T7960 won't shutdown

System only reboots when screen click or power button pushed - won't shut off.

BIOS settings: (unchanged)

AC Recovery - Power OFF

Auto On Time - Disabled

Deep Sleep Control - S4 & S5

USB Wake Support - OFF

Wake on LAN - Disabled

Block Sleep - OFF

Intel speed shift technology - On

USB power share - OFF

Active state power management - Auto

Screen click shutdown displays "Going into Standby Mode" (??) before immediate reboot

Power button LED fades down twice then immediate full on before reboot

Holding the power button in for 20+ seconds causes reboot with BIOS setup warning display

I haven't tried unplugging power cord because I don't know when to do it

    In Power Profile, turn OFF Fast-Startup.

    With a bootable SSD, you don't need it anyway.

    If still a problem, look in Reliability History Report and find out what is happening.

    Yeah, you need to be able to do a proper/clean Shut-Down.

    Hello,

    just to make sure, has windows update by chance applied the february updates just before you had this issue ?

    This said, try to open a command prompt and do a shutdown using this command

    shutdown /s /t 0

    SUCCESS!!

    Thanks to all and Dell Support

    Upgraded BIOS from 2.16.1 to 2.17.0

    Changed BIOS to Factory Settings

    WIN 11 - disabled Fast Startup and Allow Wake Timers

    Screen click shutdown worked!
