Battery status discharging8/10/2023 ![]() If we find out that the issue is not solved on all machines, I would leave the workaround for now as it is and let the developer know about it - although I do not expect that I just use all means of verification if they are available anyway. There is no problem with waiting for the release within Fedora. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h 25 A. Only do this if you are sure to know what you are doing! In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. If there are any issues, return to the last kernel. It is recommended to avoid full cycles and stay between 100 and 50 DoD (. Replace with your architecture! You can find out with uname -r → the last part (after the last “.”) of the output is your architecture. A partial charge and discharge will therefore reduce stress and prolong battery life. If you are aware of the risk, and still want to check it out, you can do so by dnf update & reboot. ![]() So integrating this kernel into Fedora has just started - and you have to be aware that unintended behavior cannot be excluded at the moment. For details, see Interaction of Battery Status and Notification Routines.Well, theoretically yes, but be aware that the 5.19.9 kernel is not even in the testing repository yet. The class driver's Batter圜lassStatusNotify routine and the miniclass driver's BatteryMiniQueryStatus, BatteryMiniSetStatusNotify, and BatteryMiniDisableStatusNotify routines are used in sequence by the two drivers to provide timely status information. For more information, see System Power Policy. Typically, the system attempts to enter a sleeping state or powers off the computer. The details of the power policy vary from system to system, depending on hardware capabilities, application settings, and user preferences. If the battery supplies system power or is a secondary (rechargeable) cell, the system carries out the DC power policy for a critical battery. ![]() When the miniclass driver reports a critically low, discharging battery, the power manager assumes that battery failure is imminent. Such remedies might include switching to AC power or to another battery, if the miniclass driver can do so. The miniclass driver should not report a critically low, discharging battery (BATTERY_CRITICAL and BATTERY_DISCHARGING) until it has ascertained that the condition is not merely a transitory fluctuation and has exhausted all other means of remedying the situation. The miniclass driver also reports one or more of the following constants that describe the battery's power condition: In the buffered BATTERY_STATUS structure, the miniclass driver reports the battery's voltage, capacity, and charge/discharge rate to the extent that the miniclass driver can determine them. The BatteryTag parameter is a value previously returned by BatteryMiniQueryTag. The Context parameter is a pointer to the context area that is allocated by the miniclass driver and passed to the class driver in the BATTERY_MINIPORT_INFO structure at device initialization. The following is the prototype for this routine: typedef The battery class driver calls the miniclass driver's BatteryMiniQueryStatus routine to get the power state, capacity, voltage, and discharge rate of a battery.
