How to disable sleep mode so that i can just switch the device on once and then forget about it?
It depends on the exact model of device being used by you and the version of software being used.
However, the automatic wireless shutdown configurations are usually available in advanced configurations which can be used to disable automatic wireless shutdown.

Unable to start the virtual device.
VirtualBox cannot start the virtual device.
Virtualization technology (VT-X, SVM, AMD-V) may be unavailable or disabled. Please verify your BIOS/UEFI settings.If it is available and enabled, please verify that no other hypervisor (QEMU) is currently in use.
I'm unable to launch the device.
When I try to run android emulator I got following error and my emulator doesn't start at all.
Error:
Please check if you can update your video driver.
If it doesn't help, try to Edit the AVD and set "hw.gpu.mode=off".
When I set hw.gpu.mode=off then emulator starts but it super extremely slow even if I add 4GB of ram. I think it's due to hw.gpu.mode=off. Is there any other workaround still to use gpu?
Componenets which are enabled:
Hyper-V
Virtual Machine platform
Windows Hypervisor Platform
Virtualization enabled in BIOS
Besides I've tried different fixes available on internet like : disabling enabling Hyper-V & Windows Hypervisor platform including system restarts etc but none seems to work yet.
In my application, I am using STm32L4R5VG as a host MCU. I want to upgrade the firmware of host MCU in run time over USB through the Android mobile app.
I have looked into USB DFU mode, but in that case, my device will enumerate as ST USB and also I need to enable the boot loader with boot pin.
In actuality, my device will connect with the Android mobile app using the CDC class device and enumerates as VCP. So I want to send the firmware file from Android mobile to host MCU over VCP and write into Bank2 of internal flash (as current code is in Bank1). Once the file transfer is done, the device will reboot on its own and check for the latest firmware and boots from Bank2.
I am stuck at how to write at bank2 securely during run time and perform self reset to boot from Bank2.
If anyone already worked on this or know about this then please guide me or point to the link where I can get details for this.
On my BIOS i have option for Virtualization, but even after enabling it am not able to install HAXM. I tried unchecking hyper-V.
All my attempts failed in installing HAXM. Please suggest some solution.
Please confirm if your OS is indeed sensing that virtualization is enabled.
Download the Intel Processor Identification Utility for windows.
Check it out here -> Intel tool
Once it is installed go to, CPU technologies tab and below you will see Intel Virtulization Technology and opposite to that you will see either a Yes or No.
There is a tool available from Microsoft also.
Check it here ->
Microsoft tool
If it's a no, you may wanna check bios settings again for enabling virtualization option and then try checking the status again.
If it's a Yes then try installing Intel HAXM. If it's still No, maybe your OS is having some problem.
How does keyboard and other I/O devices work before booting of OS.For example: when i have to choose which OS to boot at grub menu?
Because basic devices like the keyboard can be controlled by the BIOS.
Before the Operating System is loaded the BIOS is in-charge of controlling the the i/o devices.
