    Power Cables...

    I've had a few power cables not properly plugged in over the years. I always used to ask them to unplug them and plug them back in, try a different cable, etc. warning them that an engineer call would be chargeable if it was just that. They still wouldn't listen!

    Years ago when working for a small software house selling Apricots we always knew from the symptoms when a computer had been switched off or unplugged without being shut down. I had one user who insisted that this couldn't possibly have been the case, she'd left her desk for a few minutes and the data had spontaneously become corrupted. A couple of hours later she phoned back, very apologetic, her boss had managed to dislodge the power cable and plugged it back in hoping she wouldn't notice.

      Yup, had one when I was at uni. One of the students reported a PC wasn't working, so I followed her to the room. Sure enough, it wouldn't turn on. Went to check power socket, the plug was slightly out. Pushed it in, powered on the machine gave her a bit of a look as she was looking sheepish and wandered out without saying another word.

          "Use latching IEC power cables!"

          It is surprising to me how iffy the standard ones are . Many times I've arrived at someones desk ( who's brilliant diagnosis of "I cant do my timesheet" turns out to be lack of 240v to base or screen ) and started swapping the leads around from screen to base to pc at next desk in order to establish if it the lead , the fuse or an actual fault with the Equipment. 9 times out of 10 , after a bit of swapping around the fault disappears and everythings working! Its kinda frustrating and a relief at the same time.

          (latching IEC cables)

          Unfortunately these don't hold the plug in, but they do stop stuff coming out of the back of the computer.

          You can get PDUs with latching IEC sockets too:

          http://integra-pdu.co.uk/click-lock-pdu/

          There are also friction sleeves for PDU C13 sockets to stop them popping out (APC ones are terrible for this) - https://www.tripplite.com/c14-plug-lock-insert-for-c13-outlets-blue~PLC13BL/ - they're a bitch to use but they do stop accidental unplugging and they're cheap.

          Click-locks grab onto the earth pin and don't require a special plug or other malarky like virtually every other kind of locking connector does. They can be pulled out without releasing the grip, but it takes a hell of a pull. http://www.ieclock.com/videos/?slug=how-it-works--iec-lock-outlets

          These really are bloody useful when fitted to a PDU in the back of a rack or other cramped enclosure. It's just a pity you can't get locking 13A UK sockets.

      A classic is with the last couple of generations of Dell laptops. If the power cable is about 1-2mm from being fully plugged into the machine or dock, the machine will operate on AC power, but no battery charging will occur. Drove us crazy until we realized what the cause was. Apparently the pin that provides telemetry doesn't quite make contact.

        Yep, had the same thing a couple of times at my site. Also had to deal with a couple of cases where other techs had replaced the docking station (with the not-quite-plugged-in power cable), then declared the dock as dead when the replacement one worked with charging.

    Second question:

    Is the On/Off switch in the proper position.

    My keyboard stupidity.

    Friend reported that her Sony laptop's keyboard was playing up. I too couldn't access certain letters on the keyboard and feared the worst because it persisted even after rebooting the machine. After some head scratching, turned out that this Sony's Num Lock remained on despite restarting the computer.

    Lesson learned -- though I never got round to testing whether this was normal for all brands as I avoid using laptops because the keyboards are, generally, so awful.

    In my defence, I should add that the Sony's Num Lock LED was particularly small.

When I comment, the answer is always "x system requires everything to be in capitals". My answer is always "there is not a single system in our company that requires all capitals". Doesn't change anything.

            I swear, one evening I'm going to take a screwdriver and break all of the Caps-Lock keys off of every keyboard in the company. I wonder if anyone makes a keyboard without Caps-Lock? I could be a product idea?

            A tie, I fear, between Capslock and Numlock on laptops where it used to take over the right hand side of the keyboard.

            Although back when I got paid a bonus per fix, I used to love getting the jobs of "letter keys keep typing numbers". A five quid keypress, and try not to make the job card back to the customer too sarcastic.

          If only caps lock on a PC worked the way it did on (many? most?) manual typewriters and pressing shift would release caps lock. In a lot of cases that would self-correct the error reasonably quickly.

            Re: My keyboard stupidity.

