Turning on Red Lights on the HP-Envy 17 3D-3090nr Monitor

Hi,
I was hoping someone could explain how the stereoscopic 3D lights (i.e. the 2 red lights on either side of the webcam) that drive the active shutter glasses work?
I recently installed Elemenatry OS Linux (based on Ubuntu) and noticed the lights get turned off when it boots. Windows 7 on the other hand automatically turns them on during boot and they stay on even after a reboot. Everything else works perfectly well enough, the 3D is the last piece of the puzzel.
I have desktop with the exact same dual boot setup but as a 3D monitor I use the Sony PS3 3D Display which works in a similar way to the monitor on the Envy-17 3D. However, on the PS3 display there is a button that one can use to manually activate the lights.
I am wondering if there is a way to turn the lights on manually on the Envy-17 display rather than dynamically as it currently is?
Is there a driver that I can apply with ndiswrapper or something to manually turn the lights on?
It doesn't seem to be a graphic card driver related issue and experience with Windows on the desktop has shown me that the auto-dectection doesn't always work.
Thanks in advance

PoPlease help me, I tried everything.

I've got a mac pro problem with the starting up, but also a red light on the logic board solidly on. Its not among the diagnostic led. It's located near the BT adapter and the front fans. Also the fans run loud also. any solutions?

Hi
I've got a mac pro late 2006, and i am having problem with it for quite a while now. the problem i am facing is the start up process, and the red light on the logic board. Earlier I've got the two led on the diagnostic leds 5 and 6 turned on without the diagnostic button being pressed, and i think those are related to the processors overtemp. I've managed to solve that by, removing the processors and re applying the thermal compound on the heatsink. what i have left now with is the red light on the logic board at the time i plugged in the power. At the same time when this light come on, the power indicator at the front panel come on as well. i am not sure what is this light relates to. We've replace the power supply too, and gone through the SMC reset but seems no help.
Any idea on the problem? I am desperate about it, and i will be greatful if anyone can help..
thanks and hope for your best solutions

I can't help directly with your problem but you might check here http://tim.id.au/laptops/apple/macpro/ for a service manual which could answer your question.

No sound on my mac book and a red light in the headphone jack

as in the title,
The sound controls dont work and I have a constant red light out of the earphone jack, with the earphones in all is okay but without ....silence

The red light is the digital in light, that is how it reads the headphone jack. The reason the sound doesn't work is because a switch to turn the speakers back on is stuck (note that if you boot the computer, you will hear the startup tone).
There are several ways to fix this...
Some have found that putting the headphone plug in and out several times (maybe twisting it a little) will work.
Others have used a toothpick to adjust the switch (I don't advise this because the toothpick may break).
Instead of a toothpick, many have used a paperclip (probably best to use an insulated one). I couldn't get this to work, but I would suggest straightening, folding in half, then twisting the paperclip and moving it around in the port.
You can also use a sewing pen/needle.
I have seen all of these methods online, but they didn't work for me. I took a que from this instrucable and cleaned my jack with a dry q-tip. I then cut off most of the end and turned it around inside the port. This worked, but after I put the headphones back in the same problem came up, I just did the same procedure again and it worked again (even after I plugged the headphones back in and took them out).
PS: I woud suggest putting some q-tips and possibly some scissors in your MacBook bag in case the problem arises on the move.

Red light to the left of the receiver of the iPhone 5

I had my iPhone 5 replaced at the weekend for a speaker issue, but I noticed today when using the replacement in a dark room, I can see a glowing red light to the left of the receiver. I did a search, of course, which brought up results concerning the iPhone 4 and that it's the proximity sensor and not something to worry about. But I also saw this "eHow" article that says it's because the phone's been exposed to water:
http://www.ehow.com/info_8704998_red-light-iphone-mean.html
Earlier today I was using the phone when it started raining, so I quickly wiped it against my sweater and put it in my inside jacket pocket. I didn't think that would be enough to cause any damage to the phone and the phone is working fine, but now I'm a bit worried, having not noticed the light before.
Is the eHow article wrong or do I have a reason to be worried?
Thanks in advance for any help.

That's one of the most absurd things I've ever read...the light is part of the proximity sensor. The sensor is an infrared light that can appear red when viewed through the front glass in a very specific way in the dark (the glass distorts the infrared light enough to make it very weakly visible). This is totally normal and nothing to worry about. The water sensors are round white stickers in certain locations on and in the iPhone. When they get wet they turn red and do NOT turn back. The sensors wouldn't be very useful if they changed back when the phone dried...

