I have a brand new HP Pav-510 P127c. I am using a Logitech M305 Wireless mouse. The mouse disappears several times a day. I haven't noticed any thing in specific to cause the mouse to disappear. I've uninstalled and reinstalled the mouse driver. The only way to get the mouse to reappear is to do a hard reboot. I've tried moving the wireless mouse adaptor to a different USB port - no luck. Thank you in advance.
