    820-4924-A MBPr 2015 running slow, possible ME Region?

    MBPr 2015 13" Early 2015 820-4924-A

    Running slow, with SMC bypass works fine:

    It has a NVME SSD Crucial P2 (1TB), tried another NVME adapter too.

    - No water indicators tripped
    - Sensors using iStat /HW show sensible values, only airport showing 129 degree (which is common) since we don't have ASD for this year board.

    I have removed and dumped the EFI/BIOS:
    - does cleaning the ME Region make sense?


    Side notes
    1) I do not have the original nor compatible SSD to test with
    2) battery is showing service battery (it's down to 3700mah) - do not have a compatible one to try
    3) Tried with the Camera cable disconnected
    4) Wondering if booting from USB3 externally with internal SSD removed can help understand if it is a SSD issue.
    5) using genuine 65W MagSafe2
    6) Trackpad cable replaced since the last one was ghosting

    Thank you

              Yes, i already saw that.
              Also, I saw you've committed another rule violation, because you are not allowed to make a new topic if there is an existing one.
              I've already moved your request.
              Be careful, read the rules!

                  Try a serviceable battery first. Also run diagnostics with D at bootup to see if there are any errors reported.

                      by smic717394
                      Hi,

                      I need a bit of help. I have a Macbook pro end 2011 8.2. I bought it of a customer cheap because it has a bulged battery. I replaced the battery and upgraded the ram 2x8GB total 16GB, and replaced the HDD with a SSD. What happens with this laptop is very strange and I don't know where to begin. The laptop doesn't panic, tha fans run normal even when the kernel is 100%. If I reset the SMS, will run normal for about 30 to 1 hour then the kernel_task goes to 95% and the laptop become unusable. If I reset the sms agail will run again normally for some time. I thought is the battery,...

                      Clean ME region - a bit of theory
                      by Adenitz
                      Hello laptop repair experts,
                      can someone plese, help me understand the significance of cleaning ME region in a BIOS dump file?
                      I know that Manegement Engine (ME) data is part of BIOS/UEFI firmware. I know that it contains some HW specific data for the particular laptop.
                      What I don't know, why do I need to clean ME region if I try BIOS dump file from another laptop (of course same type and model). I'm not sure if this is only because of the serial number (not sure if that is stored in ME region at all).

                      Recently, I had a two cases where laptops (one is Lenovo Idepad...

                      by platinumsteel
                      Hi guys i have my personal MacBook Pro 2015 820-00165 board that was working fine for more than a year and one day stopped working on my original Magsafe charger. It was turning on with my bench power supply. Opened it up and while diagnosing that somehow i ended up with a shorted smc.The line which was shorted was SMC_PM_G2_EN. I removed the SMC and short was gone. So all I had was another working donor board 820-3435 which i used to program it's SMC to 820-00165 using the SMCTOOL By MuertoGB.Took that SMC and use it on my 820-00165 board .And my board started working again.

                      Hello
                      Can someone help clean the ME region?
                      I flashed the BIOS with this file and writes intel me unconfiguration in progress when loading
                      I wanted to try to clean the region myself, but I don't know which and where to get a file with a clean region for this motherboard. And what version do I need?

                      MacBook Pro A1708 - CPU extremely slow, locked @ 0.39ghz; fan full speed
                      by gjlpereira
                      Hi forum.

                      I'm working on a macbook pro, model a1708, that is running extremely slow.

                      Everything on it seams to work just fine, it just works extremely slow; painfully slow; especially running macos (windows and linux actually run OKish on it, slow, but usable).
                      One other symptom of the problem with the machine is that the fan is always running at full speed.

                      This machine has been worked on by someone else previously; they tried to repair it, but with no success. The motherboard does have sings of being worked on, but it all looks good/OK; like...
