I had this problem at work a week ago or so, at least with Fujitsu PCs. For them, the main cause isn't an empty CMOS battery, but rather that Fujitsu generally had too little BIOS cache, since there is nothing about it in the UEFI standard. The update basically overfilled that cache, rendering the BIOS completely unusable. The POST doesn't even go through fully.
The PC are sort of bricked, you gotta put the mainboard into recovery mode, put the ROM file on a freeBSD formatted stick and wait until you see instructions on the screen. Follow them, restart the PC. I recommend setting the BIOS to the optimized default settings, as not doing that might make the boot of Windows pretty slow in some cases. I did hear that it can delete the keys from the TPM, but I haven't seen that with my PCs at work.

Wow what a super cool website without cookie opt-out.
Not only that, if you try to click any of the links, like the partner list or privacy statements, it takes you to another page with the same pop-up over it... So you have to accept the shit to read their disclosures... What a shitty website, unless the purpose was to keep the information a secret, then it works great because I sure as shit didn't read it.

Is this for real?
Yes, multiple of our Windows laptops today couldn't boot and displayed a BitLocker error message and all affected laptops somehow had an empty BIOS battery...
Can it at least be fixed with a new battery? Or does that get drained quickly too?
AFAIK a new battery + entering the Bitlocker recovery key fixed the problems.
Usually these batteries hold for years. I have a 15+ year old laptop where I had to replace the battery after ~10 years.
However the affected laptops are now a few years old, aren't designed properly (I heard weird stuff happening like adding additional RAM somehow causes the display to fail) and somehow just have a CR2016 battery installed, not a bigger CR2032. And yes these are buisness-laptops designed for companies -.-

What all am I looking at here? Or is this all meme?
It's a meme about how draining the cmos battery bricked some PC's, I think. It's formatted like the Wikipedia sidebar summary for articles on wartime battles.
