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. Now I have about 5 different production dates to test. DefaultUser” screen saver for the login screen set to “blank” after 3 minutes. Fast-forward a few months to April I never tested system sleep, but I’m sure they would also bring a system out of sleep. The best part in all this is that the mouse also affects non-Dell systems. Still no resolution, so I install the Lenovo mice and move on.

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. The best part in all this is that the mouse also affects non-Dell systems. Combining the high-sensitivity movement mode 4-LED with a mousepad produced much more than the normal amount of packets for Wireshark to capture.

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 sleep. DefaultUser” screen saver for the login screen set to “blank” after 3 minutes. Sometimes they are enough to stop sleep, or screen saver.
Still no resolution, so I install omczul Lenovo mice and move on. Fast-forward a few months to April I contacted Dell first-level support through Chat, but this didn’t go very far.
And some would come out of screen saver or sleep back to the login screen. 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. Fast-forward now to Septemberand this issue is still gnawing at me. 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.
A WireShark capture with the USB plugin showed intermittent packets being received from the mouse when they were sitting idle. We imaged these with a custom built Windows 7 image. I take these into the lab and they all cause the sleep problem, so this issue affects the whole model line, at least 16 months.
In our training labs all the mice are on mousepads, but I’ve been testing on an anti-static mat when on my bench. The original Lenovo mice never had this problem. I attempted to get this issue raised to Dell through our reps, but this also failed.
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. Now I have about 5 different production mocaul to test.
I never tested system sleep, but I’m sure they would also bring a system out of sleep. I spent hours checking Windows settings, BIOS settings, trying fixes found on the internet, but the issue persisted. Putting the mouse on a rough nylon mousepad really brings out the issue.
Since I never found a resolution, I simply pulled all the Dell mice and replaced them with the old Lenovo mice, and the panels slept fine.

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. I then let the moczzul go idle and watched them for minutes. As of late September I have finally reached someone at Dell above level 1, and am in the process of diagnosing the mofzul.
It also caused the same issue on the Lenovo system. Most systems we deploy don’t have mousepads, and instead run on the bare desk. These systems are set to “high performance”, no system sleep, panels set to sleep after 45 minutes, and the “.

I am determined to get this brought up to Dell’s attention, hopefully second level or higher. This test proved my theory! 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. One de,l the last tests I did was also the most telling.
