Macbook Pro M1 wont wake in clamshell mode

Hello, man.

My problem was the same.

It was solved when I used the power supply in a thunderbolt port. Both the original apple power supply and other supply (Baseus 100W) connected via the thunderbolt port work. However, when I use magsafe, clamshell mode stops working.

I hope it helps you!

Ok. I found the issue. If you use a keyboard / mouse (in my case logitech) that isn't a USB-C and requires you to use an USB/USB-C adaptor, the system will not always see it when it's asleep. I purchased, against my wishes, an Apple Magic Mouse and Keyboard and now the system wakes up with a simple click on the mouse.

Apple (Tier 2) says there is a tech note regarding this. SO, that means all of the OS's up to ventura had the code for the older USB's but with ventura not so much.

I have the same problem, and it does not have to do with monitor wakeup time. It worked properly in Monterey, the monitor would wake up in a few seconds. In Ventura it doesn't work at all. I have to take the Mac out of it's stand on the shelf, open it and press the fingerprint reader (2019 MBP 16), then I can close it and put it on the shelf. It will wake up after brief sleep, but not after it has been sleeping for a prolonged time.

This is not long term viable and I would consider this a massive bug in Ventura. A solution is needed ASAP.

This solved the issue for me. Thank you! Such a random solution: plug it into power.

Hey there boltsthrower,

The amount of time it takes for your monitor to respond may be related to the monitor itself.

Check around for your specific model to see if there are any settings that can be changed on the monitor itself.

Regards.

Hello boltsthrower,

Thanks for reaching out to us in Apple Support Communities about your MacBook Pro not wanting to wake up. We're happy to help by looking into this more! 

Here's a resource that can help: If your Mac starts up to a blank screen - Apple Support

Apple silicon

1. Press and hold the power button for about 10 seconds, until you see the startup options window, which includes a gear icon labeled Options. Select Options, then click Continue.

2. If you never see the startup options window, release the power button, then repeat step 1.

Hope this helps.

Best Regards.

Well, I'm having the same issue. Macbook M1 2016, LG monitor, Logitech keyboard and mouse, vertical Ascrono docking station. Sometimes I just need to click the mouse and it wakes up. Other times, like right now, nothing I do wakes it up.

Sadly, I'm typing this complaint using my work provide Thinkpad and Windoze system that NEVER has this issue.

To add: I've removed the Macbook from the dock, plugged the keyboard / mouse wireless USB dongle and HDMI for the monitor directly into the Macbook and it still will not wake up. (The dock is not the problem)

I swapped mouse and keyboards to a different type and that doesn't help. At this point, I can only use my Macbook pro in laptop mode. Do I need to take it to a Apple store or return it?... This thing cost me >$3k
