Go to Solution7420 : 1 minute cold boot, after bios v1.96
My new (unused) 7420. Turned it on, let the Dell command update do its thing. That included bios 1.96 and numerous Intel patches.
Now the cold boot takes 58 seconds to show the POST screen logo. It looks to be doing the thorough boot check from cold every time. The BIOS is set to minimal fast boot. Clearly a mistake somewhere causing it to do this long boot check on cold boot. How to fix?

Hello, I work at a university and we have ordered over 50 Dell 7420s. We are having the exact same issue with all the Dell 7420s that we have opened so far. We require a fix ASAP as this is unacceptable boot times for our end users.

I downgraded to BIOS 1.9.3 and it's not having the long cold boot anymore.

Both machine requested to update the BIOS after the initial setup. One ... (1) 1-2 minute delay in getting to Boot Manager

Ah, just found this thread, I just posted another one. I have the exact same issue. I tried switching the boot priority to the SSD boot drive, it is slight faster but still takes at least half a minute to see the Dell screen.

We seem to have made some progress with Dell. They have pulled bios v1.96 from the website, making v1.93 the latest available. So it seems a repair is on the horizon?

v1.9.6 is a botched update...roll back to v1.9.3.

Update October 17, 2021 = A DELL-Cares agent setup service for rossh0.
Both of these are still under investigation.
Latitude 7320/7420/7520 slow boot with the now pulled BIOS 1.9.6. The workaround is to roll back to BIOS 1.9.3.
Latitude 7320/7420/7520 may experience blue screen issue when in idle or daily operation. The workaround is to turn C-State off in the BIOS- Performance.

New bios version 1.11.3 (Nov 12th 2021), has solved the issue. Problem solved.
