Yes！I just doing like this.
But I this work only fix my camera can not recharge the battery.It still has some problem in battery drain issue.
When I recharge my camera battery to full，after a day（not open it），it will empty.
I think something still run after the camera power off.Because if don’t remove charging，it still has 130ma to thecamera，even when I remove the battery，it has 80ma to fill in the camera.
I think maybe some bugs in firmware ver1.90，it make camera not in real sleepmode.
