Strange sounds from my laptop.
A win7 question but I included win10 in case it happens there too and
because I think a lot of win7 experts now only read win10. The sound on my Dell E4300 Latitude laptop will work fine for long periods of time, but sometimes it makes strange noises. single tones for 3 or 4 seconds, then a different tone. Baaaaaaah..Buuuuuuuuh t hen work aagain, then maybe a third tone for 3 or 4 seconds. Anyone know what causes this? It used to be so bad I had to stop listening to webradio, but it tapered off, and then it was back and I decided to tun the sound off, at the Speaker icon in the systray. Now there is a circle with a slash over the icon, but... sometimes, less often, it still make these sounds. And sometimes I hear a loud voice, probably the host of the webradio station, for 3 seconds. I turned off the sound at the webradio program, but I still hear the tones a little bit. How is all this possible? Is my laptop haunted? |

Do the sounds you mention sound like that? If not, play each of the sound events to see if one of them is what you hear. Unplug all USB devices. All of them, so you'll be stuck using the touchpad for awhile. Reboot. See if the noise happens again. Test for, at least, twice however it took before for the noise to happen. Or is the sound not audio playing through the speakers but noise made by something other than the speakers? Like there's too much dust on the cooling fan, or a friction sound of the fan against a cable, a noise from the HDD, you left a disc in the CD drawer, or some noise other than coming out from the speakers? If you connect a pair of headphones, do you hear the sounds in the headphones? Back in the Sounds app, which device is selected for the playback device? |

There doesn't seem to be much air coming out of the vent either, though I don't know how much there should be. I bought this used 3 or 4 years ago and I don't know how much the prior owner used it, or if he worked in a flour mill/haunted house (What has the most dust?) As soon as I get the new desktop, I'll take this apart, remove the dust or replace the fan. Replaced the fan and all is well again. Okay. Thanks and thanks everyone. |

As soon as I get my desktop bought and loaded, I'll check out the cooling and clean it or replace the fan. Fans get noisy due to out-of-balance vibration when their fins collect dust which never distributes equally balanced across all fins. Use an ear swab to rub the dust on the fins. Just blowing won't remove all the dust because it gets impacted onto the fins due to their rotational speed. Follow by blowing the fans with a can of compressed air; however, use a straw or an ear swab to keep the fins from spinning when you blow air over the fins. You don't want the fan spinning when not doing so due to powering them. I'm not sure with a laptop that you can get an ear swab on the fins of the fan. In desktop PCs, axial fans are used for airflow. In laptops, radial fans are used, because they can push more air using the same, or even less, power than a radial fan; however, radial fans are noisier than axial fans. You may only be able to blow air through the radial fan, but you should use a long stirrer stick or something to keep the fan from spinning when not powered and you're blowing air through the fan (which would make it spin). You'd have to dismantle the laptop's case to get at the fins, and you'll only access a short span of the fins near the hub. The problem with blowing air from the outside is you will blowing the dust back inside the laptop's case. You have to dismantle the case to blow the air around the hub, so the dust exits the case.

You have to dismantle the case to blow the air around the hub, so the dust exits the case. You could always suck rather than blow (ensuring there's no dust near the inlets). With negative pressurization, the maximum change is from ambient pressure down to a vacuum, so maybe a change of all of 1 atmosphere (14.7 PSI). With positive pressurization, you can achieve far more than 1 atmosphere of change. Standard scuba tanks get charged to 3000 PSI. However, I would never connect a hose without a regulator to a scuba tank to dust a laptop; else, I'd blast components off the mobo, the fins would break off on the fan, and other damage. A mechanical scrub followed with a duster can (or compressor with regulator or variable nozzle) would be far safer. If suction were sufficient, why do duster and carpet attachments for vacuums have brushes (fixed or rotating)? Suction alone is not sufficient anything but loose dust. You can use hundreds of duster cans and leave a vacuum running weeks to blow or suck dust off a fan without removing the impacted contaminants. You aren't removing just dust (lint, hair) but also the grime that made the dust stick to surfaces. As an example, if you have a table fan and it collects dust, just placing a vacuum hose near the fins won't clean off much but the most loose dust. You use a duster brush to scrub the fins. Same if you were to blow air at the fins. Since you can achieve higher positive pressures than the change down to a vacuum, you could use an air compressor and concentrator nozzle to use more force to get the filth off the fins. However, the fan's fins are not boat propeller blades, so you could break fins or cause nearby damage with excessive PSI. I prefer not exposing electronics or fans to such high pressures. If it won't come off with a duster can, I use an ear swab or anti-static brush for a mechanical scrub. For table fans, I use the duster attachment w/brushes on the end of the vacuum hose. Air turbulence isn't as effective as mechanical agitation. Since the air isn't filtered, it's more than just air passing through the inside of the case, and which gets the dust sticking onto the fan's fins, chips, and everywhere else inside. It's not like the fan is super powerful that it can suck air through a cinter filter. I've not seen any laptops that incorporate a HEPA filter (which is restrictive to airflow and would require a more powerful fan hence severely reducing battery life). The fan impacting the contaminants along with the dust in the unfiltered air makes it stick to the fins. It's not just dust. It's also grime: cigarette smoke, cooking oil/grease, air fresheners (spray or scented oil), candles, etc. That vast majority of laptop use is not inside a clean room. You won't do much cleaning with suction. You can get higher pressure hence more force with blowing; however, at the pressures typically available via dust cans or compressors, you may not remove all dust due to the grime that makes it stick, and it's dangerous to use extreme pressure. You could break off a plastic fin from the plastic hub in a thin laptop fan. If a dust can is insufficient (which works better than suction), do a mechanical scrub. Suction works on dust bunnies, but those aren't what cause an unbalanced fan that causes the noise and premature spindle/bearing failure. Dust bunnies could block air flow, so you might hear additional noise due to increased turbulence, but users are unlikely to hear the pitch change when using their laptop. Suction might reduce airflow blockage, but it won't clean an unbalanced fan to eliminate that noise. From https://www.youtube.com/watch?v=nrjrMLw0WiU, it'll take a bit of dismantling by the OP to get at the inlet side of the fan to do a clean job that removes the impacted grimed dust off the fan's fins. Suction won't work. Blowing into the outlet vent won't clean the fan fins along with shoving the loose dust back inside the case. Shops will charge $80 for a clean job, because most of the work and their time is dismantling and reassembling the laptop, not the cleaning effort. A shop that just blows air into the fan's outlet vent or uses a vacuum is a waste of money, and they won't be fixing an out-of-balance fan making noise. That job would be a scam. |

I hope so, if you count maps and views, I've learned more in the last 3 years than any 3 y ears since I turned 12, and I remember most of it. I look at a map of new places I've been and I can picture the road, the buildings, the parking lot, of hundreds of places.
