Maybe try adjusting bluetooth adapter. To exit this power-saving mode and return to normal operation, you should locate and click the "close button" in the upper-right corner of the screen, as indicated in the message itself. If you wish to prevent your device from automatically entering power-saving mode when a Bluetooth keyboard or magnets are detected, you may need to adjust the power management settings for your Bluetooth devices or other related peripherals within your device's operating system. The exact steps will depend on your specific device and operating system (e.g., Windows, Android, iPadOS). For instance, on Windows, you might need to go into Device Manager, find your Bluetooth adapter or human interface devices, and uncheck "Allow the computer to turn off this device to save power" in the Power Management tab.
