  • Helmet whistle after only 4 time under assistance

    Hello to everyone

    I own a Macbook Pro 17 "[start 2011]. OS X Yosemite 10.10.5

    Forgive me for the long description, but it seems that one problem has evolved into several ones and I, on my own, can not find a solution.

    On 24 February 2016, I took my computer to the title of the assistance that the battery ended of his life and had to be replaced. The hull unibody 17 "this operation cannot be performed at home as the Mac must be 'open '. For the first time, I thought to buy a battery online and replace it on my own, but to avoid "risks", I decided to take the title of assistance.

    The same day they gave me back my computer, but after a few days, the logic board failed due to a "congenital". I picked up my computer a second time and they kept there for a week to replace the logic board. Fortunately, this situation is covered by the s in warranty program that apple found that almost all the Macbook pro early 2011 had the same defects.

    Before making my computer the Apple store called telling me I could perceive the Mac, and that, because of the replaced logic edge start has a sort of a 'pause' [you see the loading bar then everything disappears and then you see it appear again]. The genius bar, I noticed that this was accompanied by a very slow start-up-in [clock] in hand, I counted three minutes.

    Struggling to help again once they told me as would have checked my computer, and during a call in the end they asked if it was possible to format as it counted by the operating system settings always "calibrated" on the old logic board.

    After the problem of formatting, reduced a bit, even if the start is still slower than before.

    I'm back from my computer, but once I used it in an environment quite I noticed that the left speaker was a whistle every time a sound that's happened. The hiss remained for 30 seconds and then disappeared. The whistling was audible, even if the volume has been completely turned off and does not appear if the headphones are connected [no hiss were audible on headphones].

    Took my computer under support the fourth time they replaced the left speaker and they said that they replaced the logic board [yet].

    I picked up my Mac and the problem seemed missing.

    So finally, we come to today, I was using my computer with headphones and I started to hear the hiss even, but this time just while I was with the helmet.

    I checked online if other people had the same problem and it seems that most of them proposed to take in respect of assistance.

    My question is: what should I do? I read on several that associated Mac forums that Apple products are "programmed" at the break after a certain period of time, if visitors are "forced" to buy a new product. My computer worked fine until I had to replace my battery, and it's the computer 17 "laptop last produced by Apple. I honestly don't know what do now that taken under help, seems it a mockery because I am sure that after replacing again thing speakers eject [maybe next time the monitor will begin to blink or light under the keyboard will fail]. I think about buying a new computer, but in all honesty, how can I trust Apple now?

    By the way I want my computer back as it was before the replacement of the battery.

    4 times in respect of aid for almost a week in less than three months is certainly unacceptable for a company like Apple like all that I heard 'experts' of the genius bar was "what you have in your hand is not only a computer, but advanced technology, etc etc..." but in the end all this "expertise" is not my problems but actually created new.

    This hissing must depend on the battery? The logic board? A faulty speaker? Another element broke during the repair? A software problem?

    This problem becomes worse and spoil the other parts of my computer?

    Forgive me for the inadequate number of questions but the problems that I encountered during the 2 months never seems to come to an end and I really hope that the community will be more useful than the genius bar, where I felt treated like a number, with the audience of store who tried to solve the problem in the minimum possible time without even listening to the end What is the problem and how I got there.

    Apologies again for the long explanation, but maybe the real problem is hidden behind something that has been neglected, and I want to make sure that nothing has been forgotten.

    Thank you in advance for the help you will surely be able to give me

    All the best

  • iPhone drains the battery faster under 9.3.1 - possible?

    Is it just me or drain the battery faster under 9.3.1 on my iPhone 6?

    It feels as if 'normal' use I make of the phone takes less time... In particular, sit and do nothing as during night.  The only thing that I have changed a few months back, it's turning off BT, I lost my helmet, but it was before 9.3.1. Its not horrible, it just feels like it lasts less time...

    Everyone with an iPhone 6 (64 GB in my case) who suffers?

