Problem
Service is aware of an issue, identified in the 1st 200 NPI Analysis of the all GSM Triplets models, with the Neptune LTE IC. A large percentage of the customer returns, returned with complaints of “Power Down in Standby” and “Phone Powers Down” were found to display the following symptoms. The unit will power down upon entering Sleep Mode when powered on using a battery. Analysis revealed the failure was caused by a faulty Neptune LTE IC where the Neptune’s PLL circuitrythe divider circuit in the PLL circuit is getting corrupted when the part is in sleep mode. During normal operation the Neptune will wakeup periodically as part of the operation of the phone but it is during this wakeup mode the failure occurs-the Neptune goes to deep sleep mode and then completely shuts down.
