• 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.

• Second request - rolling screen Pavilion dv4-1540us

  I'm sorry I clicked on the Solution. I have not found the solution. I tried to connect the laptop to a TV via HDMI and it said no Signal.  What problem we can trouble first pull or rolling screen HDMI connectivity.

  I posted yesterday morning on this subject, and now, I searched all morning for a HP solution on what seems to be a common problem. Some people have made suggestions, but I cannont find where an Expert HP gave the solution. Many say they have to ship computers that are still under warranty. Please let know us if this is the case.

• Pavilion dv4: Windows 7 does not start and I can't access the system with f11 recovery

  I use a Pavilion dv4. Windows just crashed on a blue screen with a message about physical memory dump. Now when I start the computer it will just a black screen with a blinking cursor to the place when windows normally should start. I can not access the system with the f11 key recovery. I went in with the f2 key diagnostic mode. Diagnostic tests except for the battery test that failed, but shouldn't the laptop to be able to run without a battery if it is connected? And besides, if the problem was the battery, the laptop wouldn't be able to turn on at all, no?

  I'm not about to spend all that money on a battery just to know that it is not the battery.

  Hello

  If you have the 64 bit rescue CD, you would have received an error if it was bad.

  Once you have all your data backup, try the following - which means that Windows has been installed on the C Partition.

  Boot from the new rescue CD, select repair your computer and choose the command line.  When this charge, enter the following commands and press on enter after everyone – including spaces as shown.

  Bootrec.exe

  bcdedit/export C:\BCD_Backup

  c:

  Boot CD

  BCD attrib s h - r

  Ren c:\boot\bcd BCD.old

  Bootrec /RebuildBcd

  Bootrec /fixmbr

  Bootrec /fixboot

  Remove the rescue CD and try to restart now.

  Kind regards
