    DA0BLQMB6E0 REV E Cannot start or powered with ram installed

    Having a hardtime beacuse no schematic is available for this modem if ram is present laptop will power for a second then off. But without ram isntalled it will run the system at 200miliamp , Ive check the ram supply resistance its not shorted checking the voltage reading has 1.3v stable..

    What can it might be the closes problem?
    I also tried a new ram and different slot


    ALL BASIC POWER RAILS IS PRESENT without the ram.

    SIO is very likely bad . Not sure about this case but in lenovo this happens when sio goes bad.
