Helpful Hints
After you become familiar with the troubleshooting steps, use the helpful hints before running diagnostics and
troubleshooting.
At startup
These steps provide simple, useful checks that you can perform when troubleshooting.
TIP: If you have installed an operating system other than the factory-installed operating system, go to
http://www.hp.com/go/quickspecs and verify that it is supported on your system.
1. Be sure that the computer is plugged into a working AC outlet.
2. Be sure that power is connected to the docking station if you use a dock.
3. Be sure that the AC adapter light is on.
4. Be sure that the AC adapter is connected when you update BIOS to avoid BIOS corruption.
5. Be sure that the computer is turned on, the rear power light is solid white (connected to an external power
source), and the front power light is solid white (normal operation).
6. Remove all optical and flash drives from your system before turning it on.
7. Be sure that the boot option is set to a working operating system drive.
8. Be sure that externally connected monitors are turned on and their power lights are on. Not all monitors
are equipped with lights to indicate their functionality.
9. Turn up the brightness and contrast controls of a display or external display device if the screen is dim.
During operation
The following steps provide simple, useful checks that you can perform when troubleshooting.
1. To wake the computer:
a. Press the power button or any key on the keyboard.
b. If the system remains in the Sleep (Windows), Suspend (Linux), or Hibernate state, shut down the
system by pressing and holding the power button for at least 4 seconds.
c. If the system does not shut down, unplug the power cord, wait a few seconds, and then plug it in
again. Then press the power button again to restart the system.
2. Look for blinking lights on the computer. The blinking lights could be error codes that help diagnose the
problem.
3. Check all cables for loose or incorrect connections (external devices, power cords, dock, and so on).
4. After installing a non–Plug and Play expansion board or other option, reconfigure the computer. For
example, if you upgrade to a solid-state drive, you might have to reconfigure the boot order.
5. Be sure that all required device drivers have been installed. For example, if you have connected a printer,
you must install a printer driver.
6. If there is a network connection issue, plug another computer with a different cable into the network
connection. There might be a problem with the network plug or cable.
