Heh. I've surprised a lot of laymen, after telling them I'm a

I share your opinion that most software and consumer electronics is
terrible. Of course, I've produced my share of terrible software, but
I won't make any excuses for doing so.
For example, my TV set crashes every once in a while, and must be
power cycled :-(
The old analog sets never did that!
That's nothing. My laptop power supply crashes every so often and starts
failing to report itself to my laptop. It then has to be power cycled. I
am not making this up!
Well actually that's a different matter altogether. Power supplies are
switching devices that, when old, fail to maintain oscillation. When you
power cycle them they usually re-prime themselves because there's some
simple electronics that does it. If you listen carefully to the source,
you may hear a high-pitch sound when it's working. The louder the noise,
the older the source.
Failure to report comes from the third wire that connects the source to
the laptop. That wire is quite thin and is the first to break on an
older source. The manifestation is that the laptop intermittently fails
to figure that it is connected to a correct power source.
Time to change the power brick. Many go for under $10 on ebay, free
shipping. (How the heck do they make money off them?)
