Re: Medion MD 96015
if you have a removable cmos battery, remove that for awhile, not to be confussed w/ the system battery.
...nothing at all on the display?
...no blinking lights?
you might want to unplug from the AC and remove the system battery. Then remove alll the RAM. Assuming you do not have any built in ram on the mainboard, when you plug in your notebook and switch back on should complain about not finding ram in the form of beeps or an LED(s) blinking...for most notebooks. Don't forget to remove all power when putting the ram back. You ight want to fully dissassemble the notebook, then rre-assemble ( i fixed some notebooks that way). Dell D600's had little flat pieces of spring steel that would make contact with the notebooks ground as the mainboard was installed , after time some that were not solder on good would come lose and tilt, grounding nearby circuitry ...giving the same results you are seeing...although I have to say sight unseen it sounds like the motherboard has gone bad.
