Attention
The term Reserved describes certain signals, bits, and registers
that should not be changed. Use of reserved areas can cause
compatibility problems, loss of data, or permanent damage to the
hardware. When the contents of a register are changed, the
state of the reserved bits must be preserved. When possible,
read the register first and change only the bits that must be
changed.

Description
The IBM Personal System/2 Hardware Interface Technical Reference
describes devices common to the PS/2* AT-bus system family.
The IBM ThinkPad 560/560E computer (hereafter called the 560,
ThinkPad computer , or computer ) is a notebook-size computer that
features the AT* bus architecture. Each computer supports one
external diskette drive and one internal hard disk drive.
Programs can distinguish the foregoing models of computers from
other ThinkPad models by reading the system ID: Interrupt 15H,
function code (AH)=23H, (AL)=10H, returns (AL)=0EH for the
560/560E.
The system microprocessor contains an internal cache and cache
controller.
Figure 1-1 lists the model bytes, submodel bytes, and system clock
speed of the system board.

Power Supply
The power supply converts the ac voltage to dc voltage and provides
power for the following:
System board set
Diskette drive
Hard disk drive
Auxiliary devices
Keyboard
LCD panel
PCMCIA cards
Voltages
The power supply generates five different dc voltages: VCCCPU,
VCC3A, VCC5M, VCCSW, and VCC12M. Figure 1-8 shows the
maximum current for each voltage.

ThinkPad 560/560E System Overview 1-11

Output Protection
A short circuit placed on any dc output (between outputs or between
an output and a dc return) latches all dc outputs into a shutdown
state, with no hazardous condition to the power supply.
If an overvoltage fault occurs in the power supply, the power supply
latches all dc outputs into a shutdown state before any output
exceeds 135% of the nominal value of the power supply.
Voltage Sequencing
When power is turned on, the output voltages reach their operational
voltages within 2 seconds.
Power Supply Connector
The following connector is used with the AC Adapter. The total
power capacity of this connector must not exceed 4.0 A.
