Reset the Computer to Factory Default State
If the computer is unresponsive and all other recovery methods have 
failed, you probably need to reset the computer to the factory default 
state. 
When you reset the computer to the factory default state, all personal 
content is erased and all factory default settings are restored on the 
computer. The reset discards any account information you may have 
added, including your Microsoft account information. Only installed 
Microsoft over-the-air (OTA) updates persist after you perform a reset.
1 Press and hold the Volume Down and Power buttons 
simultaneously until a large exclamation point appears on the screen.
This process can take quite a while, but continue to hold down on the 
two buttons until you see the exclamation point.
2 Press the following buttons in this order: 
a Volume Up
b Volume Down 
cPower
d Volume Down
Once the computer resets, the language selection screen appears. 
You need to set up the computer again.
Caution: Resetting the computer to the factory default state erases 
the memory on the computer, including all applications and data 
files with the exception of the information found in any removable 
storage. You must reimplement any custom provisioning after 
resetting the computer to the factory default state.
