Because of lack of maintenance of power generation equipment over a long period of time (decades), there isn't enough electricity in South Africa to meet the total demand. So now they've moved to scheduled load shedding that is not always well scheduled. Like there may be no load shedding for a few days, and all of a sudden out of the blue it will start again. And catch people unaware.
We were caught unaware again last night. At around 1:00 a.m. I was aware (while I was sleeping) that everything went dark. I didn't worry about it that much, but at 2:30 a.m. when the power came on, there must have been a surge or something as my computer started to make heavy sounds and the "on switch" was flashing like crazy. I turned the on switch off, waited a while, turned off the electricity at the wall, then turned everything back on again, but then the flashing continued again. I was almost sure my computer was in the process of dying. I tried again, and the same thing happened - a flashing switch and lots of whining by the computer - like three long whines and a short interval in between continuing without stopping. I then in desperation uncoupled all of the devices attached to the computer tower including the monitor, speakers, printer etc, took the computer tower to the kitchen, and then found an alternate power cord - just in case it was the cord that was the problem. And it turned out then that it was the cord as the computer worked OK with the alternate cord. The cord must have been fried when the power came on again.
You can't imagine the absolute relief when after I had re-attached all of the equipment such as speakers, printer etc again, the computer was working again - all of the attached devices as well. There was a slightly whining sound in the tower, but that worked itself out eventually by tonight - after the third time I'd turned off the computer during the day.
By the time everything was working at 4:00 a.m. my first step was to immediately create an emergency system disk. I have made regular backups before, but the "rescue disk" was dated to 2014 when I first got the computer, and I've never made a full "image backup" of the computer. I went for everything in the list of copies one could make in the Windows 7 Backup and Rescue Window. Fortunately everything was done by the next scheduled load shedding session at 9:00 a.m.
This was really scary. And I guess it is liable to happen to the best of us. I just wonder why it went for the computer cord and not for the printer or monitor cord as well. Like maybe there was already something that wasn't that good with the cord? I have a surge protector. All of the equipment attached to the computer also are on the surge protector - but only the computer cord was effected. I used to always leave my computer on, however now decided to have it as a habit to always turn off my computer at the end of a session. Hopefully that will help as the load shedding is going to be with us for a very long time.
Darn! I knew a lot of sad and weird stuff was going on in South Africa. But I never knew it was this bad! This entire situation seems very scary to even think of, I could only imagine your perspective living it!
As for the weird behavior you’ve experienced, I highly recommend completely unplugging any electronic devices that you’re not using. And the ones you are using, I recommend unplugging them as soon as the power goes out.
I aint no electrical engineer, but my dad (who is one) has always told us to uplug everything during a power outage as they could get severely damaged the instant the power goes back up. Not sure why that is, I’m guessing that the load as soon as they turn the power back on is significantly higher than normal, making it hard to regulate the output. A surge protector won’t be of much use in that case. Also, surge protectors work by sending the excess power to ground, so if they’re not grounded, they’re pretty much useless!
Thank you Post4VPS and VirMach for providing me with VPS9! But now it’s time to say farewell due to my studies.
