I have two identical Dell E6420 laptops that I have upgraded to Windows 10.  After the upgrade I put a fresh install of Windows 10 Pro and everything worked great.  Until I wen through and ran all of the updates.  

Made it fine through the 1607 update.  But I believe it is the last big developer update that took them out.

 

Before the final install I made sure to update the Bios to the A24 to make sure that was not the issue.

 

Any ideas on were to look next?

 

Thanks for the help!

Were I you I would definitely touch base with Dell support about this.  I'm suspecting that they didn't patch something that needed patching and that you'll be far from the only person with this issue.

 

Instant bricking on identical machines suggests something very specific to them.

When you say bricked, you mean no power on, no post, nothing?

Powers up and goes through the Dell start up screen.  Screen stays black after that.  Power is definitely on though.

If you follow this procedure do you get the Advanced Boot Options Screen?

 

  • Hold the Power Button for 5 seconds or until the computer completely shuts off.
  • Press the Power Button to turn the computer on.
  • As soon as you see the rotating loading circle, press and hold the Power Button until the computer shuts off.
  • Repeat this process 2 or 3 times until you see the Preparing Automatic Repair screen.
  • Let the computer boot to the Automatic Repair screen.
  • Click Advanced Options, and then select Troubleshoot.

Yeah, I have tried running it through the troubleshoot options. Keeps coming up unable to fix.

 

Even though these run very well on Windows 10.  I may just have to put them back to Win 7 Pro.

Neither are the 100's of others I have updated.  I do not believe at this point that they test anything for the upgrades anymore.

I have decided to back these up to win 7 pro.  There is definitely something that I have not figured out yet.

 

Thanks for the help people.  Let me know if you think of anything else. :)
