Chosen Solution

Hey guys! I upgraded the storage of my Macbook Pro mid 2017 with sintech adapter (A1708) and Sabrent SSD. Since that I feel like I’m having a faster battery drain in idle than before. Can someone tell me how long their MacBook Pros from 2017 (with original storage) are staying alive without using it? Maybe I’m just wrong but I dont think so. Before some asks: I already did some changes to the system power settings. Are these right? System-wide power settings: Currently in use: lidwake 1autopoweroff 1standbydelayhigh 60autopoweroffdelay 259200proximitywake 1standby 1standbydelaylow 60ttyskeepawake 1hibernatemode 25powernap 1gpuswitch 2 hibernatefile /var/vm/sleepimage highstandbythreshold 50womp 1displaysleep 5networkoversleep 0sleep 1tcpkeepalive 1halfdim 1acwake 0disksleep 10 Update (11/08/2021) I installed SSDPmEnabler and terminal says it’s running correctly, but battery is still draining while MacBook ist closed. Rebooting is still not working. It shuts down but doesn’t boot up again. I have to press the power button myself. Afterwards macOS is showing a message that the system wasn’t shut down correctly.

This issue has been reported by quite a few people now when using an M.2 SSD with an adapter in this series.

I have the A1708 macbook and I’m using a Sintech adapter with a Sabrent Rocket Nano 1TB. Here is how I solved the sleep mode battery drain:

  1. I installed MacOS mojave using an external usb drive. Please note that the kexts below will only work on Macos Mojave or MacOS Catalina. For Big Sur and later is extremely difficult to make them work because you need OpenCore bootloader. Make sure you use only mojave or catalina.
  2. Install the following kexts: SsdPmEnabler, Lilu, NVMeFix
  3. run the following commands in the terminal:
  4. sudo pmset -a hibernatemode 0 standby 0 autopoweroff 0
  5. sudo pmset -a tcpkeepalive 0
  6. sudo pmset -a proximitywake 0 Before that I was loosing 2-3% battery in every hour, right now so far 6 hours and I lost 0% which means the standby is working correctly. The only problem remaining is the reboot issue, no answer for that yet but that’s not a big deal because you can use power off and power on.

There has been fixes for this. Check the info here: https://discussions.apple.com/thread/252… ——- quoted here below —————— Jan 11, 2021 6:21 PM in response to SunRahul

  1. Get the newest firmware, where power management is already better and/or some sleep/wake issues are resolved a) Either by upgrading to Big Sur (or in Catalina, Mojave the latest security updates) with your original SSD inside OR b) Upgrading Boot ROM Version without upgrading to Big Sur​

  2. Install tools which significantly lower the idle wattage for 3rd party SSDs a) SsdPmEnabler b) NVMeFix plugin inside lilu c) a+b combined reach an even lower wattage in most cases

That’s the short version of a meanwhile 8000+ post long thread in the Macrumors forums (!)

a) Either by upgrading to Big Sur (or in Catalina, Mojave the latest security updates) with your original SSD inside this has no effect on battery drain b) Upgrading Boot ROM Version without upgrading to Big Sur​ this also has 0 effect on battery drain 2) Install tools which significantly lower the idle wattage for 3rd party SSDs a) SsdPmEnabler b) NVMeFix plugin inside lilu c) a+b combined reach an even lower wattage in most cases these steps significantly increase the performance of the ssd and reduce the power consumption in the os but it does not fix the sleep / hibernate issue. Maybe we should try different adapters, different ssd manufacturers ? Or only original Apple SSD has the sleep functionality ? this is so stupid … why apple does this
