Does any of you know where the BIOS battery is on my laptop
It differs from model to model. Usually it is covered with this black plastic film.
Unfortunately, no
Have you checked under the fans yet?
Since I can't see anything, it can only be under there
Well, nowhere in the picture.
Maybe behind a cover, maybe on the other side, maybe there isn't.
There's definitely one. Lol.
No. Many modern laptops use a capacitor in conjunction with the Li-ion battery.
You can't say it like that. Possibly on the other side, or it is soldered and not easily recognizable for you.
