Hello guys I have an MSI GT72VR and I often see this error in the windows event log on boot: Error 3/6/2021 9:41:43 AM ACPI 13 None The embedded controller (EC) did not respond within the specified timeout period. This may indicate that there is an error in the EC hardware or firmware or that the BIOS is accessing the EC incorrectly. You should check with your computer manufacturer for an upgraded BIOS. In some situations, this error may cause the computer to function incorrectly. When I get this error it seems to coincide with either the bluetooth(before i replaced the module) or wifi not being recognized. I've replaced the killer wireless module with an Intel® Wi-Fi 6E AX210 chip which the Bluetooth works much better on. When this error occurs if I run the ec firmware updated the system will boot up and BT and Wifi are recognized and work again. But after sometime there can be issues. I have the latest bios E1785IMS.119 and ec firmware 1785EMS1.107. My guess is the motherboard needs to be replaced. I think its always been this way though since buying it over 4 years ago.