I have a MacBook Pro. My mac can detect wifi. But will not connect. I did get connected vis TCP/IP settings but I can't connect to any wifi anywhere. Network diagnostic has a green light for wi-fi and wi-fi settings. Red light for the rest.

Hello NotAppleSavy,
Thanks for the question. After reviewing your post, it sounds like the computer wont connect to networks. I see you have used network diagnostic. I would recommend that you read this article, there are a lot of other things you can do in this article that may be able to help you resolve or isolate the issue.

Red lights behind the power button

In reading through some posts last night I got the impression that I should be paying more attention to the lights inside the box, behind the power button, when booting (or I should say attempting to boot) my dual-core G5 PowerMac.
My observations this morning are that I see a big red light when the machine is first powered up from cold, and also when it is restarted. That goes off. A few seconds later, before the chime, I see a brief, much smaller red light flash in that same area. Almost a pinpoint.
Is that normal, or is it diagnostically significant?
(As noted in my earlier post today, I'm launching a final effort to fix this sick puppy before I give up and take it down to the Apple Store, but it needs to be a campaign of controlled baby steps.)
TIA,
Kathi

Hmm, on second thought I'm not so sure... but I don't have time to open the thing up right now and figure out exactly where each of those LEDs is. The drawings in that article and in my manual aren't terribly helpful.

My speakers on my macbook receiently quit working after I had been using some headphones. My headphones still work whenever I plug them in with both increase and decrease in volume. I have also noticed a red light on the inside of the headphone jack.

My speakers on my macbook pro quit working the other day after using my headphones. when I try to adjust the speakers my screen indicator sayes that it is at full volume on the bar but also muted(circle with line through it). I also noticed a red light inside my headphone jack. My headphones still work including volume. Any quick fix?

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Make sure Mute is not enabled.
2. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. Reset SMC.     http://support.apple.com/kb/HT3964

Why does my iPhone 5c have a red light on the top of it

my iPhone 5c has a red light on the top of it next to the speaker but it is only visible at night, it's really scary

It's the proximity sensor.

Iphone 4 dead, red light above the speaker

hey, my iphone suddenly died yesterday. i was texting, browsing normally and couple of minutes later it was dead (battery was almost full). i tried hard reseting it, connecting it to my mba and nothing, itunes doesnt even recognize it. couple of hours later i saw this red light above the speaker and after some googleing i found this discussion
https://discussions.apple.com/message/16706124#16706124
where it says that the red light means my iphone was damaged by water. the only thing i dont get here is HOW since i havent dropped it, nor used it outside in the rain haha. i am kind of confused because i dont know if its dead or not. right now it's resting in a zip bag full of rice but i dont get it. could someone help me? thanx
i mean, its an iphone 4, ive been using it for years and this is the first time this happens, battery works great, phone works great i dont wanna change it. the only good thing is that it's helping with my addiction to internet hahhaa, first 20hours were baaaaad. thank you

Hey there lildl110,
Let's get that iPhone 4 to cool down. It sounds like the phone overheated and needed a bit of a rest. Is it still too hot to touch? If you've given it some time to cool down please try the restart method,http://vz.to/1ciOvXw.

Getting red light on the audio port

Hi, im not able to get sound on my macbook, ive tried using a headphone, and it works fine, but as soon as i plug out the audio jack, i see a red light on the audio port, and the sound icon is grayed out...
I've read similar problems on the forum, but could not get a resolution, can someone help me out with the correct resolution of this problem????

the toggle switch inside the audio jack it flipped the wrong way, so your mac still thinks your headphones are still plugged in. Try to rapidly insert and remove the headphone jack in and out of the port to toggle the switch back.

Xperia S does not turn on, red light when charging.

