Several minor issues that may seem insignificant to can prevent your system from initiating a boot after it has been powered on. For instance, if the battery is completely discharged and it is not plugged to an AC outlet, it may not start. Also, if the adapter is not properly connected to AC mains, and the battery is down completely, the laptop may not start. If the power button is faulty or completely damaged, then it may not be able to initiate a close circuit to enable system startup.
It is important to carry out detailed troubleshooting before concluding that the system has failed or crashed completely. Ensure that the battery is well fixed; allow the battery to get charged for a long period of time. Check the adapter output voltage to see if it is compatible to the required specification. If the adapter is found to be in good working condition, take the battery away and plug the system without its battery to the AC mains with the adapter. If the system turns on, the battery is damaged and has a short circuit internally affecting the entire system. The power button should be held down a little bit longer to ensure its making the desired contact.
Other problems could be that the internal power circuitry has been blown due to an unexpected power surge. With this, the entire system can never come up until the entire circuit board is replaced or worked on by a professional. BIOS (basic input and output system) failure can also prevent the system from start up. When the boot sequence cannot access the BIOS for instruction on how to progress in the system start-up, start up fails automatically. If in any way the hard disk is disabled, the startup boot sequence may not be correct hereby resulting to a boot failure and system might not startup. For a system to complete a standard start up process, it must pass the POST (power on the self test) routine to ensure the readiness of all affiliate components in the system.
