Introdução

The Lenovo ThinkPad E14 Gen 4 is a 14-inch business laptop available with either 12th Gen Intel Core or AMD Ryzen 5000 Series processors, mainly marketed for professional use. Key features include fast storage up to a Gen 4 SSD, Wi-Fi 6, and a range of ports including USB-C.

Use this guide when you need to clean or replace the fan and/or heat sink or to replenish the thermal paste in your device. Make sure your device is not connected to any form of electricity when opening to do any repairs.

If you need to apply thermal paste, you should check out this comprehensive guide.

Warning: Thermal paste is responsible for conducting heat from the processor to the heat sink. Reassembling a computer without applying thermal paste will cause the processor to overheat, resulting in permanent damage.

    • Insert an opening pick into the seam near the hinges.

    • Working from the hinges to the front, gently pry apart the back of the device from the main body.

    • You should hear little pops and see a small gap forming at the seam before attempting to remove.

    • Plastic pry tools are the best to use with electronics such as phones, tablets, and laptops because they are designed to break before the device does.

    • Carefully lift the loosened panel away from the laptop.

    • Before attempting to lift the panel off, make sure it has been pried away from all edges and corners of the device. Trying to remove the back panel when any part is still firmly attached to the laptop can cause damage to the device.

    • The thermal paste may need to be replaced before you put things back together. Look for the spot the heatsink was previously attached; if the surface seems dried out, that will need to be removed.

    • Make sure you remove all of the old thermal paste before applying new paste.
