While troubleshooting your notebook, follow
these safety guidelines:
Never remove the memory bay or hard
■
drive bay cover while your notebook is
turned on, while the battery is installed,
and while the modem cable, network
cable, and AC power adapter are
connected to your notebook.
Make sure that you are correctly grounded
■
before accessing internal components.
After you complete any maintenance tasks
■
where you remove the memory bay or hard
drive bay cover, make sure that you replace
the cover, reinstall any screws, then replace
the battery before you start your
notebook.
If you have problems with your notebook, try
these things first:
Make sure that the AC power adapter is
■
connected to your notebook and an
AC outlet and that the AC outlet is
supplying power.
Make sure that the power cord is firmly
■
connected to the AC power adapter.
If you use a power strip or surge protector,
■
make sure that it is turned on.
Try turning the notebook on with the
■
notebook plugged in and the battery
removed, then try turning the notebook on
with the notebook unplugged and the
battery installed.
If a peripheral device (such as a keyboard
■
or mouse) does not work, make sure that
all connections are secure.
Make sure that your hard drive is not full.
