If Your LG Laptop Battery Is Not Charging

Troubleshooting Laptops 08/18/2026

<div class="content-service-view" itemtype="HowTo">
     <p class="description info-desc">If your laptop battery is not charging, check the power adapter connection and its power output. The battery may stop charging at 80% if the Extend Battery Life feature is turned on. It may also fail to charge if the battery has reached the end of its lifespan.</p>

<h2 class="tit mainName">Why Isn't Your Laptop Battery Charging?</h2>

<li>Your power adapter or cable is not securely connected.</li>

<li>Your adapter's power output does not meet your laptop's requirements.</li>

<li>Your battery has reached the end of its lifespan.</li>

<li>The Extend Battery Life feature is turned on, limiting the charge to 80%.</li>

<li>Your laptop is using more power than the USB-C adapter can supply.</li>

<li>Your battery temperature is too low, which slows down charging.</li>
      </ul>

<h2 class="tit">How to Restore Battery Charging</h2>

<h3 class="name">Step 1. Check Your Power Adapter Rating</h3>

<div class="text">
         <p>
            Check the rating label on your power adapter and the product label on the bottom of your laptop to ensure the voltage and current match.<br/>
            Use an adapter that provides the required power output. For example, using a 40W adapter with a laptop that requires a 60W or 90W adapter may prevent your battery from charging correctly or cause your screen to flicker.

      </div>

<h3 class="name">Step 2. Check Your Power Adapter and Cable Connections</h3>

<div class="text">
         <p>
            Make sure your power plug is securely connected to the wall outlet.<br/>
            Make sure your power cable is securely connected to the adapter.<br/>
            Make sure your adapter connector is securely connected to your laptop.<br/>
            Check the charging indicator on your laptop once everything is connected.
          </p>        </div>
      </div>

<h3 class="name">Step 3. Check Your Charging Indicator</h3>

<div class="text">
         <p>On some models that support USB-C charging, your charging indicator shows the current charging status.</p>

<li>On: Your AC adapter is connected, and charging is complete.</li>

<li>Blinking: Your AC adapter is connected, and your battery is charging.</li>

<li>Off: Your AC adapter is not connected.</li>
          </ul>
         <p>
            If your laptop turns off after displaying a low battery warning and the power status indicator blinks three times when you press the power button, connect your AC adapter.<br/>
            Allow your battery to charge before turning on your laptop again.

      </div>

<h3 class="name">Step 4. Turn Off Extend Battery Life</h3>

<div class="text">
         <p>
            When the Extend Battery Life feature is turned on, your battery stops charging at 80% to help reduce battery aging<br/>
            You can check and change this setting in the LG app installed on your laptop.
          </p>

<li>
              <strong>my gram</strong><br/>
              Open my gram, select PC Maintenance, then Power &amp; Performance, and then Extend Battery Life.
            </li>

<li>
              <strong>LG Smart Assistant</strong><br/>
              Open LG Smart Assistant, select Power Setting, and then Extend Battery Life.
            </li>

<li>
              <strong>LG Control Center</strong><br/>
              Open LG Control Center, select Power Management Setting, and then Extend Battery Life.
            </li>
          </ul>

<h3 class="name">Step 5. Reduce Power Use During USB-C Charging</h3>

<div class="text">
         <p>
            If your laptop supports USB-C PD charging, your battery may continue to discharge while connected if your laptop uses more power than your adapter supplies.<br/>
            This can happen when you have several external devices connected or multiple power-intensive apps running.<br/>
            Make sure your adapter provides the power required by your laptop.<br/>
            Disconnect any external devices you are not using and close unnecessary power-intensive apps.<br/>
            Check whether your battery begins charging normally.

<h3 class="name">Step 6. Resolve Charging Issues in Cold Environments</h3>

<div class="text">
         <p>
            Charging may slow down to protect the battery cells when your battery temperature falls below 10°C (50°F).<br/>
            The displayed battery level may also be temporarily inaccurate in a cold environment.<br/>
            Move your laptop to a warmer environment above 10°C (50°F) and check whether your battery charges normally.<br/>
            Charging and discharging your battery two or three times in this warmer environment may help restore an accurate battery level reading.

<span aria-label="Answer" role="img">A.</span> If your laptop turns off immediately after you disconnect your power adapter, your battery may not be supplying power correctly.
