
It takes 6 to 9 hours to recharge the battery while the system is powered on.
CMOS Battery
The lithium battery (3.6 Volts, 1000 mAh capacity) is connected to CN17A on the system
board. It 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 like date, time, drives, and memory. The CMOS battery lasts
approximately two years.
Bridge Battery
The bridge battery saves the memory contents and system status for up to 5 minutes while
in Suspend mode. It is connected to the system board via CN 13. The AC adapter maintains
voltage in the bridge battery when the system is powered on or off. The bridge battery
provides 10 Volts, 30 mAH.
PCMCIA Slots
The Versa 2000 provides a 3.3 volt interface for either two Type I/Type II PCMCIA cards,
or one Type III PCMCIA card.
