An old machine but it was free! I am trying to power it up but no go. I have plugged into mains supply. Under the main screen is a small LCD display which shows 4 batteries, each one lights up in succession, left to right. I presume that indicates charging ? When I press the power on button, there is a click and some power on noise and in the LCD display a little 2 pin plug symbol appears briefly but then machine goes off. Any ideas ?
