`A method for performing remote diagnostics on a per
`sonal computer ‘system in which the user calls a help
`desk representatlve who creates a computerized case
`?le which includes modem telephone numbers, call and
`computer identi?cation information. The representative
`also selects speci?c diagnostic tests, resident on the
`user’s diagnostic disk, to be run on the user’s computer.
`The representative creates a batch job which causes a
`computer to connect to the user’s computer via modem
`and instructs the user’s computer to perform the se
`lected tests. The telephone connection is then broken.
`The user’s computer reconnects with the help desk
`computer on completion of the tests and reports the
`result to the help desk representative. The representa
`tive then reviews the ?les and calls the user with recom
`rnendations. Certain necessary ?les can then be down

`SUMMARY OF THE PRESENT INVENTION

`
`BACKGROUND OF THE INVENTION
`1. Field of the Invention
`The present invention relates to a system for perform
`ing computer diagnostic tests, and more particularly, to
`a method for automatically performing remote diagnos
`tic tests on personal computers.
`2. State of the Related Art
`Personal computers have been used in an increasing
`number of business, home and recreational applications.
`Personal computer systems have also increased in their
`complexity and diversity. The average personal com
`puter user, while having a working understanding of
`their speci?c applications and, perhaps, a basic working
`knowledge of the computer system itself, is generally
`unfamiliar with the hardware design, operating systems
`and computer system con?guration. When a computer
`fails to operate in the manner expected, the user is often
`unable to determine the source of the problem or the
`necessary corrective action. The user may attempt to
`address the problem utilizing various diagnostic pro
`grams and manuals supplied by the computer manufac
`turer. However, it will be appreciated that much of the
`information contained within the diagnostic programs
`and manuals is often beyond the understanding of the
`average user. Further, the user may be unable to discern
`the import of the various test results.
`When faced with this problem, the user may call the
`computer manufacturer’s customer service line or help
`desk in an effort to obtain technical help. This generally
`entails calling a help desk and leaving a recording of the
`user’s name and telephone number. A help desk repre
`sentative then calls the user back and records informa
`tion concerning the user, the type of computer and
`attempts to determine the nature of the problem based
`on information provided by the user. The representative
`generally instructs the user to perform various diagnos
`tic tests over the phone and the user describes the re
`sults of such tests to the representative. The representa
`tive may also attempt to emulate the problem on his
`own computer in an effort to determine the nature of
`45
`the problem.
`This process is often slow and unsatisfactory. The
`amount of time required for the user to accurately de
`scribe the problem to the help desk representative is
`often considerable. Further, the process of the represen
`tative instructing the user to perform various diagnostic
`tests or corrective action is time consuming. It is also
`frequently plagued by inaccurate instructions being
`conveyed to the user over the phone. The process of the
`user reporting the results of diagnostic tests to the rep
`resentative over the phone may likewise be plagued
`with communications errors.
`One means of speeding up this process is the use of
`remote diagnostic services. Remote computer diagnos
`tic services are well known in mainframe computer
`applications. The user calls a customer service represen
`tative and explains the nature of the problem. The rep
`resentative then dials into the user’s computer via a
`modem and attempts to resolve the user’s problems
`while logged onto the user’s system. While this gives
`the representative a better opportunity to assess the
`user’s problem, it will be appreciated that this level of
`service is also time consuming. Moreover, this type of
`
`35
`
`. The present invention is directed to a method for
`performing remote diagnostic tests on a personal com
`puter system. In the preferred method according to the
`present invention, a user calls the customer service help
`desk and the call is routed to a customer service repre
`sentative. The customer service representative calls up
`an application on his or her computer to create a com
`puterized case ?le which includes, among other items,
`user identi?cation information, the user’s computer
`system identi?cation, the user’s modem telephone num
`ber and the help desk modern number. The user is then
`asked to identify the general nature of the problem.
`Based on the user’s explanation of the problem, the
`representative selects various diagnostic tests from a
`menu to be run on the user’s computer. The representa
`tive can specify the number of times each test is to be
`performed, as well as the name of log ?les to be created
`when running the tests. The test selection information is
`used to build a high level instruction or script ?le. The
`script file is associated with the case ?le by a database
`manager application. The help desk representative then
`instructs the user, upon completion of the telephone
`call, to insert a diagnostic disk, supplied to the user upon
`purchase of the computer, into the computer and initi
`ate a program which places the user computer’s modem
`in an auto answer mode. The help desk representative
`then terminates the call.
`The representative then submits the case and script
`?les to the database manager which creates a service
`job. The database manager then schedules the job to be
`acted on by a communications link manager application.
`The link manager application dials the user’s modem
`number, which is in the case ?le, and establishes com
`munications with the user’s system. The link manager
`then downloads the case and script ?les to the user’s
`computer. The user computer then terminates commu
`nications with the link manager.
`The diagnostic program running on the user’s com
`puter then initiates execution of the script ?le. The
`script ?le instructs the computer to execute selected test
`?les resident on the user’s diagnostic disk. The script ?le
`also speci?es the creation of various log ?les which
`record the results of the tests. Upon completion of all of
`the test programs speci?ed in the script ?le, the diagnos
`tic program will cause the user’s computer to reset.
`Following reset, the diagnostic program will instruct
`the user’s computer to dial the link manager task using
`the modem number provided in the case ?le. Upon
`establishment of communications, the link manager will
`perform a security check by interrogating the user’s
`computer for the case ?le identi?er. If the user com
`puter does not respond with a valid case ?le identi?er,
`the link manager will terminate communications. If a
`valid case ?le identi?er is received by the link manager,
`the user’s computer transmits the case, script and newly
`created log ?les to the link manager. The diagnostics
`program running on the user’s computer will also in
`struct the user’s computer to delete all copies of the
`down-loaded case, script and generated log ?les from
`memory. The user’s computer then terminates commu
`nications with the help desk communications manager.
`The link manager noti?es the database manager
`which, in turn, noti?es the help desk application and the
`representative that the diagnostic tests have completed.

