I just did the 1.5 update last week but do not show the log file you reference.  Do you have any other log files  I could check?

Did you do any during or after your last successful Bios update which might be involved in your current situation?

I found this site but I do not know if it might be relevant to your situation.

Can you try create request to Dell support assist? I have always problem to create one.

Just download SupportAssist software from https://downloads.dell.com/serviceability/catalog/SupportAssistInstaller.exe

And there is a option GET SUPPORT

Did you ever resolve this problem?  I'm having the same issue.

If you have enabled the security in your BIOS, you have two options:

1 - disable the password and install the update.

2 - install it manually using the password (more technical):
 2.1 - Download the executable file.
 2.2 - Open Command Line and navigate until the downloaded instalation file.
 2.3 - Execute the following command in CMD (usually the parameters are the same but if you want to make sure, run /? instead of /s/f/p/l):
        FILENAME.exe /s /f /p="BIOS_PASSWORD"  /l="C:\log.txt"

After do the above, check the result in the log location C:\log.txt

Hi, 

Thank you for your reply. The issue remains the same. The log states no problems and a successful patching, but when rebooting I'm still stuck on the old version.  I have no BIOS password active.

Hi, 

No change. I have no BIOS password. When running the command i get the same result:

Hi, 

Thank you for your reply. I'm not having any BIOS password. When running the command the log looks promising, but no success:

After rebooting I'm still on the old version :-(

When you download the update and double click it to start, the system restarts and show the update progress.  You can watch while that is happening and see exactly what is being updated.  The initial message you get shows what will be updated.

Have you been able to notice how far the update process got and did it seem to terminate early and any error messages?

If it proceeds normally, it should reboot and leave you at the lock screen.  If you have done this and msinfo32.exe still shows the old bios then all I might think is you may need to install an earlier version due to some of the Intel Microcode updates, but I have no indication this would actually be necessary.

Is your system one of the new ones with the 8th generation processors?

@hi, The laptop shows no bios update indicator/bar after rebooting. It reboots directly into windows. I think this might be the reason. I managed to downgrade the bios from 1.3.1 to 1.2.1. a while back hoping to be more successful starting at another version. When downgrading I got the update indicator. I have the following processor: Intel(R) Core(TM) i7-7Y75 CPU @ 1.30GHz, 1601 Mhz, 2 Core(s), 4 Logical Processor(s)

You have the same system I have..  Did you verify the download integrity?  I don't normally do this but your situation does not appear to be normal.  I did not see the 1.2.1 version on the download site, just the 2.2.0 which I never updated to but bypassed it for the 2.2.1 version.

Just in case, are you showing the TPM v 2.0 firmware installed?  I am not suggesting you do anything yet.
