Question about Microsoft Wireless Laser Desktop 4000 Keyboard/Mouse
I'm on my second 4000 and I'm suddenly having the same issue as the first. I was typing and using the mouse and suddenly the lights on the receiver started flashing, then stopped with two lit. Nothing worked, so I rebooted and now the receiver doesn't appear to be working at all...no lights, etc. I've tried every USB slot on my dock and laptop, and rebooted a number of times to no avail. Is this a known issue, and is there any way to get it working again?
Make sure that you have no other wireless devices nearby. I had a similar issue and it was because of a cordless phone I was using. Switched the phone to 5.8GHz and problem with sync was solved.

They need to be re-synced. Sometimes the wireless signal from the keyboard/mouse is broken and the receiver cannot find it again. A quick re-sync always fixed the problem for me.

Re-syncing is not the issue. The receiver flat out doesn't work - no lights, etc. Pressing the sync button doesn't make anything happen...
same thing happened to me
