I recently purchased the Microsoft Bluetooth Mobile Keyboard 6000, and while being generally happy with it (despite the lack of dedicated home / end buttons) my main concern with it was that after just 8-10 seconds the keyboard seemed to go into sleep mode, requiring a second or so to wake up again. According to the Microsoft documentation the keyboard should not go to sleep until 8-10 minutes, so this behavior was quite unexpected.
It turned out that the issue was in the Thinkpad laptop. The default settings for the Bluetooth driver is to power down the Bluetooth chip to conserve power, causing the keyboard to become unresponsive after just a few seconds.
So if you too experience this issue, you can remove the lag by:
- Pressing the <Windows> button on your keyboard
- Type ”Device Manager” and press <enter>
- Open the “Bluetooth Radios” section and right click your Bluetooth driver (in my case “ThinkPad Bluetooth 3.0″) and choose “Properties”
- Choose the tab “Power Management” and disable “Allow the computer to turn off this device to save power”
Your keyboard should now be completely “lag-free” in daily use.
