screen was replaced at another shop, i haven't gotten the computer yet. but apparently after the repair the touch-bar stopped working, as i haven't had any experience with touch-bars yet i was looking for some guidance, what should i look for, what could cause it. im assuming something got...

there is no one nearby im from kansas

ok i see how that tool works, but at the moment i wont be able to get that tool, do you know if anyone does it for a fee and if so how much?

i have never flashed a bios, how would i go about doing that? is there a video or a site for me to learn?

original board had no lcd enable, replaced with new board, and it wont boot to the os. it shows the folder icon, 'so the lcd was good like i originally thought" the problem is even with a working os it wont boot to it, it will boot to a usb os, but takes 10-15 min to get in, even to boot to the...

still no lcd enable, but i also notice pgood is gone again, usb lights up and i do get a chime, dont have a working lcd for this one, i have 2 cracked lcd's for backlight testers

i cant get lcd enable to be sent, i can force backlight, i reflowed u8900, but was missing some rails, so i replaced it and the rails showed up, i now have pgood, but no matter what ive tried i cant get lcd enable to come on. im almost 100% sure this lcd is fine.

no i touched up all the solder joints on u9000, i just touched up u8900 even tho it looked fine and its lasting longer than 20 seconds this time, "jumper removed ofc" so i guess i had a bad solder joint, but i wounder would my jumper have caused any issues?

i have a 820-3332 that came in for no power, after diag realized its powering on fully just no internal display, checked smc_lid and realized it was 0, repaired and got screen for about 30 seconds, then black. figured out after a few seconds i lost PP5VR3V3_SW_LCD_ISNS, so i jumped it from pin 2...

ok so i guess im gonna ask a stupid question. how does one remove corrosion under the plastic battery connector if ultrasonic does not remove corrosion.

i ultrasonic-ed it once already, should i give it another go? and this happens with all batteries i put in, so it cant be a bad battery

sorry inm not to sure what to do from there, the 10k resistor is good, so why is it not pulling down. jumping pin 1 to ground workes to stabalize battery power,

yes ppbus stablized and so did the power pins, tho it won turn on. im guesing bc its shorted to ground battery wont work

the 10k resistor is measuring 10k ohm and yes its pin 2 is tied to ground so it should be pulling down

sys_detect_l is jumping between 1.7v to 2.7

yeah only on battery, on ac its fine

pp3v42_g3h yes 3.41v ppbus_g3h is all over the place, from 12v down to 1 then back up

and on pin 17/18 im getting almost 0 resistance, on 27/28 im getting about 20 resistance

ac + battery = crash. ac only no crash. battery only wont power.

water damaged macbook, without a battery, works 100%, attach battery, battery % shows up and seams to be charging. randomly will shut down. if i measure the power pins on the battery while plugged in, the voltage jumps all over, leading me to believe there is a short but nothing seams to be...
