Dismantle it yourself. I can tell you simply, first pry open the area with the interface on the top of the keyboard, and then unscrew all the screws underneath. Take off the keyboard first, then take off the optical drive and hard drive from the rear, and that's it. Once you take it apart and see the cooling fan, you will know what the problem is. In order to consider costs, HP's machines now do not pay attention to consumer customers at all. The fan sounds loud. If the machine has been on for two years, it means the fan is dusty. If the new machine is not working, it is because the machine generates a lot of heat, and the sound of the fan rotating with the temperature of the machine should be the sound of the hard drive.

The fan is out of oil. If it is under warranty, go to after-sales service. If it is outside warranty, buy sewing machine oil yourself. One dollar a bottle. Go online and search how to disassemble a laptop. I've had it on myself several times, and it's fine once I've done it. I occasionally use peanut oil, mainly for lubrication. Apply oil to the groove on the fan shaft that is close to the coil. After oiling, let the small bubble sit for a while before installing it. The after-sales service will cost you at least 150 yuan, but if you are not sure, you might as well find someone to repair it.

What to do if the laptop fan is noisy and the laptop fan is not spinning
Your fan heat sink is blocked by dust or there is too much sludge inside the fan shaft. , resulting in reduced fan performance. Ordinary dust cleaning can only clean the dust on the heat sink. For the sludge in the fan shaft, the fan must be disassembled and cleaned with pure alcohol, and then refueled. It can also be equipped with a cooling base, which costs tens of dollars each.
The most important factor in notebook cooling is the internal CPU fan. If it fails, the external cooling base will be in vain. External cooling can only cure the symptoms, while internal fans can cure the root cause. The external cooling base is only an auxiliary function. The most important thing is the notebook's own heat sink and fan.
How to clean the laptop fan
First of all, take a look at how many small covers there are on the back of your laptop. Usually there are 2-3, one is There are battery covers (some computers don’t have them), one is the hard drive cover, and the other is the memory cover (or use a larger cover for the memory and hard drive). CPUs generally don’t have covers, but some also have them. If so, then It's easy to say, the fan and cup should be welded together through copper pipes, or connected with screws. You can first find the CPU, and then check if there are any screws connected to the fan on the CPU. If there are, remove them. No. For violent disassembly, some have physical protection. If you dismantle it, you may never be able to press it on. The gain outweighs the loss. Then you can dismantle the fan. Generally, there are some sealing strips (to prevent the heat dissipation gas from escaping). If there is dust, you It is basically useless if you tear off the adhesive strip. You need to find a new adhesive strip to replace it, otherwise it will affect the heat dissipation. If it is welded, I suggest you ask a computer repairman to clean it for you.
