Hello there, I’m currently facing this issue at the moment. Was the laptop loading to OS when you restarted it later? Or did it fail?

Hello there just to give an update.

I had contacted dell support and they had asked me to manually remove the connector from battery to mb

After this I drained the excessive charge from all the components by holding the power button of the laptop for 1.5 minutes

Then I rebooted the machine and it worked

however I would not suggest anyone to try the above steps without an official consultation with a dell certified support engineer or agent

We are facing this issue with our customers. Update have been deployed via Dell Command Update and same symptom...

Asking users to take off back of the computer and disconnect the battery is not an option at all!

We will have to wait for battery to drain completely to be able to boot again. I can't understand this lack of communication from Dell!

facing the same problem here, on a brand new Dell Latitude 3520, after downloading and installing the BIOS update using Dell Update..... I'm currently waiting for the battery to drain out, in the hope that after the boot you can gain access to the computer:

Same issue over here on our Dell 3520 laptops.  BIOS update fails and gets stuck on 0% "Saving Manifest".  Holding power button does nothing.

@cmoore96 yes that seems to resolve it, not ideal when you have hundreds/thousands of devices out with end users who you wouldn't want to be dismantling a laptop.

i remember when you could pull a battery out of a laptop and when you could change a keyboard without tearing the whole thing to 10000 pieces
