I have a Dell Inspirion laptop with bluetooth. I bought a Microsoft Keyboard Elite for Bluetooth & Intlimouse for Bluetooth 3 months ago. It worked great out of the box; however about a month later after leaving computer for about 30 minutes, upon return, I could not get either to wake up computer. Checked to see bluetooth radio was on, tried reconnecting in Settings and it said it could not locate device. I uninstalled/reinstalled keyboard and that didn't worked. Turned it off, next morning worked fine. A week later, same thing. I checked on updated driver for bluetooth from Dell, checked Microsoft for new keyboard/mouse driver. Restarted computer, no luck. Turned off, next morning fine. This has happened about 4 times in 3 mos then last 2 days first the mouse will quit while computer is awake - go to use it, nothing -- walk away for 15 minutes and come back and keyboard stops. It seems the only "fix" is turning off and on (not restarting) computer to get it to work again. Any help with this aggravating problem is appreciated. I'm about ready to go back wired and ditch the bluetooth.
