I never tested system sleep, but I’m sure they would also bring a system out of sleep. In our training labs all the mice are on mousepads, but I’ve been testing on an anti-static mat when on my bench.
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.
Dell MOCZUL mouse issue
I have put up deol 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. These systems are set to “high performance”, no system sleep, panels set to sleep after 45 minutes, and the “.
Most systems we deploy don’t have mousepads, and instead run on the bare desk.
As of late September I have finally reached someone at Dell above level 1, and am in the process of diagnosing the issue. 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 of the last tests I did was also the most telling.
And some would come out of screen saver or mocul back to the login screen. Still no resolution, so I install the Lenovo mice and move on. The best part in all this is that the mouse also affects non-Dell systems.
Sometimes they are enough to stop sleep, or screen saver. Fast-forward now to Septemberand this issue is still gnawing at me. A WireShark capture with the USB plugin showed intermittent packets being received from the mouse when they were sitting idle.
Putting the mouse on a rough moczjl mousepad really brings out the issue.
This test proved my theory! I contacted Dell first-level support through Chat, but this didn’t go very far.
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 de,l panel sleep.
Now I have about 5 different production dates to test.

All the panels should have gone to sleep after 45 minutes, but instead only one did. The original Lenovo mice never had this problem. 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. I then let the systems go idle and watched them for minutes.
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. 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. The problem was finally isolated to the mouse Fast-forward a few months to April I spent hours checking Windows settings, BIOS settings, trying fixes found on the internet, but the issue persisted.
We imaged these with a custom built Windows 7 image. Depl the high-sensitivity movement mode 4-LED with a mousepad produced much more than the normal amount moczuul packets for Wireshark to capture.
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.
Most rell only went into screen saver, and the two panels that did sleep eventually woke up mlczul to the login window.
I attempted to get this issue raised to Dell through our reps, but this also failed. DefaultUser” screen saver for the login screen set to “blank” after 3 minutes.
