HP laptops have become immensely popular among users around the world. These laptops have great autonomy and are extremely portable. However, like all other technical devices, HP Notebook PCs are subject to technical issues from time to time. The error code 90b of the HP laptop, which users often complain about, is one of those errors. Users often see this error code when they start their HP notebook. This error code indicates that a fan has stopped working properly. Whatever the cause of this error code, you must resolve it as soon as possible.
Typically, the HP 90b error code indicates a problem with the heat sink system. This could happen for two probable reasons.
- One possibility is that the system fan does not turn at all. If it runs, it may not run properly, resulting in the HP error code.
- If the temperature inside the housing is too high and the fan does not rotate properly, the fan may not be able to dissipate the generated heat.
- The error code appears so that the laptop is not damaged anymore.
There are some proven techniques that you can implement to eliminate the system fan error on HP laptops. However, you can solve the problem effectively by following the procedures mentioned below:
You may notice that the system fan is running. But your computer can generate hot air at the same time. If this is the case, you will need to clean the outside vents. In addition, you will need to blow air through the ventilation openings to eliminate dust particles.
Another method to resolve this system fan error is to perform a hard reset. If you perform a hard reset, it will help reset the existing thermal values in the memory. Once you’ve done this, you’ll be able to use your HP notebook for a short period of time. You can use to back up essential data on your laptop.
Another simple trick to get rid of the error code is to update the BIOS. If all else fails, you will need to replace the system fan to prevent this error message from appearing. Nevertheless, you should keep in mind few things if you want to implement these measures. First, you need to make sure that you remove the dust particles from the internal cooling components. In addition, you must ensure that the fan cables of the CPU and system have been securely connected to the motherboard. You may also need to replace the old thermal compound heat sinks as well as the integrated circuits with a new one.
