I have a transformer TF300T and have issue with the dock - it will not recognise it 99% of the time - sometimes it will but moving the hinge will then cause it not to recognise it.
Now - I have replaced the power/docking internal ribbon in the tablet (old one did have a crack in it) and have tried two other docks and the same happens.
the charging lead directly into the tablet works fine - no problems. Edit - every now and again it will go "bing" indicating its been reconnected and will then continue charging - this is without being touched - if i waggle the cable about nothing happens so do not believe it to be a physical issue - maybe wrong
I know very very little (read nothing) about android things so have listed below some details:
so was playing around with this again and have found that if a apply pressure to rear of tab just below Asus logo it will see the dock fine, when pressure released dock will not be recognised.
so am thinking if I insert some hardish foam or soft rubber inside the tab at this point it may solve this.
my question is does anyone know at this area inside is there anything that may be affected in doing this?
