Re: Noisy and pulsing interference on cordless pho...

My biggest mistake was to enter into a BT broadband contract (free for the first 6 month's) to which I terminated early my previous contract with penalty. Seven month's on and with no resolve to the continued line interference/broadband dropping, I shall soon be leaving BT behind, vowing never to return.
Endless conversations with India (polite most of the time but useless), conversations here in the UK which were little better and letters un-replied to, left me with no option but to relay all this to Ofcom. This problem which until joining BT never existed before. Broadband and Line Engineer visits (40 minute visit including travel), filters checked/replaced endless times, replacement router, master socket replaced, caller display lost during all this time, (although mysteriously returned a week ago after my last and final call), and line back to the exchange checked more time's than I can remember, have left me with no explanation and no patience. To cap it all, I have recently received a £99.00 engineer home visit bill !

Is this the first time you have been using broadband on your line, or where you with another ISP that used your telephone line for broadband?
What you describe has been reported before on this forum and was resolved.
Would it be possible for you to connect things up as shown on the link below, and see if the noise is still present on your phone. Thanks.
Testing from "test" socket
Also, do you still get the pulsing noise if you plug in a normal phone, as it could be the wirelss in the home hub, interfering with the cordless phone?
There are some useful help pages here, for BT Broadband customers only, on my personal website.

Satellite R630-155 - Fan is too noisy and SSD upgrade

I am the owner of a Toshiba Satellite R630-155 (Core i5-480). My problems are:
1. The fan is too noisy and never stops. In normal operation (browsing and general office work) there is a constant high pitch noise that is audible three to four meters away in an office environment - in high load you just can't stand it!!! The fan never stops... even when you are doing nothing...
2. Heat is a big problem. The bottom of the laptop is constantly overheating and i have to place it on my desk in a way that the bottom left corner is outside of the table so it can breath fresh air from below - if not, the temperature rises and the (loud) fan is unable to keep up. When i work with the laptop while sitting on a sofa, i have to place a thick book between the laptop and my legs. The book must be thick (more than an inch) with hard covers, otherwise the heat passes through the book!!!!
3. Last (but not least, i just mention the biggest problems here) it's the problem with SSD installation. I bought a used Corsair F80 (80Gb SSD) from a friend, but i was unable to use it with the Toshiba - the BIOS was not detecting the disk. I tried installing all latest firmware updates for both laptop and SSD but i had no success. Then i gave the disk back and i bought a brand new Zalman 128Gb SSD (SSD0128N1 Sandforce) but i had exactly the same problem. I contacted my local Toshiba support and after a lot of conversation the only answer i got is that the laptop is not compatible with those SSD's and this is acceptable by Toshiba and not their problem. They told me that if i need an SSD upgrade i can only go for the Toshiba SSD that is installed on the portege series, which is sold by Toshiba for a ridiculously expensive price - about $500 for 128Gb. I contacted the European support center and i got the exact same reply. I searched on the Internet and i found someone else with the exact same problem with a Corsair 128Gb SSD - he found that the laptop detects the SSD after ten to twenty reboots. I tried that and it was true - after a lot of reboots the laptop detected the Zalman disk and i was able to install Windows 7 successfully, but the process is unacceptable. Also the disk is benchmarked by official sites at the speed of an OCZ Vertex 2 128Gb (and slightly better), but when i ran a benchmark in the Toshiba, the results I got were below half of the advertised speed. Same benchmark in another machine for the same disk, resulted in the advertised speeds.
Shame for Toshiba... nice design and portability but everything else is a big flaw. Their support in non existent and they do not value their customers. I feel they stole my money and I'll never buy a Toshiba laptop again.
Sorry for the big message, but I need I have to warn potential customers. Can someone help me with any of the above problems? Do you have the same problems too?
To be continued...

