Question about HP Pavilion dv9000z Notebook
As the issue is not clear whether the keyboard doesnot type the keys that are pressed, I recommend you to try typing in different applications like Microsoft Word, Notepad etc so that if the same thing happens with all the applications, the issue should be with the Keyboard.
However, before coming to a conclusion, I recommend you to try connecting a USB Keyboard to the Notebook and see if the same thing happens with it an all applications like Word, Notepad etc.
If the same thing happens with the USB Keyboard, the issue can be with the Keyboard Drivers which will be common for both the Notebook Keyboard and any external keyboard connected.
You can try to reinstall the Keyboard Drives in the Notebook from the Device Manger :
Open Device Manager by following the instructions....
Press the Start Menu and R key to get the Run command prompt.
In this, type devmgmt.msc and click on OK.
This will give us the Device Manager window.
In this, click on the + mark next to Keyboards which will display two entries.
Right click on Standard 101/102-Key or Microsoft Natural PS/2 Keyboard and select Uninstall and click on OK in any window that appears.
This will uninstall the Keyboard Drivers from the Notebook.
Restart the Notebook once the process is completed.
The Keyboard Drivers will be reinstalled and the issue should be fixed if it is with the Drivers.
If the issue is with the Keyboard Hardware, the issue remains and you may have to get the Keyboard replaced by contacting HP if it is under warranty.
If the Notebook is out of warranty, get the Keyboard replaced through any HP Authorized Service Provider like Best Buy, Comp USA or Radio Shack stores in US.
