• Pavilion dv4-1540us: No Sound from speakers - Pavilion dv4-1540us

  On this laptop's built-in speakers do not seem to work. I suspect that it's a hardware problem and not a Windows/driver setting as the sound is fine with headphones or external speakers, but of course I could be wrong on this matter. All the obvious settings seem to be correct. An indication of error only I see is the light the speaker on the base (above the keyboard) is amber continuously.

  I checked all the Windows updates and there is no error in the Device Manager. Any ideas/suggestions on what I need to check? If additional information is needed, please let me know and I'll be happy to provide it. Thank you in advance.

  Use the button at the top of this page titled "support"-click on "Download drivers" in the menu. "." Enter your model number. After you click "Go". On the next page use Option 2 to access the list of drivers. Make sure that Windows 7 is chosen if no Edit to change. A list will populate with the drivers/software.

• Windows Resume Loader black screen on HP Pavilion dv4-2145 dx laptop Windows 7

  I have a HP Pavilion dv4-2145 dx laptop with Windows 7. After pressing the button "on", the logo operation windows says its "recovery" windows, but a black screen titled "Windows Resume Loader" appears with the following message:

  The last attempt to resume the system from its previous location failed. Attempt to resume again?

  With the 2 following options:

  1. continue with system summary, (which does not work and I end up with the resumption of the "Windows" followed a blank black screen...)

  2 Delete restoration data and proceed to system boot menu (I haven't ' truei stops because I wasn't sure what that meant)

  But I managed to go to the reviews section diagnostic systems and it seems that he pass all 5 of the test, including hard drive and memory, poster, etc. So I don't know what the problem...

  Please notify.

  Thank you very much!

  Hello

  I think that in this case, you will have to choose the second option - "Delete restoration data and proceed to system boot menu" and see if that fixes the problem.  If all etc. documents you had open before hibernation were saved, then you should not lose anything.  If there are unsaved changes (for example if you have added to a document), the file will be to the point that his last record and you lose additional data.

• HP Pavilion dv4 screen black 1428dx / refuses to start up

  I have problems with my laptop (HP Pavilion dv4 1428dx) the last thing I did was paused, then cameback and tried to wake him up but it would not start up. All the lights are on, but the screen is black and the only thing that I hear the fan moving. The caps lock and num lock keys have a light flashing, not really sure what it means. The power light, battery light comes on, but the hard drive LED is not on. This computer is nearly 3 years old and I've never had a major problem like this until recently. If anyone has a solution that I'd be happy to appreciate them.

  Thank you for your time,

  Freshman4002

  The blink codes State caps lock/caps lock Num because it might be just the caps, just the number lock lock, or both.  If both blink, then it counts as a blink every time.

  If it flashes once and a break of 3 or 4 seconds, then tells the CPU POST test failed.  A processor failure usually requires a new processor, but some have been able to open Notepad for reinstall process and apply new thermal paste to get the problem resolved.

  If it is under warranty, I would advise you contact HP for service.

  If it is out of warranty, then I would contact HP to get a quote and compare that to the cost of a local PC shop to weigh your options.

• Screen & player stalls voids on Pavilion dv4-2045dx

  Having formerly operating Pavilion dv4-2045dx a friend.  When turned on, no screen activity is displayed.  Hard diving turns upward, but not for very long, so it doesn't seem as if Windows is actually behind the empty screen loading.  I tried to connect a monitor to the display port, but nothing appears on the external monitor or integrated display.  The command has been removed and the data seems to be intact.

  I guess the screen is dead and with it the computer.  Any suggestions before I tell him, is it time for a new laptop?

  Physically, you need to open the case and look at the type of processor before ordering a new. I'm not sure of the dv4 on top of my head, but some use laptops that are welded on the processors and you should replace the whole Board. In addition, with processors, you might be able to get more life out of it by scraping of old thermal compound on the CPU and the heat sink and thermal paste new application.

• Pavilion dv4-2155dx screen shows no info on the first boot

  My machine generally works very well, except for one annoying thing: on my previous Pavilion (dv4-1435dx), he showed the HP logo and a message that made me know I could press F2 or do anything to get into the BIOS setup screen.

  But on this machine, all I get is a black screen, which makes it very difficult to know when to start press any function button is necessary.

  Is there a way to turn it back on, or it has never been available on this model?

  If someone knows something, your help is appreciated!

  _______________________________________

  The PDADoc!

  I think that HP this disabled by default on new versions of the bios, use F10 to enter the bios and see if there is a setting, you can change to return to the home screen, or press ESC to show for this start-up cycle.

  Key to the new laptops HP options, everyone can work on your

  ESC = Boot screen

  F1 = Information System

  F2 = System Diagnostics

  F9 = Startup Manager

  F10 = Bios setup

  F11 = HP System Recovery

  F12 = Network Boot

  After using F10 to enter the bios use F9 to load the bios default settings.

• computer HP pavilion dv4 laptop has this thin line at the bottom of the screen, need help?

  Hello, recently my HP Pavilion dv4 has been glitching, theres this thin line at the bottom which is a whitesh and flashes very quickly. At first I thought it was because of overheating because of the summer, but I'm not so sure most since the weather has been kind lately.

  Thank you!

  I'm sorry but that's the problem with the display panel. You will be able to solve this problem by replacing the display panel only.

• His stutters on Pavilion dv4-1120us

  I had my Pavilion dv4 1120us for Christmas and put it in place. It is under Vista Home premium with SP1. I noticed that from time to time during sound playback slows and stutters for a few seconds and then the catch usually upward. He made cela hung together through its speakers and external speakers. The condition seems insensitive to changes in devices. I noticed that no special request is responsible for either. It occurred when streamming myspace and playlist.com, when watching a dvd in both media center, wmp and VLC, windows included during playback of CD and by practicing a game (total annihilation). I also noticed that the problem persisted even when I extracted decrease the number of processes ranging from 80 to 60 something.
  I thought that the problem may lie simply in Vista and the bloat-ware that came on the computer. Today I inistalled dual-boot ubuntu and the problem is ongoing, as well as the headphone jack and speakers single switch with Vista (I think it's just a driver issue...), I would like to know how to solve the problem at least with Vista and with linux so would be good. Thanks for any help.

  just a Word to all those who want to run ubuntu on the hp all, for those with audio HDA sound bugs are at http://ubuntuforums.org/showthread.php?t=1043568.   Thanks for all the help.

• leader revovery pavilion dv4 1225dx

  My pavilion dv4 1225dx stopped randomly start, showed a blank screen and the caps and scroll lights were blink every few seconds. What I've read, it is unfortunately a major problem. I tried a hard reset, taking and in the stack, the stack of the RTC, try different combinations of these two modules and WLAN module to see if the computer should start without it. Nothing has worked.

  I understand that my computer is done at this stage, but I need to get the files out of it. Can I use a USB adapter cable to transfer the files from my hard drive? If so, how?

  -Desperate and tired-

  Hello

  Probably your best option is to remove the hard - see Page 68 of your Service Guide & -place it in an external enclosure (an example of what you need is on the link below), that connect to another PC and see if you can access your files.

  External 2.5 HARD drive caddy ".
