Battery And Current Calibration Test; Backup Capacitor Test - Sony Ericsson K630 Troubleshooting Manual

Battery and Current Calibration Test

Use the Phone with the ITP SW
Instrument settings for the Battery Calibration Test
Power Supply Channel 1 VBATT:
X Volt according to the Fault Trace SW Test Instructions:
Fault Trace SW-Logic-Phone Power-Battery Calibration and follow test instructions.
Limiter: 2A.
Power Supply Channel 2 DCIO/SEPI:
5.0 Volt
Limiter: 2A
If the test Is performed at the Core Level then use dummy battery according to the Equipment
List. If the TRS Fixture is used no dummy battery is needed.
Note: Maximal cable length between Power Supply Channel 1 VBATT and the dummy battery
or the TRS Fixture must be 1m. The cable must have a capacity for at least 16A.

If the test is performed at the Core Level then use dummy battery according to the Equipment
List. If the TRS Fixture is used no dummy battery is needed.
Note: The Power Supply Channel 1 VBATT must allow reverse current.
Note: Maximal cable length between Power Supply Channel 1 VBATT and the dummy battery
or the TRS Fixture must be 1m. The cable must have a capacity for at least 16A.
Note: Length of the Power Supply Channel 2 DCIO/SEPI customized cable must be exactly
1,3m.

Battery and Current Calibration Test - Backup Capacitor Test

Backup Capacitor Test

To perform this test use:
- Phone with the ITP SW
- Power Supply Channel 1 VBATT: Instrument settings: Voltage: 3.8V, Limiter: 2A
- Power Supply Channel 2 DCIO/SEPI: Instrument settings Voltage: 5V, Limiter: 2A
This test should be preformed in 3 steps:
Step1:
Measure the voltage at the Backup capacitor by using Fault Trace SW- Logic - ADC Values –
Read ADC Value (Reading 1).
Step2:
This step should be done 30 seconds after Step 1. Measure the voltage at the Backup capacitor
by using Fault Trace SW - Logic – ADC Values - ADC Channels – Read ADC Value
(Reading 2).
Step3:
Compare the difference between Reading 1 and Reading 2 with the reference table below. If the
Reading 1 value is between 50 and 680 go to Interval 1, if between 681 and 800 go to Interval
2, if between 801 and 880 go to Interval 3 and compare with the Reading 2 – Reading 1 Min and
Max Limits.
Reference Table:
Absolute readout Reading 1
Reading 1 (Dec)
Interval 1 (50 – 680)
Interval 2 (681 – 800)
Interval 3 (801 – 880)
Note: The upper table contains the absolute limits for the readouts. The lower table contains
the allowed delta between the first and the second readout, separated in time with 30 seconds.
If reading is out of the test limits then replace C2217 Backup capacitor.
If problem is not solved then SL 5 Replace N2000 SL 4 Escalate.
