Question about HP Pavilion dv2415nr Laptop

1 Answer

HP Pavillion DV2000 (dv2415)laptop w AMD Turion64X2, running Windows Vista. The problem appears to be a power up issue where, when the laptop is initially turned on, all the various lighted buttons around the keyboard area light up an simply stay lit. there is also heard thea couple of "seeks" preformed by the CD/DVD drive with its activity light flashing. there is NEVER any activity on the LCD screen (on display of POST/boot-up/OS startup etc; it simply remains blank. If the laptop is left in this state for a few minutes eventually the fan will be heard as well as you can feel a modest amount of heat blowing out the laptop's venting. However, at one point, recently, the laptop, for a short peroid of time appeared to go through a normal power-up and OS startup, and would function correctly for entire sessions without noticable difficulty until the laptop was normally shut down. Several restarts (over a several days) of the laptop were successful, ie. keyboards lights flahed momentarily, then the screen would light and display all the normal system start screens and messages and anormal log-on into the OS was possible. Then suddenly the power/startup "hangs" failure reappeared once again, and remains in this state as of this writing. For the brief period, while this laptop suddenly became functional, normal diagnostics did not reveal and immemint or potiential problems or issues, in either software or heardware, all components were operational. Some advice offered so far have suggested every thing from a motherboard failures, Ndivia display chip issues, bridge chips problems and bad AMD chip set difficulties. What is actually replaceable/servicable at reasonable cost or effort, I really would like to save this machine if at all possible. Any insights and or help as to the nature of what I am facing in attempting to get this laptop fuctional again would be most helpful and appreciated. Dennis djmajkowski@att.net

    We can troubleshoot the Overheat issue but first we need to turn it on. Perform following steps and check if you can see the diplay on screen.

    1. Disconnect the AC Adapter.
    2. Remove the Battery.
    3. Hold the Power button down for 30 seconds to 1 minute.
    4. Reconnect the AC adapter and do NOT connect the battery now.
    5. Turn on the Notebook power.

    If the Notebook power up and shows you display, then proceed with further steps (or you can connect a desktop monitor to check if its displaying. Press Fn F4 to toggle the display on external monitor)

    The notebook may overheat and make noise or stop working due to the following conditions:
    1. Due to incorrect power supply from the AC adapter.
    2. If the Fans/Heat Sink are not working properly.
    3. If the power management and BIOS settings are messed up in the Notebook.
    4. Finally due to other components on the system board.

    To resolve this problem with overheating, perform following steps.

    I check your Laptop and see that your Laptop product number is "GA534UA#ABA" with Windows® Vista Home Premium pre-installed, if you are using the same, process with following steps.

    Step 1: Reset the BIOS to factory defaults:
    1. Click Start, Turn Off Computer, Restart.
    2. When the HP logo appears, press F10 to enter BIOS Setup.
    3. Press F9 when you are in BIOS Utility to load the BIOS to default. Click YES. Then press F10 to Save

In case there is no display, remove and reseat the Hard Disk and RAM and check for the issue. If display comes up after removing and reseating the RAM and HDD, then you need to follow the above steps again.

NOTE: If you have more than one memory module, you should test them individually to determine if one or both of them are faulty. Insert each module separately, then turn on the notebook to determine if the inserted module is working. Once you have determined which memory module is faulty, you can replace the faulty module and reseat the working module.

Hp pavillion dv2000 from windows vista converted into windows 7 ultimate and audio driver does not work. No sound when downloaded a driver for windows 7. please help...


Unfortunately the HP Pavilion DV2000 came with Windows Vista and HP does not have the complete set of drivers, specially for Windows 7. In these situation, it is best to go directly to the hardware manufacturer's website to get the necessary drivers. Keep in mind that computer manufacturers are not really manufacturers. They just merely assemble these computers. They order the parts from different manufacturers. Here is a link where you can download the Window 7 compatible driver for the audio card that you have in your portable system. Just click on the download button in the middle of the page.

I m using ur model HP PAVILLION DV2000


Sounds like you have a driver issue.

Start up in safe mode (press the F8 button about once per second after you power on), and select safe mode with networking.

When you get into windows, use windows update to download all updates for both software and hardware (update will till you that there are optional updates available, download these as well),

Hopefully when all that has completed you should be able to run your computer as normal. If not there may be a problem with the memory installed on the laptop.
