Question about Computers & Internet

Open Question

Hp nw8430 When I first turn the computer on it gets stuck on the bootup process, with a blank screen. the dvd rom lights continues to blink and I can also hear the dvd rom drive reseting. if I was to loosen the screws that hold the keyboard, the computer will start in a few attempts. and the it works fine after that. I'm pretty sure it gets stuck during the bios check some kind of hardware issue, i've heard that these particular laptops have some kind of problems with the design. it would be nice if you could share some light on this matter, replacing the motherboard is expensive. may be there is a components that need to be re-balled. Thanks for you answer.

yes sounds like the board has gone out on you.

You will have to watch ebay for a board. I just searched and nothing except batterys and keyboards are available.

First, Pull the hard drive. If the hard drive shorts out it can cause all sorts of problems. Generally it detects Hdd before mouse and keyboard.

Hi

If your HP laptop is a Pavilion dv2000, dv6000, or dv9000 series or Compaq Presario v3000 or v6000 series go to the link below on HP s website. They have extended the warranty to 24 months on many of these because of no boot, no display and other problems.

This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008. On startup, you may see a blank screen. If the diagnostic utilities detect a specific problem with hardware components, the fan turns on, but the screen remains blank. To help identify the cause of the problem, various LED lights on the keyboard blink a series of codes. The diagnostic utilities use the LEDs near the Num Lock or Caps Lock keys to blink a series of error codes. At the end of the series the blinking stops. The pattern of blinks will occur any time you attempt to start the computer until the error is resolved. Battery power LED blinks The Battery power LED indicates the condition of the power supply. When starting the computer, or when the computer is in operation, use the chart to identify the power condition. Battery Power LED Component Tested Error Condition Battery power LED off, and Caps Lock/Num Lock off Battery or AC Adapter AC adapter not connected or failure

Battery low charge or failure Battery power LED blinking Battery Insufficient charge on the battery When new computer is used for first time, the white LED light for the AC power connector blinks. Battery is still in "Shipping Mode", the light continues to blink even when AC power is connected.

To resolve, turn off notebook, connect AC power and allow battery to charge for at least 30 minutes, then start computer. LEDs near Caps Lock and Number Lock keys blink when starting notebook The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition. Knowing the number of blinks is helpful when you contact an HP support agent for technical help.

How do I format a DVD+RW disc?


Hello and Welcome to FixYa!

Here are the instructions for formatting DVD+RW discs.

  • Locate the CD-ROM drive door on your computer. The location of the drive depends on the computer you have. You will see a small rectangular button on the door.

  • Press the button and the drive door should slightly open. Lightly pull the door open and insert the blank DVD-RW disc into the drive. Close the drive door and wait for the computer to detect the disc, which will trigger an "Auto Play" screen to flash on the desktop's taskbar. The screen will prompt you to choose an action you'd like to perform for the disc.

  • Click "Burn Files to Disc: Using Windows." This link will redirect you to your Windows Explorer disc burning application. You will be prompted to enter a title for the disc.

  • Enter the title of your choice in the form and click "Next." The last screen will ask if you'd like to continue with the formatting; click "Yes" to continue. The "Elapsed Time" screen will appear indicating how long the process will take. When the process is complete, another screen will automatically appear indicating the formatting process is complete.

  • Click "OK" to continue. Your Windows Explorer panel will appear. In the upper-left corner of the panel, you will see a horizontal menu bar with different options for the disc. Now your disc is formatted and you can begin burning files to your disc.



    Have a nice Day,



    Concerned.

    Powers on wont post but dvd rom


    Eject any disk from the DVD device.
    Turn the computer off.
    Disconnect the "data" and/or the "power" connectors from the DVD-ROM.
    Turn the computer on, and see if it starts when the DVD-ROM is not part of your system.
    If it starts, then your DVD-ROM needs to be replaced.

    In 19 years of working on computers I've seen 1 bad Intel CPU and it still worked it just showed the wrong processor speed. I'd eliminate the CPU being the problem. Generally if you have a bare system with motherboard, ram, keyboard and video and they turn on the system is good. The video may cause a crash if it's bad somewhere in the bootup process going into windows but it shouldn't stop the initial bootup process. The area I would likely suspect is the hard drive. If the arm inside the drive that controls the heads is loose it can cause the drive to read sometimes when cool and then to start slipping and not read when the system is warmer. If you can get into the bios there should be someplace there to check your temperatures and voltages. Those might be a suspect area. If the power supply isn't delivering the proper voltages or the CPU is getting hot could cause problems also. I'd like to hear more about what you're seeing on the screen when this system fails to boot. Does is show the ram countup, system devices and hard drives as detected in the bootup process? Or is the screen just blank. When it doesn't boot does the hard drive light blink continuously?
