Surface Book 2 won't wake up from sleep. Only by detaching the screen I can wake up.

Hi Mark,

Thanks for your answer.

I tried the Power Troubleshooter, it worked but it didn't help. I tried cleaning the connectors too but that didn't solve the issue either. Also, I tried restarting in clean boot, but I saw no difference...

If I have the tablet detached, I cannot turn it on either, so the connectors should have nothing to do with it, since I should be able to turn on my tablet independently of the base. One thing I've noticed is that it seems like whenever there is a powering change (connecting/disconnecting power cable or detaching/attaching the tablet) the surface seem to react to it and wakes up as soon as I press power right after that action. But otherwise, no reaction at all...

Please help! Any more advices?

Thanks for your advice! Unfortunately turning off facial recognition didn't solve my problem...  Best,

I have this same exact problem with my Surface Book 2 15".  I even went as far as resetting the computer from scratch, which only temporarily fixed the problem.  I found that if I turn off facial recognition I don't have any problems.  I haven't tried Mark Ole's solutions.

Hi Jon,

Running the Power Troubleshooter automatically checks Windows power plans and detects your system settings that affect the power usage. To run the troubleshooter, follow these steps:

1. Go to Settings.
2. Click Update & Security.
3. Choose Troubleshoot.
4. Click on Power, then click on the Run the troubleshooter button.

If running the troubleshooter doesn't work, run the Surface Diagnostic Toolkit. Click on this link on how to run the toolkit.

Also, poor connection between the contacts can cause this issue. Try to clean the connectors. More info at  Surface won’t turn on or wake from sleep too.

1. Detach the Clipboard from the keyboard.
2. Wet a cotton swab with rubbing alcohol. (Use 95% isopropyl alcohol or higher if possible.) Clean the silver pins on both faces of the three connectors located on the top middle surface of the keyboard hinge. Rub the cotton swab back and forth vigorously to clean the pins. Use a fresh swab to clean each of the connector faces (six in total).
3. After you're done, make sure the pins are dry and that there are no cotton fibers on the connector. Reattach the Clipboard to the keyboard.

Performing a clean boot may also help resolve the issue. It is performed to start Windows by using a minimal set of drivers and startup programs. This eliminates software conflicts that occur when you install a program or an update or when you run a program in Windows. On how to perform a clean boot, click on this link.
