Computer system in which a high-order application program recognizes a power-on factor or a state of an expansion unit
First Claim
1. A computer system comprising:
- a timer configured to store current date information, current time information alarm date information and alarm time information, and output a timer signal when the current time information and the alarm time information coincide with each other, the alarm time information and the alarm date information being set by an operator, the timer signal indicating that the timer triggers a power ON for necessary components in the computer system;
register configured to store the timer signal; and
a control section formed of a program configured to read out the current date information and the alarm date information from the timer and compare the current data information and the alarm date information in response to storage of the timer signal to said register, and execute power-ON processing when the current date information and the alarm date information coincide with each other.

Abstract
A computer system is provided has a computer main body and an expansion unit to be attached to and detached from the computer main body. Power is input to the computer system in accordance with a plurality of factors. A power supply controller determines which factor has caused power-ON for the computer system, and writes the result of this determination into a power-ON factor register. BIOS reads the content stored in the power-ON factor register and executes processing in accordance with power-ON factors. Before the computer system is switched on, the power supply controller determines the connection, type and state of the expansion unit and writes the result of this into the state register. BIOS executes error processing, etc., in accordance with the content of the state register.
