How do you explain what magnetic fields do to monitors to people wearing bowling shoes?

(2025/04/04)


On Call The working week sometimes speeds by, sometimes crawls, and often ends with a crash. Each Friday, we try to avert the latter by delivering a new edition of On Call, The Register 's reader-contributed tales of handling ridiculous, ribald, and remarkable tech support requests.

This week, meet a reader we'll Regomize as "Simon" who shared three tales of extremely rapid tech support satisfaction that challenge our arrival-to-fix world record of [1]8.5 seconds .

We'll open with his story of a remote support job that came his way during COVID-19 lockdowns.

[2]

"A user told me the Lenovo laptop they'd taken home was broken because nobody could see or hear them during Teams meetings," Simon told On Call.

How do you explain magnetic fields to people who dispense bowling shoes for a living?

Simon knew his colleagues had not been equipped with external cameras, as the Lenovo machines' internal webcams and microphones were sufficient.

He therefore asked if the laptop's webcam shutter was closed.

[3]

[4]

"I just need to move my books off the laptop," came the reply, for this user was operating with her computer closed and the webcam pointed down at the keyboard.

On another occasion, Simon was summoned to a bowling alley to fix what he'd been told was a "wobbling monitor."

[5]

On arrival he found a large cathode ray tube monitor whose output was indeed wobbling around the screen.

Simon noticed the monitor was illuminated by a large Anglepoise lamp. You know the sort – they have a big metal shade at one end and a flexible arm held in place by large springs.

He swung the lamp away, so it was a little further from the monitor. Doing so had the effect of moving the magnetic field the coiled filament of the lamp produced far enough away that it stopped affecting the electrons streaming out from cathode ray tube.

[6]

"How do you explain magnetic fields around a helical filament to people who dispense bowling shoes for a living? " Simon asked On-Call.

He rated the time spend working on that fix as "less than Usain Bolt hitting the bar at last orders."

[7]Tech support session saved files, but probably ended a marriage

[8]Weeks with a BBC Micro? Good enough to fix a mainframe, apparently

[9]User complained his mouse wasn't working. But he wasn't using a mouse

[10]Glitchy taxi tech blew cover on steamy dispatch dalliance

Simon's other super speedy support success came in the 1980s, when he was asked to visit a user who couldn't reset their computer.

This was a time when some machines – especially from IBM – came with an actual lock that had to be opened before the keyboard would work.

Simon drove for an hour to reach the user's office, noticed the lock was closed, inserted and turned the key, and left.

"Total hands-on time approximately two seconds," he boasted to On Call.

Have you fixed things faster than Simon? And do you have any tech support stories from the COVID years? Hurry up and [11]click here to send On Call your story so we can rush it into production on a future Friday. ®

Not really a fix, but magnetic fields were involved

Michael H.F. Wilkinson

Donkey's years back as a student, I was visiting a friend who complained that her cassette tapes seemed to degrade. One glance at her stereo set-up showed she was storing her collection on top of one of the speakers. Not the best place. When I suggested that the proximity to the speaker could be the cause of the trouble, she moved the tapes, and put them on top of her (classic, CRT-based) TV, which I suggested was also sub-optimal. She was certainly smart enough to understand my explanation involving magnetic fields, and found a safe spot for her cassette tape collection on a bookshelf.

Anglepoise Lamp

William Towle

I ended up with an anglepoise type lamp for the computer desk I had when I was growing up - if I closed the curtains when it was sunny an additional light source was useful.

I don't recall it causing a problem with TVs or monitors, but I didn't use the lamp all that much either - even with a single coil 40W bulb in it the metal shade got very hot. I expect a modern bulb would be better suited.

It still exists. As does its bulb ... which I did just go look at to check its rating.

Re: Anglepoise Lamp

I still have the Anglepoise lamp I bought when a student back around 1972. It's now fitted with a 7W LED and used if I'm at my desk at night (when there's no natural light coming in the skylight right above the desk). The LED is noticeably lighter (weight-wise - luminary-wise, it's about the same) than the tungsten filament version the lamp had been designed for, so I've had to add a small mass* behind the shade to maintain the counterbalance for the springs.

*One of those reflective bands that snap around the wrist - it was to hand, not needed elsewhere, and does the job without fuss.

I've had to add rubber bands to augment the springs for the heavier LED lamp.

I'll never forget this one

I had a call once which , had the servicedesk relayed the problem in any sort of useful way could have been solved in record time with a phone call simply saying "remove the floppy disk from the machine" . As it was it it took a 15 minute walk to another site to get to the machine and appraise the situation.

They managed did a masterful job of interpreting the users dilemma and gathering the symptoms to aid support guys diagnosis and logged what should have been "machine wont boot , screen says no command.com on A"

Not magnetic field, more star field?

Anonymous Coward

I was once woken at an ungodly hour because there was hardly any data coming in from the motorway ANPR cameras.

I spent an hour or so checking all the IT systems, rebooting things and couldn't find the cause of the issue.

Futher conversations after that, I found out there was heavy snow across the region.

The cameras couldn't see any cars because they were covered in snow.

Back to bed I go.

(I think these days they have little wipers and/or better covers!)

Re: Not magnetic field, more star field?

Anonymous Coward

Many years ago, people were called out of bed in the middle of the night as no stats were being received from Europe's biggest on-shore windfarm. After lengthy diagnosis from various parties, the root cause was determined:

There are no readings as there is no wind to generate electricity.

The best are when you arrived at said persons desk, they went to demonstrate the issue and it just worked.

That said, you then got the late Friday afternoon call that on paper and in your head say 5 mins tops. late Friday night and you are still battling away, cursing and thinking "When will I ever learn, the quick 5 mins jobbies at the end of the day are anything but..."

Re: Ones Aurora

I've seen those described as Crackerjack issues: "It's Friday, it's 5 to to 5...". Part of the reason we don't do deployments on a Friday.

There was a TV program about the Forestry Commission in Scotland, one of the guys said you can guarantee you'll get the quad (bike) stuck on a Friday afternoon when there's no one else around to help.

Simple jobs on paper are sometimes the most challenging in reality.

Contrex

I don't believe that the coiled filament of an incandescent bulb would produce enough magnetic field to affect a CRT monitor that way. Look at the wire gauge and number of turns a degaussing coil needed. If the story is not BS, as are a lot of 'tech anecdotes' I suggest perhaps the lamp arms and base were made of steel that had somehow become magnetised, or as with one such lamp I had, the base was weighty because it had a 240 volt to 12 volt transformer, and the lamp head had 12 volt bulbs, with a base the same as older car side light bulbs. But I'm still doubtful. PS - I just took a magnetic compass to a lit filament desk lamp. No deflection.
