Derek what kind of bluetooth device is this? It seems to me like a simple idle process which also looks like its using 99% of your cpu but its just the opposite. You got your work cut out for your though since it is a notebook so ask yourself does this notebook run significantly longer without this bluetooth device plugged in. After I get that nailed down we should have no problem I am definitely not gonna let you loose sleep over a bluetooth situation thats not how we build around here my friend.

    It's the Bluetooth Radio which is a part of Intel AX201 card.and I just wonder why it consumes so much battery power when the notebook get into modern standby sleep(10% in around 2.5 hours and even drain the battery to death).As i understand the bluetooth devices should be in sleep mode also when the notebook into sleep however it drains the battery power all the time.And if i disable the Bluetooth Radio and get the notebook into sleep mode then only 10%-12% each 24 hours will be consumed which is much reasonable.

      Im tracking now Derek. You seem familiar enough where i can make this short. Run Device Manager find your intel AX201 card that is in bed with the Bluetooth radio right click it then click properties and the far right tab is power managment which should give you two options. 1. let the computer turn the HID off when not in use or 2. allow the device to wake the computer. If you dont see this option "highly unlikely you wont" then qualify your situation with a few more questions so I can driil down to the root of what we will soon find not to be an issue at all. I like that you have done your research you can tell it in your post.

        Thanks for your assistance my friend.I didn't see the "power management" tab in AX201 properties.And i have tried below steps but none of them works.
        1. Check Power Settings:
        Ensure that power settings are optimized for energy efficiency. Go to Windows power settings and adjust the options for sleep mode.

        2. Update Drivers:
        Check the manufacturer's website for updates to the bluetooth drivers.

        3. Disable USB Selective Suspend:
        In some situations, USB Selective Suspend can interfere with Bluetooth operation during sleep mode. You can disable it in advanced power settings.
