I have in my home a Microsoft wireless keyboard which uses 3 AA

last for 7 or 8 months. For some strange reason, I'm now changing them
monthly.

Recently, I was away for a week and the system was completely shut down.
When I returned and booted up, the keyboard was lifeless. I tested the
batteries, and they tested completely and totally drained on my meter.
That's unusual, because they usually test just weak when I replace them.
So, while I was gone and the system was off, something drained the
batteries completely.

At first, I assumed it was the keyboard, so I replaced it with another
one of the same model, an older one that I still had on hand. Same
result, one month. Does this make sense to anyone? Thanks.



Hi,
It may not be KB problem.

The KB is the only device connected to the batteries and is solely
responsible for battery drain. Like it or not, it's time to switch
brands.
