Qosmio G30 buzzes when connected to a Pa System

I am using my Qosmio G30-201 laptop with my djing system. When I connect this to my mixer I get a loud buzzing sound coming through the speakers. If I disconnect the charger it stops buzzing. Is there anything I can do to stop this sound as I do need to charge my laptop while I am djing on it?

Hi
I have investigated in this forum and found two threads and discussions about similar issues.

The point is that your Qosmio and the djing system have different ground potentials and the voltage inductions in a mass loop. Maybe you could try to connect laptop to source without ground.
Or you will try the solution posted by user Thom20
Good luck buddy

External Speaker big pop/buzz when connecting or disconnecting audio cable

My external speakers make a big buzz/pop every time I connect or disconnect the stereo mini 1/8" plug into the headphone jack -- if the speakers are turned up high at the time, it's enough to blow them.
This doesn't happen with headphones - just external powered sound. If I turn the external speakers way down or off, there is no pop/buzz when connecting; muting the sound through the Macbook Pro has no effect.
This happens on all external speaker systems I've tried (including the Soundsticks currently), and regardless of whether the MB is plugged in to power or not, and with or without any other external USB or Firewire devices attached. I've also tried various cables & connectors -- always the same result. This does not happen with the same speakers on an older iMac.
I've spoken to a couple other MB owners who have the same problem.
Any way around this? It would be easy enough to turn off the external speakers next the MB every time I plug or unplug -- but with it feeding 3 stereo systems throughout the house, it's a bit much every time...
Thanks!

The problem is caused by contact made with the components of the socket as it slides into its correct position. It is a small electrical charge that bridges the plug & socket segments and not related to the current sound setting on the MBP.
I assume you like high volume from your speakers, much more than I would choose to have! I do get a slight buzz & pop myself and to my recollection always have done in 23 yrs of using computers.{quote}
With all do respect, this is not the problem here. I have the same problem as described by the thread starter, and having worked in the audio producing industry for many many years I can say with certainty that what you are describing is something else.
Sure, the traditional "high-volume-on-AMP-while-connecting-signal-source" issue is still present, as it is with any product you connect like that, but this is different: when a headphone is inserted, you can hear a clearly audible "click" followed by a very noticable humming/buzzing sound. It is almost like the machine has "fired up the audio engine" and you get to hear the idle sound.
If I play music in iTunes, stop playing, leave the headphone connected, the humming/buzzing disappears after a while, and when I press play on iTunes, the same "click/humming/buzz" is heard, even though I haven't pysically touched the connector.

New ipad has a high frequency buzz when connected to docking station.

New ipad creates a high frequency buzz/sensation when charging on the docking station and does not have buzz when connected directly to usb charger?

It is hard to be sure without seeing it, but it sounds like a bad connection to the docking port. (bad motherboard)

IMac 10.6.8, Snow Leopard with iTunes 11.0.1. loss of wifi speed when connecting a Bose Sound System via bluetooth

Hello, I have an iMac 10.6.8, Snow Leopard with iTunes 11.0.1. When connecting my Bose Sound System via bluetooth the wifi downloadspeed goes from snappy to a crawl, disconnecting the bluetooth connection, the downloadspeed goes up again. Don't have this problems with the Sound System when connecting it to my iPad. I like to mention too, that the downloadspeed of my iPad is always better than of my iMac. Are there any experiences concerning this problem? Thank you in advance.

UPDATE - PROBLEM SOLVED!!!!!!
You can thank me later - after an hour on the phone, I finally got through to a Senior Engineer.
Apperently the issues lies with GRID VIEW.
Open your Itunes, Click on TV SHOWS, then quickly change your view from GRID VIEW (Defaults to this) to List View and Viola!
We tested it out on the phone just minutes ago, my problem is solved and I suspect if you guys try this yours will be too.

An error occurred when connecting to the accounting system ID3DEV310

Hi Friends,
We are Implementing collaboration project 4.5 and want to link with project system in ECC 6.0. Both these are in the different servers.
I have done the configuration on both the servers and also maintain the RFC (ID3DEV310) in Object Links.
When I create or open the existing project I get the following error: "An error occurred when connecting to the accounting system ID3DEV310"
Costing Variant taken is PS01 (Project Planning).
Your reply would be highly appreciated.

