AX201 bluetooth drain power when sleep in Windows 11
my notebook only supports S0 modern standby mode but everytime in sleep mode the bluetooth device drain too much power.is there any workaround?
- i tried to fresh install the latest Windows 11 Pro 23H2 today and seems that the problem is gone:)
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.
