Technical Support
I am able to provide technical support in terms of hardware and software upgrading, installation, configuration, troubleshooting, etc.
My experience with the operating systems / software aspect of computing is covered in more detail in a number of other pages in this site.
In terms of hardware most of my experience has come via practical sessions through Scheidegger Training, and also adding new components to my own pc. I have also had some training in and experience of networks, although my stongest area is with standalone personal computers. For my qualifications please refer to my page on this subject.
The following is a list of the main topic areas covered in the Scheiddegger course, and the Networking Course I undertook at Lewisham College:
- Hardware
- Mother/system Board, PSU, power connectors, bus architectures, expansion cards, IDE/EIDE and SCSI devices, disk drives, CPU and sockets, chipsets, RAM, ROM, CMOS settings, system clock, IO devices, cables, connectors, ports (PS2, Serial, Parallel, USB, Firewire, etc), signals, voltages, jumpers, dip switches, system optimisation, etc.
- Test Equipment
- Multimeters, digital and analogue, measuring supply voltages at PSU and disk drive, resistance checks: continuity of external cables and connectors.
- Visual Display Units
- TTL and linear/analogue technology, RGB +/- separate and composite synchronisation, connectors, display adapters, CGA, EGA, VGA, SVGA, installation, adjustment, troubleshooting, etc.
- Printers
- Principles of operation: dot matrix, daisy wheel, ink-jet, laser. Feed mechanisms - single/continuous, friction/tractor feed, Connections: RS232/Serial, Centronics/Parallel, USB. Driver installation, configuration etc.
- Operating System Configuration and File Systems
- DOS/Windows installation and configuration procedures, system boot sequences, device drivers and their configuration, DOS and Windows system files, file management, disk management.
- Networking
- Network types and topologies (LAN, WAN, peer, server, bus, star, ring, etc.), cabling and connections (co-axial, twisted pair, fibre-optics, etc.), wireless systems, network adpater card configuration, protocols, network operating system installation and configuration (esp. Win 2000 Professional and Server), the OSI Model, etc., etc.
- Portable Computer Systems
- The major differences between desktop and portable systems and problems specific to the latter.
- Troubleshooting, Repair and Diagnostics, Preventative Maintenance
- Error codes, viruses and their management, diagnostic utilities, use of test equipment, etc.
- Safety and Precautions
- Awareness of Health and Safety issues and precautions to be taken to protect equipment when working on it.
