Cool settings laptop BIOS and OS?
There’s no universal standard for what BIOS settings are user adjustable for a given brand or model of laptop battery such as battery toshiba satellite a75 s209 pa3383u-1brs. If you can lower the temperature at with the fan automatically powers up and you’re having overheating problems, it can’t hurt to do so, though you should also try the less invasive cleaning techniques given at the end of this flowchart. There are a large number of OS (Operating System) settings that affect the amount of heat the laptop will generate, from the speed of the processor and the brightness of the screen to the efficiency of the cooling system. The manufacturers try to give the user as much control as possible, but if you or another user ran the cooling control down to the minimum to reduce fan noise or extend battery life e.g. toshiba satellite A70 battery, it may be time to compromise.
On the other hand, if the settings are all on the defaults, the fan never comes on, and the system is overheating, it’s either a fan failure or a problem with the control circuit. The fan itself is a replaceable DC fan that usually can be replaced without removing the heatsink (if it’s mounted directly on the CPU or graphics processor). One simple test for notebook fans is to blow on them. If the fan doesn’t spin, either the bearing has failed or something is melted or jammed, because the motors are tiny. Testing the control circuit is an open-unit bench job that I don’t recommend unless you are an experienced technician. It’s easier to just replace the fan with a known good unit, and if it still doesn’t work the problem is in the controller or the power supply to the fan.
