HP Omnibook 2100
I've bought this notebook as damaged as I needed spare 
		parts, and I found that the only problem it has is with power connector 
		desoldered from board. I've used it as my Win98 machine until I got 
		Tecra 8100. 
		Tecra ntebooks were chosen because they had good quality-price ratio and 
		were easily accessible. The only negative thing with these laptops is 
		their pointing device: Toshiba stood long with trackpoint-only 
		notebooks, while other manufacturers started to use touchpads. But it 
		should be noted that for experienced user using trackpoint is as 
		comfortable as touchpad.

Unfortunately my unit has no HDD and its cable, so I can't install an OS on it.
Here you can find hardware servicing manual for it. Disassembly procedure is described there.
And HP still (2014) has support for it: Look here or in HP's suport website as they like to move stuff.
