APPLE MacBook Pro 13,3 820-3115-B no chime, no video

10-20-2018, 04:26 PM

Hi, I've recently had a problem with my MacBook Pro 13.3 mid 2012.

MacBook starts, fan is running, MagSafe Led is green and changes to orange.
However, there is no chime and no video. Vcore I measured and CPU voltage, everything seems to be ok.

Can you give me a tip why it could be?

Apple 076-00236 Genuine Apple Data Migration Tool for MacBook Pro 2016 2017

by samstown

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

macbook pro M1 a2338 no video on internal display PP3V3_S2 short

by sdogs

Greetings to the entire forum, I ask you for help because I'm going crazy. A dear friend of mine gave me a macbook pro M1 A2338 that only works with an external screen. With the internal one, no backlight or image. Only the external display is detected from the system settings.
First I changed the display flat, then I made a backup with time machine and tried a reset in dfu but nothing to do, always the same problem.
I analyzed the logic board, it shows no sign of liquid or visible damage. I then moved on to examine the logic with the thermal camera and found that the UP701 chip was...

Macbook A1398 - no startup chime, no boot, but have fans and CPU warm

by survivalbloke

Macbook A1398 - had repeating loop of startup chime with no actual boot. Just startup chime, then restart, start up chime, then restart, etc. I pulled the battery and cleared BIOS. It will now power up, fans on, CPU warming, but no startup chime and no boot. I reflashed the BIOS chip but the same thing happening. Where should I go from here?

Apple MacBook A2442 faulty PMIC - Question about possible replacement

by arahban

Hello Gentlemen,

I am working on an apple MacBook A2442 board pn 820-02098-A with a visible short on the PMIC U7700 MVK-PLUS as per the schematics

I have a donner board from apple macbook pro m1 A2338 PN 820-02020 and I saw that the PMIC U8100 TMLT46B0-JPE could be a possible replacement for the U7700

Can you please help me confirm if the U7700 can be replaced with U8100 ?

APL1098 is it the same as APL1096

Thank you very much in advanced

Ahmad
