    samsung r538

    hi:
    this laptop with board model number: BREMEN-C REV:1.1 (100210)-4
    BA41-01218A GCE HAS THIS PROBLEM
    IT WAS TOTALLY DEAD , NO POWER NO CHARGING
    I CHANGED U4=ISL6255 , IT STARTS CHARGING , BUT WHEN REMOVING THE CHARGER , THE CHARGING LED WILL STAY ON AS IT IS INSERTED, ALSO WHEN POWER ON ON BOTH ADAPTER OR BATTERY , IT WILL WORKS FOR FEW SECONDS WITH FAN ON , THEN SHUT DOWN.
    I TRIED TO REPLACE: Q2 U503 WITH NO SUCCESS

      SO if dc is removed you still got led for bat charge , then you have SIO issues , chek CLK pins to battery must have 3.3 volts ~
      also if machine does turn on now , but then goes off , also chek bios , flash with new bios.
