My day just got worse and worse.
After discovering that my long lost girlfriend from 46 years ago has turned into a horrible eco-loon grandma, my laptop fell out of my bag onto the car park as I was unloading three bags and smashed the screen. A drop of about a meter onto a corner of the case didn't do it any good
Oh - no problem, says I - I have a good screen on the previous one with a non functioning keyboard after it got wet. I knew keeping the corpse of the old one would come in handy.
So after eating some food, I set about cannibalising the good screen out of the old laptop; removing the smashed screen from the newer one; fitting it, and then putting the whole thing back together.
All was going well.
It fired up, the screen looked pretty good, and I tested the keyboard before fastening the cases together. It worked as did the cannibalised screen, but once I put all the screws in, securing the case, pressing number '1' on the keyboard, caused a cascade of random numbers to appear.
I had it apart and together twice more before I realised that the slightly bent aluminium case is causing some error when I screw the damaged part snugly to the base.
I had thought that the ribbon cable for the keyboard had been dislodged on assembly, but it hasn't. I got it to work by leaving out one of the case screws so that there is a tiny gap at the right hand side of the keyboard base and the lower case part. If I put that screw in and pull the case neatly together the random number gremlin re-appears.
It is working now and I am using it, but I will probably have it apart again and investigate what the issue is. Even if I get it sorted, I am going to need a new one, because I can't be bothered to be fiddling about with this one now.
