How to fix a Dell laptop that isn’t working

These are the steps to troubleshoot a Dell that won’t turn on. They range from the simplest and most obvious to more complex solutions.

  1. Check the power supply. You will need to replace your power supply if the lights on your computer don’t turn on when the power button is pressed. The cable may still be damaged even if it turns on when you plug your computer in. If this happens, you will need to check the power supply unit using a multimeter.
  2. You should remove any USB storage devices. Your computer may be trying to boot from the incorrect drive. If this fixes the problem, change the boot order to ensure your hard drive is at the top of the list.
  3. Power cycle your Dell laptop. Turn off the computer and unplug any external devices such as USB drives, printers, etc. After that, hold the power button down for about 15-20 seconds. The remaining power will be drained. Then, plug in the charger again and check if the computer turns on.
  4. Remove the battery. If your computer won’t turn on after the charging light turns on, it could be due to a problem with its battery. The battery on newer Dell laptops is not removable, but you can still replace it yourself if it does.
  5. Run the Dell PC diagnostic tool. The built-in diagnostic tool on Dell computers can help you identify issues when your computer fails to start up. Although it won’t automatically fix the problem, it can give you an error code to help you get the problem under control.
  6. Boot into Windows Safe Mode. Start in Safe Mode if your computer won’t turn on and doesn’t start Windows. There you can scan your computer for viruses and remove any programs that may be causing problems during startup.
  7. Remove malware from your Dell laptop. Your computer can freeze when it is infected with viruses or other malware. Boot your PC into safe mode if possible and run antivirus software to check for security threats.
  8. Reset the system BIOS. Clear the CMOS to reset your motherboard’s BIOS settings. Resetting the system BIOS to its default settings can fix problems with booting.
  9. Contact Dell customer support. For more information, visit Dell’s support page. Search for your model to find the right guidance. Your laptop may be eligible for free repair or replacement if it is still under warranty.
  10. Factory reset your PC. A factory reset is an option if your computer won’t turn on or turns on, but it still doesn’t work. This will restore your computer to its original state when it was first purchased.
