Dell Laptop Troubleshooting :

 

There are few things you can do before going for a dell laptop repair.

No Power

Computers have a power indicator that glows when it is receiving power. On Desktops the front panel of the computer case has LED near the power button. Try the following steps to resolve a desktop no-powering situation:

Try a different wall outlet, and power it on
Reseat the power cord which is connected to “Power Supply” of the tower and power the Desktop on
Swap the power cord of the Monitor with the system power cord and power on the Desktop

No POST

The term POST refers to Power-On Self-Test which is a series of checks the computer goes through whenever it starts. If the computer fails any of these tests, it will stop the start-up process.

Indications of a failed POST include:

If the computer is displaying the Dell logo and does not move past that point, it has probably failed POST.
If the power indicator lights up and it is amber or orange, this is usually an indicator that it has failed POST.
If you see text on a black screen, the computer is currently performing the POST. If the computer stays in that condition and does not move past it, it has probably failed POST.
If the video screen displayed anything at all during the startup process but is now black, this probably indicates that the computer failed POST.
If the computer is beeping or if Caps/Num/Scroll Locks are flashing, note if there is a particular pattern in which it beeps or flashes.

No Boot

After the computer completes the Power-On Self-Test, it will attempt to boot the operating system.
If the computer advances past the Dell logo screen and then hangs up attempting to load the operating system, it is most likely a No Boot issue.

No Video

If the power indications are normal but there is never any video seen on the computer’s display during the startup process, this probably indicates a No Video issue.

If you have a desktop computer and the monitor has its own power supply, make sure the monitor has a power indicator showing that it is turned on.
