Circuit and method for remote diagnosis of personal computers
First Claim
1. A method of remotely diagnosing faults on a personal computer, comprising the steps of:
- confirming an existence and a proper operation of a modem coupled to said personal computer, said step of confirming performed in a central processing unit (CPU) of said personal computer and in a diagnostic environment independent of a normal operating system of said personal computer;
receiving an indication of a selection of diagnostic routines to be performed from a remote location via said modem; and
performing selected ones of said diagnostic routines as a function of said selection.

Abstract
Disclosed are a circuit and method for remote diagnosis of personal computers. The method comprises the steps of (1) confirming an existence and a proper operation of a modem coupled to the personal computer, the step of confirming performed in a central processing unit ("CPU") of the personal computer and in a diagnostic environment independent of a normal operating system of the personal computer, (2) receiving an indication of a selection of diagnostic routines to be performed from a remote location via the modem and (3) performing selected ones of the diagnostic routines as a function of the selection. The present invention allows an experienced technician located remotely from the computer to interact as though seated in front of it, to thereby allow remote diagnosis of even critical faults that prevent the computer from booting.

15. A method of remotely diagnosing faults on a personal computer, comprising the steps of:
-
executing a diagnostic operating environment, said diagnostic operating environment independent of a normal operating system of said personal computer and capable of visually communicating information pertaining to diagnostics of said personal computer to a user; executing an initial diagnostic routine, said initial diagnostic routine performing tests on a central processing unit (CPU) and other selected core components within said personal computer; confirming an existence and a proper operation of a modem coupled to said personal computer; locally presenting, via said diagnostic operating environment, a list of options for further diagnostic routines to be executed, one of said options being remote diagnosis; remotely presenting, via said diagnostic operating environment and said modem, said list of options; receiving an indication of a selection of diagnostic routines to be performed from a remote location via said modem; performing selected ones of said diagnostic routines as a function of said selection; and remotely presenting, via said diagnostic operating environment and said modem, information pertaining to execution of said selected ones of said diagnostic routines. - View Dependent Claims (16, 17, 18)

19. A system for remote diagnosis of a personal computer, comprising:
-
non-volatile memory within said personal computer containing a diagnostic operating environment, said diagnostic operating environment independent of a normal operating system of said personal computer and capable of visually communicating information pertaining to diagnostics of said personal computer to a user; a central processing unit (CPU) coupled to said non-volatile memory and capable of executing an initial diagnostic routine, said initial diagnostic routine performing tests on said CPU and other selected core components within said personal computer, said initial diagnostic routine further confirming an existence and a proper operation of a modem coupled to said personal computer; a display device capable of locally presenting, via said diagnostic operating environment, a list of options for further diagnostic routines to be executed, one of said options being remote diagnosis; and a remote link including said modem and capable of remotely presenting, via said diagnostic operating environment, said list of options, said diagnostic operating environment receiving an indication of a selection of diagnostic routines to be performed from a remote location via said modem, said CPU performing selected ones of said diagnostic routines as a function of said selection, said diagnostic operating environment remotely presenting, via said diagnostic operating environment and said modem, information pertaining to execution of said selected ones of said diagnostic routines. - View Dependent Claims (20, 21, 22)
