This kind of operation is an emergency mode for the battery, and because of it the battery life most likely will be greatly reduced. So they are working on these devices with both – battery and power supply – connected constantly and simultaneously. Many users are buying laptops to use them constantly at home or in the office. Most often, the laptop turns on and immediately off due to the battery malfunction. The easiest way to fix this problem is to disassemble the laptop and clean it properly. As a result, there will launch an overheating protection which will make your computer to shut down. If the coolers of a portable computer are very dirty, all its components (CPU, graphics processor, hard disk, and so on) will overheat almost instantly after you turn your laptop on. This will allow the laptop to work as long as possible, without having problems with overheating. Dusty laptopĪccording to the recommendations of all laptop manufacturers, every 6 months these devices must be sent to a service center for professional cleaning. There may be problems with replacing coolers in a laptop, because often it is quite difficult to find laptop parts if it is not of the most common model. In this case, it is necessary to determine the cause of their failure and repair or replace them.
It is much worse when the CPU overheats not because it is lacking thermal paste, but because of poor cooling when both – coolers and radiators – do not work properly. If this is the case, you will need to replace the thermal paste, which can be done independently, if there are no difficulties with laptop disassembling. In most cases, it occurs due to the absence of thermal paste (or it might be present but way too dry). CPU malfunctionsĪ common reason for a laptop to turn on and then immediately off is CPU overheating. In such a situation, it is recommended to check the hard disk by installing it into another computer (meaning the one that has no problems at boot). If the hard drive itself or the operating system files on it were damaged, the laptop may turn itself off before it is fully loaded. Another common cause of hard drive failure is a sudden shutdown of a laptop, due to which the drive must make an emergency stop. Hard driveĭamage to the HDD or SSD may occur for various reasons, for example, due to physical damage if laptop falls down. Let’s take a closer look at the main malfunctions that may lead to a spontaneous shutdown at boot.
That is why quite often various laptop elements simply fail. It is not an easy task to arrange all the necessary components in the laptop case especially because doing that one has to think really carefully how and where to place cooling system. Laptop turns off because of hardware malfunctions Laptop shuts down at boot because of software problems Laptop turns off because of hardware malfunctions - Hard drive - Processor malfunctions - Dusty laptop - Battery - Short circuit - Faulty power supply unit 2.
