A remote maintenance device for monitoring and controlling a host computer and its operating system. The device is fully independent of the host computer's hardware and peripherals (including local power, network, and telephony) and fully independent of the host operating system. The remote maintenance device uses a wireless modem (GSM) or wireless IP (packet) interface to provide commands from a remote technician to the remote maintenance device. The wireless communication link also transfers data to a remote technician who can then diagnose problems. The host computer may be reset and the power toggled on and off without affecting the maintenance-device's operation because of an onboard battery. The maintenance devices accesses the host's operating system and BIOS via serial ports, I2C, ethernet, and similar communication connections. Host system monitoring includes connecting to and capturing the temperature sensing, fan speeds, voltage sensors, serial port I/O for low-level text and IP access to the BIOS, operating system and boot logs, keyboard/video capture and control, LAN access for testing local connectivity, secondary "back door" IP access, and other peripherals. This device is totally unaffected by failure of the CPU, motherboard, power supply, physical room power, UPS power availability, and the network. In addition, the maintenance device interfaces with, but is not affected by, I/O cards, external network switches and hubs, and local physical Internet or telephony lines, and various adapter cards. Separate operating software is used to operate the independent maintenance device which separates it from software corruption on the host computer. |

DETAILED DESCRIPTION It is an object of the present invention to provide an independent computing device for diagnosing and repairing a host computer.
It is another object of the present invention to provide an independent computing device for diagnosing a host microcomputer when no power is supplied to the host computer.
It is another object of the present invention to provide an independent computing device for independent diagnosis and recovery when the software or hardware of the host computer is not operating properly.
It is yet another object of the present invention to provide an independent computing device for independent diagnosis and recovery when a land based telecommunications line or local area network connection is not operating properly.
This invention is a remote maintenance device for monitoring and controlling a host computer and its operating system.
The device allows a remote administrator the same functionality as if they were sitting at the host's console.
The device is fully independent of the host computer's hardware and peripherals (including local power, network, and telephony) and fully independent of the host operating system and BIOS.
The remote maintenance device uses a wireless modem (GSM) or wireless IP (packet) interface to provide commands from a remote technician to the host computer.
The wireless communication link also transfers output or display data to the remote technician who can then diagnose and repair problems.
Because of an onboard battery, the host computer may be reset and the power toggled on and off without affecting the maintenance device's operation.
The maintenance device accesses the host's operating system and BIOS via serial ports and similar communication connections.
Host system monitoring includes connecting to and capturing: temperature sensors, fan speed sensors, voltage sensors, serial port I/O for low-level text and IP access to the BIOS, the operating system, keyboard/video capture and control, LAN access for testing local connectivity, secondary "back door" IP access, and other peripherals
