I noticed intermittent frustrating behaviour with my shiny new [easyazon_link keywords=”Dell Inspiron 7000″ locale=”US” tag=”bobmckay-20″]Dell Inspiron 7490[/easyazon_link] (awesome laptop by the way) when using it with my [easyazon_link keywords=”Microsoft Bluetooth mouse” locale=”US” tag=”bobmckay-20″]Microsoft Bluetooth mouse[/easyazon_link]. If I didn’t move the mouse for 5 seconds (even if I was typing and so the laptop didn’t power save), the mouse would freeze and take a couple of seconds to wake-up. Not the worst issue in the world but really annoying when you’re jumping between typing and mouse.
After investingating all of the usual power saving options you’d expect to to affect this (disabling Windows’ ability to make put a device to sleep to save power), it turns out the only way I’ve been able to consistently fix this is to delete the following entry in device manager and reboot:
This fixes it for me 100% of the time *but* the issue seems to come back after a round of updates so I’m hoping Microsoft will eventually fix this permanently (or I guess I could write a script to delete the entry on shutdown – a dirty fix if ever there was one).
To get to this device:
Press the Windows key on your keyboard and type Device Manager
Press enter to select Device Manager (or click it if you’re mouse hasn’t gone to sleep 😉
Expand Bluetooth and find the entry for Microsoft Bluetooth LE Enumerator
Right click on the entry and select Uninstall
Reboot your machine and your issue should be solved!
