AI Have a Compaq Presario CQ62-225NR Notebook that randomly Makes a VERY loud Startling Grinding/Buzz Noise that doesn't last for but a split second, however, there is no indication of when it will happen and the weird thing is that I can't tell where it is coming from because I use my laptop for DJing and the sound gets amplified through my PA System... Help!!! I almost crapped my pants the last time it happened during a show and I'm fairly certain that some of my clients did!!!dding details will get you a faster solution from experts
Try and blow out the laptop with compressed air as it could be your fan making noise, make sure to leave the laptop on a flat surface, and don't press too ******* the palm rest. i say this because i have a dell 1545 and the hard drive is located on the left side under the palm rest and if i apply too much pressure i hear a slight grinding noise. let me know if this helps and please tell me if you're near the machine when it does this grinding sound.
If you need further help, reach me via phone at https://www.6ya.com/expert/joel_63c670a84e9f6a97
I'm always near the machine when it happens. But there have been times that I have stepped outside and it has happened and there were 3-5 short bursts of the noise and I had to run back inside and turn the master volume on my mixer down all of the way to stop it.
yeah i'd definetely lean the way of some sort of obstruction in the fan. if you feel brave or have the technical or mechanical skills you may try and take it apart. if you do this i recommend you remove the heat sync from the fan and get the dust from inbetween where the fan is and where it mounts to the heat sync i've seen caked dust in that particular are
I will definitely try it!!! I'm pretty brave, but I really don't know which area to take apart. The are that the fan is in doesn't have screws but it is adjacent to the battery. At least that is where the grills are...???

A webcam is built into the frame above the display screen on some HP notebooks-it is an optional feature on your model.
1. To test and configure the webcam on your notebook, go to Start> type Mediasmart and hit enter. In the Search results you will see the program HP MediaSmart Webcam. Click on it to open it.
2. Once the program opens, you should see an image produced by the webcam.
3. Click on Settings on the right side of the HP MediaSmart Webcam window, and then adjust settings-
Capture - Changes the delay before the photo or capture is taken, recording time (10 minutes is the limit for uploading to YouTube), video capture quality, and capture with audio.
Display - Change the brightness, contrast mirror image. You can also click Advanced Settings change capture filter properties.
Snapshot - Change the number of shots taken when you select burst photos and the shutter speed.
4. After you make adjustments, click OK to save your settings.
Hope this helps you-thanks for using FixYa.

This can be the fan or what is more common is just dirty fans and ducts. It takes very little dust or lint to stop the airflow in a laptop and if you have pets, gas heat or use near a kitchen (hot cooking oil vapours)
they will need cleaning as little as every 2-3 months. The more it runs with the particles in the air the faster it gets dirty. Can can blow this out using compressed air. You need to take the battery out then insert something to stop the fan from turning. The compressed air will turn the fan too fast and risk burning its bearings out. All you might see is one good puff of dust and thats all it is. You blow the air in through the fan and then reverse through the exit duct. That should knock the dust loose. You might have t pick out lint through the grill but get it as this will block more air and collect the dust faster. You can do it yourself or most shops will do it fairly cheap.
This is the cause of the majority of heating issues.I've only had to replace a handful of fans over the years. And I've ended up with free laptops where the dust was the only problem. Most times the fan doesn't move that much air so people think it is out. If you set your fan to max cooling under power properties you will get as much cooling at it is designed to do. Normally it will be off or very low speed until it hits a certain temp than will kick up the speed .
To replace the fan you need to take the laptop almost totally apart. The display comes off, the keyboard off and the case split and usually the motherboard comes out as well. Before you attempt this try blowing it out first. Then look at pictorial instructions so you have an idea of the work involved. It isn't tricky other than splitting the case but it is involved and you can damage the board with static.The fan will run you $20-$40 from a laptop repair parts place (search for laptop repair parts) Most shops do not do laptop repairs but send them away to a repair depot so you may have a bit of trouble finding someone to do it for you.
