Went to give this a go last night but. Last time I tried it I had 2 other Airs on my shelf with the same logic board that I pulled the bios from, I now dont have these and stupidly diddnt save the bios dump to the PC. Do you have agood bios for this I could try please? Thanks in advance,.

That should keep me busy :ROFLMAO: II tried to try a fresh bios but I just keep getting a weird error message on the madusa when tyring to write a clean bios file.. Seems to read it OK. Have you encountered this before?

Still NO video on internal or external, USB has power but no activity.

Keyboard arrived and this fixed this problem, Works perfectly and with backlight, But spacebar is missing, I did try to swap over the one from the original keyboard but it just keeps dropping off, This seems impossible! Have you any tips on swapping a spacebar on one of these butterfly keyboards?

Going to order from Harold today! And get a couple of push buttons., thanks ALL_SYS_PWRGD and PLT_RESET_L both at 3.30v with fan spinning.
