The sudden shutdown of the laptop in sleep mode may be due to the following reasons:
1. Power supply problem: check whether the battery is exhausted or the charger is plugged in properly.If the battery runs out, the laptop will automatically shut down to protect the hardware;If the charger is not plugged in properly, it may also lead to insufficient power supply and shutdown.
2. Overheating problem: When the notebook overheats, the system will automatically shut down to prevent hardware damage.Try cleaning the heat sink and fan and make sure they are used on a flat surface.
3. Software conflict: Some software or drivers may conflict with the operating system or other applications, resulting in system crash.Updating the latest version of drivers, operating system patches and software can solve this problem.
4. Virus infection: When the computer is attacked by malicious software or viruses, abnormal behaviors may occur, including sudden shutdown.Run anti-virus software to conduct a comprehensive scan and eliminate any potential threats.
5. Hardware failure: If the above methods do not solve the problem, the shutdown may be caused by hardware failure.For example, there may be problems with hardware such as memory module, motherboard or power supply, which requires professional maintenance.
If the above solutions are not effective, it is recommended to contact the manufacturer of the notebook computer or let professional technicians check and repair.
The reason for the crash when entering the normal state from standby is that the cooling fan stops.When the system enters the standby mode, it will automatically reduce the CPU frequency and fan speed to save energy consumption.However, early CPUs, due to their low frequency and low heat generation, can only rely on the heat sink to meet the heat released by the CPU even if the fan does not turn when idle. However, today's CPUs are generally high in frequency and emit more heat. When they are in standby, the fan does not turn,The CPU will be hot and hot. If the CPU is overclocked, the heat will be even greater, so it is easy to cause a crash after restarting to the normal mode.To solve this problem, you can set the fan in the BIOS so that it does not stop in standby mode. When you start up, enter the BIOS, select the Power Management option, press the Enter key to enter, find the Fan Off When Suspend option, set it to Disable, save and exit, and then the fan will continue to rotate in standby mode to avoid crash.
