Hardware • Nvidia GPU: Unable to change power state from D3cold to D0, device inaccessible

Hello,

I am not sure what you mean by that. There is a battery reset pinhole at the back. Is that what you mean?

My guess is that your internal Nvidia card is in a low-power state from which the kernel is unable to wake it up.

The first thing to understand is why it is in this state:

1. The most common explanation is that it was put into this state after Windows was partially shut down or suspended to ram or hibernated to disk. However, you have reported that this is not the case, although it is suspected that an interaction with Windows could indeed be the case.
2. The other explanation is that the computer's BIOS has put it in this state for some reason. In this case, you should be able to configure the BIOS to check that it is not disabled at BIOS level.

In case 1), you could double check that you have forced a hardware shutdown after the software shutdown. The hardware shutdown (which should reset the computer's peripherals to their reset state) can be done by disconnecting the computer from the main power supply and, for notebooks, disconnecting the battery for a sufficient period of time after disconnecting the computer from the main power supply .

Modern notebooks are not always designed to allow normal users to disconnect the battery, so I asked you.

According to the Acer website [1], Acer seems to have taken this situation into account with this "battery pinhole reset" (I was not aware of such a solution):

This procedure will temporarily disconnect and then reconnect the internal battery.

In any case, it's an invasive measure and I don't know about side effects (i.e. on Windows).

So the decision and risk assessment is up to you.

Hope this helps.
