lumber (Dell OptiPlex 7080 Micro)
Summary
This was a former Crestron UC-ENGINE-D-T. I put the Dell UEFI firmware back on it, reset the Dell Logo, and transfered a regular Win 10 install to it (Crestron uses Win 10 IoT).
Notes
- Has the extra HDMI output module
- Came with a 130W power supply module (overkill)

Log
Another UC-Engine, Minor nightmare restoring Dell configuration
After my good experience with wing, I occasionally look for more Crestron UC-ENGINE machines.
I wanted to upgrade a Dell 9020 USFF desktop machine (i5-4590s, 65W 4c4t), and I found this unit.
It was still mounted to the metal wall plate, and in the original box. I could just make out the "UC-ENGINE-D-T", and that suggested a OptiPlex 7080 Micro i5-10500T (35W 6c12t) with 8GB/256GB. Price was good, and nobody bid so I made out well.
Other things in the box:
- Crestron HD-CONV-USB-200 (see details in wing's first log entry
- Crestron 20' HDMI cable
- Crestron 6' HDMI cable
- Crestron 6' Active DisplayPort to HDMI Cable
- Cable Matters USB 2.0 100M NIC
- Crestron HDMI pass-through EDID emulator
- 16.8W ITE PoE 802.3af injector
- Crestron TSW-UMB (in-wall mounting bracket for touch-screen)
First POST was very slow, and there was some yellow LED flashing on the power button. The machine needed a new coin cell battery, but after that it started POSTing normally.
Getting Windows running normally was a bit of a mess. By default it logs in to a Teams account, and launches that full screen. I grabbed the most recent Dell BIOS, and overwrote that.
Between Windows, and Dell's auto-recovery I failed repeatedly to get into safe mode. I tried the 5 Win key button presses to switch users, and logged in to the Admin account, but whatever was running on the Teams account still managed to blank the screen, and eventually force a reboot.
Every other boot it would try to load the Crestron UEFI, fail because it was a version downgrade, then reboot.
Eventually I booted a Win 10 installer image, got to the command prompt, and used bcdedit to enable safe mode. I didn't realize I had succeeded because there's no indication for safe mode until you get to the desktop. Even once there, the Teams account was still doing its thing, and rebooting the machine after a bit. I deleted the account somehow (can't remember if it was from the installer, or just logged into the Admin account), and disabled the auto-login in regedit.
With uninterrupted admin access, and switched back to non-safe mode I was able to run the firmware update from Windows this time, and pass the /DellLogo flag to restore the UEFI boot logo.
Google's AI lied, saying all 7080's come with a Win 10 Pro license. I didn't have much to lose (was going to clone the old drive, and try hardware change activation). I thought a fresh install would be nice so I tried that, but it wouldn't activate.
This machine came with a 8GB DDR4-3200 kit (2x4GB) even though the i5-10500T only does DDR4-2666.
I traded the ram for wing's 16GB DDR4-2666 kit for now. Memtest86+ passed.
I got a USB Logitech audio adapter to give me a rear speaker output. I might stick a fresh 1TB 2.5" drive in for the backup device, and then I can preserve the old one for a bit. Maybe grab a USB hub to reduce the cable clutter around back.
