Computers are amazingly complex machines, which unfortunately means that they are prone to a variety of problems. When your laptop won’t boot, it can be from software, hardware, user error or many other factors. Below is a list of the most common things which can cause boot failure and what you can do about them to try and fix your home or business computer.
Failure to boot is most often caused by an electrical problem of some kind. Your first suspect in this case should be the laptop’s power supply. It may have developed a short or some of the components inside may be worn out and no longer functional. Test the power supply in different outlets or try it with another laptop if possible. Also try jiggling the connector that plugs into your laptop, as sometimes the connection gets loose. If none of these tips bring you any luck, you will need to purchase another power supply. You can do this through your laptop’s manufacturer or a computer supply store. Be absolutely sure that you’re ordering the right one, because most power supplies are only compatible with certain laptop models.
If your laptop works fine when plugged into the wall but not when running from the battery, then the battery is your most likely culprit. After a while, rechargeable batteries like the one in your laptop lose their ability to hold a charge. When that happens, you must either purchase a new battery or continue to run the computer from AC power. If you choose to buy another battery, do your research first. There are many laptop batteries on the market which allow you to run the computer longer between charges.
A computer requires an operating system in order to function. If your laptop won’t boot, it could be because of a problem with that software. This won’t prevent the machine from turning on, however. It merely keeps it from booting up properly. To remedy this, first try inserting your operating system or computer recovery disc.
According to Westford Computer Services, the issue may simply be that some important files have been corrupted or deleted, in which case running the disc may allow you to repair or replace them. If you have no such disc or option, you may need to reinstall your operating system from scratch. If you don’t want to end up losing your personal files, a computer repair person may be able to help.
Chances are good that at some point, you’ve come across anecdotes of someone who failed to notice the obvious and chuckled a little bit while feeling glad that it wasn’t you. Everyone would like to believe that they’re personally immune to such blunders, but it’s an unfortunate fact that they can happen to anyone. When your computer won’t turn on, it never hurts to double-check that all the connections are in the proper place. Also make sure your battery is charged and installed in the correct position.
A computer’s processor generates a lot of heat. There is hardware installed on the processor to help direct it away, but if something isn’t working properly, it may not be enough. As a self-preservation method, computers are designed to shut down when the processor gets to a certain temperature. Due to obvious design issues, laptops are particularly vulnerable to overheating.
An overheating laptop can mean a faulty processor, a failing cooling fan, dust accumulation, obstructed cooling vents and using the machine in an excessively warm area. An overheating computer often becomes very slow and may shut down unexpectedly, possibly accompanied by an error message. It may even overheat before it can finish booting, indicating serious hardware issues. It’s best to have a professional look at it in this case.
