the battery level is 0 % with "?" in battery symbol.

this is not a bug, you device doesn't have a battery, of course it will said "?"

Check the Documentation on how to spoof the battery https://docs.blissos.org/configuration/configuration-through-command-line-parameters/#battery-stats

off course ? No. With android-x86 (android 8.1) there is no problem. The battery symbol indicates that the device is charging and level is 100 % without doing any settings.

Please I get a little knowledge about Bliss, grub, menu entry, kernel command.

There is no more menu.lst in grub folder. In what command line to add "SET_FAKE_BATTERY_LEVEL" ?

Thanks

No. With android-x86 (android 8.1) there is no problem.

That is Android 8.1, this is Android 13, things changed

There is no more menu.lst in grub folder. In what command line to add "SET_FAKE_BATTERY_LEVEL" ?

Press E on the entry, edit it and use Ctrl+X to boot

Press E on the entry, edit it and use Ctrl+X to boot

It is not permanent.

The doc says we must modify android.cfg but look in the contents. A non-techie person does not understand where to add "SET_FAKE_BATTERY_LEVEL=100". The doc is for a developer.

Thanks

you came here to ask us where is grub.lst and now we give you the configuration file you are whining that this is not for "non-techie" person ???

Yes I know about grub just where to find menu.lst and how to find a menu entry and to modify the kernel command. Also for the kernel command I just know I can add "video=1280x800x32" and that's all. Many times I don't understand the meaning of the parameters I add. I just follow the advice found in internet in a doc or something else.

For each particular problem I encountered, I learned just the little knowledge to fix the problem.

I can fix only the problems I encountered.

I know nothing about Bliss and the other grub config files and how to modify them.

You are not the first which assumes I am a specialist of grub or something else, but I am not.

In android.cfg, in grub.cfg, I am lost. In the previous version of Bliss there were a menu.lst which disappeared.

Thanks
