Could somebody please tell me what does the cable do? Is this fixable (probably by microsoldering in local repairshop) or is it usable from now only while plugged in?

Thank you.

The pad via's have continuity with the via's to the corresponding test points

The problem is the laptop charges, works fine on battery power, but there is an X over battery, and does not give charge or % data. Im assuming a data line for battery status is having an issue somewhere.

Any one have any advice where I can look next? Im all out of ideas ;o/

Attached is the corresponding schematic area of the logic-board

Hi OT, sorry for bad photo. The original photo was before any work was done. the pads were in fact bridging, but here is the rework. the only pads not connected are the back legs, which are presumably to ground pad, but schematic reads No Connection.

Here is the reworked version

Hope this finds everyone well. I broke my A1990 screen, I'm trying to get a replacement.

Can you please help me, which screen should I get so that the Mac doesn't get bricked.

Can any used A1990 screen work?

Thanks so much

Hamid

Guys, what are the odds that it could explode? The battery already needs to be replaced, since it has about 950 cycles, but I would like to use it for a couple of days. Thanks.

i have an old macbook pro 2019 15 inch, new sealed, stored for almost 5 years plus, decided to use it,

but battery cannot get charged, i think thr battery cell already freeze?

anyone now now to jump start the battery using lithium ion charger or power supply?

if i give charging voltage between the battery and the battery board, will it destroy the battery circuit?

I am referring to the battery daughter cable. I will attach a photo with it circled in red. I unplug one end of this cable to get the laptop to start with the wall charger. Then I connect it while the laptop is running. That is when the battery shows up and says it is charging. I installed coconut battery and I have attached screens shots from it also.

it felt liquid on my laptop and i really need the schematics to see if i can save it.

Thank you very much.

I'm wondering if there any way that I can save one MBP. I was on a company and the company went bankruptcy, they told me to keep the computer but I cannot reset it since it's password protected and I cannot access the tools on the booting since it's password protected.

Are there any options to make a hard reset?

Thanks in advance

Unfortunately I don't have access to computer. It's like it's blocked or disabled and the password it's protected.

My Macbook Display Assembly had somehow got liquid inside it. I checked the internals of the Macbook to see whether the liquid had found its way inside, and there were no visible signs of any liquid within the Macbook. So I thought great, I'll just replace the Display. Worth mentioning that the Macbook was booting with no issues after checking the internals.

Since changing the display, the Macbook when powered on has been displaying the Apple logo for no longer than a couple of seconds, then restarting itself and going through that process repeatedly until it is manually switched off by holding the power button down.

I tried resetting the SMC, that did nothing. Resetting the NVRAM/PRAM seemed to have an effect, but only as far as preventing the Apple logo from showing up at all - instead I just now get a faint grey background on the screen as the backlight comes on, with no Apple logo.

The machine is completely unable to boot into either local or internet recovery mode (as I was initially thinking the disk may need first aid if the machine is restarting as soon as it attempts to boot into the drive).

Local recovery mode (CMD + R) simply does not boot (the Macbook just continues restarting itself before it can boot into recovery mode), and Internet Recovery starts off promising - getting to the loading bar 'starting internet recovery, this may take a while' - gets all the way to the end, then either restarts itself and goes back to its original restarting state, or gives me the error -1008f. I have tried both CMD + OPTION + R, and CMD + SHIFT + OPTION + R.

Error -1008f seems to relate to internet connection, however I have already tried with both WiFi and via a USB-C to Ethernet adapter. Both yield the same results. the Macbook also gets incredibly hot towards the top of the palmrest closest to the screen, and the fans spin on what sounds like full blast while the machine is trying to load internet recovery.

I have also tried connecting the machine to another Macbook to use Apple Configurator to try a revive the problem Mac, but it does not seem to want to boot into DFU mode, rather just goes back to its restarting every 1-3 second phase.

At this point, I am thinking a faulty logic board is the only possible outcome - is there anything else I can try?
