Here are some details on the possible reasons for Toshiba L450 to shut down suddenly and a few important tips to resolve the issue:
- Overheating problem
- Test out the heat sink
- Modify the fan settings
The major cause for the sudden shut down of your laptop is because of overheating of the case where the CPU is mounted. Overheating could be due to dust accumulation on the heat sink, hence not allowing dissipation of heat. The possible resolution to deal with the overheating problem is to keep the laptop dust free by cleaning out debris at the vents regularly. Note that a laptop has a much smaller cooling area in comparison with desktops and hence laptops are likely to accumulate dust a lot quicker than desktops.
Test out the heat sink
First thing you should do is to test your heat sink. This should be done to see whether there is thermal paste beneath the heat sink. If there is no thermal paste beneath it, then put some after making sure that there is no dirt in the heat sink. Since all these could contribute to sudden shut down issues, you are advised to check this beforehand.
The fan starts typically when running applications that require high CPU usage. Try to modify the fan settings in the BIOS so it runs all the time. Follow the instructions given below to modify the fan settings to keep it running regardless of the CPU temperature. First, reboot your PC and click the 'Delete' key to enter the BIOS settings. Then, go to 'PC Health Status'; modify the 'System smart fan control' settings from 'Enabled' to 'Disabled' and exit after saving the settings.
