Hi!   The laptop I am using is a Medion Akoya P7628 (MD 99280). When i play a game the battery icon "flickering" charging/not charging. The strangest part is this: it begins charging fine normally when it is under zero load (idling) but as soon as I scroll a webpage or launch a game, it flickers. also even when the charger is plugged in the battery discharges slowly over time.   The charger im using is the original charger ( FSP090-DVCA1     19V===4.74A    90W ).   Many thanks in advance ...
