Q: MBP randomly Shutsdown with previous cause -103
Hi,
I have a MBP 2007 with a replacement battery. The MBP shutsdown with no warning to a off state. On restart
syslog -k Sender kernel | grep Previous
reveals
Jul 6 14:13:31 localhost kernel[0] <Notice>: Previous shutdown cause: -103
The MBP is not running on the battery, it's running on a MagSafe connector connected to a Display. The battery has 1 cycle, is fully charged
Charge Information:
Charge Remaining (mAh): 4222
Fully Charged: Yes
Charging: No
Full Charge Capacity (mAh): 4245
The cell voltages just before the shutdown (by logging ioreg -n AppleSmartBattery | grep CellVoltage once per second were)
"CellVoltage" = (4083,4118,4078,0)
The Cell Voltages were stable and the ioreg is currently reporting

Did a buy a dud replacement battery ?
Are there any non dud replacement batteries for a MBP 2007 any more or is the only option to bin the laptop ?
Could the problem also be caused by a faulty MagSafe power feed from the LED monitor ?
(I have already reset the SMC)

Discovered that the MagSafe connector from the LED Display was showing up under a System Information ->System Report -> Hardware -> Power as
| Connected: | Yes |
| ID: | 0x0000 |
| Revision: | 0x0000 |
| Family: | 0x0000 |
| Serial Number: | 0x00000000 |
| Charging: | No |
But a 85W Power adapter brick showed up as
| Connected: | Yes |
| ID: | 0x0100 |
| Wattage (W): | 85 |
| Revision: | 0x0000 |
| Family: | 0x00ba |
| Serial Number: | 0x006ce428 |
| Charging: | No |
After following the instructions at Apple Portables: Troubleshooting MagSafe adapters - Apple Support and cleaning the LED MagSafe plug it now shows up in the System About as (and the LED on the MagSafe adapter works, so probably the earth pin had a problem)
| Connected: | Yes |
| ID: | 0x0100 |
| Wattage (W): | 85 |
| Revision: | 0x0000 |
| Family: | 0x00ba |
| Serial Number: | 0x00778b8c |
| Charging: | No |
(note different serial number)
Since doing this no random shutdowns (5h) where previously several in the same time period.
In which case it means the -103 shutdown cause means that there was a drop in voltage detected by the SMC controller on either the battery or the Mains Power Adapter supply. Will leave the Laptop on overnight to verify this behaviour.
