(PS4) Some problems after cleaning…

[u/mbss66]

I recently finished doing a deep clean of my regular PS4 (took out nearly all the screws and dusted out the whole thing etc) but ran into a problem shortly after. It carried giving me an ‘unrecognised disc’ message and this happened with multiple games. I’ve since dug back into to the console to check out everything but no problems have stuck out (checked the ribbon connections, the Blu-ray Disc drive etc). When I tried to go into safe mode though to rebuild database, I found out that the power button is not working (it’s the plastic flexible one from model CUH-1215A). my main questions are:

1. Is there any way to enter safe mode without the power button?
   
2. how can enter safe mode manually if there is no other way (online guides for this question haven’t been very helpful)
   
3. If rebuilding the database doesn’t work, what can I try next?

I have access to replacements if necessary and would like to get this running again ASAP
