Toshiba Satellite T2100/CS/CT
The Toshiba T2100, T2100CS, and T2100CT are a series of 486-based laptops that were released in 1995. The T2105, T2105CS, and T2105CT are the exact same laptops, with the only distinction being that the 2105 models shipped with more included software.
Some of these have Satellite branding on them and others are just "Toshiba T2100CS" or similar.

Common Faults & Maintenance
Hibernation Battery Leaks
The NiMH Hibernation/Reserve battery in the T2100 series is highly prone to leaking and should be removed ASAP to prevent corrosion damage. I believe the battery sits somewhat far from the motherboard though, so these aren't dropping dead as fast as some other Toshibas are.
Capacitor Failure
This isn't 100% certain, but I believe there are ELNA LongLife series capacitors inside the T2100 somewhere, and these are highly prone to failing and leaking in machines just a few years older than these are. I'd highly recommend checking for them and replacing them if you find any.
