Charge ok but didnt start... I dont understand!

[rickys]

Hello everybody,

I have a strange problem with with switch. it didnt want to start. It charges well (no problem with 15V and 5 V chargers) but i didnt have the picture with the battery which says that it is charging and when i push the power button no reaction.
I test continuity on the MB but i didnt find any shorts on P13USB,M92T36,BQ 24193 and max chips.
Anybody has an idea where to search please?
I I would be tempted to change the m92t36 because i dont have the charging picture when i plug the charger but i am absolutely not sure of me.
Could it be a good idea to start by changing it?
Thanks a lot.

Did you try docking it and see if it show and image on the TV? Also, were you using autoRCM?

Hello,
Thanks for your answer. It is not in RCM mode i verify with TegraRCM. On the dock no reaction too. My principal problem is that i didnt have the little battery which appears when i plug the charger on the switch. So i think it is a hardware problem but i dont find where...

I would honestly try to disconnect the emmc and see if it enters RCM then.
