HP Touch Screen Calibration

As a technician, you come across problems that make you just hit your head agaisnt a wall. Recently I had one of those problems where I had an HP IQ804 touch screen where the mouse would not respond correctly to where I touch at all. I’d say it was off by about 4-7 cm. I could not even click the start button because the mouse would not track my finger.

Now when I tried to do the calibration, it would not work as it doesn’t exactly calibrate the mouse more so how big your finger is. So that got me into a head against the wall scenario. While doing so I starting to poke the num lock key to look at the light flash and then I tried to pressing caps lock, num lock , and scroll lock to see if i get a pattern. On the 5th time I hi scroll lock the mouse moved.

After much step repeating and experimenting I realized that by pressing scroll lock 5 times put the screen into the ACTUAL calibration mode. So here is what I did:

  1. Press scroll lock 5 times fast.
  2. Get a small flat object like the back of a screw bit or pen top.
  3. Tap and hold DIRECTLY on the mouse pointer for about 2 seconds and release.
  4. The mouse will move just repeat those steps till the mouse goes back to the center of the screen
  5. Done! Your touch screen is now calibrated.

All that’s left is to run the other “calibration” program from control panel so your screen knows how big your finger is.

Apple Push Stopped Working

So you get to your computer and fire up iTunes to put files onto your iPod or iPhone or what-have-you and you get the error message “Apple Push Has Stopped Working”. You close iTunes re-open same problem. Detach your device and reattach but still same issue.

The Cause:

Well very clearly its the Apple Push Service not working.

The Fix:

You need to have iTunes recreate the Apple Push Service. To do this you need first !!!CLOSE  ITUNES!!! to go to;

1. My Computer(or Computer if using vista or higher)

2. C: Drive (Usually called “Local Disk”)

3. Program Files (If you are using a 64 bit version of windows it will be in Program Files x86. To check if you are using 64 bit right click on computer and go to properties)

4.Common Files

5. Apple

6.Apple Application support


So your navigation bar should look like this: C:\Program Files (x86)\Common Files\Apple\Apple Application Support.


In there you are going to be renaming the file APSDeamon to APSDeamon.BAK and agree to any prompts that may appear. When you next open iTunes it will force iTunes to recreate that file as it is no longer able to find it. Now your apple devices should work again with your computer.
