Knowing how to read an Laptop ac adapter is a skill that comes in handy during a variety of home projects. You can easily match power cords to devices by comparing voltage and polarity, and if an adapter is damaged you can use the information to find a replacement.

1.Identify the voltage. Next to the word "output", you'll see a number with a "V" after it (such as 12V). This is your voltage.

2.Identify the amperage. After the volts, there will be another number with "A" or "mA" after it (such as 3A or 500mA).

3.Find the diagram that shows three circles connected by lines. The center circle will be open on one side. Whichever sign it opens to is the polarity of the tip. If the circle opens to the plus sign, it is tip positive. If it opens to the minus, sign it is tip negative.

4.If possible, compare the information from the hp 530 adapter to the device it powers.

5.Check the Input section to determine the voltage it requires from the wall outlet.

A rating between 100 and 120 volts denotes standard voltage used in the United States. A rating of 200 to 240 volts denotes voltage used in a foreign country, and the adapter will require a voltage converter to work in the United States.

Tips & Warnings

*An amperage listing of mA denotes milliamps. 500 milliamps are equivalent to 0.5 amps. AC DC adapters such as HP Compaq 2210b Adapter, HP nc8430 Adapter, HP nx6110 Adapter, HP tc1100 Adapter, HP G3000 Adapter, HP HDX X16 Adapter, HP HDX X18 Adapter, HP Pavilion dv1000 Adapter, HP Pavilion dv2000 Adapter, HP Pavilion zt1000 Adapter that have an input of 100V to 240V can be used with any voltage, but may require a country specific plug adapter. If you're going to purchase a replacement adapter, bring the device to the store with you so you can find the appropriate tip.

* Do not guess about the polarity if the diagram is unclear. Contact the device manufacturer for more information or to order a replacement. Using an AC DC adapter with the incorrect wall voltage will result in damage to the adapter and/or device.

AC Power Adapter Tips

Power Strips

# Its odd, blocky shape means an adapter will take up too much room on a regular power strip. Some power strips feature extra space for power strips. Widely available, you should have no trouble finding one at a music shop. Musicians' electronic boxes are largely powered by AC adapters.

Another item, the Power Strip Liberator, is a short AC cord that plugs into your power strip. It accepts an adapter on the other end. Its slim plug fits a socket on a conventional strip, keeping other sockets available.

Some power strips have built-in surge protection. This keeps severe voltage variations in the household AC power from harming your equipment. Power surges can damage all kinds of equipment, including adapters. Spending the extra money on this feature is worth it.

Specifications

# HP 530 AC adapters come in hundreds of sizes, shapes and ratings, but three factors count most.

Voltage: Adapters typically provide between 3 and 24 volts.

Current rating: Electronic items typically consume between 100 and 3,000 milliamps. The adapter provided with the electronic item will deliver enough current, but no more,

Plug type and polarity (the plug that goes into the gadget, not the wall): Most adapters have two-conductor plugs, some have three. You can have an adapter with the right voltage and current, but if the plug's wrong, you're stuck. Polarity also varies among different models; some have a positive internal pin with a negative outside, some have it the other way around. A multi-use adapter allows you to switch polarity, so it will work with the widest range of equipment.

Unplugged

# AC adapters consume current even when they're not powering anything. If you touch one that's plugged in, it will be warm. To save energy and money, unplug the adapter when it's not in use. If you are recharging your cell phone, note when it's full, so you don't waste anymore power than necessary.

Testing

# If you have a piece of equipment that's working poorly, the cause might be its hp ppp009h AC adapter. You can check the voltage and polarity easily with a handheld multimeter. If you're lucky enough to have an oscilloscope, use it to test the adapter. Look for excessive ripple (bad capacitors) or lack of DC offset (bad diodes). If you find anything amiss with the hp ac adapter, simply replace it with an equivalent.
