NM-b241 don't Power on completely , just 0.160 amp .
On board Ram
After taken some measurements , followig the power sequence PG47 , i reach only step 7...didn't find anything about step 8...at step 9 SUSP# is 0v ( enable signal for many steps )
i find too that PL501 is short to GND = 0.006 ohm ...so my suspecion go straight to this 4 little Samsung Semiconductor..
When i open this jumper PJ507 (= +1.2V ) the short is not from PU500..the consumption go to 0.950 amp than the lap is off .
So , i disable the ON BOARD RAM by shifting this 2 resistors :
RC1634 to RC1631
RC1635 to RC1632
After Closing the jumber PJ507 the short still there.
Don't want to remove this 4 little ram , is there anyway to confirm that the short is not from this 4 little ram !
Thank you
