Wifi/sound/screen failure

Hi,
when i booted my comp today (hp dv6 1338ca), after i chose the user to log into, the screen became darker (process occurs after each restart/shutdown/unplug ac and battery and press on the power for 30 sec) before i logged in (in the stage of writing the pass), sound doesnt work (red on the computer panel), wifi doesnt work (even though it is blue on the panel), and win7's start looks different (like the old win versions).
Any idea why / how to fix it?

Hi @egilad86
Welcome to the HP Support Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I saw your post regarding the myriad problem you are having with the dv6. From what you have described it sounds like it might be a hardware issue with the wifi, screen and sound all going. Here is an HP document Testing for Hardware Failures there is a section on using the HP UEFI Diagnostic Tools. Run the System Test – Extensive Test to check practically everything.
I would also advise using the System File Checker tool because these issues could also be connected by a problem in the operating system. This tool will scan your operating system for corruptions.

Kernel Panic & Screen Failures

I've just had two identical failures in one day on two separate Powerbook G4's running Tiger. There was a kernel panic while playing World of Warcraft, and now the computers' screens cannot be activated. I hear the hard drives spinning, but the screen never comes on. The Apple light on the back of the lid does not light up, the sleep light does not work - in fact, the sleep function does not seem to kick in when the lid is closed.
My wife's G4 failed yesterday. She was playing WoW, and she reported several kernel panics. Finally her machine failed to boot correctly at all.
Today, I tried to get it working, employing all the usual methods. I suspected some type of hardware failure. We gave up, she pulled out her old iBook and I played a little WoW on my G4. While simply checking my in-game mail, I got a freeze/kernel panic. I rebooted and the screen stayed blank - precisely the same symptoms as hers.
These are identical 12" Powerbook G4 1.3 GHz models with 867 RAM (factory-installed) in each. We're on an Airport network and in separate rooms, and not plugged into the same power source.
I reset PRAM, reset the Power Manager - no luck.
I get startup chimes (even the second chime for the PRAM reset) and I can hear the drive working. The system is coming up, but the screens and lights are not working for some reason.
I can boot the machines into Target Disk mode and access the hard drives via this iBook, so the system seems intact. On the affected machines, I can press the Volume up/down keys and hear the audio sound cues. Brightness keys have no effect.
It would really seem to be a Power Manager issue, as if no power is reaching the screen or anything in the lid. I reset the Power manager to no avail....
Two screen failures on identical machines under the same circumstances less than 12 hours apart? That's one heck of a coincidence... is anyone aware of a known issue similar to this?
Powerbook G4 12" Mac OS X (10.4.6)

No, this is not it.
I too today expienced a Kernel Panic while playing WoW. This only happened before about 4 or 5 freezes within the game which ended up having to be reset with the powerbutton pressed for 10secs.
This happened, as I said, about 4 or 5 times, while connected to external monitor and without. This has only ever happened to me today. I reinstalled WoW. Nothing. I thought it was a temperature overheat so monitored the temperature with iPulse, it heated to 55.3 degrees celcius, one fan kicked in and it crashed.
I then used GioFX's HD 3d screensaver.
The computer crashed within minutes. What causes these crashes?! It is something to do with the GPU's 3d rendering, but I can't see why it happened today... the only thing I can think of is heat damage, it has been hot the past few days (30 degrees and more ambient temperature) and the laptop's fans have been working full tilt for 2, 3 hours and more while I play.
I am lucky, as my PB is able to be used (as long as no graphics are intense) but it is, in effect broken.
I need a response quickly, my guarantee with the seller is running out soon, do I need a GPU replacement or don't I?
This happened while playing World Of Warcraft 1.11.2(5464) and attached to an external monitor, keyboard and mouse.

IMac Screen Failure

Hey,
I was just wondering if any of you are experiencing screen failures as noted in the link below? If so, is it the aluminum iMacs, or is it the white ones?
http://www.macnn.com/articles/07/11/30/imac.screen.failure/
Thanks!!

Hi autiger
Which iMac do you have and are you having any display issues?
I don't believe it can be jinxed, so I'll do a little bragging here. My 17" Early Core Duo w/Apple Care purchased Jan. 21 2006 is great and has no gradient light/dark, no dead pixels and only a very very small backlight bleed. The sRGB and Adobe RGB (1998) profiles were OK, but the display seamed a little washed out. After more than a few tries, and some good advice from Barbara B and others here I was able to set a new profile that is much richer than any of the factory supplied profiles.
All display manufactures and computer system will have there share of issues, some more that others. I have had more than a few Apple's over the last 20+ years without a single hardware problem. I do have to admit though, that with the all-in-one Intel I bought Apple Care for the first time ever???

