If you open mate-system-monitor and go to the "processes" tab, you can see if mate-system-monitor is still running or not. If mte-power-manager does not show up in this list of processes, it has crashed, or maybe frozen.

Try running killall -9 mate-power-manager first, then mate-power-manager and if this does not bring back the battery icon, please post whatever text you get in the terminal window from the second command

Hello,

here are the messages after mate-power-manager

(mate-power-manager:3469): PowerManager-WARNING **: 18:23:52.231: Failed to get session for pid 3469: The name org.freedesktop.ConsoleKit was not provided by any .service files

(mate-power-manager:3469): PowerManager-WARNING **: 18:23:52.236: could not map keysym 1008ffa8 to keycode

Neither of those should cause a delayed crash. Does it keep running in terminal, or does it exit?

As long as the terminal remains open, the battery symbol will be visible. If the terminal is closed, it disappears.

It seems to be a problem where the hardware (of the battery?) could play a role, or there are two problems.

I noticed today that the battery symbol did not disappear, but the charge level did not change for a long time and the battery LED on the notebook began to flash (which remains so even after a shutdown). Also acpi -V showed the wrong charge level.
With killall -9 mate-power-manager I ended the battery display and then ran mate-power-manager. The error message then also appeared.

~$ mate-power-manager

(mate-power-manager:5036): PowerManager-WARNING **: 20:20:53.960: Failed to get session for pid 5036: The name org.freedesktop.ConsoleKit was not provided by any .service files

Wen running mate-power-manager from terminal, for the icon to disappear when the terminal i closed is the expected behavior, as closing the terminal also closes processes started from it that are holding the prompt.

If you run mate-power-manager & that will send the process to the background and let you keep the icon showing. If it disappears after a while again, restarted without the& keep the terminal window open, and post whatever text shows up when the icon disappears

If this is being caused by a hardware issue, that could mean nobody without the same hardware problem can duplicate it. Seems to me there is almost always something on a laptop whose makers only support Windows that doesn't work right or doesn't work at all in Linux. I've had two HP laptops in a row where the touchpad isn't detected at all so a separate mouse is required.

Maybe it is a hardware issue. With dmesg I could find this:
