when I closed the lid of my computer. windows 10 battery/ sleep and power management tool would not allow me to change from hibernation to sleep. To fix this

– On the Desktop, right-click on This PC and select Properties

– On the left, choose Device Manager

– Click the arrow next to Display Adapters to expand that category

– Right-click on Intel(R) HD Graphics Family and select Update Driver Software…

– Choose the option to Search Automatically for Updated Driver Software

– Your computer should find and automatically install the updated driver

– After the installation is complete, restart your computer

This resolve the computer sleep problem. them I flash as recommended by patrick1234578
the same case. I made it finally.
version is 9acn32ww

There may even be a possibility to create a script that will automatically do this. Whatever the model is....

Code:
UEFIFind imagefile {header | body | all} {list | count} pattern
UEFIExtract imagefile GUID_1 ... [ -o FILE_1 ... ] [ -m MODE_1 ... ] [ -t TYPE_1 ... ]
But I don't have time to deal with that.

Each bios have a different implementation, a script is not enough to get all the job done.

I was thinking of Lenovo models where the insyde BIOS all have string of “Unauthorized Wireless network card is plugged in” and also 74 to EB to be modified..

Thanks for the Donovoan link.

A few days ago a new board for the g50-70 arrived at my place from ebay. There was no Mac Address, UUID, serial, Computer Model ... in the Bios.

"9acn28ww" installed ...i downgrade it to version 9ACN26WW - then used same sleep bug to clone my old motheboard - backup of bios.bin

Now i have two laptops with cloned bios - with identical serial, UUID... macOS works perfectly on both.

Otherwise I have a couple of bios chips in reserve if i bricked Bios - i know to solder them nicely....

Sleep bug only works for Bios version 9ACN26WW.

Also You need to have a video driver installed from here

Otherwise you cannot go to sleep mode.
When you go to sleep mode, wait for the left led to start blink.
After 20 seconds get out of sleep - and then enter cmd as admin.
