Nowhere in my laptop i can find the BIOS/CMOS battery. I opened all
panels and looked under removable parts including the keyboard, but
nowhere i could find the small battery.
So i start to believe that this laptop does not have a battery to
maintain the BIOS settings and have the internal clock going. Is it
possible that modern laptops do without a battery (and use for
instance a high capacity capacitor to sypply power to the BIOSmemory
Has anybody any ideas?

You are correct to say that the battery is (mainly) used for the
clock. However it is AFAIK common use to talk about the BIOS battery
and also it is (or was) a trick that if the BIOS data became corrupt
you could remove the battery to reset all BIOS settings.
But my question still remains. Where is the battery in my laptop.
