If the mouse lies motionless for any length of time (it can be 5 seconds or 1 minute)
it may turn off and not turn on again until I remove the battery for a couple of seconds
I tried:
-Buy other batteries
-Install different versions of synapses and just work without it
-Reinstall Windows
PS:
-It can turn off when the battery is fully charged
-The transmitter is on table with mouse in 4 inches away from the mouse\ 2.4 mode
-The power save setting in the program is set to the longest possible shutdown
