Precision 7560 & 7760 Owners' Thread

Well, weirdest darn thing and the only thing I absolutely don't like about the Dell 7760: mine turns itself on by itself with no reason at 8:24:11 am EDT on the 18th of every month.

This is the third month in a row that mine did this. It did it on November 18th and December 18th at the exact same time, so I decided to be sure to be in front of it with it off this morning at 8:24:11 to be sure it wouldn't do it again, and sure enough, it turned itself on, by itself, again for a 3rd time from a shut down state. I don't like that at all.

(It was connected to AC power to a UPS, no power fluctuation, disconnected from ethernet today to be sure in case it was some weird wake on lan thing, no dock connected, bios flashed with update since it happened a month ago, auto-on time set to disabled in bios, wake on lan disabled in bios, previously shut down with start menu -> power -> shut down)

 

Hi. Could you check for me the exact model of this AUO display, whenever you have a minute or two? I hope there is an analog for the 17.3 size. Thx.

 

I would open "Task Scheduler" and see if there's any monthly maintenance job defined at that specific time. Also, you can use Event Viewer to see what kind of events were triggered around that time and you'll probably get an idea of what caused the shutdown.

 

It's not a shutdown, though, it's a startup; Windows shouldn't be running when it triggers.

 

I turned this off on my setup and the power button on the dock does work. Now instead of automatically turning on, I have to press the power button. A few times I got it where the second light on the dual USB did not light up fast enough and I got the error message.

You can still use dock power button or laptop power button but connecting USB Type-C cables will not start the laptop automatically. Still the best result is always using the laptop bower button.
Sometimes using dock power button external displays remain black during startup so that's why I am not using it any more.

Have you installed Thunderbolt Control Center? From here you can see using "three lines" - About

Hi, what do you think about the processor, Xeon or i9 ?

For use the 3ds max vray, revit, photoshop, unreal and other graphic software.

 

The only difference is ECC memory support. If you want to use ECC memory (or think you might in the future), get the Xeon; otherwise, there is no reason to consider it.

 

I manually shut the computer down last night with the Windows 10 Start Menu, Power, "Shut Down" and watched the blue screen saying "Shutting Down". Since it happened twice before on the 18th of the month at the same time, I was very careful to watch it last night to make sure I didn't hit reboot or sleep, and am 100% sure I hit Shut Down.
The Dell Bios system logs also shows

01/18/2022 01:12:28 Power Off - ACPI power management
(from when I shut down the Dell 7760 from windows start menu last night, and then next line is the phantom power on)
01/18/2022 08:24:11 Power On - Not applicable
(the phantom power on this morning when I didn't touch anything and it just turned itself on again.)

Windows "Turn on Fast Startup" is set to Off under windows control panel power options.

Big question: can a windows scheduled task wake up a Precision 7760 when it has been Shut Down with the Start Menu->Power->Shut Down?

Or is the Dell Bios the only thing that can power on the system at a specific time when windows has been "shut down" to power it off?

 

could it be something on the network or a usb device powering it on? being the same time seems like a setting in the bios telling it to turn on at that time but that setting is not in the bios (at least for mine). Hard to troubleshoot when it is once a month. I leave mine on 24/7 except when traveling to and from the office so usually on at 0824.
