If you own a Dell Laptop, you will likely have the ability to run advanced diagnostics to give you an indication of why your laptop isn’t booting. These are called the PSA Diagnostics (Pre-boot System Assessment) and they are accessed by pressing the F12 button when you see the Dell splash screen in the very beginning of the boot cycle. All laptops may nor have this ability or might have a different set of diagnostics to run. The PSA Diagnostics are very similar to a beep code issued by the BIOS but in graphical format.
If you are able to run the PSA Diagnostics on your Dell laptop, write the code down and compare it to the list below. In most cases, you will need to contact dell support or take the computer in for servicing. But if the problem isn’t serious, you can sometimes correct it yourself. Note: if your laptop is still under warranty, be sure to contact Dell before attempting to do any repairs yourself.
