Logitech POWERPLAY Setup Manual page 5

Battery does not charge to 100%
– This is by design, and is intended to minimize power emission
and optimize battery cycles . Mouse battery level will be
maintained between 85% and 95% while powered by
the POWERPLAY charging base .
White LED goes dim or turns off
– The white LED indicates three states: no connection between
POWERPLAY and POWERCORE (LED off), connection between
POWERPLAY and POWERCORE, but charging is not active
(LED dim white), and connection between POWERPLAY
and POWERCORE with charging active (LED bright white)
Can I use a different USB cable than the supplied one?
– No . POWERPLAY is designed to be used with the included
USB cable only .
Can I physically modify the POWERPLAY charging base?
– No . Do not cut, fold, roll, bend, or otherwise modify
POWERPLAY charging base . Doing so will void the warranty
and may damage the charging coil .