  • Satellite C650-16U speakers does not work after battery ran down

    Hello

    My wife and I was watching a DVD on the computer and did not know that decision was not lit, and therefore the computer off. When we restarted it after that food was missing the sound no longer works, and I have been unable to restart. I have restarted the computer, checked all very silent buttons etc, and I have uninstalled/reinstalled the driver. When I tried using the helmet on the laptop, the sound is fine, but it does not work in normal contexts, when nothing is plugged.

    I hope someone can help!

    Thank you

    Hello

    In addition to checking the reading in Control Panel-> sound tab, you must remove the battery and unplug the AC adapter when the laptop is OFF.
    Hold down the power button / 30 sec long and then put the two parties.

  • I have a third generation and need a new battery

    I have not used for a few years and iPods are sought after by a speech therapist because music is very effective for therapy for those who need assistance with their talk.  Is it possible to challenge?  Apple can fix it as when I took it to a repair shop they told me that they would not be able to resolve that the batteries are more achievable.  Other than the battery, it is in very good condition.

    He's too old for Apple to work on it.  You may be able to find an independent electronic repair shop in your area with an Apple expert who can do the job with an Internet search.  Third party spare parts are available from the online sources, such as eBay.  This web site has repair guides

    https://www.iFixit.com/device/iPod_Shuffle_3rd_Generation

    If you can find a place that can do the replacement of the battery, do not forget that a brand new 4th gen iPod shuffle with a year warranty, new cable docking and new helmet costs $49 retail

  • Looking for a helmet system with double docks rechargeable wireless

    I am looking for a very specific product and I was wondering if anyone knows a product that will do the trick.

    I want a system of wireless headphones wireless with a loading for each helmet Bay. Transmitter should accept level line of double RCA Records. I would have preferred a 900 mhz transmitter, but IR is acceptable. The system should come with two headsets, or there should be a system with transmitter/headphones with the possibility to add a loading dock and an additional heaset.

    My old system was a Sony which is at his last breath, and I found a replacement for another manufacturer with two headsets, but it lacks the loading docks - connect the heaset in the transmitter and the two heasets cannot be pursued at the time. In addition, the manufacturer says not charging headphones for more than 24 hours or you may damage the battery.

    Anyone know if Sony or someone else does what I want?

    Hi, Verne.

    Sony factory not wireless headphones double. You can perform a search on the Internet, check for any third party double helmet.

  • VISTA and the new battery Bluetooth: no sound on headphones (Skype)

    Hello.

    I have a big problem: since I have updated Windows XP to VISTA I had to update the stack driver Bluetooth to the most recent available.
    Installation works very well. I can connect my headset is based. He said "plugged in and connected to Skype", but if I call someone, the sound always comes in my speakers and not via the headphones.

    Once, micro headphones listening, but now no longer works. I can press any button on the helmet, chance anything in the Options of Skyp... Nothing.
    With the old battery on XP the helmet has recognized as a Windows Audio device. He's not with the new battery. In Device Manager, two Bluetooth Audio devices are branded 'problem - driver issue '.

    I wish I could just use the old battery under Vista, but it does not work (not compatible with Vista).

    I really need help, SOON because I used to do all my calls through Skype Out.

    Greetings, your Tim

    You have a stereo headset or a monoheadset? What audio drivers have a conflict - bluetooth audio only or also audio system drivers?

  • Battery problems and speaker

    I have two concerns with my Toshiba NB200 netbook / 00 Q.

    1. the battery

    I always on the use of all the power connected to the AC. When I finished I turn off my computer and when I'm sure it's out I have unplug the AC plug and put away the computer. When I restart the computer I first connect the AC plug and then turn the computer back on, but the battery is always red and "load". Is this a bad battery? Why is it loads if its only source was AC? Specifically, I make sure I have press 'closed' and not hibernate or stand-by.

