The Device had power on problems for a while, used to power only after re inserting Battery and will run on plugged in. All of suddenly it stopped powering on by any method. Upon opening I saw no visible problem in board or RAM, CMOS(new cell)... but found that Power switch board tiny LED is not working Has turned brown & almost no (just kindle) light via Multi meter testing. Is this at fault and reason for failure to power the Device, Battery health was ~40%

    First check the voltage output of the charger plug's outer ring and center terminal with the multimeter. Should be about 19 volts DC. Jack E/NJ