Ipad screen failure

My bought my Ipad 15 months ago (Ipad New) and has recently started a tendency for the screen to suddenly flicker, a bit like an old TV which loses vertical hold only much more rapid. I can turn the device off by holding down the usual power down buttons and things start off again normally but the problem is appearing with increasing frequency. This problem has appeared since I upgraded to the new IOS 7 about 10 days ago. Does anyone have a solution to this other than replacement?

My iPad does this sometimes, have you dropped it before?
Anyway, to get rid of this screen failure you take your iPad case off if you have one on and smack the back of your iPad.
It may seen that you're doing harm but you're actually fixing the glitch!

How do i get rid of the annoying wifi connect screen whenever i am in a mall, it pops up even though i have cancelled it many times and revert to 3g

how do i get rid of the annoying wifi connect screen, even after i have rejected and cancelled using it and revert to 3g?

Actually just turn off "Ask to join networks". Settings -> Wi-Fi -> Ask to Join Networks. This way your wi-fi will still work at home or anywhere that you want to use it but you won't get prompted to join unknown networks.

X-Fi sound channel failure.

X-Fi sound channel failure. I am currently using an X-Fi XtremeMusic PCI card on a 5. speaker system. Sound is not correctly generating on the all speaker channels. When I first started having this issue, the front right channel stopped generating sound through the X-Fi software. Channel tests would produce sound on all the other speakers. However, while playing music or a game, sound could faintly be heard on the front right channel. Setting the speaker options to use head phones instead of 5. speakers would work fine, but would not generate sound properly for the front right channel under any other configuration. I have double checked all the connections and the speaker unit and they are all set up and functioning correctly. Switching between Entertainment mode and Game mode did not seem to fix or alter the issue.
I? uninstalled and reinstalled the drivers with the latest driver (2.8.008). All the speaker channels started working again when I did a quick channel test. However, once I adjusted the volume control to 00%, the rear left, rear right, center and subwoofer channels all died. The headphone setting still works as expected, and switching between any other speaker settings did not otherwise change the results. Switching from Game mode to Entertainment mode did cause a new quirk though. The channel test labeled the front left speaker correctly, but sent the front center sound to the front right speaker and from there no other channels responded.
So right now I am trying to determine weather this is a software issue or a hardware issue. If its just hardware, I can solve that problem by getting a new card. If its software, obviously getting a new card (same/similar model) is not a sure fix, but fixing the software issue would save me from buying new hardware.
I am running Windows XP SP3 on an AMD Phenom 3x 8750, nForce 750a chipset and a Gforce 9600 GT. The X-Fi card is the only addon device on the PCI bus.

Re: X-Fi sound channel failure.e How? Are there instruction on how to do that?
What I've done so far is use the Creative Diagnostic to test everything to make sure it is working properly. It says it is. I checked the Device Manager, and everything seems to check out there also.
I think something might be missing. When I tried to download the lastest version of Creative Diagnostics, everything seems to be just fine, until the very end. That's when this message comes up? "Setup did not detect the required components. Setup will exit." Then when I checked to see if anything was interfering with the Creative software, a yellow question mark does show up, but not by or in the Creative part. It is 2 spots above, and says "Other Devices--Audio Device on High Definition Audio Bus"
What could be missing though? I still have the Creative CD to download everything. I've tried that, but still, that yellow ? comes up and says? "Setup did not detect the required components. Setup will exit."? Shouldn't everything be in that CD!? It always worked before.

Can I keep iOS 7 from turning off my Wifi when screen locks

No. The Wi-Fi auto-shutoff is meant to be a means to conserve battery life.

Macbook Air 11" 2012 screen failure?

Wondering how many others have had problems with screen failure on this particular model? I purchased march of 2012. I read elswhere that they were having issues with displays that were not Samsung brand. I just had to pay to replace at 16 months; 6 months of of which no use. I am not a high user of machine. I was really disappointed with the attitude of "oh well you did not buy the extended warranty?"

Bluetooth keyboard not working when prompted for wifi splash screen io7

I just upgraded to IO7 on my ipad and I use the apple bluetooth keyboard. However, when the WiFi splash screen appear to login using say Cisco's login the keyboard does not work. Meaning it does not accept keystrokes. Because the keyboard is paired there is no way to show the normal onscreen keyboard unless you unpair.
My work around has been to dismiss the splash screen and open up safari then try to hit a website which then produces the splash screen within the browser. Then I'm able to use the keyboard again. Anyone had the same issue and is there a work around as this is highly annoying.