Hi Deepak,
I have assigned the RFC destination and web server to the object type: "0WBSELEMENT" only
Also the same has been done for define Object links for accounting integration "0FIN_INT_ERP_PS"
I have entered these specific to PS objects only.

Roland UM-ONE CD-ROM does not mount on iMac OS 10.8.2 Roland driver for 10.8 installed as directed. No power ready light shows when connecting UM-ONE. System Profiler shows it, but not configured. Older UM-1X works fine. UM-ONE works on Dell Windows XP.

UM-ONE
Roland supplied CD-ROM does not mount or read by iMac OS 10.8.2, works with old TiBook and Dell laptop, however.
Got latest driver from RolandUS.com (um_1mx8d_v100), installed as directed.
No power ready light shows when connecting UM-ONE.
System Profile shows it there, but not configured.
With Audio MIDI Setup opened to MIDI Studio window, UM-ONE does not appear.
Tried many things without success. Tried swapping UM-1X (formerly on Dell laptop) with UM-ONE. UM-ONE installed and worked there without any issues. MIDI instrument communicates fine.
The UM-1X works without complaint and as expected when connected to any USB port on either the Dell or iMac, even a hub or keyboard port, just as it formerly had before changing operating systems, etc. It is old, but reliable.
Upshot is, for now, that UM-1X works with either the Dell or the iMac, but is currently attached to the iMac. UM-ONE (2011 model) only works with the Dell (Windows XP).

Same problem here! The only difference is that I'm using a MacBook pro 13 inch (2011)

MacBook Air and Pro buzz when connected to French Power

My MacBook Air and Pro laptops buzz in a pronounced way when plugged into French power sources (Martinique, Paris, Aix-en-Provence). They are American computers, and I use the adapters from the Apple World Traveler kit. Sometimes I use a regular wall adapter when I want to use the extension cord, as World Traveler doesn't allow this. The computers work fine, but I'm in French territory a lot and I worry that the buzz, which only happens when the computers are plugged in, is doing some long-term damage. I feel the buzz the most when touching the computers very lighly. Thanks~

Sounds like your adapter is not earthing properly? Change it ASAP.
Might be worth picking up a pukka French power supply if you are over here a lot too.

Qosmio G30 problems when booting up

Hi - I hope someone can help.
My G30 has developed problems on boot up. When I switch on I hear the 'tune' and the drive light flashes but the screen stays black.
I've tried leaving it for up to 10 minutes but still nothing happens. If I hold 'FN' and press f5 it bursts into life and I then scroll the various screen options and it works fine. I am not too technically gifted so be gentle with me if you have any suggestions.
I only found out about the F5 because I thought it was a screen problem so I hooked up a separate screen to try to get some access to the drives.
Any thoughts - anyone?

Hi,
just a question: do you have a picture on your external screen? I couldnt in your posting figure out if yes or not.
You can try to remove memorymodules if possible, to test if its a memory issue. (Its often the problem that one module is faulty and the reason for no-boot)
Otherwise you should bring your lovely paperweight ;) to a local service partner for hardware checkup.
Would appreciate some feedback of your diagnosis progress :)

IPod Won't Let Me Select "Folder" When Connected to my Car System

Before adding a second iPod to my iTunes I was able to connect my Nano to my car and play either Folders (CDs) or Files (songs). Now when I connect it only lets me play files. It shows the foldsers but it will not let me selct any of them. Of course it could be the car, but it strikes me as too coincidental to start only when I did a sync to add a second iPod. Any ideas? The Genius Bar suggested I check "Enable Disc Use" which I have done, but it has had no effect.
Thanks.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Go to Settings>iTunes and App Stores and sing out of account and sign back in.

No laughing... I have a Canon ZR 300 camcorder. I can not see it when connected via firewire in system profile and iMovie doesn't see it either. Any suggestions?

I have an old Canon ZR 300 camcorder that I'm trying to connect to my 17" MBP via 9 pin firewire (its a 4 pin to 9 pin cable as the MBP doesn't have a 4 pin firewire - figured it was backwards compatible). Anyhow, iMovie 09 doesn't see the camcorder. I checked under System Profile and then under Firewire and it doesn't see it either. In fact I get some red letters about not seeing firewire devices. I'm running Lion. Any help would be greatly appreciated!!

