I'm using a Lenovo Laptop, Windows 10.

Update 15/2/2023: just today I upgrade to Windows 11, the same problem still persists (!)

Recently I think the battery cell is not fully functioning, and system occasionally triggers the Event 524, Critical Battery Trigger Met and subsequently, the Event 42,The system is entering sleep., even though the laptop is connected to the power source AND the battery is more than 95% charged.

Obviously, the system is misreporting the battery condition, and hence resulted in the above trigger, and then subsequently, the sleep event. This is very annoying because it disrupts the rhythm of my work.

How to stop the system from entering the sleep mode if the Event 524, Critical Battery Trigger Met is (mis)reported, and despite (potential) battery fault?

Some asked: how do you know that this is a misreporting, and not because the battery is really dying? My answer:

  1. It's simple. Right before the machine goes to sleep, the battery is still more than 95% charged.
  2. Does that really matter if the battery is dying? I am connecting the laptop to a power supply. So even if the battery dies the laptop should still have power supply, right?

Maybe this can help. Press Windows key and type: Edit power plan In this menu go to: Change advanced power settings In the next menu, all the way at the bottom there is Battery. In here you can define the Critical Battery Action for plugged in, for you this could be: do nothing.

Hope this helps.

Running the following command as admin will set the Critical Battery Action for On battery to Do nothing. After setting this programmatically the Do nothing option should be available in the GUI dropdown for Plugged in.

powercfg -setdcvalueindex SCHEME_CURRENT SUB_BATTERY BATACTIONCRIT 0

So, I think I found the solution for this. My computer kept doing this at 86% charge and mine had to do with a setting on the power plan. When I went to the "Edit Power Plan" Menu, then navigated to "Advanced Power Settings", then "Battery" I found that the Critical Battery Level had been set to 86%. This means that my computer would shut down when the battery went below that. All I did at this point was to restore defaults for the plan and it adjusted to 5%. However, if you have other custom settings for the power plan that you would not like to lose, then you can adjust the critical battery level setting manually to whatever percentage you like. The solution to the annoying problem was so straightforward that I made an account just to share this.

Adjust Critical Level to 5%

For me the issue occurred when I changed my power mode settings(System > Power & Battery) to 'Best Performance' in Windows 11 installed on the laptop. My system has a gpu and two fans running all the time. I never faced this issue when my power mode settings is set to 'Best Power Efficiency'. My laptop doesn't even sleeps even when I remove the charger as it still has battery left but occasionally shuts down with same 'Critical Battery Trigger Met' when set on performance mode.

Edit: Critical battery level is set at 2%.
