no turn on :( no PP5V_S3 no PP3V3_S3 q7260 : 12v - 3v .....

sorry , yes i have no ground on l7220 and 0v but when i plug battery i have 3.34v on l7220

no answer ......

ground its OK around u7200 (resistance and capacitor ) u7200 voltages : 1) 0v 2) 0v 3) 2v - 0v 4) 3.34v - 0.700v 5) 0v 6) 0v 7) 0v 8) 3.34v - 0.700v 9) 3.34v - 2.60v 10) 186mv - 0.1mv 11) 186mv - 0.1mv 12) 4.1mv - 0v 13) 3.38v - 0.334v 14) 2.17v - 0.1v 15) 0v 16) 12.64v - 3.00v 17) 5.02v -...

no tension L7220 0v

Yes, the battery is present , light orange pin 17, 18 = 3.1 ohm pin 27, 28 = 20.2 ohm

yes ! Voltage drops from 12 to 3 after a while . 2 seconde i come back tomorow, i go to sleep thanks you for your help

pin 17 = r7052: 0.2 ohm pin 18 = r7051: 2.5 ohm pin 27 = r7022: 10.2 ohm pin 28 = r7021: 10.0 ohm i know use multimetre but i speak little in english ;)

No Title the schematic it's ok ? what do you want i don't understand

i don't understand . Everything is in place pin 17: 12.63v down 3.14v pin 18: 12.63v down 3.14v pin 27: 16.64v down 4.19v pin 28: 16.64v down 4.19v the sames mesures on resistances

i need you .....

when i take off r7020 . i mesured r7020 pin 1-3 : 1.4v pin 2-4 : 16.64v. ok u7000: pin 17: 12.63v down 3.14v pin 18: 12.63v down 3.14v pin 27: 16.64v down 4.19v pin 28: 16.64v down 4.19v

i have remplaced all resistance around u7000 same problem, i have 12.64v - 3.14v on f7040 and r7086 thanks

hey, i have remplaced u7000 and r7005 . now ! green light ;) but on fuse 12.64v - 3.14v ..... no fan :(

u7000 pin2: 0.9v - 1.8v r7005 pin1: 16.56v - 16.99v pin2: 0.9v - 1.8v

d7005 and r7005 ok short ground : c7050, R7001, R7052, R7051, C7000, C7001

i removed F7040 and I took the measures U7000 : 1) 15.11v - 15.49v 2) 0.8v - 1.5v 3) 4.02v - 4.07v 4) 3.41v 5) 29.4mv 6) 3.42v 7) 56mv 8) 93mv 9) 0.00v 10) 3.38v 11) 3.36v 12) 3.41v 13) 0.6mv 14) 0.6mv 15) 48.9mv 16) 18.7mv 17) 1.4mv 18) 0.9mv 19) 0.9mv 20) 1.1mv 21) 0.00v 22)...

hello, i have logic board 820 2879 with PP18V5_DCIN_CONN move up and down. no green light , no fan thanks

yes, i have good trackpad

5V_S5_CUMULUS = 0v PP5V_S5_LDO = 5.12v L5800, C5800, R5805 = 0v U7801, C7801, U7200, C7273, Q7840, C7841, R7842 = 5.12v L5800, C5800 = No components thanks
