Foreigners attacked 3 of my 4 yesterday (not only a problem of Bluetooth) keyboard

Three of my Apple keyboard (A1242-2 and 1-A1314 Bluetooth stopped working at the same time, leaving a very old work M2452 (USB).

.

Try a pram reset, (5 times) produces no double chime, just a normal restart smoothly.

.

The Bluetooth keyboard is dead. I tried new batteries, using the displayed codes, but it is not even at all.  Tried 10 times. (I used a procedure that works until today to remove keyboard preferences and configuration panels, then find the keyboard... but now it does not. Exchanged all USB ports for devices (keyboard and a trackball), but it doesn't seem to be a problem USB "stall".

.

I trashed "com.apple.Bluetooth.plist" and rebooted w/usb alone.  Not good

.

I have read many workarounds for the problem of Bluetooth solutions and they usually work after trying slightly different variants. But it is troubling.

.

Anyone have any ideas on what happened?

.

Thanks a lot for some advice.

You have another Mac or an iPad or any PC with Bluetooth, you can try with?
