Update = After verifying ownership and completing troubleshooting, a DELL-Cares agent setup service.
Hi, I´m working with my WD19TB (with 240W power supply) since years now. On previous Latitudes (5411, 5401 and older) Auto Power On when connecting the dock was working fine. And it´s also working fine on my two 5421´s. After Windows shutdown the older models stayed off as I didn´t unplug the cable. But when I shut down Windows (10 and 11) on the 5421´s it completely turns off the laptop (lit Logitech keyboard goes black, so do the 2x24" Dell TFTs). After some hours, I return to the room and everything is still dark/off. But on next morning or some hours after my first check, keyboard and TFTs are lit and Windows is asking me to logon. Why did the connected and shut down 5421 automatically power on? It happens on two 5421´s for me on the WD19TB and never happened on previous models. Is there any BIOS setting which causes the laptops to boot up? Are WD19TB and Latitude 5421 incompatible? PS: I upgraded to latest BIOS/drivers/firmwares with Dell Command|Update and WD19TB firmware update tool.
Latitude 5421, WD19TB, turned off, next morning turned on?
