Why does my laptop freeze only when I use battery power?

My laptop freezes unexpectedly only when I am running on battery power, while it works fine when plugged in. The issue occurs randomly during normal use and forces me to restart the device, but it never happens when connected to AC power.

    This is the most important starting point. Make sure your Windows is fully updated. Then, go to your laptop manufacturer's support website (e.g., Dell, HP, Lenovo) and manually check for and install any available updates for the BIOS and chipset drivers. Outdated firmware is a very common cause of this specific problem .

  • Please try these steps to restore power plans to defaults, see if it helps:

    5. Then go to Change advanced power settings.
