What Is The Problem When Your Laptop Wont Boot -coinwatch

.puters-and-Technology A sinking sense of dread and disbelief is almost universal for anyone who has turned on his .puter and found that nothing happened. When your laptop won’t boot, there are a number of possibilities. The problem may be merely an irritant or an expensive .ponent failure. The first thing to remember is not to panic. Your data is probably intact. Hard drives do not normally die instantly, and they typically show symptoms long before there is a critical failure. The .puter Shows No Evidence Of Power When you turn on a .puter, you should see small indicator lights or hear the fan running. If there is no indication that electricity is reaching the machine, make sure the power cord is properly plugged into the wall outlet and the machine. Outlets and power strips can fail. Plug the cord into a known working outlet. Make sure the laptop power supply is not faulty. Check the cord for exposed wire or damage. It is very .mon to have the cord-covering break with repeated bending and the unit be.es inoperable. Pet owners often find that their power cords have be.e tasty snacks for bored or teething dogs and puppies. Check the power jack to make sure it is firm and does not move. If it moves, the jack soldering is loosened from the motherboard and prevents power reaching the .puter. Few .puter technicians do board-level soldering, so the motherboard must be replaced. Problems with the memory can also prevent the .puter from booting. The RAM can go bad and must be replaced. Improperly-seated memory can also prevent a .puter from starting. Check to see that memory is properly installed in the slots, and test the memory in another .puter to be sure the sticks are viable. The .puter Turns On But Nothing Happens If you see the indicator lights and hear the fan running without the screen lighting up, your .puter has a problem with the video card, screen or video .ponents. The first step to troubleshoot this is to plug the laptop into a standard desktop monitor. If the problem is the laptop screen or the video .ponents, the monitor will display properly. If the monitor does not display, the problem lies with the video card. Unfortunately, the video card on almost all laptops is an integral part of the motherboard. If the video card is bad, the motherboard should be replaced. It is un.mon for an LCD screen to go bad suddenly. They typically display problems such as lines or bad pixels that worsen over time. It is more likely that video .ponents have gone bad. Inverter board and LCD light failures are fairly .mon issues with laptops. These .ponents are not expensive and can be changed without replacing the entire LCD screen. The .puter Begins To Boot And Spontaneously Shuts Down If the fan is clogged with hair, lint, soil and is unable to vent properly, heat can build up and force the machine to shut down. This is the .puter’s means of protecting itself from heat build-up. Check to make sure the vents are not filled with debris, that the fan is clean and spins freely and the .puter is not resting on a pillow or blanket that blocks the airways. Other issues may cause unplanned shutdowns. Prior heat damage or board level failures are all possible problems. Power instability from the electrical source, the power supply or the power jack can all be suspect. Troubleshooting .puter problems yourself can save expensive trips to the repair shop if the issues are easily solved. However, diagnosis by a skilled technician is often required to pinpoint and repair .plex or unusual problems. About the Author: 相关的主题文章:
