Digital HiNote VP710, Twinhead Slimview 3100C

[Adam Luchjenbroers]

I'm trying to obtain service manuals for the following two rather ancient laptops.

* Digital HiNote VP710
* TwinHead Slimview 3100C

Also, if anyone could oblige by providing me with the following two pieces of information:

* Is the power connector for the HiNote VP centre-positive or centre-negative
* How in hades do I remove the hard-drive from the 3100C, it appears to be stuck to the outside cover with no signs of a removal mechanism and I would prefer not to risk damaging either the disk or the outer cover with the flat-bladed screwdriver lever approach.
