Latitude 7420 BIOS update to 1.9.6 cause system boot delay

Just checking to see if anyone has similar issue.

We've recently bought 5 new latitude 7420 laptop. running 1 unit through command update to get all the latest drivers & patches I noticed it takes almost 2 min to get Dell logo to show on the power up screen.

Wasn't aware of the issue at the time, until  noticed the same issue when I go through setting up the second unit.

Both units are running BIOS version 1.9.6.

Then I fired up the 3rd unit just to confirm, only updating BIOS this time and nothing else, same issues happened.

Dropped BIOS version down to 1.9.3 and boot delay issue disappears.

Has anyone had similar issue?

BIOS 1.12.2 appears to be fixing the issue for some. If you have not installed it, do so and retest. BIOS 1.13.0 addressed a different issue.

I was having the same issue. The laptops came with version 1.9.6 and the boot delay was terrible. Dropped to 1.9.3 and issue is gone.

If still under warranty, click the "Get help now" icon on the right to start a live chat session. Currently only available in the USA.

I can give you 10 serials. I have the useless Pro Support on 10 of these machines.

And before you ask, it has the Dell image and Windows 10 Pro that came with it.

If it is not BIOS issues, it is stuttering that people complain about. If not stuttering its audio issues.

These machines are not performing.

Glad I came across this. Nearly 45 seconds to POST is not good. Would have been tickets galore. Dropped to 1.9.3 and no change. Keyboard lights up, fan spins, 45 seconds later the machine will POST. Painful to wait for these to boot.

Backed off my Latitude 7520 to BIOS 1.9.3 and post is fine but I did notice the big delay going to 1.9.6.  Worse yet, I started having memory issues with 1.9.6 even though that is the only listed "fix";

"- BIOS V1.9.6 addresses potential memory corruption issues by making adjustments to memory frequency to improve overall system stability"

I had multiple issues of memory corruption after upgrading to 1.9.6 which I have never seen before. I have backed off to 1.9.3 which was working fine for me before so we shall see if the memory issue is also resolved.  Sounds like Dell needs to pull 1.9.6 until they get it fixed.

I too have noticed this...is what brought me to this thread. I noticed it first on my own PC. We're just now imaging and rolling out a couple hundred new units that have already been fully updated. Hope Dell pushes a fix quick to Command Update. I'd hate to have to go roll back 300 PC's!

Also downgraded to 1.9.3 - at least that worked...

We have the same problem with 7320. All computers with 1.9.6 takes about a minute longer to boot.

Not only I'm experiencing the mentioned boot delay. My system also runs in memory-related BSODs since upgrade to 1.9.6, although that should have been fixed but never was an issue before. Not good, Dell!