Hi buddy,
Regarding the fan and heat issue: Did you make BIOS update? Friend of me has Satellite R630 too and he told me that fan activity with new BIOS version 2.10 is reduced. Furthermore the notebook is cooler than before so I would recommend installing this update. You can download the BIOS update here:
http://eu.computers.toshiba-europe.com > Support & Downloads > Download Drivers
But before you start the BIOS update you should consider the following tips:
-Run update as Administrator only
-Unzip all files from zip archive before you start the update file
-Close all running programs and also the antivirus and firewall
-Make sure that battery is fully charged
Regarding the SSDs its always a little bit complicated installing 3rd party products and nobody can guarantee that such parts would work. You are always on safely side with original Toshiba spare parts.
Everything what you can do is installing the newest firmware for SSD and hope that it works but who knows maybe the BIOS update will also help you in this case ;)

Why is my fan working so noisy and speedly?

I bought a new macbook air two months ago. My model has 13¨ display, 128 GB SSD, 2 GB RAM, etc.
Sometimes, specifically while playing flash videos, fan is working so noisy and speedly and macbook air is running so slow as you can feel easily.
I searched; there are some programs like Coolbook that promise to solve this problem.
But I'm looking an officially solution from Apple. Is there?
Thanks,

Hi muhendisce,
If you're looking for an official solution you're not going to find it here, this a user-to-user discussion group. You'll need to get on the phone with AppleCare or bring the machine into an Authorized Service Provider / Genius Bar (Retail Store).
If you're watching flash heavy content expect the CPU & GPU to be taxed and as such the fan to come on. But it shouldn't be noisy (grinding noise).

Scratchy noise coming from top end of keyboard. Not effecting performance but very noisy and worrying! What is it? Is my computer seriously damaged? Is it easily fixed? Thanks for any help

It would be helpful if you were to identify the model of MBP you have.
The noise makers on a MBP are the fan(s), the HDD and the optical drive. Can you locate the exact position where the noise is coming from?

Mpd and pulse problem - Connection refused [SOLVED]

I'm having problems getting mpd to play nice with pulse-audio. Pulse is installed and works with vlc, mplayer, flash, etc. just fine. When I try to play through mpd the song in the gui simply shows a status of "paused" and the following gets written to the mpd.log.
Advice is appreciated.

The pulseaudio wiki suggests that a 'pulse' group and 'pulse-access' and even 'pulse-rt' groups may be required? I have used mpd for a year now with no such groups on my system.

Measure period and pulse duration of ttl level continuously

Hello,
i want measure the period and pulse duration continuously of two signals with an usb-6009. Every 8s there is a high pulse for 15ms. I want to measure length of the pulse and pause. Can someone help me? I can`t get a start up with this problem.
The four measurements (two channels two measurements per channel) are a dataset. This dataset should be stored in a textfile continuously. But this not a problem.
thankyou
Schwede

Hi Schwede,
Thanks for the update - Im now back in the office!
I have some bad news, your using the wrong device - you need a device with at least two counters - to acquire for two signals. But, secondly,(see specs), the counter measurements support by the USB 6009 doesn't include pulse or width measurements.
The specs for the USB 6009:
Counter
Number of counters ................................1
Resolution...............................................32 bits
Counter measurements ...........................Edge counting (falling-edge)
To acheive the functionality you require I would recommend a USB 621x:
Number of counter/timers ............... 2
Resolution ....................................... 32 bits
Counter measurements.................... Edge counting,
pulse,
semi-period,
period,
two-edge separation
Also, this link is rather useful also:

Clicks and visual interference from all footage from xf 300 mxf files

I'm having problems with clicks and visual interference from all footage from xf 300 mxf files in CC have formatted cf cards on camera as this has happened before and had camera checked with no problems has anyone else had this problem as cannot find anything anywhere. The cards are Sandisk Extreme 32GB and the manufactures say its not their card??

