Friends, in today’s blog post, we will learn How to Run Diagnostic Test on Dell Laptop, if there is any technical problem in a Dell laptop and how to know what technical problem is with which internal hardware.
Dell is also an emerging trusted brand among laptop manufacturers in India. The number of users of Dell laptops in India is enormous. In such a situation, we all need to know about the technical problems occurring in Dell laptops. Dell laptops have a pre-installed tool called Diagnostic Tool to check for technical issues. Let’s understand how to run this tool on your Dell laptop and how to fix some common hardware problems.
Manufacturer Dell has given its customers a pre-installed laptop called Dell Diagnostic Tool to find out about the technical problems in the laptop. By running, it can detect technical issues in Dell laptops.
You will need a keyboard to run a diagnostic test on a Dell laptop. Before running this test, check the keyboard whether your keyboard is working or not. If your keyboard is not working, then you can use any working external keyboard to run this test. Follow the steps below to run the dell diagnostic test on dell laptop.
1. As soon as you turn on the laptop with the power button, you will see the Dell logo on the screen, on the left or right side of which, you will see the instructions of the F12 key to go to the boot menu, after which we have to keep pressing the F12 key continuously.
2. After this, the boot menu will open on your screen where the Diagnostic tab will appear, which we have to click.
3. After clicking on the Diagnostic tab, you will see that it will run the diagnostic test.
4. After running the diagnostic test, a popup of colour bar display will appear on your laptop screen in which you have to click the yes button.
5. After the colour bar display test is done, the diagnostic test will run entirely, and in this test, this diagnostic tool will check all your hardware parts one by one.
Note- Before running the dell diagnostic test on your Dell laptop, connect the laptop to the charger so you can also check your charger in this test. This diagnostics test takes about 20 minutes to complete, so if the laptop battery doesn’t have a backup, it becomes even more important to connect a charger for the test to run entirely
6. In this diagnostic test, the error code and message related to any faulty hardware part will appear on your laptop screen with a noisy sound. By reading this, you can determine which hardware part is at fault.
Dell laptop users commonly encounter some common error codes during diagnostic tests. Mainly, error codes like RAM failure, hard drive failure, battery failure, adapter failure, and CMOS battery failure are seen. Let us know about them in short.
This error code is mainly due to hard drive failure. The laptop’s hard drive is considered to be crashed or corrupt. To solve this, you can format our operating system and install Windows again to see if the new Windows is properly booting on our hard drive. If, after doing this, your drive is not responding, then you will have to replace the hard drive in you dell laptop and install new Windows. Only then will your laptop be back in working condition.
This error code is mainly related to RAM failure. Under this effect, the laptop’s display is not visible, and sometimes the blue screen error of Windows comes as soon as the show comes. To solve this, we can clean the RAM in the laptop and put it again and turn on the computer and see if the laptop is working correctly or not. If, after doing this, the display of your laptop does not come on and even after the display does not solve the blue screen error of Windows, then you may have to replace the RAM of our laptop.
This error code is mainly related to the battery failure of the laptop. Due to this, the laptop battery is considered harmful. To resolve this, you can try cleaning the battery connector and reconnecting it to see if the error code is still there or resolved. You must replace your laptop battery if the error code is still there. You can buy a Dell Laptop Battery online from any Dell Authorized Store or through the official dell retail store website of the deal.
