Well i did stumble on a problem that my M11xR1 cannot be on using battery power alone...
so wat i did, i open them up and disconnect the battery terminal and reconnect it back.
now back to normal de.

After the fix of my hinge last time ...up till today no sign of hinge issue here...let just hope it stays that way..

BTW my M11x no more warranty de so i open them up myself..
