    heyho,

    i've got a
    MBP 13" mid 2012 A1278
    8GB RAM
    256SSD
    OSX 10.9.4

    the MB was charged one time with an replica charger, after fully charged the MB runs fine till instant powerless (no led, no response, no magsafe led...).
    First i thought -> completly death.
    After a short battery unplugg the MB cames back to life an seems to work fine again.
    But unfortanetly the Issue repeats 2-3x/week

    The powerless state comes when the MB is on bag or something else and does "wiggle" the internal parts. i think thats the only reason.. other things like temperatures does not affect this.

    SMC/PRAM Reset didnt solve the issue.

    I think its a loose connection or a battery issue (but why the magsafe led is also off?)... maybe a motherboard issue :(?

    My next steps would be:
    -try another battery
    -disassembly motherboard and look for some liquid (its not mine book) and clean with isopropanol.

    thanks a lot!
