Hi guys!
I’m getting black screen during startup (caps lock doesn’t work) on my hp spectre ( https://www.amazon.in/dp/B077BHT61N/ )
Previously I was getting it when thunderbolt plugged in. I tried system update, Now I’m getting it even with/without charging plugged in. Fallback initramfs is also behaving randomly now.
Any ideas how to debug it? Didn’t find anything in boot.log.

Just me but whenever I start experiencing random weirdness like that I test a different kernel. It's always good to have more than one installed regardless.

Just tried that, out of four reboots twice it went to black screen and twice it booted just fine.
I will try to figure that out, need to do it without messing up my boot

It's pretty simple. install an alternate kernel and headers like this:
sudo pacman -S linux-lts linux-lts-headers
Then you swap kernels after a reboot via the grub boot menu.
It's really not that hard.

Thank you @tbg .
lts kernel just worked fine and I am not having any issues.
Yes its pretty simple. Previously I was trying to look for 5.8 kernel, didn't go for lts.
I'm not sure if this in scope of this forum or not - how can we figure whats wrong with the newer kernel?

Ya, that's a little more complicated. If you want to go down that rabbit hole research "how to bisect a kernel".
So glad that sorta fixed things for you. Test the newest kernels out in a few weeks maybe things will have improved.
Glad to be of assistance.
Welcome to the forum BTW.
