Laptop shuts off when pressing D, G, and F keys
So my brother has an HP x360 chromebook, and he recently tried using it (we don’t use it often) and he recently asked me to use my keyboard to use the laptop. I asked why and he said because the D, G, and F keys shut off the laptop.
He said he was unsure of which keys it actually was, but he showed me a bit ago that it did turn off the laptop.
He says it might be a battery problem, which I think is possible, but how do the keys turn off the laptop in the first place ?
I’m just confused on how it’s happening.
