I had the same exact problem. I took it upon my self and replaced the screen and all sorts of things, but the problem had to do with the thermal sealing on the processor. I paid about 75 to have the repairs, but I wasted way more self diagnosising.

There were few cases why this would happen:

1- wall outlet problem insufficient current to drive the power causing less voltage ( change the wall connectivity )
2- erratic contact in RAM, (reset the Memory module, clean the contacts with pencil eraser )
3- Damaged power supply (change adapter or try another one with similar plug and specs.
4- Mother board problem
5- loose connection, from the PC adaptor to Laptop
6- loose connection from wall outlet

pls check these

Follow the steps below to determine whether the problem is related to the AC adapter or your notebook system board:

  1. Remove the battery and disconnect all external devices from the computer.
  2. Hold the Power button for several seconds, with all power sources removed. This drains residual power from the system, and may correct many problems.
  3. Connect the AC adapter to a wall outlet and plug the other end into the computer.
  4. Press the Power button .
  5. Is the Power indicator light (LED) on or off?
****If notebook power indicator light (LED) is on, the AC adapter is working correctly***
If the power indicator LED is off, the AC power adapter may need to be replaced. To determine if the AC power adapter needs to be replaced follow the steps below:
  1. Ensure that the AC adapter is plugged directly into a known working wall outlet.
    NOTE: To check the wall outlet, plug in a different known working device like a light, radio etc.
  2. Check all of the following connections:
    • The connection from the AC adapter to the wall outlet.
    • The connection into the power adapter from the wall outlet.
    • The connection from the AC adapter to the notebook.
  3. Press the power button again to test the notebook PC.
  4. If the power indicator does not turn on, remove the AC power adapter from the notebook PC and re-insert the battery. Then press the power button. If the power indicator light still does not turn on, then the AC Adapter needs to be replaced.
*****Reseating the RAM may resolve this issue.****
Step 1 - Remove the battery
  1. Slide and hold the battery release latch to the unlock position.
  2. Use your finger to lift the battery up and out.
Step 2 - Remove the memory module
  1. Locate the memory module cover on the bottom of the notebook.
  2. Remove the screw that covers the memory module.
  3. Use your finger or a flat head screw driver to lift the inside edge of the memory module and remove it.
  4. Push both tabs outward simultaneously to release the memory module.
  5. Grasp the memory module by the edges and pull gently to remove it.
  6. After removing one module, replace the memory expansion cover and then replace the screw.
Step 3 - Replace the battery
  1. Insert the battery into the notebook.
  2. Push the battery into the base enclosure until you hear a click.
  3. Connect the AC adapter and turn on the notebook.
fter the memory is reseated, connect the AC adapter and turn on the notebook. If the notebook boots normally and the Windows desktop appears no further action is needed. If this problem re-occurs often, contact an HP Support Specialist to schedule a repair.

Pavilion dv4 display horizontal flashing lines across the lower screen in taskbar area


I'm Sorry to say but it could be that you need a new screen (easy repair around $195) unless you go to HP
Or it could be the built in video card (much harder to repair)
Do the lines appear from start up or slowly get worse as the comp gets hotter, if this is the case it is more likely the video card then I would contact HP to get a quote, But first,
Try plugging your laptop into an external monitor & see if the lines show up then

Hi Friend, In this case I would recommend you to please try and connect any external monitor to the system to check if you have the same issue with the external as well.
If you see the same issue happening on the external one as well, i would recommend you to try updating the video drivers for the system
If the external one is fine, then I believe the LCD needs to be checked or repaired
Please let me know if it was of any help.
Thank you.

HP (dv2000) laptop will not boot up at all


It appears to be a video card/mainboard problem very common with the symptoms you have described. Try to connect the laptop to an external monitor (see the associated buttons too). No video signal on the external monitor could indicate a damaged video card/mainboard. Not worth it to be repaired and the replacement is expansive. Check the price on a professional repair store. There are new laptops on the market more powerful than yours for about 500-600$. So you can make a choice. Less common, could be a memory problem.Try the laptop with a good previously checked memory (or if there are 2 bars in your laptop, try them one by one). If you do not get any video signal on the external monitor have the laptop, first diagnostic is most probable.
In both cases, if you get a video signal on the external monitor it means your screen is defective (also expensive to be replaced).

Hi, I have an HP pavillion dv6000 and the problem is that it doesn't start, i have just bought a new ram, but it still doesnt start, can you please help thanks


These Laptops have an inherent problem with the Video chip. If the computer is powering on but you are not seeing a video on the screen, try using an external monitor on the laptop vga port. If you can get a picture on the external monitor, you have an issue with your screen, and it needs changing. If you cannot get a picture on the external monitor, your video chip is bad and the laptop is finished. Reflowing the graphic chip is usually useless.

Good Luck

 Hello jarkk, I believe your problem is with your backlight inverter. the hard drive should be installed for this process of checking it on an external monitor. with the hard drive removed it will not boot to the operating system. with the drive in, use the external monitor. if the monitor works when plugged into the external monitor plug, this will eliminate a bad video card. if the screen is still black on the laptop screen, replace your backlight inverter. the last case cenario is to make sure your backlights are not burnt out.
