The organization I work for purchased 100 Dell OptiPlex 7000 machines a couple of months ago. I have deployed about 20 of them so far and of those 20 deployed machines, at least 4 that I know of have had significant overheating events. Three of them are on Windows 11 and one on Windows 10. What I have seen is that when the user tries to awaken the machine in the morning it is unresponsive, and the side of the box is extremely hot where the CPU is mounted (also same spot as the 3 video DP plugs). After pressing the power button for a while it eventually wakes up the monitor and shows a white screen with the following text: ! SupportAssist detected a high system temperature. Ensure all cooling vents are clear of obstructions and uncovered when in use.(Previous Thermal Failure) Alert! Previous shutdown due to thermal event. [Continue] After clicking on Continue it switches to a blue screen that says: RecoveryIt looks like Windows didn't load correctlyIf you'd like to restart and try again, choose "Restart my PC" below. Otherwisd, choose "See advanced repair options"for troubleshooting tools and advanced options. If you don't know which option is right for you, contact someone youtrust to help with this.[See advanced repair options] [Restart my PC] After clicking restart the fan(s) go to maximum for 20-30 seconds and then things seem to return to normal. This is apparently related to the machine going to sleep. It had been reported by users to have happened multiple times before info got to us in IT and we realized the dangerous condition and started paying close attention. I have disabled sleep in the bios for those 4 machines, and will probably now need to do so for the other 16 deployed machines, and 80 which are yet to be deployed. I would dearly love to come up with an answer that assuages the after-hours-fire concerns of my superiors so that I didn't need to disable sleep on this many machines. Not that it's a massive amount for us to absorb, but a sleeping machine uses 1-2 watts while a resting machine uses 7-8 (as anecdotally measured by my Kill-A-Watt meter). Multiplied over 100 machines that's 600 watts overnight of waste. After the issue I ran DELL Command Update again and had it install the 1 new critical update it found. [URL] This BIOS driver doesn't seem to have any sleep or overheating. Here are the two listed fixes: - Fixed the issue where the Show Password option is not displayed under the Wireless Networks in the BIOS setup.- Fixed the issue where the system reboots repeatedly when USB bootable devices with longer product name and serial number are connected to the system. I also ran the few "Recommended" updates that I had not run before. I'm not confident though that any of them would address what seems like a critical issue. I opened an incident with DELL support but they didn't seem particularly interested in digging into this. So here I am hoping someone in the community can help me with some ideas. Thanks, Paul
