This video explains that if a computer doesn't start normally, the problem can usually be categorized into one of four issues: no power, no POST, no video, or no boot. Identifying the specific issue can help find a solution or communicate the problem to support. This video also provides a brief description of each issue and suggests visiting Resolve No Power, No POST, No Boot or No Video for help resolving the problem.
If your computer doesn't start normally, the problem usually fits into one of four categories. No power, no POST, no video, or no boot.
Knowing which issue you have can help you find a solution yourself, or communicate the problem more clearly to Support. If your computer doesn't respond at all when you press the power button, no lights, no beeps, or fan noise, then the issue is no power.
If your computer does power on, but beeps or flashes lights in a repeating pattern while the screen remains blank, the issue is no POST.
If your computer seems to power on normally, but nothing is displayed on your screen, the issue is no video.
If your computer starts up normally, displays the Dell logo, but then fails to boot into the operating system, the issue is no boot.
To get help resolving the problem, go to dell.com/support, and search for no power, no POST, no video, or no boot. Or check the relevant section of SLN292599.
