No sound/Crackling noise on my Compaq Presario CQ56-115DX Notebook

This computer is barely 3 months old. Everything worked fine first 2 weeks I had it but one day the sound went out. It didnt go out completely though. It goes in and out with this horrid crackling white noise. The better the sound gets the worse the white noise gets. I tried running every troubleshoot program i could find and everything says its working fine. My sound card is Realtek HD something or other. Yesterday I got an update for the bios from HP and it fixed the problem. But today it started happening again exactly the same. Im thinking something is wrong in the BIOs. The computer is still under warranty but i dont want to have to send it in and risk losing all of my stuff or getting my personel info hijacked. Please help!!!

i did the restore, too, and it didn't work. that's what baffled me! imagine restoring to factory default and the audio still does not work? i must admit that i did download one of the updates and got the audio working. it was temporary because as the Windows Vista updates were being applied, at one point I lost audio again.
i did a bit more research last night and found an interesting post. it requires manually amending some files, so i'm okay to give that a try. as this has been quite the issue to troubleshoot, i will post a solution if I find it. i don't want to settle on this... don't give up!

Compaq Presario CQ56-115DX Problems

Hello,
I have a Compaq Presario CQ56-115DX Laptop. It is still under warranty. Within the last week the power of the laptop has been messed up. When I have the laptop unplugged, which I don't very often, the laptop shuts down after an hour without any warning. So I plug back in the laptop and it still shows anywhere for 40-70 percent battery left. Why is it doing this?
Thanks

Hi,
First of all, shut down the notebook, unplug the AC Adapter, remove the battery, and then hold down the Power button for a full minute.
Now, plug in the AC Adapter without the battery inserted, start the notebook, open windows Control Panel, open Device Manager, expand the entry for Batteries, right click on and the Microsoft ACPI Compliant Control Method Battery and select Uninstall - do not uninstall anything else here. When the uninstall is complete, shut the notebook down, unplug the AC Adapter, re-insert the battery and then start the PC on just the battery. Windows will automatically reinstall the driver - leave Windows running for a few minutes. Shut down the PC again. Now plug in the AC Adapter ( with the battery still inserted ) and start the notebook to see if this has helped the issue at all.
If the above has not helped, download and run the stand-alone battery test utility available on the page below and see if this reports any problems with your battery.
http://h20239.www2.hp.com/techcenter/battery/battery_ts.htm
If this reports a problem with the battery ( or even if it doesn't, but the problem is still occuring ), contact HP and arrange to have the battery replaced/notebook repaired under warranty.
If you live in the US, contact HP Here.
If you are in another part of the world, start Here.

Compaq presario cq56 115dx will not power on blinking lights, not a disk drive problem

I own two identical Compaq Presario CQ56 115-DX, and the one I use every day stopped powering on. Shows blinking caps lock light and orange WIFI light does not turn blue to turn on. The fan powers on, but the screen doesn't come on at all. I tried hard resetting several times and it didn't work. I swapped the hard drive of the malfunctioning CQ56 to the other one that was working normally, and it works OK normally. No hard disk corruption or problems.
Any idea how to fix this problem laptop?

Hey @rajpodn ,
Welcome to the HP Forums!
I understand you're looking for info on swapping out the CPU in your notebook.
You will find everything you need here: Compaq Presario CQ56 Notebook PC - Maintenance and Service Guide. The instructions you need start on page 75. Keep in mind that the CPU itself may not be the issue, it could be the socket on the motherboard preventing the notebook from reading the CPU, so even replacing the CPU may not work, as you may need a replacement motherboard. I do not suggest replacing the motherboard as doing so requires HP Proprietary software to reinstall the Service-ID necessary for reinstalling Windows.
*Caution - If you do install the new CPU be careful with the thermal paste. A small pea sized amount should be more than enough. Put the paste in the exact center and carefully spread so there is a fine layer almost to the edge of the CPU. Remember that the heatsink will press very firmly onto the CPU and spread the paste more and you don't want any squishing out as this can cause electrical shorts if the paste has a high metal content.
The part you will want is: AMD V140 processor (2.3 GHz, 512-MB, L2 cache, 1066 MHz, 3.2 GT/s)—singlecore 25 W. The part number for this is: 616333-001.
You can order the CPU directly from HP here: HP Part Surfer, but you may be able to find it cheaper on sites like eBay, Amazon, or Newegg.
Hopefully this covers everything you're after!

Compaq Presario CQ56-115DX will not turn on

I have a Compaq Presario CQ-56 115DX that is almost a year old. My system first had problems crashing whenever I would watch video content, I reinstalled both Java and Flash, but that did not resolve anything. After that my computer would keep checking my file system on C for consistency whenever I would turn it on, even after telling me that it found no problems. After that I received a message that my C file system was corrupted, I attempted to back up my files and do a system restore to the factory settings but it crashed during the process. Since then it will not turn on all the way though the battery will charge and the On button lights up, as do the WiFi key and the Caps Lock key. (The Caps lock key blinks once, which according to the HP errors signal website means that the CPU has problems.) I have tried holding down the button to reset it, I have also taken out the battery and plugged it in.
Is there anything I can do to repair this? Or is it a lost cause?

Does Compaq Presario R3000 (AMD) Notebook PC support WPA2-PSK?

Hello all,
I know this is an old laptop(Compaq Presario R3000 (AMD) Notebook PC).
Recently, I upgraded my network system and start to use WPA2-PSK.
I have installed the patch from MS http://www.microsoft.com/en-us/download/details.aspx?id=1974
However, the droplist of my network wireless setting still doesn't show the option
for wpa2 but wpa.
Can someone tell me the reason? Is it beause that my network adapter doesn't support
the new standard wpa2?
Thank you
This question was solved.

I believe this driver will take care of the issue...
http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=3688870&sp...
Again, in addition to the above driver you also must be running XP SP3 in order to get WPA2 support if that microsoft SP2 WPA2 patch doesn't work.

Compaq Presario CQ56 beep while working and working temperature

Hi,
I Have a Compaq Presario CQ56 with Windows 7 Ultimate (32Bit), ADM V140 CPU, 2GB of DDR3 RAM and an AMD Mobility Radeon HD 4250, and a SAMSUNG 250GB HDD.
While i am playing some random games like Need for Speed Carbon, Need for Speed World on Low-Medium graphics, i hear a long beep and then a click from the laptop, somewhere from the DVD-RW Drive. It only occured twice do far. The laptop works normal tho after the beeps.
Also, the temerature is worrying me, it goes up to 75C while playing, but goes down to 60-65 while internet and around 54 while idle (lid closed).
Sorry for my grammar i am Serbian.
Thanks in advance!

Those temperatures are a bit high, but still well within normal range. We see a lot of people reporting temperatures in the 90C ranges. The beep is a mystery to me.
