Today I've learned that nothing is as simple as you think it's going to be.
My friend Lorraine is away for a few days and I'm feeding her cats. She asked me to fit a new keyboard and mouse to her computer as she'd amanged to squash all the pins in the plugs of the old ones when she thought the plugs screwed in.
So I arrived this morning and found a note asking if I could fit a plug to her speakers as well as she'd used that plug on her TV set.
So I fitted the keyboard and mouse, fitted the plug, booted the computer and found that the socket for the monitor had come adrift of the motherboard and won't go back on again easily.
So I've now salvaged a socket from my old computer which I'll try and fit later.
I'd only just got the computer working again after her rabbit ate through all the cables.
