macbook pro A1989 restart when sleep and A1707 restart when shutdown

[kingskie]

Hello all,

I got macbook pro A1989 that has sleep wake failure..always restart when put in sleep mode or close the lid..if i shut down and close the lid there would be no problem at all.. already reinstall the mac os but still has the same problem even restore with DFU mode.

and for macbook pro A1707, this one always restart when i try to shut down..always restart when put in sleep mode.

can anyone help me? @piernov, @mon2 ?
thanks before

macbook pro A1989 that has sleep wake failure

Has this macbook an original Apple SSD drive or it has another brand of NVMe SSD? If the latter, it could be related to standby or hibernationmode settings (that can be tweaked with pmset command).

both of the macbook use on board ssd from apple.. i already tried use commend pmset but nothing changed

Check voltage level of PCIE_WAKE_L.

Most likely this will be an open-drain pin and is active LOW to WAKE up the host CPU. Respectively, the line will be high impedance for the 'high' state which demands that R1452 be present.

Check that R1452 is attached onto the PCIE_WAKE_L line.

Also check on the voltage on TPAD_KBD_WAKE_L. Consider to remove the trackpad connector to the logic board and test again. You should be able to turn on the logic board with pushbutton @ RE030 (attached).

There are numerous widgets on the logic board that can WAKE up the host. Search for and investigate each "WAKE_L" marked lines to confirm they are ok.

In the schematic, see:

TBT_WAKE_L -> QB201 mosfet (level shifter) -> TBT_WAKE_3V3_L --> voltage reading ?

Suspecting that one of these WAKE_L marked lines is parked @ logic low.

My bet is on the trackpad line. Faced numerous faults with the trackpads in recent repairs from small spills, etc.

i will check tomorrow...thanks @mon2

Hi i was checking the PCIE_WAKE_L for my A1707.
I am getting 3.15V.

Having this same issue of restart after sleep mode.

Search for the keyword 'wake' inside the schematic for the logic board.

Then measure the voltage to ground of each pin with this name.

If there is a '_L' suffix, then the signal is active LOW. If the pin is LOW, the logic board will wake up.

And vice versa if there is no suffix.

Update !

There was a problem with one of the rails. Turns out it was a BadCap. Removed it. Issue Resolved.

Thanks a ton.