Kevin, thanks for your prompt response.
I've finally had the time to try this again and understand it.
I wasn't using the media browser. I was using the import function from the Project panel, which is how I have always loaded clips. I had never used the media browser and assumed that one ended up using it anyway no matter which front end used for import. i.e. I thought the media browser was simply the back end file selector dialogue.
So I see that (only) the media browser will import spanned clips as one unified clip into the sequence, which is an improvement for sure. I do think that import of the Project panel should work the same way.
I initially had a problem though, as my top level directory above the numbers clip dirs was not CONTENTS. It had to be renamed to avoid conflict with other CONTENTS clip set in the same project. So the media browser refused to load the spanned clips together, but would allow me to load a single clip. It wasn't until I guessed, and renamed my top dir back to CONTENTS that things worked and the the View as dropdown showed the magic Canon XF option.
I suggest this implied requirement be made clear in the manual, noting that the top dir must be named CONTENTS for this to work. Yes, I believe that's the MXF standard, but many people will rename their parent directory so multiple cards can be copied into the same project directory, instead of having yet another single-entry directory above the CONTENTS directory, like CARD1 CARD2 etc.
I beieve that the software is at fault and should be changed - if it can see mutliple numbered MXF dirs at the same level, it should simply deal with them. I know you can't fix that, but please warn people.
Anyway, thanks again for your reply. It got me on the correct path to a solution.

Canon MF8350CD MFP is noisy and grinding, but still prints.Is there a technical manual available?

Is there a service manual available to help trouble shoot a MF8350CD MFP? Its noisy and grinding, but still prints.

Hi bryanmonger.
Please note that Canon does not provide service manuals or instructions on disassembling the machine. If you are hearing a grinding noise in the machine, there could be a few causes, such as, the type of toner cartridges you are using, a loose or broken part in the machine, or an issue with one of the assemblies.
We recommend that you contact us at 1-800-OK-CANON (1-800-652-2666) for further assistance. While I understand that the forum may be the preferred method of communication, the real time feedback of a live technical support call would be very beneficial in this case.

Right fan noisy and capped at 2.3-2.6k rpm

Hi,
Recently, the right fan has been incredibly noisy, and it is stuck running at about 2.3k or 2.6k rpm, even if I try to run the fans higher. Only the left fan seems to run properly. The last time this happened, an SMC reset fixed it, but an SMC reset won't fix it now, no matter how many times I've tried.
http://youtu.be/d2aHEUupnmY Here's what the fan sounds like, recorded with Photo Booth.
Here's an image of trying to put the two fans at max to force the Right fan to change speeds.
This is a 2009 Macbook Pro, still running 10.6.8.

Replace the fan. it is easy to do and the costs for a replacement is not prohibitive. Look at the iFixit.com and Powerbookmedic.com web sites.
Ciao.

My brand new Envy 4-1030us model's fan is running most of the time. it is noisy and annoying.

Just bought HP Envy 4-1030us 2 days ago and i have configured my needful software. The fan seems to be running most of the time (battery or powered) and it is very noisy and annoying. I turned off the coolsense too but still noisy. Pls let me know what to do? Is it problem with the laptop. Should I return?

You can enter the BIOS and disable the "Fan Always On" setting.
I suggest leaving the coolsense on.

My Macbook Pro became noisy and slow after I reboot it. Any Help pls

I just bought my Macbook Pro last month here in Japan, and it is working well until one time I cannot login my username and password because whenever I type my username, an Arabic-like characters appear. Then using my iphone, I searched on the internet and luckily found answer to my problem. Macbook Pro users shared their same problems, and they mentioned about "rebooting" (switch on and hold Shift). then I tried it and resolved my problem.. But when I was about to use my mac, i noticed a noisy fan and my mac became slow.(which I never experiece before eventhough I have poor connection, it still run fast). And what I hate most is it always `reload/ buffer`.. A rainbow color ball always appear and it will reamin reloading for a long time.. one time, I leave it relaoding and try to cook dinner, expecting to fnish relaoding after i cook, but it didnt change, it is still relaoding (with rainbow color ball) .. What can I do with this problem? what im doing with my Mac is purely internet, movies (no downlad, just watching free movies, but not always), and manage my own site.. I hope and expect a solution from you guy.. thank you...

Try the usual things. Reset the SMC. Reset the PRAM. Repair Disk Permissions. Clear all the caches. Check the Activity Monitor to see if any processes are hogging cpu/ram. Make sure everything is up to date. Check the temperatures with a program like Temperature Monitor or iStatPro to make sure its not overheating, and to find out what speed the fans are running at.

