Fast-forward a few months to April Sometimes they are enough to stop sleep, or screen saver. The problem was finally isolated to the mouse I am determined to get this brought up to Dell’s attention, hopefully second level or higher.
DefaultUser” screen saver for the login screen set to “blank” after 3 minutes. I then let the systems go idle and watched them for minutes. We imaged these with a custom built Windows 7 image.
Moouse I have about 5 different production dates to test.
I have put up this page in the hopes of helping anyone else that has seen weird sleep issues when a Dell MOCZUL model mouse is attached to your system. I nouse these into the lab and they all cause the sleep problem, so this issue affects the whole model line, at least 16 months. What seems to be happening is the packets that are being sent from the mouse don’t always push the panel out of sleep mode or out of screen saver, but instead seem to reset the internal timer for activating panel sleep.
Putting the mouse on a rough nylon mousepad really brings out the issue.

And some would come out of screen saver or sleep back to the login screen. Most systems only went into screen saver, and the two panels that did sleep eventually woke up back to the login window. It is truly fascinating watching a room of 20 systems where the panels are randomly changing states, intermittently coming out of screen saver to the login window, or panels going to sleep only to wake up again, never going into screen saver or never reaching mousd.
The original Lenovo mice never had this problem. This test proved my theory! One of the last tests I did was also the most telling.

The best part in all this is that the mouse also affects non-Dell systems. So this issue is not related to drivers, BIOS revisions, or even limited to a few system models, it is definitely a mouse hardware issue.
Combining the high-sensitivity movement mode 4-LED with a mousepad produced much more than the normal amount of packets for Wireshark to capture. These systems are set to “high performance”, no system sleep, panels set to sleep after 45 minutes, and the “.

In our training labs all the mice are on mousepads, but ,oczul been testing on an anti-static mat when on my bench. All the panels should have gone to sleep after 45 minutes, but instead only one did. It may not be a safety issue, but certainly affects the systems ability to reach sleep consistently which causes higher power consumption and will reduce the life of panels that can’t reach sleep mode.
After the systems had sat idle for a few hours I noticed that only about half the panels were sleeping, where instead all should be.
I never tested system sleep, but I’m sure they would also bring a system out of sleep. I attempted to mooczul this issue raised to Dell through our reps, but this also failed. A WireShark capture with the USB plugin showed intermittent packets being received from the mouse when they were sitting idle.

Most systems we deploy don’t have mousepads, and instead run on the bare desk. It was when I disconnected the mouse and keyboard that the panels went to sleep. Fast-forward now to Septemberand this issue is still gnawing at me. As of late September I have finally reached someone at Dell above level 1, and am in the process of diagnosing the issue. I had a theory that the MOCZUL was incorrectly detecting movement, and by turning up the DPI setting button on the top of the mouse to its highest value, it would amplify this effect.
Still no resolution, so I install the Lenovo mice and move on. It also caused the same issue on the Lenovo system. I saw about packets in about 2 hours, compared to about 60 packets in 6 hours on the same mousepad but running in normal sensitivity mode 1-LED.
