Powered on three of my retro Toshiba laptops to make sure they're still functional - a Toshiba T1910CS (486-33, 4 MB Ram, 200 MB Hard drive, passive matrix colour screen), my 430CDT (Pentium 120, 32 MB Ram, C&T Video, ESS688 w/real OPL3!), and my Tecra 500CDT (P120, 32MB Ram, C&T Video, CS4232 w/real OPL3) and thankfully all seem to be as they were when I last booted them.
The 430CDT has a couple of quirks - seems to run into issues with Duke Nukem 2 (plays and then freezes randomly) and the headphone jack doesn't seem to work, but the onboard speaker does. I'm pretty sure I pulled the batteries from this one -they're easy to get to on this one.
The T1910CS is near mint (save some marks from storage, should be able to clean right off) and seems original, down to the 200 MB hard drive. I haven't opened it yet to remove the batteries, mostly because it's in such nice cosmetic shape and I've never been the best luck at cleanly opening and reassembling retro laptops. Probably should do it soon though.... Everything works on this one too, right down to the floppy drive at last check.
The 500CDT looks really rough, cracks in the palm rest, some missing case bits at the edges.... but it 's the one that works best for me. The only issue I'm aware of is that the headphone jack works but doesn't always mute the onboard speakers. Pretty sure I pulled the batteries from this one already too.
Unfortunately my Toshiba external floppy died a while ago and I was unable to resurrect it - and the 430 and 500 won't boot from CD, so I need to move the drives out to other computers when I want to do re-installs which sucks.
