My DV5220US laptop causes TV interference. Why?

I watch TV on a set of "rabbit ears", I can't watch it at all if the computer is on - the signal goes completely dead. It does not matter if I have the built-in wireless turned on or off, or whether the battery charger is plugged in or not. I can't even use he Hauppauge USB ATSC-01 tv tuner I' got for traveling, with it's built-in antenna or an amplified USB-powered antenna, or the "rabbit ears" (which are also amplified).
What gives???

I have the same problem with my hp notebook. I cannot watch TV unless the notebook is away from the antenna. I have an omnidirectional antenna. The interference makes it not possible to watch channel 13 since the signal of other channels is very strong.
I may look into contacting FCC (Federal Communication Commission) about this apparent deficiency of the hp product.

HDMI cable/adapter causing feedback interference in studio monitors

Hi I just bought an HDMI cable/adapter to connect my MacBook Pro to my LCD tv and as soon as I connect my studio monitors through my MBox interface, I got really loud CPU feedback through my monitors. Any suggestions? really trying to have a nice studio set up here lol

Thanks for trying to help me out, rsannie. I had actually figured it out earlier, didn't get a chance to post. Under Sound, click Recording tab, click the device, click Properties, click Advanced tab, uncheck Enable audio enhancements. This was what was causing the interference/feedback type noise.
Just for the heck of it, to get better acquainted with the settings, I went to where you suggested but could not toggle that feature on/off. This feature looks like it deals with the external mic (the ones by the webcam) and not from a source fed through the minijack anyway.

I am suffering the overheating issue in my HP Pavilion DV2000 laptop caused by NVIDIA GPU issue.

I am suffering the overheating issue in my HP Pavilion DV2000 laptop caused by NVIDIA GPU issue. When I go to the settlement site http://www.nvidiasettlement.com , I see that the last date of filing the claim expired which was 14th of March 2011. Is there any option remaining for the solution.
I want to get rid of this irritating overheating problem. Is there any option for replacement of NVIDIA GPU at my own cost even in some authorised service centre?

Thank you for confirming, that this can in some cases solve the overheating.
And i agree with you, that it is not straight forward, and people has to be carefull

Epson Photo R3000 prints as a negative, what is causing the interference?

Hi All
A frustrating morning, new printer arrives (yay!), but now I find my new Epson Photo R3000 prints fine from photoshop but prints come out as a negative image from aperture
I've already turned the printer settings to use colorsync rather than the epson engine for colour management to no avail - I have to assume that there's something in aperture that is being applied that is causing the issue, but just can't see what.
I can't be the first to find this as an issue with a new epson out of the box, Can anyone point me to where i can turn off whatever is causing the interference?
Best Regards
JT

interesting - this got me in the right direction.
Aperture was set to 'black and white', the printer dialogue was usign colorsync to enforce a paper profile generated by i1profiler an and i1io (or an epson profile).
when i set aperture's rendering brick to do it all 'in the printer' it's fine.
Cheers, knew it'd be something dumb!

TS3276 hi after updating to Mountain Lion, it becomes difficult to quit Mail, always have to Force Quit. And while Mail is on standby, the fan keeps on running full power, the laptop is hot. Why is this happening?

hi after updating to Mountain Lion, it becomes difficult to quit Mail, always have to Force Quit. And while Mail is on standby, the fan keeps on running full power, the laptop is hot. Why is this happening?

If your computer was hot it wasn't asleep - it either didn't go to sleep or it work up after you put it to sleep. I've seen both things happen. First, read this article and follow the instructions.
1) For the next few days/weeks pay attention to the blinking light on the front of your computer when you close the lid. Don't put the computer into your backpack/case until it begins to blink. Wait a minute or so after it starts to blink to make sure it doesn't stop blinking - the signal it woke back up.
2) having followed the above instructions, if you take the computer out and it is hot again or if you take it out and discover it has powered down (you'll know this because when it starts up the battery will be drained and you'll see a progress bar over a ghostly display that will eventually become normal) immediately start the Console program and perform a search on 'sleep' and then 'wake'. This should bring up all the recent log files about sleep state changes (going to sleep and waking up). You should see one for when you put the computer to sleep and put it away and the next one should be just after you got it out. You'll find at least one though that shouldn't be there. That will tell you when the computer work up (when it shouldn't have) and might give a clue as to why.
One of the whys could be a magnet that is making the computer think the lid has been opened.

