Part Number: BQ30Z554EVM
Dear community,
We are repair service for laptops and have an Asus N550J in the repair.
Until we have been waiting for the spare parts for this laptop, the battery C41-N550 has discharged and will no longer start.
Microcontroller bq30z554 is sealed and can not be calibrated.
It would of course be easy to order new battery, But for engineers it is not an option :)
The battery has only ran 81 cycls ...
I would like to know there is a way to unseal the controller, or we should order new IC?
With default unseal code it does not work,
I have heard there is a master code for such cases?
Any help is welcome.
Thank you in advance!
