-- Posted by NZ Guy at 10:59 pm on Jan. 7, 2009 For christmas I got a Logitech MX 5500 bluetooth keyboard and mouse. The mouse has just now started to move erratically and not smooth when I'm using it. Is that what happens to bluetooth mouses when the start to go flat? My old Genus wireless one would just cutout, but it was only RF. -- Posted by lalacakes at 10:59 pm on Jan. 7, 2009 they get worse. -- Posted by thegeek at 10:59 pm on Jan. 7, 2009 My Kensington mouse did that and it had nothing to do with batteries. Try re connecting it to the computer. -- Posted by NZ Guy at 11:04 pm on Jan. 7, 2009 i just unplugged the USB bluetooth dongle and pluged it into a USB extension cord to move it closer to the desk, it seems to have made it better. The battery meter on the mouse shows 1 bar out of 3, so it could be going flat. -- Posted by Stellar at 11:05 pm on Jan. 7, 2009 My roommate has one of those. The range for the receiver is ridiculously small, so you might try moving it closer. -- Posted by DopeSickGirl at 11:17 pm on Jan. 7, 2009 try moving it closer to the receiver thingy. -- Posted by NZ Guy at 11:19 pm on Jan. 7, 2009 when I first changed them up, i could use them from the other end of the house downstairs, so the range isnt that bad. BTW I believe its the mouse expensive keyboard and mouse combo Logitech sells.
