Example: VIN: = 18VDC or 18V DC
NOTE: The specific notation “VDC” might not be indicated, Instead the following international
symbol shown might be used 18 .
In some cases you may determine the desired voltage is between whole numbers such as 15.5VDC.
In this case use the next higher voltage setting (16VDC)

Use the diagram shown above to verify that you laptop uses “center positive” polarity as most all
laptops use “center positive” polarity. Do not use the LAC120 if your laptop shows “center negative”
polarity.

Do not force the tip in, it should slide in as easily as your original did. If it does not fit easily please
verify you have the correct tip listed in our reference. Connect the selected adapter tip to the end of

TROUBLESHOOTING
Some laptop computers have power supplies in excess of this power adapter (120 Watts).In
most cases, the higher rating is used to both charge a completely discharged battery and
power the laptop at the same time. This power adapter can be used for such applications, but
it is recommended that the computers battery be fully recharged before using the adapter to
operate the laptop.

NOTE: This power adapter can power, but may not be able to charge battery for some Dell
®
models.
If the indicator turns off while the power adapter is in use, this indicates that the power
requirement of the device is beyond the maximum output of the LAC120 and that
overload/short circuit protection has been activated.
NOTE: It is normal for the LAC120 to be warm during use.
