Any information or program you choose to put into use from this video is done AT YOUR OWN RISK. As a precaution, I recommend backing up any irrecoverable data before practicing any of the methods shown in this video.

This is an extremely basic and simple troubleshooting guide will show you how to possibly fix a laptop, netbook or notebook portable personal computer that, when the power button is pressed, powers up, the lights turn on, the fans spin, the hard drive and optical drives spin up, the connected devices such as USB receive power, but NO image, writing or text appears on the screen and NO POST beep error / message codes can be heard (essentially, the computer does not enter POST and boot the operating system from the initial bootup procedure that allows you to access the BIOS).

Typically, the CMOS (the component that governs which components are connected to your motherboard and how they interoperate between each other) has become confused and needs to be cleared AND / OR one or more internal components have gone bad (become faulty) and have to be replaced. This video will show you methods to remove and install SODIMM RAM memory modules and SATA hard disk drives (HDDs), which doing so reinitialized my system and allowed me to bring my eMachines d620 laptop back to life.


One beep when displaying logo – no error during POST

Long beeps in an endless loop – no system RAM installed or detected

One long beep followed by three short beeps – video card not found or video card memory bad

High-frequency beeps when the system is working – the CPU is overheating and the system is running at a lower frequency

If the steps in this video did not provide a solution to your problem, perhaps the desktop variants of this troubleshooting guide will provide the hints you need to diagnose and fix your portable computer’s issue:
