Help, HP Folio 9480m Charging (Amber) led blink 8~9 times

Help, HP Folio 9480m Charging (Amber) led blink 8~9 times and not power with Adapter only.

It can power with Battery but won't charge battery.

I've tried different Adapters, still same problem. MOSFETs close to charging IC (BQ736) seem to work well.

Check voltage on the identification pin when the charger is plugged in.

Thanks. I've fixed it already.

I noticed 2 bad resistors which i replaced.

The photo attached shows the Resistors I replaced. The schematic name is different but fits perfectly in that area. Component names corresponds correctly.
HP Elitebook 840 G1 and HP Elitebook Folio 9470m are very similar to HP Elitebook Folio 9480m.

I hope it helps others facing this problem
