SPLIT 13 X2 screen not turning on and not charging

i recently bought a split 13x2 mo1otu from singapore, and the screen porton is not turning on and not charging.

here are some information:

1) both docking station and screen batteries have been drained recently

2) when the power adapter is connected to the dockng station, an orange light is seen. (charging normally)

3) when the same power adapter is conected to the screen, no orange light is seen, ie the screen is not receiving power.

4) the screen portion will not turn on, whether connected to the dock or not.

cheers, yanheng
