Hi, i need the capacitor values. There are two small ceramic capacitors on the left. I need the codes of them. My motherboard is missing them.
Please take a look at the picture. Thanks!

these are the oscillator load caps, I will look tomorrow my board and report back - unless someone beats me to it
should be something like 12 or 22 or maybe 33pf

80pF is too much for such capacitors. Most meters are unable to accurately measure capacitances below 100pF, since all sort of parasitic capacitances get in the way.
12...33pF is the ballpark, 18 and 22pF being the most common values. Using wrong ones will just mean the clock freq is off by 0.0something%

I just checked on mine and they seem to read 0.080 nf, so maybe 80pf?

Hi, thanks! Did you checked using digital multimeter?
What are the labels on the capacitors?

80nf is way too much - like Tiido says , what is the marking on the cap Thermalwrong ?
Mine are 10pf:

Thanks, I will put 10 pf then.
And the battery is CR 2032 - right? I'm missing battery as well - the original has leaked long time ago. That's why I'm trying to repair the board now. The transistor TIP32C near CPU socket was broken as well 😀
