I had this same problem (frozen BIOS v1.15.0 update) today with an OptiPlex 5000 SFF. It was frozen in this state overnight. I left the power connected, but pulled all the other connections off the back of the machine. In my case this was 1 x Ethernet plus 2 x USBs plus 1 x DisplayPort cable. Then I plugged the single DisplayPort cable back in to see if anything was happening. The BIOS update began to run and eventually finished and booted to the Windows 11 desktop. Then I plugged the 3 remaining unplugged cables back in. It seems to be operating OK with the BIOS v1.15.0 update now thankfully completed. Weird! Neil Howard Answer from nhowardtx1 on dell.com

r/Dell on Reddit: Updating firmware stuck at 0
May 16, 2024 -
This is the third time this happens to me with a brand new, expensive Dell laptop. It seriously affects my workday. At some point during the night, the laptop decides to update its firmware, and gets itself stuck at zero, until the morning when I arrive at the office. Now, I have no way of starting the computer, as it wont power down. Its fans are going loud and there is no progress. Please, can anyone assist with this? What do I do?

Unplug all of your USBs if any plugged in. There's a issue with certain usb devices halting bios upgrades.

Hold the power button down for 10-30 seconds, until it powers down. it should be fine as it hasn't started the update process yet. In the worst case, Dells have a good BIOS recovery function.

are you able to power down and observer the same stuck issue when power up again? this looks worrisome. I would power down, disconnect power cord, press power button to drain power, replace cmos battery and clear cmos settings if possible. you see this screen would occur if you had run a bios update before. It then restarts and try to flash but fails. a failed flash can brick motherboard. I would try to abort the flash process. do not let it start on its own. for whatever reason this pc is not good for bios flash.

Hello, I have two latitude 3520 with the same problem , No reaction with Button Power (10s, 30s, and 60s) without adaptor, i contact the support They purpose me to put CTRL+ECHAP and connect Ac adaptor, same problem I resolve the problem with : - disassembly the bottom case - disconnect battery - connect battery - reboot latitude 3520 - message 'dell bios firmware failed the bios was corrupted, restore with backup bios' - system boot ok - i check Dell command update tools (no further update). Perhaps the dell support retire this corrupted bios on the website.

Please try performing a Hard Reset: 1. Disconnect any external devices including the AC adapter (and battery if possible) 2. Hold the power button down for 20~30 seconds 3. Bypass any power strips, surge protectors or battery backups 4. Verify the wall outlet is functional 5. Plug only the AC adapter/battery back into the laptop 6. Attempt to power on the system and finish the update. If that does not solved the issue, proceed to the next step. 1. Remove the AC adaptor and wait for the battery to drain completely (it can take minutes or hours depending on the battery level). 2. After the battery drained completely, connect the AC adapter back and press the Power button for 25 to 40 seconds until the battery charging LED blinks twice and then the release power button. 3. Once that is done, check if the update was complete and you have the new BIOS installed.

January 16, 2020 - The firmware updates stopped at "Updating your firmware, Do not power down your system ….. Flash Progress 100%" I called support and they had me remove the battery to get the machine to shutdown and restart. Today I noticed another Firmware update was available so I started it and got the same result. Stuck at 100% again.

Let it keep running. There have been instances on the forum where it took hours and then successfully completed. If you grow impatient and restart the system it may brick the MB.

According to support suggestions, I followed the procedure listed specific to my case (BIOS 1.10.2), and this solved the problem. .

February 4, 2021 - So, you rebooted after win update and this is where you are. Alas, your system hasn't posted. There is nothing you can do here other than shut it down imo. It will sit at this screen indefinitely. Any warranty? Maybe give Dell a shout and see what they have to say.

Thanks for the advice I never thought about it that way. I assumed that if the update is available on the official program from dell, it should always be installed.

Hi @wlod welcome to this free user to user Alienware laptop discussion forum. This is not Dell Support. Guess that BIOS update is being installed over the internet. It will now be permanently stuck, and only option is to briefly press power-on button for system to correctly slowly shut down. If power-on button held down, it will force unwanted rapid shut down. But system might only accept forced shut down. Only if BIOS update essential to get new user feature, open local admin account and download file onto your Alienware m15 R3. To ensure the integrity of your download, please verify the checksum value. Of all the Dell updates, the BIOS update must be undertaken as described within its Installation instructions.

r/pchelp on Reddit: Dell PC stuck on “Updating your firmware” — never moves past 0%
October 30, 2025 -
Hey guys, I recently bought a local Dell PC for casual web browsing and a bit of office work — nothing heavy. But since the day I bought it, every time I try to update Windows or restart after an update, it always shows:
“Updating your firmware” Dell logo → Flash progress: 0%
And it just stays stuck there for hours. Even if I leave it overnight, it doesn’t move. The only way to get it back is by turning off the plug and restarting manually. Sometimes it works, sometimes the same screen appears again.

I'm assuming it is pulling the firmware (BIOS) update from Windows update. Just enter the service tag into dell's website and download and manually install the BIOS update.

Unplug the power and let the battery drain to force shutdown - it takes around 2 hours for a fully charged battery to drop below 50% for it to shut down. Once shut down, plug the power back in and let it charge for about 10-20mins for the battery to reach over 50% then boot the machine back up. It will then initiate the BIOS recovery. If you can't wait for 2 hours, you'll have to unscrew the back plate to disconnect the battery.
