È probabile che si tratti del coperchio inferiore che flette e va a toccare la RAM. Se ha preso qualche botta sotto è più facile che accada ma può anche dipendere da "cedevolezza" dell'allumio che ha ormai anni di sollecitazioni e anche da come viene preso per sollevarlo. Se sollevandolo facendo attenzione a tenere le dita lungo i bordi non accade, dovrebbe dare la conferma che si tratti di quello. Si può provare a togliere e riposizionare il modulo superiore della RAM, nel caso non sia ben ferma nella sua sede. Se il fondo è ammaccato andrebbe forse sostituito. Sui 15" Apple ha previsto distanziatori sul montante in alluminio che separa batteria e scheda logica, mentre sui 13" ha ritenuto non fossero necessari probabilmente perchè più compatti.

No, se non si avvia senza batteria è guasto, funziona normalmente anche con il solo alimentatore avviandosi automaticamente quando il magsafe viene collegato.

Usb ports have different pins that connect to different independent rails on the logic board: power, ground and data, thus it can still supply power without exchanging data. There are 2 Usb ports on your Mac and you don't say whether both show the same issue..if that's the case it's very likely it's a logic board failure higher up in circuits of the logic board. If one works fine, check the pins of the faulty one from close and with a good light source, to check no pins are bent or oxidized. If you see dirt or oxide, try cleaning it with canned air and deoxidizing spray for electronics. Yet it might happen some final components have gone bad on the logic board for one single port only, each one has independent IC, resistors and filters.

Nope, unfortunately the 2015 topcase is not compatible with the A1502 of previous years/series. Trackpad is different and cannot be swapped either.

Try different CDs and DVDs, superdrives that haven't been used for some time may become very picky, but once they start working things may get better. If it spits out disks it means it's unable to read them, usually that's due to a dirty lens. Easiest disks to read are the original music CDs, if it spits out those too, there's not much to do except tearing the superdrive apart and clean manually the inside. If if works with music CDs, next step would be to try using a lens cleaning CD.

The only method would be to wire positive to positive and negative to negative of both batteries. In theory 2 working batteries should balance their power until it gets even, but if you have one dead battery it may not work. However, unless you know for sure the dead battery is not internally shorted or deteriorated, I would avoid playing with lithium batteries, as they have the bad habit to catch fire when things go wrong.

To put it plain and simple, a Triage mode doesn't exist. You could put your Mac into recovery mode and reinstall the OS, but that doesn't solve your needs, as in recovery you can't access your files to selectively decide what to keep and what to delete. Thus to reinstall the OS, since memory is full, you would need to wipe all data. The alternative would be to start your Mac from an alternative medium, such as a pendrive or external hard disk, where there is a working operating system and from there access you internal drive as if it was a side storage. You would need to have or buy a drive, boot in recovery mode, https://support.apple.com/en-us/HT201255 , format your external drive as Mac Os GUID partition and choose it as destination for installing a new operating system. Once that's done successfully, you can choose the external drive to boot from by pressing the Option key at startup and from there you will eventually be able to see and modify your files in the internal drive. Good luck, hope it helps.

Puoi provare a verificare, tanto non hai niente da perdere e presto o tardi dovrai aprire comunque l’iPhone se vuoi fare da te, ma che si stacchi il connettore per una caduta è molto improbabile anche perchè tenuto in posizione dalla piattina a vite. Al 99% si è semplicemente rotto lo schermo. Potrebbe anche essersi guastata la scheda logica, non molto probabile ma non c’è modo di verificarlo senza un display funzionante.

O il tasto è difettoso o è montato male. Suggerirei di rimuovere quello a fianco e con un ingrandimento e una buona fonte di luce confrontare i due tasti per capire dov’è il problema.

C’è una guida passo a passo per questo lavoro, che è classificato come molto impegnativo e richiede saldature a stagno: https://it.ifixit.com/Guida/Sostituzione...

Nice guide, thank you, very helpful. There would be no way to guess where the glue stripes are located and a couple of connectors are very difficult to spot. I don't see any need to remove the antennas and the speakers though, they are not really an obstacle to remove the board and can be left in place. The lightning connector is secured in place by two other two horizontal screws which are not shown in the guide.

Thanks again !
