Hi Charles, > I'm using the CVS version of libs2 and utils2, with my MX900. I have the > impression that the MX900 batteries don't last very long between two > charging cycles (2-3 days). Can other here confirm this ? I don't have make stats, but I will do and keep you informed. But I think I'm charging about 1 time per week. Try with other batteries, as it seems some batteries in the Logitech devices has problems. > I must explain that I use my MX900 without the docking (with a laptop > underway), so I only dock the mouse to load it when it blink red. Same for me: I dock only when it red blink. Good day. Olivier -- Olivier Bornet http://www.smartdata.ch/ Olivier.Bornet@smartdata.ch SMARTDATA SA GPG key ID: C53D9218 CH Martigny/Lausanne
