File Request ACER Chromebook 13 CB5-311-T9XM

[CIL-Electronics]

If possible I'd like a full set of schematics for this. I have a problem with the headphone detection circuit, essentially it's not detecting any headphones put in. So need to identify the device D1 on the headphone sub-board as I believe this is faulty.
Thanks

H. I could not enter the MOBO model in the reqeust, it would not allow me to type anything in.
The numbers are:
Z3ENN LA-B551P
Rev 1.0
Hope that is sufficient.

Brilliant, thanks so much

You are very welcome

Any chance of PCB layouts for this as the schematic does not seem to tally with the PCBs in the Chromebook.

 

[Ahmad Kor]

we don't have another schematic for this model.

Thanks Mahla. From the schematic, I suspect the mic switching circuit, investigating.
