Solve bluetooth mouse disconnecting under Windows

After buying a new mouse, a Microsoft Sculpt Bluetooth Mouse, and connecting it to my Lenovo E440 laptop, i noticed random disconnects a few times a day. These were not normal, the mouse was not working even after a button click.

Windows event viewer message : Bluetooth HID device either went out of range or became unresponsive.

Searching the forums only revealed that most people with the same problem have a Intel N 7260 wireless adapter.

Things I’ve tried :

  • Install : Mouse and Keyboard Center 2.3 64-bit
  • Update wireless Lenovo drivers from official site.
  • Update laptop BIOS from official site.
  • Disable power management for bluetooth adapter.
  • Update wireless drivers from Intel website. This was a big mistake, my bluetooth adapter was not recognized anymore in device manager. I had to do a system restore to correct this.

The only thing that worked was to disable power management for the wireless adapter (same for generic bluetooth adapter).

Disable wireless power management

Bluetooth device instance path in device manager : USB\VID_8087&PID_07DC\5&340F1A3E&0&7

Tested on Lenvovo Thinkpad E440 with Windows 8.1 PRO 64bit, Intel Wireless N 7260, and Microsoft Sculpt Bluetooth Mouse.
