I have an (at least) six year old wireless keyboard and mouse (Mouse is the Mx700) keyboard came with and they're pictured at the end.
Up until a few weeks ago when I changed a few things the keyboard had an amazing record of battery life it had some basic Duracell batteries in it that were almost a year old.
Now it's consistently not operational, flat batteries (trying other Duracell and Toshiba standard batteries, and newer rechargeable varieties; Enveloop, EverFast, DoCo, DuraCell (ranging from 1500mAH to 2800mAH).
The following has changed things have happened:
- I stopped using the mouse MX 700 (put away no batteries)
- Now have a G700 mouse connected.
- Reinstalled operating system (still Windows 7)
- Moved the receiver 30 cm further away. Line of sight still good.
Could the mouse have been assisting in relaying the signal because it's closer, and thereby taking the power hit (it had horrible battery life as it aged). Now that it's no longer on the desk, keyboard has to communicate further?
Before I spend some time trying to diagnose this problem does anyone have any obvious suggestions?
- Interference from new mouse?
- Or not worth discussing could just be age of the keyboard?
What I'll try first is brining the sensor closer again.
What hasn't changed:
- Usage of the keyboard is consistent
- No other possibly interfering devices in the room.
