I forgot to mention that the Pixelbook will wake up if it's only been in sleep mode for up to a few hours. But longer than that, or overnight, and it will not wake up.

Is your pixelbook not plugged to power when trying to wake?
b/36723679 indicates this might be WAI when unplugged from power.

The Pixelbook is definitely plugged into power. It stays plugged in as I rarely take it out of the desktop configuration with keyboard, mouse and external monitor.

I have noticed some variations to the circumstances since I first posted this.

1. If trying to wake it after being in sleep mode all night, it rarely wakes up, but once out of maybe 10 times if I press the keyboard keys or move/click the mouse 30-40 times, it "might" wake up.

2. If I leave the Pixelbook display open, the problem never happens. It only occurs when the Pixelbook display is closed in the clamshell mode.

3. I originally thought it wouldn't turn on nearly all the time during the day, but I've found that if I repeatedly press a key or move/click the mouse it will occasionally wake up, but it will take sometimes 50-60 keyboard or mouse movements for this to happen.

4. I've tried two other keyboards...same thing.

5. It wakes up just fine all the time if I use a Bluetooth keyboard and mouse (which I don't want to do).

After reproducing, can you send a feedback by Shift+Alt+i and mention the bug id - 912123 - in the form's text box.

Unable to reproduce this issue, as testing was done with short term(30 mins, 2.5 hrs) and long term(2 days over the weekend) suspend cycle on two pixelbooks (M70 and M72). 

larry.mcjunkin@, can you specify the connecting adapter you are using. Also are you charging through the adapter? Can you try using different adapter?

I think the problem is with the monitor's USB port. I assume after a day of inactivity it goes into some sort of low power mode and fall out of USB bus. Dut on waking from S3, realizes that there is no external monitor connected anymore and slips back to suspend.  

larry can you please generate a feedback after a resume. That would help us a lot. 

Ravi:

It may not necessarily be the usb data portion of it, but the DP portion. If the DP controller thinks the monitor has disconnected, then upon lid closed suspend all external USB devices are intentionally wakeup disabled.

This is to prevent a wireless USB mouse dongle attached to a Chromebook from constantly waking the system when it's in your bag with lid closed.

We should be debugging potentially why the monitor is registering a hot-unplug, perhaps.

Larry, have you filed a feedback report? I notice there are no logs attached to this bug.

I've been out of pocket for a couple of days, but in catching up, here's some follow-up comments.

1. @ka...@chromium.org - I'm not using a USB port on the monitor. The only connection from the monitor is the HDMI cable to a high-quality mini-dock that has and HDMI, two USB-A, and USB-C ports. Before possibly blaming the mini-dock,I've removed it and used nothing but an HDMI-to-USB-C adapter for the monitor. Same problem.

2. @bleung@google.com - If I had to side with any assumption, it would be yours. But my geek career was in an entirely different space, so I really don't know.

3. I did a powerwash after trying the beta channel again (for something else) and now the behavior seems a little different. Now, the USB Apple keyboard still does nothing...I can pound on it for five minutes and it will not wake up the Pixelbook. However, now if I click and move the mouse five or six times, it wakes up the Pixelbook, even after a full night's sleep. But that said after I click/move the mouse a few times, I have to wait about 5-10 seconds for the monitor to turn on and display the login screen. Something is causing the monitor to be slow coming out of it's suspend mode after the mouse action waking the Pixelbook, which it's definitely in (per on-screen display when going to sleep).

Based on these comments, please let me know what you would like me to try. Thanks 

Think we need a feedback report to make progress here.  Be sure to mention crbug.com/912123 when filing.

I've tried repro w/ a USB-C -> HDMI + 2 USB Type-A ports + 1 USB-C power and was able to wake repeatedly with both a apple USB keyboard and logitech USB mouse connected to the minidock.

Will have to do in a day or two...traveling now. Just a note that there is NO problem when I used to use a Bluetooth Apple Keyboard and Bluetooth mouse. The problem started when I began using a WIRED Apple keyboard and WIRED Logitech mouse.

To reiterate, I can wake the Pixelbook with the wired mouse...though it always takes five or six taps on any button. I can press keys on the wired Apple keyboard for as long as I want and it won't wake the Pixelbook.

Thank you for providing more feedback. Adding the requester to the cc list.
