I have an ancient Escom KT50-MNB-I (Paradigma) laptop, which did have a knackered power-supply module, which I fixed, so now it has power, however I get no life apart from the fan running and the battery charging. The cpu (mobile 486) is fine, so I am wondering, what is frugged? And how can I tell? Memory too ancient to test in another machine, graphics card likewise, no bios beep, but that could be due to faulty memory, mobo integrity unknown. Power and reset buttons cause very slight shift in mobo voltages pretty much everywhere. Unfortunately I don't have a manual to tell me what is ....normal.
It seems a shame to junk it cos it's a funky little machine, when it could be something simple like a discrete component causing the fault. Suggestions, anyone?
