I ordered a keyboard replacement. This thing is a serious pain. The power switch is directly part of the keyboard. Under that button is nothing but silver paint for the contacts, which had firmed a crack over time.
The worst part? Above the keyboard is a thin piece of sheet metal. It is “riveted” on by melting a fee dozen plastic standoff that affixed the metal piece by melting the tips of them. I spent an hour carefully popping them off with a screwdriver. The replacement keyboard fits (good news!), but I have to carefully use a soldering iron to melt the tops of these pieces back into “rivets.”
On the plus side, I have upgraded the RAM and added a hard drive. If it POSTs at the end of this, I will have 16gb of RAM and a 4 to add, which will let me ditch the external drive.
