603 or 604 is the certification in help desk support which this is. You can't just switch off a computer then turn it back on again for two reasons.
1) Viruses can remain in the memory even when the power is switched off, to turn off then on again give the capacitors no time to drain fully and the virus would still be there
2) Powering down a computer in use can cause damage through the heads on the hard drive therefore wiping or corrupting the data at that segment.
The correct method would be to press reset.. If that fails, then you can power off, unplug (as ATX systems have constant feed through the PSU) and wait around 10-30 seconds before plugin it in again. Always works for me
When I say 603,604. I mean 220-603, 220-604. It's part of the new 2007 CompTIA certification for A+
Well, turning a computer off, and waiting a seccond or two will often trigger a reset cycle, and that will AT LEAST reset the pointers so an IN MEMORY virus WILL be wiped out. Of course, it likely is on the disk, so the reboot might reload it.
Any decent drive will park the heads first! Of course, you DO want to wait a second or two before turning the power back on. And any DECENT O/S writes to the disk ONLY when it writes! In fact, UNIX will often CACHE and do a write behind. That means that such a power down WILL cause lost data on UNIX, but it WILL trigger a chkdsk, which will validate and fix allocation errors. Of course, M/S Windows is a PIECE OF GARBAGE, so IT writes ALL THE TIME and a reboot can destroy data and programs and other things, and they NEVER had a faciility to check/repair the disk until WINNT format! And THAT is "quiet", so you are left wondering if the system will ever come back.
They REMOVED the reset button over a decade ago, because many would use it and likely wipe out data. Oh SURE, they removed most of the power switches ALSO, and have them HOPEFULLY access a routine in the BIOS. So trying to turn it off triggers the shutdown sequence(NOT the same as a reboot), and HOLDING it will HOPEFULLY turn the system off. so they design the computer so the people that DON'T CARE are all but forced to comply, and the people that know better suffer!
As for the show and characters, I know about neither BUT..... I was struck by how AS criteria so closely match the TRUE computer geek stereotype.
