    I made an account just to ask, are there MAJOR issues with the M2 (A2779) 14" mbps? i read some posts mentioning the TPS62180 buck converter from M1 laptops still being used.. i got a *very cheap* m2.. just wondering if i should worry about having it randomly die on me or if its just a infant mortality/water damage issue on these newer mbps. Thanks!

    Just take care about liquid ingress and do not let an external device connected when not really needed (turned off, or suspended mode).

    У меня были платы 00840/00875, на которых я получал выходное напряжение 1,1 В LDO только от одного CD3215.
    Иногда я проделывал трюк с портом, на котором отсутствовало напряжение, и это работало;
    Добрый день. А что надо сделать чтобы заработало какой трюк, спасибо

    For testing purpose, you can make a bypass over Q3100, or Q3200; depends which channel doesn't work properly.
    However, you MUST use a diode (connected correctly), if you want to use it in this way.
    If you leave it with direct bypass, will fry an external device connected on that port, when the charger is connected to the other port.

    Hello. New to this page. I’m at a loss. I accidentally erased my 2018 Mac mini A1993 T2 rom chip. And the back up did not save. I wanted to see if anyone might have the .bin file that I can flash to it

    SoC ROM is automatically reflashed in DFU mode.

    I restored it and had DFU mode rewrite it. I still can’t locate the serial number on the t2 rom chip while useing the programmer

    Hello kindly help me to understand can I replace my MacBook Pro mid 2012 corei7 logic board with corei5 logic board will the parts of corei7 work on corei5 perfectly?

    You can do that, if is the same board model.

    Good morning,
    I have a Surface Laptop 4 that doesn't turn on and doesn't charge, I haven't found a diagram or a board, if I connect the type-C power supply it stays at 5V (I think it should go to 15V?), by paying do you happen to have the possibility of find the diagram? (1953 mb rev 3.01) I found a line with the current pulsing. Thank you

    HI,I have an imac a1311 820-3126a which has a problem with the two USB ports and the Bluetooth, the camera, the SD card reader and the other two USB ports work, the components connected to the U3600 do not work,

    HI,
    I have a MacBook a1708 820-00840 that turns on with the question mark folder, the SSD is working (I have already tried with another SSD, same problem), I have the schematic and the board, I have no obvious short circuits, around the SSD the currents are correct apart from ISNS_3V3SSD_IOUT which is absent. What could it be? any suggestions? Thank you

    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

    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.

    Hi!
    I've problem on MacBook Air 2015 13" which randomly shuts down. Sometimes shuts down at loading screen. Sometimes shuts down after booting for 5 minute. Sometimes it works normally for 1-2 hour. But shuts down again. I can also recreate shutdown by moving the laptop. Battery is normal @ 509 power cycle and works for 5-6 hours. I've reinstalled OS, Reset SMC and PRAM etc. Can u pls tell me what can be the issue?

    I did all steps to Clean ME Region. But stuck on last steps for flashing bios file. Do u know what tool is required to flash New BIOS, Clean ME supported for MacBook Air 2015? And also I didn't find any video or steps to BIOS flashing in MAC?

    Hi! When checked in terminal using log show --predicate 'eventMessage contains "Previous shutdown cause"' --last 24h, I'm getting

    If turns off when move the machine, possibly broken trace, bad solders.

    You can use CH341 programmer for BIOS; need to remove the chip in this case.

    Hello, sorry if this is the wrong place to ask. Are you able to download files from Chinafix? I have an Acer IPISB-VR 1.01 MB and apparently the BIOS in the link below unlocks Ivy Bridge support. I believe these are the only two files that exist on that thread "ACER IPISB-VR 1.01.rar" and "BIOS_Gateway_P03.A3_A_A.zip". Please and thank you.

    Sorry, I don't have access there.
    Official website doesn't provide necessary update?

    Unfortunately no. The old Gateway site redirects to Acer now and they don't provide BIOS files. Web-archive has some parts of the old site but none of the files are archived or they redirect to Acer. Chinafix is the only place I found a potential download so far, everything else is just old links that don't work anymore or aren't archived either. I'll keep looking or I might just give up on the board. Thanks anyway!

    Did you try to search the BIOS by computer model?
    Don't make the classic mistake to look by board model; never do that!
    Same board may be used on different machines, with distinct configurations.

    Hey 2informaticos, I was referred to you from mon2 from Badcaps. We have a 2019 16" A2141 with an issue. Board turns on, and DFU REVIVE is successful on this board, customer wants the data recovered, we put the computer in Target disk mode and plug up a Thunderbolt cable, our A2141 sees the computers drive in disk utility however we get an error DISK CANNOT BE UNLOCKED DUE TO ERROR message.

    Also, the computer will boot loop when trying to launch or load OS, there is no login screen when we do internet recovery it downloads fully then when it launches it restarts, we tried an external and recovery and no luck, Target disk mode it does not restart but the drive won't let us unlock it.

    Sorry for delay, I didn't the message before.
    Find an workshop with Apple account; they can try to recover data in DFU mode.

    Hello friend, I have a problem with a 2013 iMac, I updated its disk and ram to SSD in the price, the display connection had a problem and it burned L9100, it was replaced and the fan continues without being on, can you help me?

    Did you test USB activity and external video?
