SAVER_UNEXPECTEDSHUTDOWN
SAVER unexpected-shutdown bucket for SAVER_UNEXPECTEDSHUTDOWN
SAVER_UNEXPECTEDSHUTDOWN is bug check code 0x0000F012.
This bucket records an unexpected shutdown condition in the SAVER diagnostic family. It is not enough to explain the shutdown by itself; power, thermal, battery, bug check, and WER evidence must be correlated.
How to read it in a dump
- Treat this value as an internal diagnostic bucket from the Windows SAVER family, not as a classic blue-screen stop code with public parameter semantics.
- the useful evidence is the dump type, WER bucket, triggering process, provider-specific data, and event-log context around the capture.
- the symbolic name narrows the subsystem that requested capture; it does not by itself identify a defective driver or application.
What to check
- Check Kernel-Power, thermal, battery, firmware, and previous bug check records.
- Determine whether the system lost power, bug-checked, reset, or was forcibly powered off.
- Preserve event logs before repeated restarts overwrite the evidence.