Hello abyjohn,
I would be concerned too if the speaker on my iPhone was not working, and if I was getting a message about the accessory not being optimized. I found an article with some steps to take when you are experiencing issues like this.

Increase HDcapacity of hp pavilion dv5220us laptop

My laptop keeps restarting after I installed windows 7 and the Sound isint working either.
I want to Increase HDcapacity of hp pavilion dv5220us laptop from 120 GB to 500GB and the RAM to 2GB. Is it possible to do that and can I install windows 8. Recently a technician told me that it might not be possible to increase the HD capacity to 500 GB as it's an old laptop. I love this laptop and wanna fix it badly

It IS old. Built about 2006. It does use SATA hard drives (current form) so you can install a 500 gig hard drive and it can take up to 2 gigs of DDR (original version) 667 memory. A 500 gig hard drive and 2 x 1 gig modules of memory are going to cost you about $125. I would not spend that kind of money on a machine of that age. It will not run Windows 8 to full effect because the video chip is too old. Even Vista and 7 are a stretch. It was made to run XP and that would be the best OS for it. If it reboots and the sound does not work, you might even need a new motherboard.
Save your money for a new laptop or at least one that can handle the modern internet environment.

My ipad isnt charging when em connecting it with my laptop any one knows why ?

My ipad isnt charging when em connecting it with my laptop any one knows why ?

The iPad pulls 10 Watts of power in order to charge the battery. The USB port on a laptop only puts out 2.5 watts (I may be off on this slightly but I know it is way less then 10) So yes you do need to use the 10 watt wall charger that comes with the iPad to charge it. You can use the 5 watt charger from an iPhone but the iPad will not get to 100% charge and it will really overheat the iPhone wall charger. Only do this in an emergency and keep a close eye on the charger as it will get REALLY REALLY HOT. I only do this when I don't have my iPad wall charger with me and only for about 15 minutes at a time. Then I let the charger cool down for about 15 minutes before I plug it back in.
There is talk that future laptops will have usb ports that can push 100 watts but that is a way down the road I am sure.

Adjusting Contrast While Turning On Laptop Causes Flashing Globe

When I turn on my laptop in a dark room I sometimes make the mistake of trying to turn down contrast before the laptop has finished booting up. When I do this it always causes a flashing globe (image of the earth) to appear on the screen and it keeps flashing for a minute or two until it finally stops and boots as normal. Anyone have any idea what the heck is going on when that happens?
Thanks

It's always been a hardware issue, they just never successfully fixed it and declared it software related, hence why I had it in numerous times for the same issue
If the above fix doesn't solve your issue, then it sounds like a problem with the NVRAM that stores such information as what to boot from etc. and it's not showing up as a problem with their testers, but it is under daily use.
It's very highly likely they erased the drive and reinstalled the operating system at least once during the many times you took it in to eliminate a software issue.
My apple care just expired within the last few days and there's no way I can afford to pay out of pocket to have it fixed now (this last repair would of been $800 according to the receipt had I not had apple care).
It seems they have been misdiagnosing what in hardware is causing your issue and replacing the wrong thing or it's a casscade effect where something breaks and causes other parts to fail later.
I would take the machine back to Apple again and tell them it's still not properly fixed and if they resist, then pursue legal, public shaming and/or government action to get them to fix your machine properly or replace it with a used model.

I can't see the photos on my photo stream (laptop) on my iPhone. why?

