To ensure optimal performance and long-term reliability of your Stonebook Edge-R device, a critical firmware update is now available.

This update addresses system stability improvements.

Why This Update Is Important

The latest firmware version includes targeted fixes and enhancements designed to alert and mitigate potential isolated system behaviours in field deployments.

Key improvements include:

  • Enhanced power management to mitigate rare anomalies during sleep/modern-standby/hibernate/off power modes.
  • Improved USB stack handling to detect and improve control of rare peripheral anomalies during active mode.

These changes are part of our ongoing commitment to deliver a robust and reliable computing experience, especially in environments where uptime, predictability and longevity are critical.

Who Should Apply This Update

All owners/users of the Stonebook Edge-R devices are strongly encouraged to apply this update.


How to Update

Prerequisites (Applies to all methods)

  • Ensure the device is plugged into AC power, updates will not proceed while the device is using battery power.
  • Confirm the target BIOS image is correct, it should be version SP41MD103_STE_V15.bin or later.
  • Backup critical data if needed (BIOS flashing is low-risk but precautionary).
  • Identify current BIOS version if audit logging is required.
  • Suspend BitLocker is enabled.
Warning: If Microsoft BitLocker is enabled on your device, you must suspend it before applying the firmware update to avoid being locked out of your device by BitLocker recovery mode. It is also recommended that you verify your BitLocker recovery key is stored safely on removable media, stored in your Microsoft account, or Stored in the domain account provided by your employer / education institution.

More information and guidance on how to perform this task are available directly from Microsoft.
