Video failure is a very common issue with HP Pavilion dv2000, dv6000 and dv9000 series notebooks. It happens because of poor design of the cooling module. The video chip overheats and separates from the motherboard.

Don’t want to fix it yourself? Check out these motherboard repair offers.

VIDEO FAILURE SYMPTOMS:

1. Notebook turns on, all LED lights light up properly but nothing appears on the internal LCD screen. The notebook LCD screen is completely blank and black. Also, there is no video on the external monitor attached to the notebook.

2. Video on the notebook screen and external monitor is garbled.

HP KNOWS ABOUT THIS PROBLEM:

HP knows about this problem with dv2000, dv6000 and dv9000 notebooks. Some qualified models HP fixes at no charge by replacing the motherboard.

Read more about HP Limited Warranty Service Enhancement program. There is a chance you get a free repair from HP.

If not, you’ll have to fix the notebook at your own expense.

Basically you have two options:

1. Replace the whole motherboard with a new one.

2. Fix the failed video chip as it shown on the video.

As an example the author is fixing an HP Pavilion dv9000 notebook but same technique can be used on HP Pavilion dv2000 and dv6000.

In this guide I explain how to access and replace the web camera in HP Compaq 6730s and 6735s notebooks.

The web camera is mounted inside the display panel above the LCD screen. In order to access and replace the web camera it’s necessary to disassemble the display panel.

Let’s start. First of all turn off the notebook and remove the battery.

STEP 1.

There are four screws securing the LCD bezel on the top of the display panel. These screws are hidden under four covers.

Remove all four covers with a sharp object and remove four screws found under those covers.

Screw covers have a sticky bottom. Glue them somewhere on the bezel so they don’t get lost.

STEP 2.

Start separating the LCD bezel from the display cover with your fingers. A guitar pick is very helpful and works great as a case cracker.

STEP 3.

Separate the LCD bezel from the display cover and access the web camera module.

The web camera is attached to the display cover with double sided tape.

STEP 4.

Carefully remove the web camera module and disconnect the cable on the right side.

STEP 5.

Now you can replace the web camera module with a new one.

In my laptop (HP Compaq 6735s) I used a new web camera with the following HP part number: 494110-001

Before the repair the web camera couldn’t start. Reinstalling the operating system and webcam driver didn’t help.

As soon as I replaced the web camera module, it started properly.

REMOVING LCD SCREEN

By the way, if you would like to disassemble the display panel and remove the LCD screen, you’ll have to remove four more screws on the bottom (hidden under four covers).

Unfortunately, you can remove the LCD bezel completely only when the display panel is separated from the notebook base.

In order to separate the display panel, follow steps 1-9 in this HP Compaq 6730s and 6735s guide.

In this post I explain how to disassemble the display panel on an HP Pavilion dv7 series notebooks.

I’m taking apart an HP Pavilion dv7t-1000 notebook PC but my instructions should work for all models in the Pavilion dv7 line. If this guide works for you please mention the notebook model number in comments after the post.

By the way, in the previous guide I explain how to completely disassemble an HP Pavilion dv7 series notebook.

Before you start, turn off the laptop and remove the battery.

Using a sharp object remove the left screw cover. After that remove the screw.

STEP 2.

Using same technique remove the right screw cover. After that remove the screw.

STEP 3.

Start separating the LCD screen bezel from the display cover on the top. You can use a guitar pick as a case cracker.

Insert the guitar pick between the bezel and cover and slowly move along display side. Continue removing the screen bezel with your fingers.

STEP 4.

Continue removing the LCD screen bezel.

STEP 5.

In this guide I explain how to remove and upgrade memory modules in HP Compaq nc8430, nw8440 and nx8420 notebooks. In my example I’m upgrading a Compaq nc8430 notebook. Most likely you can use this guide for some other Compaq notebooks. If it works for you, please mention the notebook model in comments after the post.

My notebook came with 1 GB (two 512MB modules). After reading the service manual, I found that this model can take up to 4GB total. You can install up to 2GB memory module into each slot. 4GB memory upgrade kits (2×2GB) are available here. HP recommends using PC-4200 DDR2-533 SODIMM memory modules.

If you cannot find PC-4200 DDR2-533 memory, you can use PC-5300 DDR2-677 or PC-6400 DDR2-800 modules. They should work fine.

These notebooks have 2 memory slots available. One slot (external) can be accessed through the door on the bottom. Another slot (internal) is hidden under the keyboard.

Before you start, turn off the laptop and remove the battery.

Remove the memory door from the bottom of the notebook. Upgrade existing 512MB memory module with a new 2GB module.

In order to remove the keyboard, you’ll have to remove two screws on the bottom. These screws are shown on the following picture. Use a T8 torx screwdriver.

There are four retention tabs securing the keyboard to the notebook case.

Slide all four retention tabs towards the touch pad.

Carefully lift up the keyboard and place it upside down on the palm rest.

The keyboard is connected to the motherboard. It’s not necessary to disconnect the keyboard in order to upgrade memory in the internal slot.

Now you can access the internal memory slot.

Remove existing 512MB module and replace it with a new 2GB module.

That’s it! Assemble the notebook back together and turn it on. New memory will be detected and configured automatically on the first reboot.

In this guide I explain how to remove the keyboard and clean the cooling fan in an HP Compaq 6515b laptop. Most likely this guide will work for some other HP Compaq model. If it works for you, please mention the laptop model number in the comments below.

You disconnect the keyboard only if you want to replace it with a new keyboard.

STEP 5.

The cooling fan is located in the top left corner.

If the cooling fan and heat sink are dusty, you can clean them using canned air or air compressor. Blow air inside the fan until all dust is gone.

Also, under the keyboard you can access the hidden memory slot and CMOS battery.
