“lost connection periodically I have 3 rocketfish Bluetooth keyboards and 3 Bluetooth mouse connected to a Win 7 Pro machines. Sometimes it works fine, but other times I cannot wakeup the machine with any of the Bluetooth devices. I have to unplug/plug the adapter to make them connect again. I have installed the driver from boardcom and there is no built in Bluetooth adapter. I have turned off the sleep/hipernate mode but the connection is still not permanent. Thank you for the advice.”

After doing some research, this is a either a Windows issue or an issue with your particular computer. There seem to be a variety of reasons that this happens. You may be unable to use Bluetooth devices to resume operation from certain power management states (such as "suspend" or "hibernate"). In some low-power states, the wireless receiver may be unable to receive information from the Bluetooth devices. To resolve this issue , follow these steps: Open the Keyboard control panel item. Click the Hardware tab, and then click Properties. Click the Change Settings button Note This step requires Administrator access Click the Power Management tab, and then verify that the Allow this device to wake the computer is enabled. Click OK, and then click OK again. Note If your computer does not support Advanced Configuration and Power Interface (ACPI), the earlier steps may not be available. In this case, you have press the power button to wake the computer. If you cannot resume computer operation by using any of these methods, you may have experienced a system problem.
