Where is the jumper to disable write protect located on the ASUS CX1500CKA motherboard?

Is there any serious reason not to open the unit this way? I opened it once and closed it up again and the fit is still tight and it still works, I just couldn’t find the jumper. Is it microsized?

Some of these models (listed as Jumper without a clickable Jumper Picture link) may not even have holes for you to jump and disable WP - your only option might be CR50