            The one I always fall over when using French colleagues machines (with their keyboards) as the numbers are on the shifted keys there, with the punctuation etc being the "normal" keypress.

            Apparently it's designed that the users use the number pad for the numbers and so having them directly on the row above the letters on the keyboard is redundant. But of course this does not consider that a) they're the only ones that do this, so everyone else just gets confused and b) the laptops we have don't have number pads, although the external keyboards do.

            Hence when they're doing a lot of number work they use caps-lock (which puts the number row into number mode) and then tend to leave it that way.

            These days I just switch the thing over to UK language/keyboard mode, touch-type and be done with it. And of course get moaned at if I forget to switch it back when I finish.

        But not the worst one I've encountered, on a laptop from a couple of years ago.

        It's common on laptops for the F1-F12 keys double up as system functions; press 'fn' and one of them to turn up/down the volume, brightness, whatever. But on this laptop, they defaulted to those system functions, and 'fn' had to be pressed to use them as F1-F12.

        I use a piece of software A LOT that uses certain of those keys, so it was bloody annoying until I found the relevant BIOS setting.

          But I hate that trend, and wherever possible switch it back.

    Monitor weirdness

    I have three monitors on my Office PC. Shortly after I moved to my present location I found that one of them randomly goes black and mostly comes straight back on. Occasionally though it stays black and it is necessary to switch it off and leave it perhaps 10 minutes before I can get it back to life.

    Eventually I realised that this flicker only occurs when someone uses the shredder. It doesn't happen every time the shredder is used and it's better than it was now I have a surge protector extension lead on it, but it is still an annoyance.

    Electrical noise spikes were always a good reason for being on site and chatting to people who are not responsible for sorting the problem. Several times someone apparently unconnected with the problem would say something like "It always goes down when I'm on my coffee break" (kettle); "It always goes down when I go to the toilet" (macerator).

    One memorable problem wasn't electrical. The software development mainframe crashed. Every time it was brought up it would last a few minutes before crashing again. That was not long enough to print the diagnostic whole memory dump that had been written to tape. Eventually we resorted to printing directly from the crash state - which kept the service off for quite a long time.

    With the diagnostic dump secured the operators tried to bring the mainframe back into service - with another crash after a longer period. Meanwhile I looked at the dump and diagnosed a software bug caused by a terminal's input. There were terminal rooms all over the tall building but fortunately the dump identified the device's position.

    Trotted off to find a woman sitting at that terminal. She immediately complained that the service breaks were interfering with her work - writing a BASIC program. "Every time I enter this line the service goes down".

    She had decided to number the lines in a new subroutine starting at 1000000. The BASIC interpreter had never been validated against such high line numbers.

Eventually we put someone in to watch what was happening, and, at the time we should have been polling, the cleaner was in, and unplugged the modem to plug the vacuum cleaner in.

      Re: EMP crashes

      I get a call from one of our satelite offices complaining that "everything's gone black & won't turn on". I do the standard troubleshooting steps but nothing fixes the issue. Then there's a noise in the background that I can hear through the phone & ask "Was that thunder?"

      The caller says "Yeah. There's a massive storm going on. We even had a lightning strike a car in the carpark".

      O.O? O.O! Stop trying to turn electronics on in a T&L storm you twit! Unplug everything from the mains so it doesn't die when the power comes back on!

      "Is that what those ghastly yellowish light panels glowing in the ceiling mean, that we've lost power?"

      ARGH! You fekkin muppet. Please step outside & hold up a cast iron rod, hug a flag pole, or climb a power tower...

      *HeadDeskHeadDeskHeadDesk*

      On the plus side I wasn't required to go out to the site to further troubleshoot the issue. Unfortunately I had to go out once the storm was over & fix all the stuff that had fried. UPS? What's one of those Guvna?

        Nah, eroding workers rights should be easier, so they're going to do that first. Then they can loosen up rules on electrical stuff, because as well as stopping it interfering with other things, they can also take away any safety regulations at the same time.

    Laptop function keys are fun...

    Pretty much all models have special actions assigned to the function keys - volume controls, external screen controls, etc. Usually you have to press a key (e.g. "Fn") to activate these special actions.

