  • the keyboard gave up the ghost on it a couple of weeks ago; and the DC cable from the power supply had an intermittent break in it.

    All happened just as I had to deal with filling out an Ofcom license form amd multiple telecoms routing faults at remote sites; then I had to keep out hackers from a VOIP circuit.

    These are not the most fun tasks anyway and hard on the back/eyes/knees as well as brain when you have to use two netbooks of varying stability/reliabilty and the newer Raspberry PI hooked up to a cheap ASDA LED telly (as it has HDMI input). There is some stuff I can do easily on Windows such as ssh tunnels at a remote linux box that I still struggle with on Linux desktop [which probably doesn’t seem logical to anyone here who does know computer science better than myself] but I was too busy partying when I was supposed to be learning that stuff.

    At least I remembered to put the chopstick back in the drawer it came from (the ribbon cable from the keyboard to the rest of the laptop is held by a particularly fiddly and fragile connector; and there are some hidden plastic latches that hold the keyboard in. You are supposed to use a “flat plastic screwdriver” but I’ve never seen one of sufficiently strong plastic sold in any British electronics supplier (metal tools can scratch up the PCB tracks and knacker the motherboard).Nor did I absent mindedly add a few shots of isopropyl alcohol to some fruit juice I was drinking (that can make you quite ill).

    Ok there is a sketchy splice in the DC power cable and the whole thing probably puts out even more radio interference but it works and I wasn’t immediately wanting to buy another PSU for about €50

    I think I read this wrong. Something like “I’ve buggered my fixing laptop”.

    I still can’t make my mind up what you were trying to say but no doubt you’ll remember it if it’s important or perhaps if I give you money.

    Plastic screwdriver? Breaking one? WTF are you doing with them? I’ve never broken one… at least, while trying to use one as a screwdriver.

    perhaps I am increasingly starting to write in English with any combination of Dutch, German and Scandinavian grammar and Chinglish/Engrish added to that – which seems to be an unavoidable consequence of working with electronics, computers and sorting out problems/defects (such as the air conditioner at work starting to make water last night).

    The “bigger” laptop is a newer Intel Core I5-3210M 2.5 GHz with GT 440M graphics, 8GB RAM (upgraded from the stock 4MB) a wider screen and built in numeric keyboard; which is of course superior in operational use compared to two old netbooks. Hence my desire to quickly fix it – I just referred to it as a “bigger” laptop as not everyone here is a computer techie (even if others might like sound equipment or hi fi).

    The implement suggested to spring the latches is a “non marring plastic screwdriver”. I’ve never found one in CPC / Farnell yet, possibly I’m not looking in the right place. They are sometimes used to adjust trimmer capacitors in RF kit but I don’t do that naughty stuff any more these days and possibly half the worlds entire stock of these is in Kuala Lumpur, issued to an army of young apprentices realigning and repairing every bit of comms kit on the Malaysia Airlines fleet.

    that would also explain how NXP Phillipines got cleared out of big mosfets just after MH370 went down….

    A chopstick works equally well for this purpose though (and if made of sufficiently insulating material refocusing CRT monitors, though that is a long time ago now..)

    PS: That bit of C code actually compiles and works on a Raspberry PI (I’m not yet sure what the warning means), had expected it to segfault or do something else random…