Macbook Pro 2010 Running Slow and Pulse/Click Noise (Not Hard Drive)

Hello. My 13" Macbook Pro mid-2010 (7,1) suddenly began running slow and lagging on certain operations. There is also a light pulse/click noise coming from the center of the keyboard. I am sure this is not a failing hard drive. How, you may ask me, am I so sure??? Well, I originally thought it was a failing hard drive and so replaced the hard drive, and there was absolutely no change, and the lagging and noise still continues. This makes it very frustrating to do basic, low-memory-intensive things like browse on Safari or watch a movie.
I have upgraded to Mavericks, and have 8gb Ram. This problem started suddenly about a month after upgrading to Mavericks. In fact right now my computer is lagging just typing this, Activity Monitor says I am only using 2.75 ram of 8gb.
Steps I have taken with no resolution
-Replaced the hard drive
-Reinstalled OSX Mavericks
-Verified and Repaired Permissions (I still get a message the the following item can't be repaired "System/Library/CoreServices/RemoteManagement/ARDAgent". But I have read that this is a common thing and can be ignored.
-Restarted the computer holding down left shift-option-control and the power key for 10 seconds (not sure exactly what this resets, but some type of system cache thing.
-Reset the PVRAM stuff ( I restarted the computer holding down command-p-r. I'm not sure I did this correctly as it went to the firmware disk repair screen.
Could there be a RAM issue? Does RAM start making noise when it goes bad? I bought my upgraded ram from ebay, it isn't the official Apple Store stuff. Could replacing the ram possibly help? My System Report tells me the RAM is OK.
Putting a message on here for help is the last step before giving up. I can't do much with this computer because it is hiccupy and overall difficult.
Thanks.

WRTG54 v3 and 2.4 GHz Cordless Headset

I work from home and just purchased a 2.4 GHz cordless headset. However, I did not realize that my Router is 2.4 GHz too. My wireless connection drops every time I receive a phone call. I use a two different VOIP telephone service providers. I have installed the latest firmware with less than stellar results. Is this just a coincidence or has anyone else run up against this issue. Any suggestions

It would be a good idea if you tell everyone the brand and model number of your 2.4GHz cordless so that those who like to use 2.4GHz cordless (for whatever reason) will be able to get one that gets along fine with WiFi.

Why is the Raw processing so noisy and lousy in Aperture 3.3 vs LR4

I have been using LR4 to process my photos due to its image quality and its functions .
However I have always liked aperture for its file managmenet. when the 3.3 is out I thought
this could be me the game changer, ( I am shooting with 5D3)
However over the weekend I have found out that doing a side by side comparision the Aperture's Raw (CR2) processing
is simply not acceptable. it is lack of sharpenss and high noise is nothing but a joke if you compare to the LR4.
I hope it is some setting that I am doing wrong so I went to the apple store, and ther" Creative" guys was not able to solve
the issues as well, so now I am back to square one. I have to use LR4 to process my photos and APERTURE to store them...
Any one has better ideas?
The difference was to me day & night, it is not subtle ,,,
I hope someone can help me with my aperture issue so I can go back to using just one system.

What ISO are you shooting with?
Lightroom's noise reduction is better than Aperture's on noisy images right now. Lightroom's controls can easily knock down luminance and chroma noise, while Aperture's tools are fairly limited. You can use 3rd party plugins (Nik Dfine, Noise Ninja, etc.) that will do a good job but that renders a TIFF file which I'm not overly fond of for just this purpose.
But, still, the 5D Mark III has awfully good noise performance. Are you shooting at ISO 12800 or higher all the time? Is the noise frequently visible in all of your shots when you're not pixel peeping?
I ask because, while Lightroom is certainly better w.r.t. noise reduction than Aperture at the moment, I don't have all that many of my shots that really, really need noise reduction.

Hub4 and phone interference

Have been using Hub 4 for about two weeks and our wireless phones have been working ok. Today there is interference on the phone and when I use it it disconnects the Hub. I've read that Hub can use two frequencies my guess is these have been switched hence the phone problem. Can I manually select the Hub frequency and if so how?

Have you tried moving your phone base unit further away from the homehub?
See this link about turning off wireless on the homehub.
