If Something Goes Wrong
Resolving a hardware conflict
❖ The Resources tab, which lists resources assigned to the
monitor, optional external optical drive, optional external
diskette drive, and other power-using functions. This tab
does not appear if the device is not using resources.
❖ The Driver tab, which displays the drivers being used by
the device. This tab also provides options for updating the
driver or rolling back the driver in case the new version is
causing a problem.
The tabs that appear in the dialog box vary from one device to
another.

Power and the batteries
Your computer receives its power through the AC adaptor and
power cord/cable or from the system batteries (battery, optional
secondary battery, and real-time clock (RTC) battery). Power
problems are interrelated. For example, a faulty AC adaptor or
power cord/cable will neither power the computer nor recharge the
batteries.
Here are some typical problems and how to solve them:
The AC power light does not come on when you plug in the
AC adaptor and power cord/cable.
Make sure the AC adaptor and power cord/cable are firmly plugged
into both the wall outlet and the computer.
If the AC power light still does not come on, check that the wall
outlet is working properly by plugging in a lamp or other appliance.
The AC adaptor and power cord/cable work correctly, but the
battery will not charge.
The battery does not charge while the computer is consuming full
power. Try turning off the computer.
The battery may not be inserted correctly in the computer. Turn off
the computer, remove the battery, clean the contacts with a soft dry
cloth (if necessary) and replace the battery. See “Removing the
battery from the computer” on page 98.
The battery may be too hot or too cold to charge properly. If you
think this is the probable cause, let the battery reach room
temperature and try again.
