Installing the laptop motherboard
Getting down to the nitty gritty : installing the electronics.
I had to carve a bit out of the inside of the case so that the motherboard would fit. Unfortunately there was no way I could get it to fit with the dvd drive because the pcmcia serial port sticks out so far on the other side. No big deal. Who uses DVD drives these days anyway? Especially on Linux.
Other things to consider.
1. A power socket needed to be installed on the exterior of the case.
2. A power (on) button needed to be installed on the exterior of the case.
3. Air vents for the cooling fan.
4. USB Ports needed to be installed on the exterior of the case.
5. erm… speakers?
6. This is a biggy. The touchscreen controller needs to run on 12v. The laptop’s input in 19v and there is no 12v source on the motherboard!
The power socket was harder than expected. I tried to unsolder the original power socket from the motherboard, but Acer must have used some kind of high temperature solder or something since my soldering iron couldn’t melt it! In the end I accidentally broke the socket altogether.
But that’s no problem for an enthusiastic hardware hacker! I managed to pull a power socket out of another device which was the right diameter for the plug, though the little positive pin in the middle was fatter than the original so the plug wouldn’t fit, so I salvaged the middle pin from the original port and managed to swap them over. This worked well.
I then soldered two cables to the underside of the original socket connectors on the motherboard and soldered them to the new socket, which I then installed on the exterior of the case.
A bit rough around the edges, but I’ll fix that later.
