Battery Failure: Open Thermistor
Hello everyone. Yesterday my MBP rebooted randomly and showed my battery status to "Replace Now". It now shuts down when unplugged from the AC Adapter, and will not boot from battery power. These are the stats from System Profiler:
Model Information:
Serial Number: <<redacted>>
Manufacturer: SMP
Device Name: bq20z451
Pack Lot Code: 0
PCB Lot Code: 0
Firmware Version: 702
Hardware Revision: 1
Cell Revision: 3224
Charge Information:
Charge Remaining (mAh): 5633
Fully Charged: No
Charging: No
Full Charge Capacity (mAh): 5960
Health Information:
Cycle Count: 376
Condition: Replace Now
Battery Installed: Yes
Amperage (mA): 0
Voltage (mV): 12758
Clearly the battery is still fairly new, with a good amount of capacity and cycles left.
Running TechTool, the battery health check shows 1 failure: Open Thermistor. I have opened up the case to inspect the circuits and found no loose connections or corrosion anywhere (I have never had any spills on the laptop).
Also, running a sensor check in TechTool shows Battery TS1 and TS2 to be at 32C and 29C, respectively, and Passed.
I have tried doing an SMC reset to no avail. Anyone else know what I can try? Or am I better off just replacing the whole battery? Just seems wasteful to replace it given its cycle count and capacity.
Is this a good question?