Should using mixed wifi and ethernet clients on a timecapsule work? if so is it a feature I can use out of the box so to speak?
Thanks
No a TC cannot do what you want.. it is now in dumb stupid wireless join mode.. and it turns off the ethernet ports.. in case you want to use the TC as a wireless bridge to multiple clients which is plainly wrong.. (only airport express is allowed to do this since it has only one ethernet port).
Welcome to Apple. (The plainly wrong above is a figment of Apple imagination.. of strict network protocols.. but unhelpful for a home device. maybe also to encourage sales of expresses.)

Why lower audo levels when connecting to home stereo system

I have connected an audio cable to the earphone output on the Nano.This cable has two RCA connectors that connect to the line-in of my home stereo system. It works fine except for one thing. The volume is lower than other sources that feed into a "line-in" input. To make things even across the system, is there some type of devise that will increase the output level of the headphone jack on the Nano? Or does using an Apple cable make any difference. I would think this little problem is just a case of the headphone output being of a lower output level than a "line-out" output.
Thanks for suggestions.

"I would think this little problem is just a case of the headphone output being of a lower output level than a "line-out" output."
It is, which is why many people who want to do this use the iPod dock, which has a proper 'line out' socket.

Hi Justin,
SSO logon not possible; logon tickets not activated on the server
Please check your WAS Profile Parameters in RZ11:
For enabled SSO,WAS should have the possibility to create and accept SSO-Tickets. For that the Profile Parameters should be:
login/create_sso2_ticket = 2
login/accept_sso2_ticket = 1
Regards,

When connecting to iTunes advised that the IPOD is corrupted and needs to be restored to factory settings. I executed this procedure, but after reconnecting it again identifies that it is corrupted and needs to be restored. Repeating did not resolve.

When connecting to iTunes, the system responds that the Ipod id corrupted and needs to have the factory settings restored. Factory settings are successfully installed, but response still identifies that the Ipod is corruped. Several repeats stil give the same result. Any other suggestions ?

Hello CoulntThinkOfAUser,
If you purchased the songs from the itunes store you wouldn't really loose anything. This is how to recover all of your previous purchases.
How to download past purchases.
Hope this helps.

Qosmio G30-116: How to connect the Sky Digital box to watch TV?

I just recently purchased the Qosmio G30-116 on the understanding that I can connect my Sky digital to the laptop (somehow) and watch and record sky on the laptop
* note: I am not using freeview or normal TV I am using SKY DIGITAL *
usint the supplied converter cable to connect to the video-in on the laptop (video in is like a headfone jack and the converter converts from this to female RCA)
I have plugged it into the laptop then connect a 3 RCA to SCART to it and then into the sky box, when setting up the TV section in Windows Media Centre I follow the instructions until it gets to the point where it scans for a signal, (previous to that I get asked what kind of signal I receive, I select digital but have tried all combinations,) but it doesn't find a signal.
Now I have been told that Windows Media Centre does not support Analogue input and that the connection between the sky box and the laptop is analogue.
Is this correct or not? then, while typing this I have been told by someone else that my laptop is not capable of receiveing SKY DIGITAl as it can't decode it or something. Is this also correct? If not, what am I doing wrong and can anyone help me get this going? And have I been going about this the right way or am I totally up the wrong path if laptop is capable of it?

To start qosmio player
1.switch off computer using on/off blue lit on/off button to close windows operation.
2.make sure that the computer/windows is switch off
3.Now Touch the TV icon (Blue lit button)only or the DVD player ICOn (blue lit button)only. WITHOUT USING THE USUAL ON/OFF SWITCH
4.The qosmio player/engine will switch on instantly without booting windows.
5.TV will launch within 8 seconds and the same for DVD player
6.Pres F1 or F2 for further functions such as screen size,audio,forward.rewind.pause scanning the TV channnels (auto or manual)
7.You can do the same i.e open the qosmio player/TV with the supplied Toshiba/qosmio remote pressing the Live TV button ONLY for instant TV on or DVD menu ONLY for instant DVD player/CD player on WITHOUT USING THE ON/OFF SWITCH ON THE REMOTE.That is very much similar to a standard TV remote just press the TV or dvd menu .
8.If you touch the same icon buttons i.e TV and dvd player during the standard computer usage /windows operating system,IT WILL LAUNCH THE MEDIA CENTER BY DEFAULT.that's what happen to you!
I use the remote from my bed before going to sleep and the same from bed to watch early morning TV news
Qosmio is excellent for the versatility!
Enjoy
