• Pavilion dv4-1155se blink Code

  Hello

  I have a HP Pavilion dv4-1155se that turns off randomly. I noticed that the Caps/Scroll Lock button flashes 4 times when I try to turn it back on. After a few tries more I am able to re - turn on the computer and use it as usual.

  So, that means the code? I found this link, which indicates that it might be the "Graphics controller not functional. Is this true for the dv4-1155se?

  Thank you.

  Yes, those who blink codes are for your model.

  It is to have some kind of graphic problem.

  As a last resort, you can try a bios update if there is a newer than the currently installed version.

• 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,

  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.

• HP Pavilion dv4-1120br: doubts about the BIOS update for my model with the operating system current instaled.

  Hello

  I have a HP Pavilion dv4-1120br, I know that this model of HP laptop is old, but I instaled the 64 bit of Windows 10 on my machine and saw that my BIOS is version F.30 and the last of them available on the site of HP F.66 has.

  The problem is that this model is not suport for Windows 10 because, as I said, is too old. Can I download and run the update of the BIOS for Windows 7 64-bit available in the Web site, or I need to downgrade my OS to Windows 7, update the BIOS and then pass it back to Windows 10?

  Thanks for the help!

  Cantarino

  Hello;
  
  Let me welcome you on the HP forums!
  
  Your second proposal is correct - as the updates to the BIOS on the HP site are specific to the OS version and if you try to run one for Win7 in Win10, it will refuse to run.

  Good luck

• Cannot install driver for hp pavilion dv4-2045dx cd player

  Computer: HP Pavilion dv4 2045dx using Windows 7 (64-bit)

  I currently have problems with my computer's CD drive.  He has been unable to read discs of any kind of music, DVDS and software programs for several months now.  The main problem seems to be with an inability to properly install the driver for the cd drive.

  When running "find and solve the problems" of section "Troubleshooting" in the Control Panel, I get an error message that says that there is a problem with the driver for the cd drive.  Whenever I try to install the driver, he is not able to do so and contact the manufacturer of your computer.  I also tried to download all the updates and I get essentially the same message.

  Also, here's all that I've done so far.  I followed all these steps, but the last two listed in the help or support of the site.  Here is the link I used:

  http://support.HP.com/us-en/document/c01897812

  I couldn't do a restore of the system in step 7, because the last date that I could find to a restore point has been today (or yesterday).  In addition, I couldn't do step 8.

  Any help would be greatly appreciated.

  Thank you
