I have just done something that I have to post here.
It was 11 am and I am in good shape mentally and physically. I have an HP Pavilion dv9000. The power supply was stolen by a worker (along with two other old laptops). I tried to get a replacement, and even ordered one. When it was delivered, the plug was not the right size. I could not see a proper replacement on the internet. These things are very badly specified. An after-thought.
I saw a universal power supply at the hardware store and bought it. 100W with output switchable from 12, 15, 16, 18, 19, 22 and 24 volts - and a 5vdc USB port. The input was 110 vac to 240 vac and also 12 vdc from a car lighter socket. It had 8 different adapters.
So I tried the one that seem to be the right fit. The last thing I wanted was to break anything. I took the adapter out of the rubber holder and I was very happy that it fit relatively easily. I tried it two more times because I wanted to see if I could sense the fit of the inner pin. I also rocked to slightly and gently to feel the fit. Great.
I then assembled the adapter on the power supply, selected the correct voltage and then tested the adapter from voltage and for polarity with a voltmeter. All good.
And then the adapter would not fit. It seemed oversized. I went and got a set of drills and my vernier.
The inner pin was the the size of a 1/16inch drill bit. The outer sleeve of the adapter was 5.45 mm. The laptop socket sleeve was 4.95 mm.
How an earth did I fit a 5.54 mm plug into a 4.95mm hole?
It is possible the hole itself is 5.5 mm and the metal contact fingers are slightly less. I tapered the plastic on the adapter to see if that would help. But it seemed clear that the metal insert in the laptop is 4.95 mm. I have a 5.45 mm metal adapter hitting the 4.95 metal sleeve on the laptop.
Even pressing the vernier hard got me to 5.0 mm in any position.
My initial feeling was that I was hallucinating. But I know what I did. And I took it slow and carefully. Is this a glitch in reality?
So ironic that I have said that posters here are trying to fit a square peg in a round hole and here I fit an larger round peg in a smaller round hole. I thought about temperature difference but it would not accommodate such a difference. Besides both were in the study the whole time.
I can just imagine the responses. I can assure you it is not me messing with you. It might be God.
