    Apple MacBook Air "Core i7" efi request

    hello guys, got this Apple MacBook Air "Core i7" 2.2 13" (Early 2015)

    slightly liquid damaged. there was a rework before me. smc no edgebonding and the efi ic was not perfect in place.

    anyway replaced some resistors and caps what looked nasty. around smc and u7501 , u6101 r5177 smc tms.

    the main issue is here he takes forever to boot!

    after a pram reset at first boot up he boot little bit slower but he boots.

    after pressing the power button he needs 10-15 seconds until he chimes!

    replaced clear me from rossmann forum and changed fsys data line, after that he wont boot at all.

    thank you for your help and answers

      Is this the original dump? It just needed the ME cleaned properly, follow win-raid guide.

                                          Hello everyone!
                                          I hope this is the right section for this request. I'm looking for help to modify the boot logo on my ThinkPad T14 Gen 1.

                                          Hey everyone,

                                          Usually, I'm not the type to ask for help, but this time, I'm calling on your wisdom and expertise I've seen what this community can do, so I'm pretty sure you guys can help me out.

                                          Here's the deal: I noticed my MacBook got stuck in a boot loop. After opening it up and doing some initial troubleshooting, I found that the boot loop stops only when the trackpad is unplugged.

                                          Now, just so you know, the trackpad actually works — I tested it with another motherboard and it's all good. Same for the cable, no issues there. The problem is only...

                                          Hello,

                                          This special tool from Apple is used to recover data from Macbook A1706. I've been using it for a while but it stops working. When connecting Thunderbolt 3 between the tool and working Macbook, Macbook should prompt "new device detected, allow or not"... but it doesn't.

                                          Has anyone ever experience this ? It's not a cabling or power supply issue, some IC have stopped working but not sure which one. Probably the one that manager thunderbolt 3

                                          Thanks
                                          Claude...

                                          Macbook Pro mid 2015 battery required to boot?
                                          by twonk9098
                                          I have read many forums that state the Macbook Pro 2015 needs / does not need a battery to boot. I'm not convinced as yet which is correct.
                                          The Macbook Pro mid 2015 I have has no battery and do not really want to buy one just to test.
                                          This model has the newer trackpad which is not clickable when turned off.
                                          At the moment, without battery it does turn on with no display (with backlight), no chime and then turns off after 13 seconds. I see this from the power draw on my DTPS.
                                          If I hold the power button whilst connecting the magsafe 2 charger it turns on, again no image but...
