No POST stands for No Power-On Self-Test. This means that the Power-On Self-Test process, which occurs immediately after pressing the Power button cannot fully complete.
The fans can be heard, but nothing is displayed on the screen. Beeps are heard, and the LED lights are blinking in a repetitive pattern. Common causes include a bad connection between components or defective hardware.
In this video, we will walk you through the steps of how to fix No POST. First, shut down the computer and remove any external peripherals. Turn on the computer and check if it powers on.
If not, let’s try the next step. Perform a hard reset on your PC. Shut down the computer and disconnect any external peripherals. If you own a laptop, unplug the power cord and then remove the battery. You should consult your laptop’s manual to learn how to properly remove the battery.
If you have a desktop, you just need to unplug the power cord. Press the Power button for 30 seconds to drain any residual power. Afterward, reinsert the battery for the laptop and connect the AC adapter. For desktops, reconnect the power cord. Now, turn on the computer and test the keyboard to see if it responds properly. Are you still having issues? Try this. Try resetting the Real Time Clock.
Note, that not all models will have this option available. Power off the computer and connect the system to a power outlet. Press and hold the Power button for 30 seconds.
After releasing the Power button, the system will restart several times. After the reset is complete, the Dell splash screen will indicate the reset was a success.
Repeatedly tap "F2" at startup to enter BIOS. Once in BIOS, configure the "Date", "Time", "Boot list", and "SATA" operation, according to system specification. Please contact our Tech Support if you need assistance with your system’s configuration.
