Hi Rayyan,

When the estimated remaining battery charge drops down to approximately 40%, give or take 5%, the laptop abruptly turns off. it's the equivalent of a hard reset. when I restart the machine it doesn't get past post before shutting off again so obviously the battery is completely drained.
Therefore follow below steps.
  1. Go to Control Panel > System, then select ‘Device Manager’ from the left pane.
  2. Expand the ‘Batteries’ section. A list of devices will appear. Look for the ‘Microsoft ACPI Compliant Control Method Battery’.
  3. Right-click on the device, and select ‘Uninstall’. Windows will prompt you to confirm the device's uninstallation. Click ‘OK’ to uninstall the driver.
  4. After the uninstallation is complete, reboot your computer as soon as possible (Windows will automatically detect and reinstall the drivers upon reboot).
  5. Power off your laptop and allow it to charge at least 8 hours or until it is fully charged, while it is powered off (not sleeping/hibernating).
  6. Unplug its power adapter, then power on your laptop and use your laptop battery until it depletes its battery.
  7. Fully charge your laptop again in order to recalibrate the charging sensor.
I hope this helps.

Regards,
Lokesh
