My laptop motherboard model is DAXW2 EMBABE0 REV: B. Upon booting, there's a red "Warning:ThisBIOSis Not for Production Use." message in the upper left corner. I once upgraded the motherboard ME (Management Engine), and afterward, the touchscreen stopped working. Later, the wired network adapter also failed.

Serial Number: 5CD9012GNF

SKU#: XW2SKU2#ABA

Is there any way to fix this? I've attached the BIOS information read using a programmer after removing the chip....
