I am still alive and working on the project, mainly I have been messing around with this idea for the keyboard light, and generally just trying to optimize the 3D model for the bezel.
Something I have noticed is that I can hear a slight buzz from the onboard speaker and headphones when volume is turned up to full and no sound is playing which is most likely originating from the DC-DC converters. I am going to look into that some more and try to cancel that out with some better filtering on the power supply side of things. It seems that even an unmodified PC110 has this noise when the volume is turned all the way up, even with no inverter connected at all.
The BIOS patch is about ready, it works properly I have just been working on proper safeguards (making sure on a/c power and battery is charged etc).
Here is the current revision of the board. I was not paying attention and I ran those traces too close to that mounting hole, not a major issue as the screw goes into plastic and is not tight enough to damage the solder mask, but still not proper I will move it. DC-DC converts of course are on the back as seen in some other photos.
Here is the keyboard light in action, on one of them is working as I broke the other one and I was lazy to deal with it. Maybe only one LED is needed (if any really).
And here is the 3D printed bezel poorly painted just to see if it would block the light (it does). Feels strange without the IBM logo.
And here are just some random pictures working of 3D model progress.