`vice a greater number of service calls in less time.
`second target computer 90 is also shown as being con
`nected to the network 80. It will be appreciated that
`there are many other possible user U site con?gurations.
`The user U site may be a single computer 70 equipped
`with a modem 60. Alternatively, the target computer 90
`requiring diagnostic service may not be equipped with a
`modem 60 or attached to a network 80. In this instance,
`remote data communications would be between the
`computer 70 and the help desk link manager computer
`30. Files would then stored on removable storage media
`for transfer to the second computer 90. The method of p
`the present invention makes provisions for the above
`possibilities at the user U site.
`FIGS. 2A-2C are ?ow diagrams depicting the
`method of the preferred embodiment. Operation of the
`method begins at step 100. Logical ?ow proceeds to
`step 102, wherein the user U calls the help desk. The
`help desk telephone number is generally provided to the
`user U upon purchase of the user’s computer 70 or 90.
`Logical ?ow transfers to step 104, wherein the user’s
`call is routed to a help desk representative R. Logical
`?ow transfers to step 106, wherein the representative R
`creates a computerized case ?le. In the preferred em
`' bodiment, the help desk computer 10 is running a task
`which permits the representative R to set up a ?le
`which includes a unique case identi?cation number, the
`user’s identification, the user’s computer 70 or 90 identi
`?cation information, the customer’s modem number and
`the help desk’s remote communications modem number
`to permit the user’s computer 70 to dial in to the multi
`line modem 50. Some of this information, such as the
`user’s computer modem 60 telephone number and the
`user’s computer identi?cation information is provided
`to the representative R by user U, while other informa
`tion, such as the unique case identi?cation number and
`the help desk’s remote communications modem number
`are automatically provided by the task on the help desk
`computer 10. Logical ?ow proceeds to step 108,
`wherein the representative R, based on information
`provided by the user U, selects speci?c diagnostic tests
`to be performed on the user’s computer 70.
`The diagnostic tests may include tests directed
`toward printers, network cards, video systems, various
`input devices, various disk con?gurations, serial and
`parallel ports, tape systems, memory, processors and
`CD ROM systems. These tests are generally resident on
`the user’s diagnostic disk, but may be downloaded from
`the help desk for operation on the user’s computer 70.
`The representative R may specify that all tests or any
`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENT
`The present invention is intended to be used primarily
`in the realm of personal computers. The method of the
`present invention requires a number of preconditions.
`First, the user has access to a computer having a tele
`phone modem capability and knows the help desk tele
`phone number. Second, the user has access to the com
`puter manufacturer’s diagnostic disk(s) for the com
`puter.
`The diagnostic disk within the present invention in
`cludes standard diagnostic or test programs that may be
`45
`run by the user or within the method of the preferred
`embodiment. The diagnostic disk also includes program
`code which permits the user’s computer to read and
`translate a script ?le. While the preferred embodiment
`of the present invention utilizes standard diagnostic
`tests, it is contemplated that the diagnostic disk could
`include custom diagnostic test code for use within the
`method of the present invention. Further, it is contem
`plated that the script ?le could include custom diagnos
`tic tests downloaded with the script ?le.
`55
`FIG. 1 is a block diagram of an illustrative hardware
`environment in which the method of the present inven
`tion may be practiced. A user U experiences problems
`on computer 70 and is unable to resolve the problem
`utilizing the technical manuals or diagnostic programs
`60
`provided by the computer manufacturer. The user U
`calls a help desk representative R for aid in resolving
`the problem. The help desk telephone number is gener
`ally supplied by the computer manufacturer upon pur
`chase of the computer. The help desk may be part of the
`65
`computer manufacturer’s service organization or may
`be run by a separate company which has been con
`tracted to provide this service.
