Fixing Battery Not Charging on Dell Laptop After Sleep Mode
## Direct Answer
To fix a Dell laptop battery that won’t charge after sleep mode, try restarting your laptop, checking the power settings, and updating your BIOS. If these steps don’t work, you may need to reset the battery gauge or contact Dell support.
## Step-by-Step Guide
1. **Restart your laptop**: Sometimes, a simple reboot can resolve the issue. Turn off your laptop, wait for 30 seconds, and then turn it back on.
2. **Check power settings**: Ensure that your power settings are not set to “balanced” or “power saver,” as these modes can prevent the battery from charging. Go to **Settings** > **Power & sleep** > **Additional power settings** and select the “High performance” plan.
3. **Update BIOS**: Outdated BIOS can cause battery charging issues. Visit the Dell website, download the latest BIOS update for your laptop model, and follow the installation instructions.
4. **Reset battery gauge**: If your laptop’s battery gauge is not calibrated, it may not charge properly. Unplug the power cord, turn off your laptop, and let the battery drain to 0%. Then, plug in the power cord and charge the battery to 100%.
5. **Disable and re-enable the battery driver**: Go to **Device Manager** > **Batteries**, right-click on **Microsoft ACPI-Compliant Control Method Battery**, and select **Disable device**. Wait for 10 seconds and then enable it again.
