This is a mea culpa post, about a time I was very dumb with tech. Thankfully I didn't call tech support and humiliate myself, but I wasted far too much time on it... okay, here goes...
My boss got a gorgeous new HP lappy, the shiny black ones that look like they're polished like a grand piano. He asked me to get it set up for him - put in the battery, do the first charge, set up the Bluetooth peripherals - all very easy stuff.
My first problem, though, was getting it open. It was sitting on the desk in front of me, HP logo right way up, with the two unlocking buttons facing me. I pushed them. No luck. I tried to slide them, no luck. I tried twisting them. No luck. I turned to the manual, looking for instructions on how to open the damned thing, but they obviously thought it was so basic it didn't need explaining.
After maybe ten or fifteen minutes fiddling with it and reading the manual, something clicked in my head. I felt a mixture of relief, triumph, and utter humiliation as I rotated the laptop 180 degrees and easily opened it. The "locking buttons" I had been playing with were the hinges.
The problem was that the HP logo was positioned to be the right way up when the lappy was opened, and therefore had to be upside down to open it. I made the mistake of mentioning this to my boss, and it was a source of comedy for days afterward. Ah well.
