Troubleshooting/Repairs
I also troubleshoot and repair all types of assistive technology, including:

special pointing devices and keyboards,
such as this very small Tash keyboard
laptop computers, including cases, buttons,
screens, batteries, and keyboards
Windows computers, usually on-site,
including hardware problems of all types
software problems, such as a "missing" USB.INF file, which disabled all USB ports on this computer
(Vista suddenly couldn't find the file until I copied it to the right place - two folders over.)
devices for people who are blind or low-
vision, including Braille 'n Speaks, braille
printers, speech synthesizers, and even
Perkins braillers
Macintosh computers, including hardware
and software problems
electronic equipment of all kinds
(a Comfort Keyboard control box)
electric door openers, in or out of warranty
porch lifts (miswired at the factory)
and other mobility devices
eMotion power-assist wheelchair wheels
(a $4700 electromechanical wheel, made in
Germany, no US repair centers)
unusual items, like this new $700 bidet seat
(broken mounting plate and bolts - a new
one would have broken in the same places)
Replacing a failing hard drive includes moving as many files as possible to a new drive. In this case, I got all of them before the old drive permanently quit.