Thank for showing interest in my situation and trying to answer, however yes...
FROM ABOVE: "Attempting to repair the keyboard accomplished nothing, however I did learn that when prompted to enter the bluetooth 4 digit code for pairing the keyboard was able to send the 4 numerical digits and striking the return key did succesfully pair the keyboard to the iPad again."
I'm going to try "Forgetting the Device", turning off the Bluetooth Keyboard, Turning off the iPad 2 iOS7, Turning the iPad 2 iOS7 back on, Turning the Bluetooth Keyboard back on, then setting it up via the Bluetooth menu again. Doubt turning off the iPad will accomplish much, but it will be good to have it scratched off the list.

- 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.
- Then go to Settings>iCloud>Storage and Backup and either turn off iCloud backup or backup to iCloud

X220t bizarre screen failure question

Just yesterday after a reboot my screen on my x220t tablet (with windows 8 installed) stopped dispaying anything. Right now I have it hooked to my HDTV through the display port. But here is where it gets weird:
The laptop panel backlight stil functions and I can use the blue function keys to raise or lower the backlight brightness.
The wireless and HDD access icons on the bottom of the panels bezel still function.
the touchscreen itself still functions.
Like I mentioned above the display port still functions.
I'm guessing the panel itself has died or the connection between the panel and the MB/laptop itself has failed.
Right now I'm trying to figure out where to start and what the most likely failure is before I crack it open. I've got experience fixing IBM, Dell, HP, and a few other brands of laptops so I'm not worried about not being able to fix it myself, the main thing I need to do first is try and iron out what has failed so I don't have to take shots in the dark with which components to replace.
If anyone has any suggestions I would very much appreciate them!!

Do you have a warranty? Usually, unplugged cable yields a white screen. Yours sounds like a failed panel

2.5 Problems - SOUND and FAILURE to Connect to Email and Weather

Hello, The upgrade didn't make a difference - the Sound on my iPhone is WAY too low. I cannot use it in a city, period. (must use a headset - I've never had a cellphone that required a headset in moderate noise atmospheres). The Speakerphone is profoundly weak - it may as well not exist. Literally it sounds like a regular cell phone NOT on speaker but turned up 3/4 volume. I had several cell phones that were naturally loud like that. I sure miss that feature.
What is the DEFINITIVE solution for this? I've been away and reckon there MUST be a Famous Apple Solution by now?
MAIL CONNECT FAILURE - most often at Home (NO Cell signal; Wireless signal from Linksys access point) but very often wherever I am, when I click the mail button, NOTHING happens except the status says 'connecting' for a while then stops and the notes read 'last updated [3 hours ago]' That is, last updated 'time' from my LAST successful email update several hours ago, but NOT from any current download. I shut down, try again - nothing seems to work and the Mail will act this way in what seems an arbitrary amount of time/failures (sometimes overnight) then it will behave as designed - connect and download when I click on Mail button.
The SAME THING (periodic, arbitrary Failure to Connect) happens with the Weather, except with the Weather the status reads 'updating...' for a bit, then states 'update failed'. Remember, this happens at home (WiFi) AND when I'm in Public (EDGE AND WiFi) and is seemingly arbitrary. (I'm pretty sure it happens with Stocks as well, but I'm not trying as often...)

There was no update on 10/26 nor has there been any update for a number of weeks.
My check update currently says 11/1/07 but that merely means that iTunes will automatically check on that date. It does not indicate that there will be an update.
You can always check by manually depressing the 'Check for Update' button on the iTunes info page. That will tell you whether your current firmware is the most recent version and what the version number is.

Ubuntu 13.10 on a T440 - Wifi, Sound, Fingerprint reader and TrackPoint issues

I recently got my t440 and put Ubuntu 13.10 on it and have had a few problems pop up. Hopefully someone here can help, or I will find solutions and post here as things get working again.
Wifi - I have a Thinkpad 11b/g/n 2x2 wireless card. I do not believe there are currently Linux drivers provided for this card. According to thinkwiki, the 1x2 version of the card works with real tek's rtl8192se driver; I have tried to load it with modprobe, but it does not work for this card. There might be a solution to this with ndiswrapper, but I haven't been successful. I have ordered an intel wireless card to replace this one.

Fingerprint reader - All previous thinkpads had AuthenTec fingerprint readers; this generation ships with Validity readers. Info on thinkwiki is describes installing fprint, but fprint does not recognize the validity reader. This post looks promising.

TrackPoint - The trackpoint pointer works fine, but lenovo did away with the physical left/middle/right click buttons. The top on the touchpad can be pressed (in windows) for left/middle/right click, but I haven't gotten this functionality enabled in Ubuntu yet. Might be able to fix this in the xorg.conf file

Fingerprint reader- above links do not resolve the problem. fprintd and frprint-demo do not recognize the Validity fingerprint sensor. My issues are the same as described in this post.