    However, on one particular model, these "alterative" actions were enabled by default *and* one function key controlled the wireless functionality.

    I'm sure you can guess the rest. "My laptop isn't working - it's the end of the world!". And then I reached over and tapped the function key...

    a bit off topic , not electrical fault based , but while we're having a go at users ....

    I find that if a user requests something , hardware , software , or merely how to do something , you will usually find that they are trying to do something idiotic and pointless that could be far more easily achieved using resources and techniques they already have such as email . or renaming a file.

    For example if a user requests a printer , make sure its not purely to feed the scanner they ordered last week.

    I once met a "technology" (oh the irony) lecturer who thought printing 100 pages of A4 text (with drawings) was a good document storage technique and if it needed altering in the future it could be scanned in again.

    Right now im listening to a colleague explaining why a pdf cant easily be converted to a word document - you gotta wonder whats wrong with the work flow there.

    Surely theres a career to be made explaining to users what can and cant be done and the easiest way of getting from a to b ? or would that be "serial meddler" , or "Business analyst" or architect?

    one more from the old days: "I want to purchase 15 modems so my team can all get on the internet"

    The trick is to recognise these whacko plans early on before you've wasted a lot of time and money setting something up and assuming they had a legitimate use for it.

      I've noticed recently that Google are doing OCR on the content of PDF files - not just the ones which contain proper text, but the content which started out in picture form.

      It was quite disconcerting when I first encountered a file where Find didn't locate the text that Google had indexed.

    I used to be called anal at my last place because I was forever attempting to clean up the cables from just lying on the floor under my colleagues desks - yes we did have the occasional issue with monitors or iMacs just 'not working' for no reason - until you pushed the cord back in properly.

    Saved the best for myself though: located onto a new set of desks, my feet were exactly inline with the double socket powering my own PC/monitor combo.... yes I did manage to tap the switches with my toe.

    Many moons ago we had a customer, a wine dealer by trade, with a leased-line modem link to his head office.Periodically he would report an intermittent fault that had cleared by the time one of our guys turned up. Just about everything got changed out, but the intermittent problem kept occurring. Then one day he phoned up and said he thought he had the answer. He was next to a coffee shop and the problem seemed to occur just when they were opening. We turn up at the crack of dawn with a test set and some very expensive main monitoring kit from our research people, set the kit up to run round a loopback on the remote modem and sat back sipping a very agreeable sherry at 8:30am. Nothing!! The odd error and minor flicker on the mains, but nothing worthy of crashing the modem link... that was until he got out of his chair and walked around the desk... the error counter went haywire!! Yes folks, the cable between the modem and his terminal ran under the carpet and as he walked over to get the same ledger at the same time every day he was treading on the cable. (pint'o'beer icon 'cos yer out of sherry... the vicar must have been round again!)

    Clean keyboards

    Worked in a place the early 90s where the managing director's PA got a bee in her bonnet about 'unhygenic keyboards spreading disease'. This resulted in a cleaning company coming in every few months to clean the keyboards and mice. Only problem was the cleaners were more used to mopping floors. Their usual method was to dunk said mouse and keyboard into a bucket of warm, soapy water and scrub vigorously! Needless to say, we had a few problems after every visit (but sparkling clean hardware).

    You want fun try having a batch of bad power cables. Oh those are so fun. Asking the end user is it plugged in. I'm not a fucking idiot. The question was why couldn't we use the cables that cable with the computers. Answer because they have not been certified. I think this changed when a high end server blew up because the hot and neutral were swapped.

    Call came in from remote site. Server dieded. Walked the tech through all tribbleshooting steps with no success.

    Server was shippes to us for testing and repair. With it came a new motherboard and new hotswap PSU's.

    Motherboard was the wrong model. Hotswap PSU's ditto.

    Oh, and it was mentioned they have zippo on backups, and I should be verra, verra careful with the RAID....

    Then I noticed my appy had the same model of the server we're trying to troubleshoot. Whipped out his working PSU, plonked it into the dead server.... nothing. Then it was eaay to deduct the cause of the dead server - PSU redundancy board failed.

    Transferred all the hardware (RAID cage, mobo etc over to the appy's server chassis, fired it up and up she came. Lovely.

