 urges,
sags, and blackout……..what really happen to your computer when it
experiences an "out of bounds" power anomaly.
We'll use SURGE as an example, although it is just one of countless
problems that can strike your system. If the surge is powerful enough,
it travels instantaneously though wiring, network, serial and phone
lines more, with the electrical equivalent force of a tidal wave.
The surge travels into your computer via the outlet or phone lines.
The first casualty is usually a modem or motherboard. Chips go next,
and data is lost.
The utility responds to over voltages by disconnecting the grid.
This creates SAGS and BLACKOUTS. If the voltage drops low enough,
or blackout, the hard disk may crash, destroying the data stored
on the disk. In all cases, work-in-process stored in cache is instantly
lost. In the worst case, password protection on the hard drive can
be jumbled, or the file allocation table may be upset, rendering
the hard disk useless.
Even the smallest disruption in electrical power can cause damage
to a computer, a network or other sensitive electronic such as cash
registers and process control equipment. At the very least, power
problems cause data loss and unexpected shutdowns. At the worst,
"BAD POWER" can damage or equipment.
Commonly, bad power causes a computer's monitor and indicator lights
to waver or flicker, unexplained errors in data transmission, sudden
loss of Internet access, a system lockup, aborted modem transfers,
and hard drive crashes.
Even minor power problems can cost your money. Anytime a power interruption
delays your work in progress, that's your valuable time you've lost,
and lost time means lost money. More serious and expensive is the
fact that power problems can not only corrupt expensive data files,
but also can permanently damage computers, networks, and precision
electronics. |
