Updating BIOS on laptop with broken display
Hello everyone,
I'm new to the community and am facing a problem. Please forgive me if I fail to describe my problem correctly.
I am using Dell G3 3590 i7 9750H with 1660ti Max Q. My laptop display is broken (Dell replacement is on the way but will take weeks due to COVID-19). I am currently using an Acer Gn246-hl monitor via HDMI (wired to nvidia gpu). I do not have access to BIOS or POST on external monitor and have tried all possible ways to get it.
The problem I am facing is that I have an urgent BIOS update and it installs correctly on windows. But as I do the compulsory restart for it to update firmware on BIOS, the monitor is blank (no access to BIOS) and I hear my laptop go on and off in an infinite loop(I have waited for hours). Whereas I was expecting the BIOS firmware update to happen in the background. So to get rid of the loop, I hold my power button to restart and I'm back to square one with an urgent BIOS update on my support assist.
Help would be greatly appreciated. Thanks.

When the laptop is booting up quickly tap F12 to get the laptop to pause at the one-time boot menu.
Then Fn+F8 to get the display on external monitor.
See if that works.

Hey, I tried this earlier and it didn't work. I tried a bunch of other methods too. But I'll try it again and keep you posted.

I would ignore that BIOS update until you get the new screen installed. if you have to uninstall Dell update assistant. You should never try to install a BIOS without your notebook is 100% up and running. Anyone of them can Brick your notebook. If you want got to your support page and download the BIOS have it ready on a USB Thumb Drive then boot to your BIOS and run the file from within the BIOS, if no BIOS Flash tool is there them try it from F12 Boot some computer have it there.
Really you should wait until you have a new screen and everything is running right. and then if you won't benefit from the BIOs just ignore it. Every Bios update is taking a chance of bricking your notebook.
