How do i fix my LCD?


Hi,
I have got a hp pavilion dv5000, when I turn on it the screen goes blank.

Power led glows, I hear for a few time the fan, disk led flashes intermittently and also I feel that the DVD player tries to load.

If I try to click on caps lock or num lock, leds don't respond to commands. I tried the hard reset pressing the power button for 30 seconds with the battery and the power removed. Nothing to be done by connecting an external monitor....

What can I do ?qqb002.gif

Thank you

My laptop screen is black and caps lock and scroll key are flashing


That is a security configuration on HP Laptops, depending on the way they blink is the problem your machine has.

Here is the web page where this info is posted, in case you need more info, hope this helps you to determain.

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01443366&lc=en&dlc=en&cc=uk&lang=en&rule=26781&product=3816592
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. Caps Lock/Num Lock LED Component Tested Error Condition LEDs blink 1 time CPU CPU not functional LEDs blink 2 times BIOS BIOS corruption failure LEDs blink 3 times Memory Module error not functional LEDs blink 4 times Graphics Graphics controller not functional LEDs blink 5 times System board General system board failure LEDs blink 6 times BIOS BIOS authentication failure

It would seem that your BIOS has become corrupted somehow. First try entering your BIOS setup. I believe for HP computers when you press power tap the F10 key until it opens. There you can try to reset them in some fashion and save. Try rebooting. If that fails then remove the battery and repeatedly press the power button for about 10 seconds.. (make sure it is also unplugged, this is to discharge the power from the system) then replace the battery and try booting again. Otherwise it would seem that you might have tried to load the wrong BIOS into your laptop. Check with HP then if you are still covered or not. :/

Run the Dell Diagnostics Utility by pressing Fn+Power button at the same time.

If the Diagnostics doesn't come up, your motherboard needs replacement.

Blank screen on laptop


Sorry to hear you are having problems. I have had this same issue before with this particular model. The following solution works 90% of the time.Perform a hard reset as the first procedure.
  1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
  3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
Meaning of Sample Blink Codes for some EFI Notebooks Number of Blinks or Beeps Location of Blinking LEDs Component Being Checked Error Condition Continuous glow Battery power LED Battery The AC adapter is attached and the battery is charging, but does not yet have sufficient charge to power the notebook. 1 Caps Lock/Num Lock CPU CPU not functional 2 Caps Lock/Num Lock BIOS BIOS corruption failure 3 Caps Lock/Num Lock Memory Module error not functional 4 Caps Lock/Num Lock Graphics Graphics controller not functional 5 Caps Lock/Num Lock System board General system board failure 6 Caps Lock/Num Lock BIOS BIOS authentication failure Continuous blink AC power adapter LED Power adapter Insufficient power
Blink codes are often displayed after a user adds memory to the computer but does not seat the module properly. The LEDs may also blink error codes if a hardware component is loose because the computer was dropped or jarred. Some HP Notebook PCs come with one stick of memory but have two memory slots. The problem could be that the stick of memory or one of the memory slots has a bad connection. The memory module compartment on most notebooks is located on the bottom of the case. The exact position varies by model. However, on some models, the memory compartment is under the keyboard. See your User Guide for the exact location of memory modules on your notebook.

Use the following steps to remove and reseat the memory modules: Step 1 - Remove the electrical power To remove all power from the computer and prevent accidental damage to the electronic components, do the following:
  1. Turn off the computer by pressing and holding down the Power button for about 30 seconds.
  2. Unplug the AC adaptor from the notebook.
  3. Slide and hold the battery release latch to the unlock position.
  4. Use your finger to lift the battery up and out.

  • Remove the memory module cover on the bottom of the notebook .Loosen the compartment's retention screws and lift up and remove the memory compartment cover. Remove the memory modules from the memory slots To prevent damage to the memory module, grasp the memory module by the side edges. Do not touch the metal contacts.
    1 - Pull the retention clips away from sides of the memory module
    2 - Gently pull the module out of the memory module slot
  • Reseat the memory module by holding module at a 45-degree angle, and pressing it firmly into the memory slot until it is seated.

    After reseating the memory module, replace the cover over the memory compartment before restarting the computer

    Hope this helps FiYa! If you find this solution helpful, please take a moment to leave us some feedback.

    Thank You!

    If the Num lock is lit constant, and the Caps Lock and Scroll Lock keys are flashing, the system is reporting a memory error. Power off the system, remove the battery, and follow the user manual from support.dell.com to reseat the memory module(s). If the error persists, you may need to replace the memory and/or the system board of the portable.
