Ordinarily a machine that will not power-up may have unintentionally become unplugged or imaginably a cord may have become free. The following enumeration is intended to eliminate a power connection or disconnected cable as the origin for a device not powering up.
* inspect to be sure that all power switches are in the on position. Check the rear of the microcomputer case. Many times there will be a power switch on the rear of the laptop alongside the position where the power wire attaches to the personal computer. Be sure that it is in the proper position.
* Inspect to see that the voltage switch is set correctly. In the U.S. it should be set to 110v/115v. You will find the voltage switch located on the power supply, which is normally situated on the rear of the desktop computer also near the power cord.
* Make confident that the power cord to the laptop computer is plugged securely into the rear of the laptop computer.
* For laptops make confident that the transformer is plugged into the laptop solidly.
* Trace the power cord from the personal computer back to the receptacle in the power strip or wall and make convinced that the receptacle is really hot'. You can test this by taking a established working appliance such as a lamp and testing the actual receptacle that the personal computer is plugged into to make convinced that it is in truth working.
* If you see a power light or other L.E.D.'s on the computer case lighting up but the monitor is not showing a display then you may not have power to the monitor or the video wire may have become disconnected. Make satisfied that the power cord to the monitor is firmly plugged into the back of the monitor. Trace the power wire from the monitor rear to the receptacle and be certain that it is connected to a live outlet.
* Check to see if the monitor video cable is secured to the rear of the monitor and that the other end is solidly connected to the video port on the personal computer.
* Still no luck? Try unplugging and re-plugging all wires. take off all cables from the personal computer including power, monitor, mouse, keyboard, printer, network, and any other coupled devices. Make sure that you know where the cables go back again! If not, label them.
* Now re-plug all the cords and wires and try powering up again.
