Could you give hwinfo output? I guess you can still run it on the changing state.

Here it is: https://pastebin.com/adHnH2rR It's from a latest Leap 15.2 Beta Live ISO. If it has to be from my Tumbleweed installation, then I will provide it, if needed. -- You are receiving this mail because: You are on the CC list for the bug.

Thanks.

And do you see the similar effect on the already installed system? e.g. the system doesn't boot up when booted without power cable? Or if you unplug the power cable, does the system still run well?

If it's only about installer, it's a bit difficult to catch what's going there...

I think, I only see this on an already installed system, but I haven't really checked if it also happens on a LiveISO. The output of the LiveISO system above is from a system with connected charger. I will test this and report back. -- You are receiving this mail because: You are on the CC list for the bug.

Aha, it wasn't clear from the description that you've faced the problem on the "installed" system. I thought you're hitting at "installing", but it was my misunderstanding, then.

Now the question is whether it comes from the kernel package or something else. To identify that, could you try to install Leap 15.2 kernel onto your TW system? Just grab kernel-default-5.3*.rpm from http://download.opensuse.org/distribution/leap/15.2/repo/oss/x86_64/

then install it like zypper in --oldpackage kernel-default-5.3*.rpm

then boot with it. If you can reproduce the problem with this kernel and the issue doesn't appear with Leap 15.2 system, it's something else than kernel package.

I have installed the OS from the latest Tumbleweed snapshot and booting the system without a charger works well. It works on both kernel-default-5.3.18-lp152.10.4.x86_64 and on the (currently) latest kernel-default-5.6.4-1.2.x86_64. I will keep this bug report open for a few days, will make further tests and report back. Thank You. -- You are receiving this mail because: You are on the CC list for the bug.
