Thx for your quick answer. I did'nt find a way to pick a good tension plot near MB jack DC 19.5v female adaptor and i'm not yet ready to disassemble the MB to look for any possible back access... But it can be possible that i have trouble with my multimeter (which always shows 0 between the 2 visable pins outside back the DC jack adaptor), as it shows also same null measure sometimes from the AC adaptor output itself ! I put a new 9v battery inside but that no measure problem arrise time to time. So I'm now waiting for a new multimeter !! I noticed Medion service shop have no DC power jack but an Power Switch Board "NBC POWER SW BOARD CLE V170RNCQ", so the jack is not the only power device, the keyboard "button" can have broken. Problem as arrived while P30 was on AC adpator with deep sleep form unix during 3 months w/o use. So i suspect also an empty battery now. With a new one just received and i think alternate juice provided, still no powering any fw & bios. So perhaps the problem can be that Power switch ?!? What do you think about that facts ? FYI : P30 has run a maximum of 3 hours from the first start, and now is bricked after 3 months unused ... no fire or overheat evidence once back cover removed, other pc drained from same wall and 3 month sleeping, only that Medion is concerned !
