BIOS (1.36) Broke My USB Support In The BIOS & Shutdown Function
Dell Inspiron 15 - (5578) / Windows 10 Home 64Bit
Updated the BIOS from 1.27 to 1.36 (17 Jan. 2022)
USB dongle is recognized in all ports, in File Explorer.
1. I cannot shut down the laptop from the menu. When I do, it automatically restarts right after showing "Shutting Down".
(a) CHOOSE OR CUSTOMIZE A POWER PLAN
I set the power button to shut down the laptop in "Dell" and "Balanced".
(b) Network Adapters
- Disabled it (which worked for some people, but not me).
(c) I tried #6 here, his, still not shutting down.

(d) Pressing and holding the power button works with Windows still open, which is NOT proper for shutting down the system.
2. BIOS not recognizing USB drive, after the BIOS upgrade to 1.36. Now, am stock since I cannot downgrade to the 1.27 I had. I need to boot a utility from a USB dongle, but I can't.
Please any help needed since I am stuck.

Thanks for the information. I was too anxious and posted it in the wrong forum.
I'll just leave it here since I have been on the TenForums on the same case.

I noticed that your post did not gain any traction for assistance. Maybe because your system is an Inspiron but you posted it in Precision mobile workstation. You may want to request Mods to move it so Inspiron users and experts could better assist you. At the meantime, I have some thoughts that may assist you in the process and maybe it can help with resolving the issue.
First and foremost, ensure that you have all your data backup when working on the system. If you suspect that the BIOS broke your hardware (USB ports) and contributed to the inability to shutdown in Windows, a CMOS reset can be performed to bring all hardware operation back to factory default settings. You will need to take note of your current settings prior to the reset so that you can make adjustment to match with current hardware settings.
The BIOS version 1.36 has been posted for almost a year so it may not having any issue with it, else it would be removed already. You can download to your machine and run it again, although I would always refrain from flashing BIOS unnecessary.
Your current BIOS may not allow you to downgrade to version 1.4.0 or earlier but there are many other versions are available in between if you are consider a downgrade path, I do not see any advantage by doing so. You can always download them to your desktop and running it within Windows. Many systems have the option to allow BIOS downgrade in BIOS settings. I do not have this model so I can't tell you for certain.
If both of the CMOS reset and BIOS reflash can't resolve your current issue, considering it a software issue and perform a clean install of Windows (not restore).