My phone, after spending a day on a boat, was low on battery (this was 2 hours after leaving on the drive home). It went from 6% battery to shutting down completely in a matter of seconds. I plugged it into my car charger immediately, but it has not turned on since. Previously i have had problems with the headphone jack not recognising if earphones were plugged in or not, but this usually resolved within a few minutes. On top of this i have once struggled to turn the phone on due to i believe a once off problem with the power button.
Recently the headphone jack has been playing up a lot more than usual, but it never resulted in this. I have never experienced any other problem with the phone. PROBLEM: Once it turned off, I have been unable to restart my phone. When charging it shows a dull red light like when charging less than 15% battery. I have charged it now, on and off using multiple different charges for 6 hours, and have left it on its original charger as i write this. The power button plus volume up has no effect. There is no vibrations when i turn on the device. The screen which usually loads something when charging, has not displayed anything since turning off. It does not connect to either an apple or windows computer with a usb cable, volume down key depressed or not. It does not get hot to touch while charging, and i remember according to AVG that the battery quality that day was "good". After 6 hours of charging, the red light is still there(and usually a full charge after 1.3 hours, leaves a green light) Put simply, the only responce of any kind i get from the phone is a red light when charging. What have i done? recharged the phone for 6 hours, tried power button, restart button combo, usb connection with both an apple and windows computer, i also put it in rice in case there was any water but did not change anything. anything changed? after 2 hours of charging on the wall, the red light disapeared... tried the above, nothing happened, unplugged the phone then replugged it in... red light. I will try to get it repaired shortly along with a broken PS3, but i would rather a solution, as both my work and social life heavily depend on it. thankyou in advance

If you have given it a good charge and still have no luck, I would advise running a software repair. This can be done with the phone powered off:
1. Download the PC Companion software from http://www.sonymobile.com/gb/tools/pc-companion/
and install it on your PC.
2. Install and open PC Companion then select Support Zone.
3. Phone Software Update.
4. Start.
5. Repair Phone
6. Continue
7. Accept data removal
8. Next
9. Wait for prepare
10. Select Phone
11. Follow the connection steps

Is it dangerous to look at the red light in the headphone jack?

I recently purchased an early 2009 model white MacBook. Today I was installing Windows on it and I noticed a red light coming out of the headphone jack. I thought there must be an LED in there to help you locate it in the dark. I was curious about it so I crouched down next to the computer and looked inside the jack to see what the deal was.
At the time I didn't know that there is such a thing as an optical audio jack. Obviously I now know that's what the red light was all about. Now I'm wondering if looking at that light could have injured my eyes. Is it a laser, an LED, or something else? Does anyone know how dangerous it is to look at that light? I looked directly at it from close range for perhaps 3-10 seconds, with eyeglasses on. I don't remember it seeming uncomfortable to look at.

Thank you both for your replies.

To the best of my knowledge, that light shouldn't be on when the port is empty.
Yes, my understanding is that that light should only ever come on when there is a Toslink mini-plug adapter inserted into it (or at least a regular 3.5mm analog plug). However, like you said, I've seen a number of posts on the internet about that switch that turns on the digital output (red light) getting stuck in the on position (even without having plugged in a Toslink adapter). My understanding is that in my case the light came on because I was in the process of installing Windows and the driver for the audio hardware hadn't been installed yet.

As far as harmful rays, I doubt that it would be harmful because I've read about this audio problem before but never with a cornea damage attached to it.
I did look inside the jack directly at the light. I think it might be the retina that would be at risk if anything, but in any case, I sure hope nothing was damaged.

The power for the lasers used for digital audio is very low.
Is it a laser?
JoeyR wrote:
Especially if you didn't find it uncomfortably bright.
I don't recall having a reaction that it was uncomfortably bright and then having to force myself to look at it. If it had seemed uncomfortable I don't think I would have continued to look at it.
I don't think I actually became concerned about it until I found out that the light is for digital audio output and wondered if it is a laser. Not that I recommend looking right at a bright LED either. But I wasn't expecting a bright LED either (let alone a laser) -- like I said, my first thought was that there must be an LED inside to make the jack easy to locate in the dark (I was in a darkened room at the time.

If you've ever, even very briefly, had a low power laser pointer hit your eye, you'd realize it is super bright.
Fortunately I haven't, but someone who did have a laser pointer aimed at their eye told me they noticed it when they felt a burning sensation on their eye.

Any damage would almost always be nearly immediate. If you haven't had a problem, you're fine.
Do you think any damage would be readily apparent right away, in the form of pronounced discomfort or noticeable vision problem?

My BB Curve will not turn on; red light blinking

My bb curve 8330 will not turn on, charge, or do anything other than flash the red light at me. I tried removing the battery and have tried charging it, but nothing seems to help. Any ideas?

Nevermind, I resolved the issue by removing my memory card.
