Update September 27, 2021 = A DELL-Cares agent setup service.
I got this issue since last time I upgraded to BIOS 1.0.7. That time the power was interrupted when upgrading bios to 1.0.7. I couldn't startup my PC after that so I searched on youtube and solved the problem by disconnect the power and release the remain power by press the little black button at the rear of PC. Now the problem is every time when I startup PC the power only last half second and off, then leave it for 5-6 second it will startup by itself like normal.  I tried to upgrade BIOS to 1.0.8 , I run the upgrade EXE from windows the PC will then restart, and then you will see the  BIOS upgrade screen only flash half second the power goes off, then after few seconds the power on for another half second and off, then on again into windows as normal. The bios is still staying on 1.0.7 Anyone here has the same or similar issue? How to resolve them this is super annoying me. Thanks.
