Surface book 2 power button not working unless I detach and reattach

Hello Joe,

I ran Diagnostic tool its all good. tool could not detect any problem.

I don't know much but it seem that NVIDIA GeForce GTX 1060 has some connection with detach button.

if I disable GTX 1060 display adapter and ignore surface detach taskbar error, button works just fine.  Not sure that's a right way to run it.

Hello Nilesh,

Since you already took your device to a Microsoft Store and have them inspect your device's concern about the Detach button functioning as a Power button, pleas run the Surface Diagnostic Toolkit. This toolkit may resolve Surface concerns.

I need a help with Surfacebook2 Detach button issue started when it got updated to 1803.

Here is the issue. 

when surfacebook2 is shutdown under docked position. now pressed detach keyboard button while surface book is power off:

-->> surfacebook2 power ups as if pressed power button and detach button turn red, upon haft way boot up detach button turns green and display disconnect from the base keyboard.

when sb2 is shutdown in un-docked position. docked it back on keyboard, now pressed detach keyboard button while surface book is power off: -->> sb2 undocked as it should with green flashes 

when pressed detach keyboard button while surface book is on:

-->> surfacebook2 detach button turn red and then green and display disconnect.

from device manager I disabled NVIDIA GeForce GTX 1060.

surfacebook2 detach button works just fine in any condition surfacebook2 on or off. except due to disabled NVIDIA surface detach button error pops up on task bar

to resolve this issue I did updated suracebook2 with latest firmware 18_022_09

talked to Microsoft phone support about 3hrs - virtually not helpful  - I feel they don know what they are doing.

stop by at local Microsoft Store tech support - guy says seat tight - next firmware may resolve the issue

Any help will be appreciated

I fixed the problem after hours of talking to surface tech

Surface Book 2 15 ich

so the problem is because of the graphics card drivers not being recognized, try this, 

go to device manager 

then display adapter,

if you don't see NVIDIA GeForce GTX 1060 then you have a graphic driver issue.

what worked for me was first under divice manager uninstall everything under other devices, so all the unknown devices are uninstalled, 

then reinstall the graphics card, here is the name of the file to google 

SurfaceBook2_Win10_17134_1802209_1

then after installed and restarted your computer, detach the keyboard and restart the tablet by itself, wait until it is loged in to windows then attach it,

to make sure the problem is solved see if the NVDIA drivers are back from device manager

GOOD LUCK!!