    2. speakers

    Does anyone else have this problem where, without a helmet, speakers tend to seem stronger on the right and it is very difficult to hear whatever it is on the left. I checked the realtek and volume settings, but the speakers are "centered". any help is appreciated.

    1. it will be certainly charging because he will have lost a few percentage points of full load (at least) depending on how long it has been turned off. If you have some things turned on in the BIOS as the sleep and Charge, then he will lose even more power.

    If you very well use only on AC so you should disconnect the battery completely and only connect the battery up to keep that it loaded somewhere between 40% and 60% of full load. This will prolong the life of your battery.

    I would first determine how much battery is being sold out in 24 hours when it is off, and then we can see if there is anything that can be done to reduce this amount.

  • Is my phone battery?

    My 3 year old e260 sansa 4 GB suddenly started cutting around a year ago. The problem was not really that bad it first because he didn't do it very often, just occasionally, so I has not paid it any mind.

    Last night when I turned on my sansa, it would close whenever I pressed the button play, or tried to open 'my music '. It works fine when I plug it on my charger, but once that I take it off the beginning of problems once again, even at full power.

    Should I just get a new player? Or is this fixable problem?

    If the load circuit does not work, it means the battery might be good, but the player is not just load it.  If the battery is faulty (not / hold a charge), then the result is basically the same - dead battery.  The only way I can think to test with a known good battery (or, Alternatively, test your battery to a well-known player).

    You can buy a new battery for not a lot of cash, but as prices fall on these players I think it becomes less advisable to buy spare batteries make more sense to just buy the whole player.  For example, there was an e250 renovated on woot.com one day or 2 there are something like $23.99 shipped.  If a battery will cost more than half a lot delivered...  I don't know, maybe I'm just too much of a bookworm electronic pack, but you never know when some of those spare parts could come in handy.  If you have lost a button, for example, or if you cracked the front plate (but not the internal LCD screen), or if your internal flash drive went wrong (and if both players are v1 models), or if you lost a part of the small screws on the back of the player, well, you get the picture.  There are a few interchangeable parts that can be useful.  Unfortunately, the elements are not replaceable (taken from helmet and LCDs).

  • Latitude E7440 - sound does not come with a helmet

    Hello world

    I have a laptop Dell Latitude E7440 8.1 Windows running. I had problems with no sound coming with headphones plugged in the headphone jack (its only comes through the built-in Laptop speakers). I tried several fixes including:

    -Definition of headset as default playback device (my laptop groups speakers and headphones together, is not possible to choose one over the other).

    -Remove the battery, now hold the power for 30 seconds, turn it back on

    -Update Realtek Audio driver

    -Uninstall the Realtek Audio driver (and deletion of files), and then restart the computer for the native audio driver is used.

    I had the most success with the help of the native audio driver (after deleting and uninstalling Realtek). However, when I do this, I have from both headphones and speakers of the laptop. This will work for a day or two, then I'll start to have no sound from the headset again (despite running the native audio driver).

    I don't know if it's a hardware or a software problem. I don't think it's a hardware problem, since I am able to get the headset to some working hours. Are there new ideas or advice? I'm debating getting a USB adapter for my helmet, but I don't know which would solve the problem if it's a software problem.

    Thanks for the help in advance!

    I'm debating getting a USB adapter for my helmet, but I don't know which would solve the problem if it's a software problem.

    The usb sockets are very expensive and me would be worth the risk that it might not work. You could test the hardware failure (or repair the software if it's a software problem) by resetting the laptop back to the factory setting original, but for many people it is worth some money to try and avoid would do that.

    Usually when the headphones are not detected by the driver from Realtek but are when you use the native driver, the solution is to completely remove the software Realtek, the way you did and then install an earlier version of the Realtek driver. However, it is difficult to understand the symptoms of your laptop. Normally if there is the same symptom with pilot of the provider and the native driver, which is strongly evocative of hardware failure because both pilots are not likely to have the same bug at the same time. In your case, but I wouldn't bet on it anyway.

