COMPUTER CAPACITORS:BENEFITS OF CAPACITORS IN COMPUTER

<span style="font-size: large;"><b>Meaning of Capacitors.</b></span><div><span style="font-size: large;">Capacitors are the electronic components that are used in electronic devices for the purpose of charge storage. All charges in electronic devices are stored in capacitors. The price of capacitor are very low compare to other components in electronic devices, but capacitors have the very high effect in computer system, at at moment when a capacitor failed it impossible for a computer or any electronics devices to switch on. </span></div><div><span style="font-size: large;"><b><br /></b></span></div><div><span style="font-size: large;"><b>COMPUTER CAPACITORS</b></span></div><div><span style="font-size: large;">Computer capacitors are the capacitors used in computer hardware system. This kind of computer capacitors are quit different compare with other kind of electronic devices capacitors. Computers capacitors are very sensitive and maximm performance compare to capacitors of other components.</span></div><div><span style="font-size: large;"><b><br /></b></span></div><div><span style="font-size: large;"><b>THE FAIL OF COMPUTER CAPACITOR CAN LEADS THE FOLLOWING </b></span></div><div><span style="font-size: large;"><b>1. BLACK SCREEN (BLACK SCREEN OF DEATH).</b></span></div><div><span style="font-size: large;">A computer with failed capacitor can give out the black screen of death. The computer can turn on well but the screen output is black. This situation occurs mostly when the capacitors toward the screen/monitors failed. The solution is to replace the blown capacitors with the new one.</span></div><div><span style="font-size: large;"><br /></span></div><div><span style="font-size: large;"><b>2. COMPUTER FAILED TO TURN ON/START UP .</b></span></div><div><span style="font-size: large;">A computer with a failed capacities may failed to start. This occurs when the capacitors that supplies power through the power system of a computer system failed. The failed  capacitors must be removed and replace and the computer must resume normally. </span></div><div><span style="font-size: large;"><br /></span></div><div><span style="font-size: large;"><b>BEHAVIOR/APPEARANCE OF FAILED CAPACITOR.</b></span></div><div><span style="font-size: large;">The outward appearance of a failed capacitor or blown capacitor its usually expand rather than normal condition. The blown capacitor can be removed by a hot gun or a blower that produces the hot air. Repairing of blown capacitors must be done with the very experience computer engineer of an expert computer technician.</span></div><div><span style="font-size: large;"><br /></span></div><div><span style="font-size: large;"><b>TYPES OF COMPUTER CAPACITORS.</b></span></div><div><span style="font-size: large;">There are several kinds of capacitors that are used in computer system for storage of charges and other computer power issues. </span></div><div><span style="font-size: large;"><br /></span></div><div><span style="font-size: large;"><b>Below are the common kinds of capacitors found in computer hardware components.</b></span></div><div><span style="font-size: large;">1.
