Frequently Asked Questions
What data is lost if I remove the main power cord?
All user data on the memory (DDR4, CML-S Refresh, RKL-S) is destroyed.
Does the system retain data in S5 soft off state?
No, S5 is the soft off state. No data remains in any component like cache or memory.
What is the supported ACPI power state for Windows 10?
Windows 10 supports S3 (suspend to RAM) state.
How much volatile memory does the USB controller contain?
The USB controller contains 8 KB of SRAM which is volatile.
