I have an Alienware M18 R1 AMD with a 7945HX cpu that does not complete the boot process when on battery power AND the battery is below about 70%. If the battery is almost full, it boots fine. This is repeatable using the live usb of every distro I have tried (Fedora, Ubuntu, Arch). I have updated the machine to the latest BIOS 1.2.2. Using a separate disk, I can install and boot into windows 11 without issue. If I run with acpi=off kernel parameter it will boot but many devices do not work. I have tried many different kernel parameters to try and fix the issue without success. As far as the hardware I have tried: - different hard drives - disabling hybrid graphics in BIOS - replacing the battery - disabling as many devices as I can in the BIOS (wifi, NIC, etc) When I try to boot with battery < 70%, it gets part way through the booting process and then turns off or reboots. The logs do not get flushed to disk so I can't for sure tell what the last log entry is. I have used my phone to try and record the output to the screen before it shuts down but the last entries I can see don't look suspicious. One other issue that may be related is that after boot, a process is hammering the kernel with system calls, pegging one core to 100%. I have to run: echo 'on' > '/sys/bus/usb/devices/usb1/power/control' To stop it. I suspect the BIOS has some issues but I do not know how to debug it. Any tips on what to try would be appreciated. Below are interesting snippets from my dmesg log of a successful boot while on AC power.

I have mostly been using Fedora 38 but I've reproduced it with these live USBs as well: - Ubuntu 22.04 - Ubuntu 23.04 - Archlinux 2023.06.01 - Fedora 38 - Fedora Rawhide 2023.06.05 Always the same behavior--it shuts down or reboots part way through the boot process.
You can try CONFIG_PSTORE_RAM option in kernel configuration. It helps you in collecting last boot logs after a soft reboot. You can retrieve logs from /sys/fs/pstore/
