    First you need to be sure that the battery is working, but after what you write it is not.
    Apple does not provide the ability to modify the BIOS, much less upload. As far as I know there is a simple (literally) BIOS and the rest is on the disk with the system.
    Diagram attached. I didn't find CMOS battery.
    On page 46 there are temperature sensors.

    From the power supply itself (without batteries) this model must work.
    They have not used CMOS batteries since 2008.
    This is not a BIOS issue
    There are no sensors on the cable.

    This type is so because the cooling system in this model is weak (no thermally conductive tube). Under load, it can grow to 100.

    Insert the NS directly into the charge and load it with the programmer or via the AST_BBS program.
    Original charger?

    I will own the REPLACEMENT charger today :)


    Especially on Macs
    according to several people, this is the best way to solve problems, and if smc falls it's "full of happiness".
    I recommend Luis Rossmann's films with youtube.
    The charger must be original because saving on it can be very expensive.

    well ... the power supply is not detected by SMC. For this it does not work properly. On medium pin what voltage?

    It does not matter if the replacement or the original, there must be 3V on 3 pins (without this the power supply will not be detected). Only 3V gives no power supply, but a laptop.

    Hello everyone. Apologies for my message in English but I cannot speak Polish.

    I wanted to thank for this topic and contributors, I have managed to enter the missing serial number of my MBP and I can now use iCloud services, Facetime and iMessage.

    Dziękuję Ci bardzo. :please:

Topic summary

The discussion revolves around troubleshooting a MacBook Air (A1237, late 2008) that fails to power on normally. The user reports no LED indicators on the MagSafe power supply and suspects a damaged battery, which shows low voltage. Various methods to power on the device are explored, including holding specific keys during startup. After running Apple Hardware Tests successfully, the user replaces the battery, restoring most functions but still faces issues with charging and the MagSafe LED indicator. The conversation includes insights on the cooling system, temperature management, and the importance of using original chargers. The user ultimately seeks assistance with ongoing charging issues and the absence of a serial number.
