    I have already checked continuity in diode mode of the filters l4720, l4611 etc and there are no problems, the currents around the U3600 seem good, 5V arrives on the USB ports and 3Volt on the Bluetooth. What can I still check?

    Hi, I bypassed L8600 and L8602 even though I had the correct currents at both ends but I didn't solve the problem. I'll give you the measurements I checked.

    Salve, innanzitutto grazie per la risposta, ho un adattatore con SSD M2, l'ho provato per escludere un problema con l'SSD originale. Farò i controlli e gli esami da te suggeriti. Grazie
