Solution 2 to fix Dell Laptop fan if not starting or Working


Here are some common causes of fans not working, abnormal, or loud fan noises, and overheating:

  • A fan or air vent that is obstructed
  • Accumulation of dust on vents or fans
  • There is not enough ventilation
  • Physical damage
  • Out-of-date BIOS and device drivers


Check and clean air vents

If air vents are blocked, the processor, memory (RAM), and other hardware may overheat, causing serious performance issues, which may then lead to hardware failure. Additionally, excessive heat can decrease performance as most processors automatically reduce speed to compensate for heat-related issues. The computer fan may be running constantly and making an abnormal or loud noise if the computer is not running as efficiently as possible or if the air vents are clogged.

Make sure that your computer has adequate ventilation to prevent dust from accumulating. Dust and lint accumulate on cooling fins, preventing air from flowing around them and making the fan work harder.

There may be several fans inside your Dell computer to keep the internal components cool:

  • Desktop computers are equipped with more than one fan – one for the processor, one for the GPU, one for the power supply (PSU), and one or more for the chassis (case).
  • It is also possible for laptop computers to have more than one fan, which varies from model to model.

Provide proper ventilation

It is important for computers to have adequate ventilation both outside and inside, so that air can circulate more easily. In addition to increasing the life of computer fans, adequate ventilation can also help them perform more efficiently. If you want to prevent the computer from overheating, you can also place it in a cooler room in your house or office.

Guidelines to ensure adequate ventilation

  1. Desktop computer – Put the desktop upright on a flat, hard surface. Provide sufficient clearance in front of and behind the computer (if your computer has air vents on the bottom or side, ensure there is clearance on all sides).
  2. Laptop computer – It is best to place the laptop on a flat, hard surface with the bottom and side air vents not obstructed.

Run a hardware diagnostic test

By running a hardware diagnostic test, you can identify hardware-related issues and determine what troubleshooting steps you need to take to resolve them. In order to determine if your Dell computer has a hardware problem, it is recommended that you run a hardware diagnostic test. The company offers both an integrated diagnostic tool as well as an online diagnostic tool. Check if the hardware devices are working properly using Dell SupportAssist or ePSA.

Running the Dell Pre-boot System Assessment or enhanced Preboot System Assessment (Dell PSA or ePSA)
  1. You should restart your Dell computer.
  2. Upon seeing the Dell logo, press F12 to enter the One-time Boot Menu.
  3. Using the arrow keys, select Diagnostics and press Enter.
  4. To complete the diagnostics, follow the on-screen instructions and respond appropriately.
    Be sure to record the validation code and the error code if the test fails.

Update the BIOS and device drivers

Dell recommends updating your device drivers and BIOS as part of your scheduled update cycle. Updated device drivers and BIOS may contain feature enhancements and changes that help keep your system software current and compatible with other computer modules (hardware and software).

In order to ensure optimal performance of your computer’s fans, you should install the following device drivers.

  • BIOS
  • Chipset driver
  • Thermal chipset driver
  • Video card (GPU) driver

To learn how to download and install a device driver on your Dell computer, see the Dell knowledge base article Drivers and Downloads FAQs.
