I get these errors sometimes (not always) when powering off my hp laptop. The caps lock also starts blinking (which most likely means “CPU failure”) and the screen gets stuck here. And then I have to hold down the power button for it to force poweroff. I dont notice any major issues when using the laptop, but this is terrifying and may cause problems in the future. Please help.
Blinking caps lock LED indicates a kernel panic, so it’s most probably a kernel panic, not the CPU.
That being said, a kernel panic usually isn’t “silent” like this one seems to be. Do you have any 2nd monitor hooked up? Maybe the kernel panic is outputted there rather than on your main screen.
