I am having issues with my laptop. It dies if I let it sit idle for more than a few minutes. It stalls during booting up with a black screen and the caps lock button lit but nothing else, no mouse cursor, no activity from any attempt to get it going. Only thing to do is power it off by holding down the power button until it shuts off.
It is a Dell Inspiron 16 2-in-1 purchased in Feb 2024 running Pop!_OS 22.04 LTS. No other OS installed, I overwrote the Windows OS when I installed Pop!_OS. It was running fine until it started giving firmware update messages, but the firmware (Dell System Firmware 1.19.0) fails to install when I hit the update button. Instead it comes back with "error in fwupd client: calling Install method failed: failed to set /sys/firmware/efi/efivars/fwupd-c5e1348e-99ce-4861-9cab-b98919ce9d28-0-0abba7dc-e516-4167-bbf5-4d9dlc739416 as mutable: failed to open: No such file or directory.
Any help would be appreciated.
