My compaq presarion won't start up and the led in the charger hole won't light on


Try removing the battery and only using AC power. If the power
LED on the power brick does not come on then replace the power supply. If it works with just AC then replace the battery. If it still doesn't work, warranty replace the computer.

The light charger hole is not on


Posting the same thing twice is annoying and counter productive.

Windows boots but i get no picture on screen


The LCD monitor may have a back light problem. This can be caused by a faulty inverter circuit board which supplies high voltage to the CCFL lamp or the CCFL lamp is faulty.

Our compaq monitor will not go on. It is plugged in and the green light goes on when the button is pushed, but nothing comes up on the screen after moving the mouse. Our Presario computer is turned on. Any...


Make sure it is properly plugged into your computer too. (blue headed cord) should go from the screen to the computer. Make sure the cord is not damaged.

There should be a total of two cords needed (one for power (black) and (one from the computer to screen (usually blue))

Acer AL1715 going on and off (LED blinking)


Hi maxwell,

Firstly check for the surrounding components like th coupling resistors for a short. Change them, then look for leaky diodes (a diode shows low resistance when connected to a multimeter with correct polarity and MUST show infinite i.e. NO resistance at all when polarity of the meter testprods are reversed) As for the deformed capacitor change it with similar type, voltage and size.
VERY IMPORTANT: Make sure you put in the new one back in the same polarity (since it is an electrolytic type capacitor from what you mentioned in your querry) elase the new one will explode if the polarity is wrong.

Better still, if you are not good at soldering components that are so closely attached on the circuit board, just give it to an authorised service center in your area.
