Where Do the Mouse & Keyboard Go?
There have probably been many times where you've needed to disconnect your computer, then reconnect all the cables afterwards...without good lighting to see behind the tower or a flashlight nearby.
Here's a useful tip for figuring out where the PS/2 keyboard and mouse plugs go. Most of the time, the mouse is green and the keyboard is blue, however, they can sometimes be hard to distinguish in the dark.
All you have to do is remember this: the keyboard PS/2 jack on the motherboard is always closest to the motherboard, while the mouse jack is furthest away. So, looking directly at the back of the case, the keyboard jack is always on the left, while the mouse jack is on the right.
