I suspect this is capacitor related due to the smell, and I think it's coming from the power adapter and not the computer, but I have a Toshiba T1200 that no longer powers on at all. Has anyone had any luck restoring these?

@techknight has been recently restoring something similar, I'll ping him on the discord.

Yeah any T1200 needs the dc/dc board in the computer recapped. This is a must on any Toshiba from this time. As for whether the power brick needs it, not sure.

The Toshiba T1XXX line are horrible for pissing capacitors everywhere, eating traces away and even blowing up transistors. I have worked on many.

The T1200, and especially the T1200xe is the worst offender. I have a pair of those and I have been unable to repair them. The power supply circuitry was novel for the time, but its complexity was its own downfall especially when cap juice gets everywhere and eats the board completely out.

The AC adapters are just as bad, yeah. I have not worked on AC adapters that old because i never see them with the machines, but the newer Toshiba PSUs for the T19XX series and T4XXX series are awful. They all need recapped.

Oh man, sounds like I have a piece of work on my hands here.

Any hints on the hard drives? Weren't they proprietary too?

Some of them were, yeah. The ones that were traditional IDE, Toshiba was notorious for hardcoding the BIOS to only work with their specific drive bundled with that machine so you need the expansion card which has an XT-IDE to CF solution.
