Switch lite won’t stay in sleep mode

switch lite was stuck at logo screen, reflowed the Wi-Fi IC and it worked fine at first. I noticed that when I press the power button, it would go into sleep mode for about 3 seconds and then turn back on. If it’s important for context, the switch is disassembled (except for essentials), the Wi-Fi works, and I did not apply thermal paste yet as I’d like to fix this problem before closing the shell.

hours pass and I test the power/volume board (it’s perfectly fine) but now I notice that it stays on the switch logo AGAIN until I plug it in. maybe I need to reflow it more?

My biggest fear right now is that I removed a capacitor by accident with my heat gun.
