1. Be sure that the computer is plugged into a working AC outlet.

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.

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.
