If a person says it's difficult, then it's difficult for that person. To belabor the
point might come across as a put down. Think of it this way: Tom, you use appositives on
a regular basis; you are surrounded by them. The day may come when you need to know how
to work with one. I could explain it this way:
An appositive is the result of eliminating a be-copula with its preceding relative adverb
and placing commas before and after the thus-created reduced relative phrase.
Is that so difficult?

Perfect! I've got a grasp on the concept now. Here's my next question: When the circuit
breaker trips, I reset it, then find out what caused it to trip and fix it. In my
computer, is the "crowbar" a multi-use mechanism? Or did this one event use it up, so
that I no longer have crowbar-protection on my computer?
BTW, this machine was built in 2001. I've replaced one of the hard drives and added a DVD
burner. It's still serving me well. I'll try to find the tech that built it for me and
thank him for using a good power supply with a crowbar.

No a good power supply should be able to use the crowbar
circuit multiple times.
The real question is your surge protector any good after
"winter weather jiggled the electrical lines. ". Most surge
protectors lose their ability to stop surges over a period
on time. If it was a major surge because the electrical
line that jiggled where next to your house or just down
the street then there is a good chance that your surge
protector died in the process of trying to protect your
PC, but after it died some of the electrical surge got
through to your PCs power supply causing the
crowbar circuit to kick in.
So it may be time to replace the surge protector,
especially if your PC is working fine and the power
supply has not tripped crowbar circuit since the bad
weather incident.

It's still serving me well. I'll try to find the tech that built it for me and
thank him for using a good power supply with a crowbar.
The tech was required to use a power supply with a crowbar; as was
standard in the very first IBM PC and in computer power supplies long
before that.
If power cycling an AC switch solved that problem, a crowbar was
probably unrelated to and did nothing during the event.
Your symptoms are consistent with another completely different
function that should be in every power supply 'system'. Power supply
controller contains a safety lockout function. Depending on how power
is restored, that lockout function may be triggered. Lockout is reset
by disconnecting AC power either by unplugging or by cycling that AC
power switch.
Meanwhile, a surge would not get through a power supply and trigger
the crowbar. If a surge got through a power supply, then the power
supply was damaged AND the house is full of other damaged appliances.
Based upon your symptoms and how it was corrected, a safety lockout
circuit was triggered probably due to AC power that went off and on
repeatedly before finally staying on. Crowbar and surge protector
would both remain inert - do nothing - in that kind of event.

You guys have been so sweet! I'll get a new surge protector. I feel really lucky that my
desktop computer revived. In the meantime, however, my old laptop died. The hard drive
started clunking, and now it won't boot up; I get a message that there's no operating
system. It, too, was about 7 years old, and served me well.

If you still have the Windows CD that came with
the laptop you could replace the drive. But with the cost
of the hard drive and the repair shop labor charges it may
be more advantageous to buy a new laptop.
Dell and HP have been selling some laptops for under $500.00
but stay away from the laptops that have VISTA "64 Bit"

Changes are the disk drive has simply died with no relationship to
AC power.
Meanwhile, just because it is called a surge protector does not mean
it also provides surge protection. Protection is earth ground.
Protector is simply a device to connect surges to earth. But plug-in
protectors don't have that necessary earthing connection; may even
earth surges destructively through the computer.
If concerned with such AC electric anomalies (that typically occur
once every seven years), then you need one protector for everything in
the house that actually has that earthing connection. 'Whole house'
protectors are sold only by more responsible companies, are located
where your utilities enter the building, and have that short (ie 'less
than 10 foot') connection to earth.
You phone line and cable already have those protectors installed for
free. But AC electric does not until you have it installed.
Responsible names include GE, Siemens, Cutler-Hammer, Intermatic,
Leviton, Keison, Square D, and others. Not on that list are less
responsible companies such as APC, Tripplite, Belkin, and Monster
Cable. Products from the latter have no dedicated earthing wire AND
do not even claim to provide surge protection in their numeric
specifications.
Appreciate the difference between a protector and protection.
Effective protection ends up costing about $1 per protected appliance
AND actually does earth a type of surge that is destructive.
