The HP 250 G4 is a budget business notebook computer that offers some great hardware configuration for its price. However, there are a few downsides with the notebook, and one of those downsides is the integrated display. Depending on the computer’s configuration, you may have a display panel where the color looks washed out along with a blue tint. If you’re technical enough, you could replace the display panel with a better one, or you can do some color adjustments that can drastically improve the color.

Note: These color adjustments are my personal settings and were preformed on a HP 250 G4 notebook with Intel graphics. AMD/ATI graphics may yield in slightly different results depending on its software. Similar HP models also apply as well as any notebook using the same display panel and modern Intel graphics.

First, make sure you have the latest Intel graphic drivers installed.

If the notebook is running on batteries, plug in the AC adapter and turn the display’s brightness up to 100%. (You can set it back after you’re done).

Go to the Control Panel and open the Intel HD Graphics applet. When it opens, click on Display.

On the left hand side, select Color Settings. Make sure the Select Display is set to Built-In Display.

Select the Basic tab.

Select Red and increase the brightness to 3.

Select Blue and decrease the brightness to -10 and the gamma to 0.6.

Select the Advanced tab and increase the saturation to 25.

Apply your settings. You can also save the settings in a profile and export them to a file so you can recover them in case something happens. This is an extremely good idea if you upgrade Windows as the color settings will default back after the upgrade.

There’s one more step that needs to be done. Hold down WinKey+R to open the run dialog window. Type dccw and click OK. This will open the Windows Color Calibration. (Windows 7 or higher).

Basically what you are going to do here is click the next button a few times until you get to the screen that allows you to adjust the gamma. Drop the slider down slightly from the center but no more than 1/4 of the way down. By doing this, you help improve the dark colors on the display that are otherwise washed out by the backlighting. Going too far down will make the display look dark. (Using a photo with contrasting colors as a reference helps). When you’re satisfied with the results, click next and keep clicking next until you get to the end of the calibration. (You don’t need to make any adjustments to the brightness/contrast/balance settings). If desired, you have the option to run the ClearType Text Tuner, which helps improve readability.

Now your faded blue display is a thing of the past!* If you need to make adjustments, you can repeat these steps and tweak the levels to your liking. You can also return the display’s brightness back to where you had it before.

*These adjustments do not apply outside of Windows.

NOTICE: The following has been tested with a HP & Compaq machine, both manufactured in 2003. Later years and systems with Windows Vista/7 most likely won’t work due to software changes.

IMPORTANT! For the following to work, the computer MUST have the original recovery partition from the factory. Recovery partitions created from a recovery disc do not include the additional files needed for disc creation and will display a “partition not found” error message when the CD creator program is launched.

If your HP or Compaq system has a recovery partition, you are usually notified to create a set of recovery disc in case of hard drive failure or corruption. However, HP permits the user to create only one set of recovery disc due to licensing agreements. If you lose your recovery discs or acquire a used system that already has a set made, your best bet is to contact HP and hope that they have recovery discs lying around somewhere in their factory. Or you can try this little trick that allows you to create a second set of recovery discs.

The first step requires you to unhide hidden files and folders:

  1. Start Windows and open the Control Panel.
  2. Open the Folder Options applet and select the view tab.
  3. Select “Show hidden files and folders” and uncheck “Hide protected operating system files”.

The second step requires you to delete a file named HPCD that is found in two locations:

  • D:\ (Recovery partition)

Tip: You may have to right-click on the recovery partition and select open in order to view its contents.

Once the file has been deleted from the above locations, run the Recovery CD creator program. The program should now permit you create a set of recovery discs.

HP Pavilion and Compaq Presario systems, those sold in 2004 that came with an AMD Athlon XP processor, may have an audio issue with the integrated Realtek/VIA audio controller when using certain programs or applications.

The problems include:

  • Popping or clicking sound while playing audio
  • Windows Media Player playing audio about 1 second in advance at the beginning

The motherboard these systems uses is a ASUS A7V8X-LA, It can be identified by the large “A7V8X” text between the PCI slots. The sound hardware on these boards is branded as Realtek, but uses a VIA controller. Windows Device Manager displays the sound hardware as Realtek AC’97 Audio for VIA (R) Audio Controller.

Updating the drivers for the sound hardware doesn’t fix the problem. In order to fix the problem, you will need to use a driver version older then what you currently have installed. A good example of the phrase “newer is not always better”.

You will need to obtain version of the Realtek AC’97 Audio for VIA (R) Audio Controller driver. Luckily, you maybe able to find it if you are using the OEM copy of Windows XP that came preloaded with the system.

Go to the HP folder located in the C: directory. The folder is hidden by default, so you would either have to show hidden files or simply type C:\HP in the address bar. Once there, you should see a folder labeled drivers. Open the drivers folder and you should find a folder labeled audio_Realtek_5.10.00.5570. Open that folder and and check for files. If files are present, uninstall the current Realtek AC97 Audio for VIA (R) Controller driver and right-click on Alcxwdm.inf and select install. Once the drivers have been installed, reboot the computer and see if the above problems are solved.

If you find a version older than the one mentioned here, you should be OK, but I don’t recommend using a version higher than because it may not solve the above problems.
