You don't want parts flying off the computer or breaking off the fragile fan fins. Also, if you have access to an air compressor, do not blow too close to the fan or other parts, and adjust the pressure to the lowest setting if you can.

However, if that is all you have, then take out the fan and do it at a safe distance from the computer. You don't want spraying that stuff on electronic components. So called air dusters have some type of gas inside the can that propels the air, and they turn into liquid when they come in touch with the ambient atmosphere. But the air from an actual air compressor, not the cheap compressed air you get in cans. Either while the fan sits in the computer, or if it can be easily removed, remove it and blow it out and then put it back. If you do, please take precautions and wear antistatic bracelet and avoid touching any electrical parts with the nozzle.īut the best thing is to blow the dust out. You could do that, and suck out the dust. Now if you do decide to clean it, and you can't get a replacement or it's some rare expensive assembly that needs replacing altogether, then do not use a vacuum cleaner. so it would continue working but at reduced performance, slowly killing that CPU of yours one MHz at a time. for instance, the fan can be 'semi-failed' so to speak, or degraded if you will. Modern systems are built so that the computer will automatically shut itself down to protect itself when and if a critical component like a fan fails or the CPU reaches it's junction temperature.

Next to static electricity, the next worst enemy of CPU is temperature. Fans can fail and they do fail, and when they do, even though they are clean, it can cause the CPU to overheat and get damaged. in either case.ĭon't clean the fan, replace it! If it has been spinning for two years or more, and you are at it and want to clean it, you might as well replace it. In worst case you will have to replace the motherboard as well, if it is damaged as well, or it is the one damaged and not the CPU. now i gottashop for laptop but i think i am done with hp. so i might just have to buy a new laptop. my friend is looking at it for me tomorrow he thinks it could be the power supply. i hit the power button i see the blue power light, it makes the noise like its booting up but then nothing. But if the CPU is damaged due to static electricity then you can try replacing it. no it won't do anything the screen is just completely black. You may have touched it with the plastic nozzle attachment whilst it was statically charged, which could have caused a small electrical charge to jump onto the motherboard. From the looks of it that laptop's motherboard is directly accessible when the fan is exposed. Using a vacuum cleaner is known to cause static electricity that can damage sensitive electronics. How did you clean it and with what? Suck or blow? Not sponge, soap and water I hope?.

Hp dv6 wont turn on