    Did a few initial tests and all was OK, no database corruption or nasty RAID borkage. Just for kicks we queried the date of the last transaction, and found the server dieded two days before it was reported.

    Appy was not happy with a stripped server, but he took it well. Bless him.

    Client was super chuffed that we could resolve this issue on short notice.

    In the meantime I have ordered a replacement redundancy board, still waiting. Meh.

    Server (Not) Hacked!

    I once had a client whose machine was typing stuff and moving the mouse about. He immediately jumped to the conclusion that the (external) web/mail server had been hacked. No I don’t know either.

    After failing to make sense of “it’s just doing things on its own” and asking him to unplug the network cable to rule out a remote access attempt, I asked him if he was using a wireless keyboard.

    Turns out someone on the floor below was using the same make/model/frequency and operating both machines. At least it didn’t need a trip out.

    Bah!

    Me and Rudy were a superteam. I did the server config and ticket resolution, he did the site survey and equipment installation. His job involved heavy lifting and swearing at people. Mine involved looking at screens and using my scary spidey senses to figure out WTF was going on.

    ------------------------------------------------------------------------------------------------------------------------------

    Ticket: "Server unresponsive between 8pm and 9:30pm"

    Me: "Rudy, nip over to 10 Drowning St and fit a screw-secured power outlet/cord so the office cleaners quit unplugging the server to run their vacuum".

    Ticket: "Server unresponsive between 11 am and 11:15 am."

    Me: "Rudy, nip over to 666 Lucifer Avenue and fit a screw-secured power-outlet/cord so the office workers quit unplugging the server so they can plug-in their coffee maker."

    Ticket: "Server unresponsive between 8:30 pm and 7:30 am"

    Me: "Rudy, nip over to 69 Rue de Remarques and move the server power cord to a power outlet on a different circuit to the office lights."

    Ticket: "All servers at 99 Wall St unresponsive"

    Me: "WTF?"

    Rudy: "The building manager had some work done. They took a sawzall to a non-supporting wall. The wall had the main optic fiber trunks running up and across it. You're gonna need a bigger engineering team."

    Ticket: "All servers at 404 Nosuch St offline."

    Me: "Can't be a sawzall. They have concrete walls ferfuggsake."

    Rudy:" Electrician needed to drill hole in main power distribution box to add a circuit and saved some time by not throwing off the main breakers. His burning corpse set the building on fire. F*** this for a game of soldiers, I'm going to the Brewer's Elbow for lunch."

    .....call from the production line came in - one of the Sparc's had gone up in smoke.

    Attending the location I was informed there had been a nasty puff of smoke just as it stopped.

    Opening it up - yup - there was a deep-friend motherboard with a strange brown/burnt stain in the centre of the motherboard. Now on these babies the power supply was actually locked into the top-half of the case and came off with the case when you opened them up - so the initial thoughts were that something nasty had leaked out of the power supply.....

    Anyway, replaced the whole machine and took the dead one back for diagnostics. Curiosity caused us to plug it in - and the power supply came online... no issues..... thats strange. Motherboard was dead. Buts what caused that stain/burn mark?

    Later that day walking through the production line I see the same guy drinking a can of coke. Seeing me, he puts it down on a nice flat surface... yup... the lid of the Sparc (which has vents in the top).... uhmm.... a bit of questioning and he admitted that he had spilt a can earlier - but he mopped up the top of the computer so was sure it wasnt that that caused the problem.......

    coils and spiking

    "It turned out that this forklift had some sort of fault that caused its ignition coil to radiate excessive RF noise. The problem was corrected on the forklift and the crashes stopped."

    My old Mini had a slight short or something in it's distributor cap (can't remember the exact fault, over 20 years ago). And my girlfriend's family would know exactly when I was coming to visit as it would cause some static on their TV from about half a km out.

    I remember once when I was working for a local council I had a similar issue, customers computer, their screen etc was off, came up with a few new power cables and that didn't fix the issue. Spoke with the user at their desk and asked if they had something I could plug in to see if the power bank sockets had failed, there was this heater she had under the desk and she switched it on and everything else came back to life.

    That one made me laugh
