Firstly, effective computer
and/or laptop troubleshooting requires a tidy, well-lit,
spacious, dust-free and organised workbench, plus a tidy,
patient, organised, and logical mind. A 'feel' for
electronic components, and appropriate tool use, are also
necessary, some parts are very fragile, some are easily
damaged by EMF, all require optimum conditions for storage,
assembly, and continued use. A good basic supply of
'known-goods' is important for component testing, plus
appropriate tools, including voltmeter, USB socket tester
and/or light, laser heat-sensor, propyl alcohol, PSU tester,
'magic' contact spray, mains test lights, mice, keyboard,
monitor(s), converters, soft natural fibre brushes,
air-blowing/compressing source, magnet rod, magnets from
HDDs for tool attachment, etc. Most importantly, be
well-rested and relaxed, with a clear mind, before tackling
computer troubleshooting.
Note-taking,
photos,
online or other info sources, plus proper record-keeping,
are also necessary. For the beginner, checklists and reminders will be
especially useful, a felt pen will always be useful. Marking
components or systems will avoid double handling, and, help
with part storage and search, etc. Shelves with marked
storage containers are a must. One good desk system, always
online, will be useful for checking facts, specs, etc, via
Google. An extra test system or 2 can be useful for parts
and/or software testing. Note also that proficiency
with computer assembly, disassembly, and troubleshooting,
should precede such involvement with laptops, notebooks,
etc.
Test
all
variables sequentially, to be more precise, and, be ruthless with separating good parts from
bad, tho proper recycle is recommended for faulty and
unwanted parts. Without observing all of these listed basic
requirements, troubleshooting efforts may well fail. A professional will need
to deal with less-than-adequate conditions if out on call, but, ability to deal well with lesser conditions is
made easier with properly learned work-habits, and an
orderly mental approach. Encourage all computer
work to come to your own workshop, if possible, where familiar tools and surroundings
make all such work much easier.
