Ar galiu naudoti užduočių planavimo priemonę, kad galėčiau stebėti kompiuterio bateriją?

I need to create a task in Task Scheduler based on battery level changes. For example, say my laptop’s battery drops from 67 percent to 66 percent charge remaining. How can I run a task based on this event? Does Windows log this at all? I was unable to find information on this anywhere.

I Need to Create a Task in Task Scheduler Based on Battery Level Changes

Windows does not log this kind of information/details as events. You can, however, use something like the batch file below and create a custom event.

Battery.cmd

This batch file monitors the current battery percentage charge and creates a user defined event if the charge drops below a user defined threshold value.

• The eventcreate command works on Windows XP up to and including Windows 10. It requires administrator privileges to work.
• Set _threshold as required.
• If the battery falls below this value, an event with ID 999 will be generated in the APPLICATION event log with the description “Battery charge has dropped”.
• Modify the eventcreate command as required for your situation.
• Modify the timeout delay as required for your situation.

Example Output

My battery currently has a charge of 81 percent. I set the threshold to 82 percent. Here is what happens when I run Battery.cmd:
