Before opening your Lenovo, first make sure that your device is completely powered off and that your charging cable is disconnected. Make sure there is no electricity actively flowing through the device before servicing it.

Before breaking into your computer here are a few things you can try to get your computer started.

When running large numbers of applications, it causes certain functions such as the CPU or GPU in the device to run at a higher level, often resulting in excessive heat output. Try decreasing the number of tabs you have open at any given moment.

When issues arise with computer hibernation and shutdown, it results in the device running for prolonged periods of time. This can lead to restart or permanent damage to the device. Try resetting the settings you have on your device for the computer hibernation or shutdown.

Look to see what power plan your device is running on in the control panel > power options. If it running on high/maximum performance try switching to "balanced".

You may need to check if your device is running on the newest windows update. Is your system running on the correct BIOS, drivers, and the operating system.

If none of these tips help address the issue, try following the troubleshooting steps below to diagnose the problem with your device.

The harder your Lenovo ThinkPad is working, the more heat it generates and the fan should compensate accordingly. However there are a few things that could result in fan failure. First, observe the condition of the fan. Check for dirt or debris that could be degrading the functional quality of the fan. Use canned air or a small brush to clean, if necessary. Next, look for any visible damage to the fan, connectors, or wires. If there is any noticeable damage or the wires connecting it to the system board appear broken, replacement parts may be necessary.

If temperatures remain high regardless of application or work load, it may be due to blocked vents or dust inside the device. First, observe the fan and possible vents. If there is any dust or other debris apparent you can try using compressed air or a pair of fine point tweezers to remove it through vents. You may need to remove the back of the laptop to better clear dust from vents and fan.

If the fan and vents appear to be in good condition, the problem could be the heat sink. This option requires a bit of removal as the observable symptoms are covered. At the back of the fan, where the heat sink connects, there are large vents that often trap dust. Dust can be removed with a small brush, compressed air, or a pair of tweezers. Thermal paste, found under the heat sink, may be low and could need replacement. (Thermal paste is used for its more efficient heat transfer and distribution of heat through removal of air pockets).
