关于android studio不能launch avd emulator的解决办法

花了一个小时，快把我搞死了，记录下来。

Check whether virtualization is enabled or not:
cmd, input “systeminfo”
find the Hyper-V Requirements: 4 yes! It’s done!
If the second is no, then:

1.Go to the SDK directory
extras\intel\hardware_accelerated_execution_manager
First run haxm_check.exe and check whether cpu support haxm, should have two yes.

Run the file "intelhaxm-android.exe’, choose to remove it;

2.Go to BIOS and turn on virtualization
This part takes me half an hour 'cause I cannot find where the virtualization is!
For lenovo thinkpad T-series.
Switched to the Security Tab, not Config Tab!

Steps:

1. open settings -> update and security -> recovery -> advanced startu
   -> restart now -> troubleshoot -> advanced options -> uefi firmware settings -> security tab -> find virtualizaion/

2)enable it, F10 save and exit
