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. 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. It was when I disconnected the mouse and keyboard that the panels went to sleep. Putting the mouse on a rough nylon mousepad really brings out the issue.
Sometimes they are enough to stop sleep, or screen saver. We imaged these with a custom built Windows 7 image.

Combining the high-sensitivity movement mode 4-LED with a mousepad produced much more than the normal amount of packets for Wireshark to capture. Fast-forward now to Del,and this issue is still gnawing at me. 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.
This test proved my theory! 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. Most moczl we deploy don’t have mousepads, and instead run on the bare desk. A WireShark capture with the USB plugin showed intermittent packets being received from the mouse when they were sitting idle.
It also caused the same issue on the Lenovo system. Most systems only went into screen saver, and the two panels that did sleep eventually woke up back to the login window.
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. And some would come out of screen saver or sleep back to the login screen.

The original Lenovo mice never had this problem. 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 part in all this is that the mouse also affects non-Dell systems. These systems are set to “high performance”, no system sleep, panels set to sleep after 45 minutes, and the “. 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 xell.
In our training labs all the mice are on mousepads, but I’ve been testing on an anti-static mat when on my bench. After the systems had sat idle for a few hours I noticed that only delll half the panels were sleeping, where instead all should be. One of the last tests I did was also the most telling. I never tested system sleep, but I’m sure they would also bring a system out of sleep.
As of late September I have finally reached someone at Dell above level 1, and am in the process of diagnosing the issue.
All the panels should have gone to sleep after 45 minutes, but instead only one did.
Dell MOCZUL mouse issue
Still no resolution, so I install the Lenovo mice and move on. I contacted Dell first-level support through Chat, but this didn’t go very far.
It is delk fascinating watching a room of 20 systems where the panels are randomly mouss 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.
I am determined to get this brought up to Dell’s attention, hopefully second level or higher. 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.
