1.Determine the required output voltage setting of the power

adapter by one of the following four methods: .

Refer to “Compatible Computers” on Page 11 for voltage, tip color, and polarity settings.

Note the voltage indication marked next to the input jack on the device to be powered. Example: Vin = 18V DC or18V DC.

Review the power or ID plate on the device to be powered. Look for the word “INPUT” followed

by a number and V DC. Example:INPUT: 18V DC. ±

Review the power or ID plate on the AC power adapter usually used to power the device. Look for the word “OUTPUT” followed


by a number and V DC.

Example: OUTPUT: 18V DC.

If the power adapter or computer indicates a voltage range, use the voltage closest to the mid-range.Example:OUTPUT: 10–16V DC; set the power supply to 13V DC.

In rare cases when the voltage setting is between whole numbers, such as 15.5V DC, use the lower setting first (15V DC). If the device does not seem to operate properly, readjust it to the higher value (16V DC).

2.Use a flat-blade screwdriver to rotate VOLTS 12/13/14/15/16/17/18/ 19/20/21/22/23/24to the desired output voltage.

• Green (Q) — 6.3 × 3 mm

Yellow (T) — 6.5 × 4.3 mm with 1.9 mm pin

Orange (H) — 3.4 × 1.3 mm

1.Refer to “Compatible Computers” on Page 11 or examine the output connector of your computer’s AC adapter and compare it to the Adaptaplugs supplied with your power adapter.

2.Select the Adaptaplug that resembles the original plug and test it by temporarily inserting it into the device to be powered. The center contact or pin must be the correct size to ensure proper electrical contact. If it is too small or large, additional Adaptaplugs are available from your local RadioShack store.

3.Connect the Adaptaplug to the output socket at the end of the power adapter’s cord.

If the tip on the device’s power jack is positive, align + (positive) marked on the Adaptaplug toTIP marked on the output socket. If the

tip on the device’s power jack is negative, align (negative) toTIP.



If you use the special Dell plug, align TIP on the Dell plug withTIP marked on the output socket. ±

If the polarity symbol is not displayed on the device to be powered, it might appear on an ID plate on the computer power supply or the original power adapter (see “Compatible Computers” on

Page 11).


Selecting the Adaptaplug



Save your data frequently! If you operate your notebook computer after removing its internal battery, an interruption in power might result in an immediate computer shutdown and possible data loss. Such a power interruption could be caused by accidentally disconnecting either end of the power adapter.

the supplied AC power cord into the AC jack on the adapter. Plug the other end of the AC power cord into a standard AC outlet. The green indicator lights.

After making the connections described above, check the power adapter’s cord. If it is hanging loosely or if it is positioned so that it could be damaged, wind the excess cord around the adapter — the large grooves on the top and bottom of the adapter help hold the cord in place. When the cord is the length you want, slide the cord clip down the cord until it is next to the part of the cord you wrapped around the adapter. Then, press the clip over one piece of the wound cord to hold the cord in place. .


Some notebook computers have power supplies in excess of the rating of this power adapter (80 watts). In most cases, this higher rating is used to both charge a completely discharged battery and power the computer at the same time. This power adapter can be used for such applications, but it is recommended that the computer’s


battery be recharged before using this adapter to operate the computer. .

You should remove your computer’s battery only under the following conditions:

The computer automatically shuts down while you try to power it with the AC adapter.

The computer’s rating label states that the computer requires greater than 80 watts and the computer’s

battery is completely discharged.


In the unlikely event of insufficient power, you may encounter slower battery charging time or automatic shutdown of the power adapter. In case of automatic shutdown, try one or more of these steps to reset the adapter: .

Completely recharge the battery before using the computer. Use the power adapter to charge the battery, but do not operate the computer during charging.

If the battery is easily removable, remove it from the computer to eliminate the power requirement for recharging.


Except as noted for notebook computers (see “Compatible Computers” on Page 11), the power

adapter’s 80 watt rating must be equal to or greater than the requirement of the device to be powered.


If the computer’s battery is fully charged, do not remove it.


Always turn off the computer before you remove its battery.

Be careful when removing your computer’s battery because some laptop computers do not have batteries designed for frequent removal.





If the indicator turns off while the power adapter is in use, the output current is beyond the specification and the overload/short circuit protection activates. Disconnect the adapter from AC power, then unplug the adapter from the device. Reconnect the power adapter to the AC power. If the indicator still fails to light, take the adapter to your local RadioShack store for assistance. If the indicator is on, reconnect the adapter to your laptop. If the indicator turns off, your laptop is exceeding the 80W rating of the adapter (see “Troubleshooting” on Page 8).

The power adapter can be used to charge the battery in your notebook computer by connecting it to the computer with the battery installed, and leaving the computer turned off. .


Keep the power adapter dry; if it gets wet, wipe it dry immediately. Use and store the power adapter only in normal temperature environments. Handle the power adapter carefully; do not drop it. Keep the power adapter away from dust and dirt, and wipe it with a damp cloth occasionally to keep it looking new.


If your power adapter is not performing as it should, take it to your local RadioShack store for assistance. Modifying or tampering with the power adapter’s internal components can cause a malfunction and might invalidate its warranty.
