Preparing to Troubleshoot your Notebook
Test the AC adaptor, power cord and battery pack if you see no LED lights or the display remains black when you attempt to power on the laptop. These symptoms are an indication of a power supply problem. Switching the AC adaptor, power cord and battery pack with components that you know are not defective is an effective way to test for power supply problems. Contact a technician if there is no battery or AC power to the notebook.
Perform additional diagnostics if you hear beeping sounds during start up of the laptop or if you see LED lights blinking but the operating system fails to load. If you are familiar with beep codes and Postcodes, perform the specific diagnostic or task associated with the code. Contact a technician if you need additional assistance.
Examine your display, drives and external devices, if you observe error messages on a black screen during the boot process. Look for incorrect connections, device failures or conflicts. Visit the HP and Microsoft websites for specific instructions concerning the displayed error messages and follow all instructions provided for the resolution of the problem. Continue to the last step for using your recovery disk if you still have unresolved problems.
Remove any recently installed applications or devices if your laptop has a blue screen, fails to continue booting after the Windows logo screen appears, or if the laptop continually restarts without prompting. Review the application's documentation for specific installation and memory requirements. Additionally, some applications may have improperly installed, or a virus or other malware may infect your laptop. Scan your computer with an updated antivirus program after successfully restarting your computer.
If removal of recently installed applications fails to solve your problem, continue to the next step to restore your laptop to its original condition.
Insert your system recovery disk into your CD-DVD drive to restore your laptop to its original state if none of the previous steps solved the problem. Follow all on screen prompts to complete the recovery. Have your Product Activation Key available for insertion when prompted.
Install the latest updates and patches from both the HP and Microsoft websites once you have restored the laptop to its original condition. This will stabilise the software and prevent other start up problems from occurring. Reinstall an updated version of your antivirus software and perform a full system scan to insure that no viruses or other malware infect external media devices.
