When Windows 10 Professional shutdowns while on Battery Mode and with Turn on fast startup unchecked. Windows 10 encounters a BSOD with Stop Code DPC WATCHDOG VIOLATION.
Fast Startup Disabled
First, T495 came with Fast Startup turned on. However, I did not like the idea of using it so I turned it off. I wanted all running applications shutdown when Windows 10 restarts or shutdowns.
Blue Screen on Battery Mode during Shutdown
It took me sometime to figure out the condition that causes this error.
It takes about 5 minutes to complete the collection of error info before the laptop restarts.
How to Fix
I just turned the Fast Startup back on! With this, I no longer get the same error when I shutdown my laptop while on battery mode.
