Bluetooth wireless technology devices do not automatically connect after the computer returns from hibernation or sleep mode.
IMPORTANT: This article applies only to specific products and/or operating systems. Check Applicable Products and Categories for details.
There are default configuration settings that get triggered when the computer enters hibernation or sleep mode which can disconnect Bluetooth® devices, prevent those devices from automatically reconnecting, or prevent new Bluetooth devices from being discovered. This will occur even with devices that have already been successfully paired with the computer. Follow these steps to change the configuration settings and allow Bluetooth devices to remain active and connected even when the computer enters hibernation or sleep mode.
- As a result of making these configuration settings changes, you may notice that the overall amount of time a fully charged battery lasts before needing recharged is less than before the changes were applied. This is to be expected because the Bluetooth connections constantly remain active and will require additional power to do so.
