The best part in all this is that the mouse also affects non-Dell systems. Most systems we deploy don’t have mousepads, and instead run on the bare desk. The original Lenovo mice never had this problem.
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. Fast-forward now to Septemberand this issue is still gnawing at me.
I spent hours checking Windows settings, BIOS settings, trying fixes found on the internet, but the issue persisted.
Combining the high-sensitivity movement mode 4-LED with mous mousepad produced much more than the normal amount of packets for Wireshark to capture. I contacted Dell first-level support through Chat, but this didn’t go very vell.
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. And some would come out of mose saver or sleep back to the login screen.
I attempted to get this issue raised to Dell through our reps, dell this also failed. 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.
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. We imaged these with a custom built Windows 7 image.
Dell MOCZUL mouse issue
One of the last tests I did was also the most telling. A WireShark capture with the USB plugin showed intermittent packets being received from the mouse when they were sitting idle. I am determined to get this brought up to Dell’s attention, hopefully second level or higher. The problem was finally isolated to the mouse These systems are set to “high performance”, no system sleep, panels set to sleep after 45 minutes, and the “. Still no resolution, so I install the Lenovo mice and move on.
In our training labs all the mice are on mousepads, but I’ve been testing on an anti-static mat when on my bench.
Dell Silver USB Laser Optical Mouse MOCZUL
Fast-forward a few months to April Now I have about 5 different production dates to test. 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. 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 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. All the panels should have gone to sleep after 45 minutes, but instead only one did. 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.
Putting the mouse on a rough nylon mousepad really brings out the issue. This test proved my theory! As of late September I have finally reached someone at Dell above level 1, and am in the process of diagnosing the issue.
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 mooczul can’t reach sleep mode. It was when I disconnected the mouse and keyboard that the panels went to sleep.
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. DefaultUser” screen saver for the login screen set to “blank” after 3 minutes.
