Lenovo IdeaPad 1-15ALC7 Overheating

The laptop generates heat while running applications. If too many programs are open at once, the cooling system may struggle to keep up, causing excessive heat buildup.

1. Open Task Manager by pressing CTRL + SHIFT + ESC simultaneously.
2. Look for applications consuming the most CPU power (percentage displayed under the "Processes" tab).
3. Identify any resource-heavy programs that may be contributing to overheating.

1. Select the application using excessive CPU power.
2. Click "End Task" to close it.
3. Monitor the laptop’s temperature and performance to see if the issue improves.

A buildup of dust and debris in the vents can restrict airflow, preventing the cooling system from functioning properly. Poor airflow leads to overheating.

1. Turn off the laptop and unplug it from power.
2. Flip the laptop over and remove the screws securing the bottom panel.
3. Locate the heat sink grills and exhaust vents.
4. Check for visible dust, lint, or other debris blocking airflow.

1. Use a soft brush (such as a toothbrush) to gently remove dust from the heat sink grills.
2. Inspect the fan blades for accumulated debris.
3. Carefully clean the fan using a compressed air can or soft brush.
4. Reassemble the laptop and test whether the overheating issue improves.

Tip: You may need to clean the cooling system multiple times over the laptop's lifespan to prevent overheating from recurring.

If the laptop is overheating, the internal cooling fan may not be functioning properly. A non-working or underperforming fan prevents heat from dissipating effectively.

1. Listen for the fan while the laptop is on and running multiple applications. If it’s silent, the fan may not be turning on.
2. Flip the laptop over and locate the exhaust vents.
   • Place your hand near the vents—if no warm air is being expelled, the fan may not be working.
3. Open the laptop and visually inspect the fan.
   • If it’s barely spinning or not spinning at all, it’s not cooling the laptop effectively.

1. Open the Lenovo Vantage App (pre-installed on Lenovo devices).
2. Navigate to Hardware Settings > Thermal Mode.
3. Set cooling to Maximum Performance and observe whether the fan speeds up.
4. Run a Fan Diagnostics Test in Lenovo Vantage to check for fan errors.

1. Open the laptop and locate the fan.
2. Check if the fan is misaligned, damaged, or obstructed.
3. If the fan is physically damaged or not spinning despite adjusting the settings, a replacement may be necessary.

If the fan remains unresponsive after testing and troubleshooting, it may be defective. Follow our Fan Replacement Guide to install a new fan and restore proper cooling.

If the fan isn't spinning, it may not be receiving power due to a loose or damaged connection.

1. Open the Lenovo Vantage App and run a Fan Test to verify if the fan is operational.
2. If the fan does not respond, remove the bottom panel of the laptop.
3. Locate the fan and check if its cable is securely plugged into the motherboard.
4. If the connection appears loose, gently push the connector into place.

If the fan cable is damaged or disconnected and cannot be reattached, replacing the fan may be the best solution. Follow our Fan Replacement Guide to install a new fan.