  • Indicator of edge battery blackBerry Smartphones and Bluetooth problems

    The Priv is about 5 days old and has new updates are installed en all apps. The carrier is Rogers

    When I first turned it on the edge of the battery indicator came and it showed the power level and the percentage of the charge. Who has stopped working and then the "light strip" edge now works after a reboot from last night.

    The edge lights and stays on for about 5 seconds and then turns off then that plugged. There was an indicator that identified the percentage of charge and I think that the time to full charge. These details will no longer appear.

    Just rebooted it and then reconnected it and edge came to light on, stayed on about 5 seconds, then * beep * down. indicator % etc. came not

    Indicative on-board battery is turned on and ambient display is on

    Last night when he was in charge and I held it in my hand the edge of the battery light up and then turns off. If the Palm of my hand touched the lower right edge lighting turns off and then it shuts down when I moved my hand. When I placed my hand there once again he started. Connection loose?

    Bluetooth. When calls come sometimes in bluetooth works. If I turn my helmet a couple of times it works. Shouting works, but the call is maybe 25%.

    The listener a Plantronics traveler edge worked flawlessly with my old Q10 if this is not the headset.

    Hello

    The battery charge indicator will disappear if the phone is in a dark place. If you turn on the light in the room or even shine a flashlight on the sensor just below the listener, you will see the battery charge indicator again. It has nothing to do with you keeping the device or not.

    It was reported on misconduct... weather Bluetooth that connects to the listener or the car. A software update its in the works earlier this month (June). I can't tell if that delivers its treaties or not since I am not fully aware at the moment, what this update will correct or improve.

  • Accidentally plugged usb battery. Its now on Audio jacks are dead

    Hey guys,.

    Today, I have a battery of Vapir NO2 and noticed that he had the same charger as my mobile phone. I thought to myself, "well lets see if it charges it! ' and connected quickly and immediately recalls batteries should never be placed in a usb port on a computer.

    -USB can still transfer files

    -taken audio upper panel seem to be only records not

    -taken back panel audio record on the computer but don't play no sound

    -When you attempt to play sounds through sockets audio back panel, it sounds like the puffs of air out instead of sounds so that made me assume that I can have blown some sort of Cap on my motherboard, but I can't find.

  • Helmet of being odd blackBerry Smartphones

    I tried to plug in headphones Skullcandy FMJ in my Pearl Flip and she had the right channel sound. However, when he plugged his to halfway comes from two channels but with a steep slope buzz.

    (The Skullcandy Full Metal jackets are the standard, not the iPhone/Blackberry compatible with the microphone online.)

    Someone had that happen with other headphones?

    I tried battery pull without success.

    Second series of helmet later and same question... My handsfree stereo Blackberry game is at home so I can't test all the way to my dorm.

    I also cleaned up the output port so I don't think that should be a problem either.

    Help, please! I miss using my Blackberry as a music player!

    The intuition that a few people had on PinStack is that the helmet was probably damaged and they are right...

    I managed to swap with my provider to another and the new works very well!

  • Alerts of Smartphones blackBerry replay only stereo BT, when the helmet is on

    Hey has any who ever encountered this problem? I have a blackberry storm 4.7.0.148 and use BT stereo Motorola Rokr

    Anytime by the helmet, if I got a call, sms or email... the alert would play directly from the phone and not in the earpiece of the headphones. Since I upgraded my desktop 5.0 and fact Manager initial sync... now all my alerts play headset earpiece and phone gives no audio signal for alerts?

    I could appreciate this feature if there was a way to toggle it on and off but I can't find anything. I want the audio to come back to my phone... and not hear my ringtones in my earpiece... It also constantly drains my battery from the headset, as it is always on now.

    Guess I have solved my problem... After playing with the bluetooth options, I had to disable profile for the audio source services. The only problem with this, is now, it will not play music or movies via the headphones when I want to.

    I hope an update will fix this option to determine when to use as audio source
