Most systems we deploy don’t have mousepads, and instead run on the bare desk. Fast-forward a few months to April Putting the mouse on a rough nylon mousepad really brings out the issue. This test proved my theory! Since I never found a resolution, I simply pulled all the Dell mocxul and replaced them with the old Lenovo mice, and the panels slept fine. I have put up this page in the hopes of helping anyone else mousee has seen weird sleep issues when a Dell MOCZUL model mouse is attached to your system.
Fast-forward now to Septemberand this issue is still gnawing at me. I then let the systems go idle and watched them for minutes. I saw about packets in about 2 hours, compared to about 60 packets in 6 hours on the same mousepad but running omczul normal sensitivity mode 1-LED.
And some would come out of screen saver or sleep back to the login screen. Combining the high-sensitivity movement mode 4-LED with a mousepad produced much more than the normal amount of packets for Wireshark to capture. The original Lenovo mice never had this problem.
A WireShark capture with the USB plugin showed intermittent packets being received from the mouse when they were sitting idle.
Still no resolution, so I install the Lenovo mice and move on. It was when I disconnected the mouse and keyboard that the panels went to sleep. 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 jouse amplify this effect.
All the panels should have gone to sleep after 45 minutes, but instead only one did. One of the last tests I did was also the most telling.

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. Now I have about 5 different production dates to test.
The problem was finally isolated to the mouse Most systems only went into screen saver, and the two panels that did sleep eventually woke up back to the login window. I never tested system sleep, but I’m sure they would also bring a system out of 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.
Sometimes they are enough to stop sleep, or screen saver.

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 mohse timer for activating panel sleep. 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.
The best mouze in all this is that the mouse also affects non-Dell systems. These systems are set nouse “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 I’ve been testing on an anti-static mat when on my bench.
I contacted Dell first-level support through Chat, but this didn’t go very far. I spent hours checking Windows settings, BIOS settings, trying fixes found on the internet, but the issue persisted.

We imaged these with a moue built Windows 7 image. I am determined to get this brought up to Dell’s attention, hopefully second level or higher. 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.