I can't see all my photos on my iPhone 5s,i have to go to my laptop to see them (photo stream no longer on my iPhone). Why is this so, i thought you could view/delete photos from all devices.(running the latest software)

Photostream does not have an option to be backed up. If you backed up pictures from photostream then you will find them in the place of back up. If you just had your photostream "on" it was streaming to all devices connected back then, but will not sync over to new devices. It is rather streaming and not syncing service, so there is no option to go backward. There is a slight chance that you will still get last 30 days of your pictures, that is how long photostream server keeps those pictures for you.

W510 Solid State Drive (SSD) Gets Stuck Causing BSoD. Why?

Hey guys, this has been a problem for a while now, and it is really mind boggling ... I have a Lenovo ThinkPad W510 laptop with a 256GB Crucial M4 SSD drive. Ever so randomly the drive just hangs, the LED light that the drive is trying to load something stays "ON" for up to 5 minutes or so before it finally goes into a Blue Screen of Death (BSoD). Once it goes into BSoD the laptop reboots and it gets stuck on the ThinkPad motherboard logo, eventually it will display "ERROR 2100: HDD0 (Hard Disk Drive) initialization error (X)" Where X is usually 1 or 2, sometimes 3 but rarely. It will not function again until I physically turn it off and back on using the power button.
A little bit of background about the problem, this is my 3rd Crucial 256GB M4 SSD, Crucial has been very helpful and they went as far as replacing the drive twice, i am starting to highly doubt its a drive issue, I think it could be something from the laptop itself. To be more clear, my laptop has also been serviced back in March (Motherboard was swapped as well as keyboard), parts failure. It was all done in very timely manner and everything was OK after the swap.
A representative from Crucial told me that this is a classical problem with the SATA controller driver handling TRIM, he said the drive is getting stuck in an infinite TRIM state which causes the BSoD, after that the drive goes into some sort of a "panic" mode to protect itself and doesn't function again until a full power cycle. (thus the need to turn off and then on the laptop) he also added it could be fixed by installing the correct SATA controller driver.
I have tried to use the default windows SATA controller driver, and I have tried to use the Intel one too, and it seems to happen less often with the windows drivers, but overall, it happens at least once a day. It is really frustrating and I am not able to get anywhere with it.
Any help or advice is highly appreciated. I am considering getting rid of the Crucial SSD altogether and just using Intel SSD instead, but I am really doubtful that it is the SSD's fault especially that its the 3rd one I use. I also know a couple of friends who own ThinkPads with Crucial M4 SSD inside them, and they seem to be working very well for them.
Thanks in advance,
Al.

Hi again,
Ok so I have applied the fix you have mentioned above, and it did improve (lower) the frequency of the problem happening. It really improved a lot significantly when I uninstalled the Intel drivers and used the Windows 7 built in SATA controller drivers.
However, ... it still happens ... less frequent, but it still takes place, my SSD still gets stuck at least once in 3 days now, or once in 2 days (after severe testing) and the same scenario happens. I am really stuck at this point, and not sure which direction to take.
Any help would really be appreciated, if you have / know any method to debug the BSoD's I get and a way to locate the source of the problem I am willing to go through it 1 by 1 and solve this problem before deciding to finally just giving up on the drive altogether.
Sincerely,
Al.

I used my friend itune to transfer songs to my iphone 4 but when i am using itunes from my laptop i am not able to tranfer songs to iphone.. but from my friends laptop is working.. why and what need to do ?

I used my friend itune to transfer songs to my iphone 4 but when i am using itunes from my laptop i am not able to tranfer songs to iphone.. .. why and what need to do ?

I would suggest that join your iphone with iTunes and do not sync. Than in your info window of iTunes uncheck auto sync of songs and videos. Check Mark for manual selection of songs. Also uncheck sync of songs window. After this sync your iphone and manually copy your songs from your iphone through itune by opening music under your iphone icon in the left status bar and copy to your laptop music folder. I think it would help out. I did same for myself. Try out. TC
