Method and system for conserving power and improving usability for personal computers with remote startup features
First Claim
1. A method for remotely powering up a computer, comprising the steps of:
- (a) receiving a telephone call by a device coupled to a powered down computer;
(b) determining an originator'"'"'s telephone number for the telephone call;
(c) generating a wake signal by the modem to a Basic Input/Output System (BIOS) of the computer;
(d) comparing the originator'"'"'s telephone number with a plurality of authorized telephone numbers by the BIOS; and
(e) powering up the computer if the originator'"'"'s telephone number matches one of the plurality of authorized telephone numbers.

Abstract
A method for remotely powering up a computer, includes: receiving a telephone call by a device coupled to a powered down computer; determining an originator'"'"'s telephone number for the telephone call; determining if the originator'"'"'s telephone number matches one of a plurality of authorized telephone numbers; and powering up the computer if the originator'"'"'s telephone number matches one of the plurality of authorized telephone numbers. The method and system utilizes the well known “Caller-ID” technology to determine the originator'"'"'s telephone number for a telephone call received by a modem coupled to the computer. If there is no match, the computer remains in a powered down state. In this manner, the system discriminates between the received telephone calls, and avoids powering up the computer when the received call is not for this purpose. This avoids wasting power.

12. A system, comprising:
-
a powered down computer, wherein the computer comprises a BIOS; and
a modem coupled to the powered down computer for receiving a telephone call, wherein the modem comprises;
a caller ID controller for determining an originator'"'"'s telephone number for the telephone call, and a PCI register space, wherein the originator'"'"'s telephone number is stored in the PCI register space, wherein the modem generates a wake signal to the BIOS when the model receives the telephone call, wherein the BIOS determines if the originator'"'"'s telephone number matches one of a plurality of authorized telephone numbers, wherein the BIOS powers up the computer if the originator'"'"'s telephone number matches one of the plurality of authorized telephone numbers.
