    pc broke so I plugged my monitor via SP3 connection. Worked instantly. however wouldn't work in dock unless I plugged dock into electric, then worked fine. Question is, this will cause the SP3 to charge constantly so will this damage my battery?? Just wondering if I can continue to use dock for this or should I go back to direct hook up to SP3. Mine is i7 256 model. thanks again for all your help here for a newby.

    This should not significantly impact the battery. It is recommended to let the battery discharge once a month but a battery can be refreshed by doing several full charge discharge cycles successively even if it's been abused for a year or more. I have brought batteries back from 70% up to 95% capacity. Don't worry about it.

    I'm pretty sure they have power for the dock because there are active components in it that need to have power.
