IMPORTANT INFORMATION FOR THIS HP LAPTOP POWER SUPPLY: HP has done it again; new updated replacement part numbers for the new years ac adapter laptop lineup. If your having trouble finding 239704-001... that is because the new 2011 part number is 613149-001 which specs are 100% identical besides the difference in PN's.

This laptop ac adapter was especially designed to meet the needs of everyday power demand and also joins up with optional accessory adapter tips to also charge your cell phone, digital camera and so many other mobile devices at the same time as your charging your notebook. I'm glad they built in short circuit protection with auto recovery to prevent damage to laptop ac adapters itself and the electronic it's hooked up to.

When you first open the box you see that Targus includes 10 interchangeable tips which part #'s are 102, 104, 201,202, 203, 204, 205, 206, 207, and 209. The book inside has the master list of what tip to use for each device.

Here is the important information taken from the retail box (well, what I think is important LOL).
Power: 90W Max
Input: 100-240V ~ 3A 50/60 Hz
Output: 15-24V 6.5A 90W
DC Auto/Air Adapter Input: 12-30V 10A
DC Auto/Air Adapter Output: 15-24V 6.5A

Also on the Targus APM62 universal ac adapter outside packaging are the compatible brands that this can be used by just switching tips. Way to many to list but the major brands I see are Acer, Asus, Compaq, Dell, Fujitsu, Gateway, HP, IBM/Lenovo, Motorola, Samsung, Sony, Toshiba and the list goes on and on.

The PA3715U, PA3468U and PA3432U 75W universal adapter works with a wide range of Toshiba notebooks and since it's universal... it means you can use this one around the world with the appropriate plug adapter depending on which country you are traveling to.

This Toshiba Global AC has the following ratings on the product - "75 Watts, 120V-240V/ 50-60Hz (Universal) input voltage with a 19V x 3.95A output voltage".

These same 3 part #'s work in the laptops listed below: Toshiba Satellite A100-S2211TD, A100-S8111TD with Intel Celeron M Processor only, A100-ST3211TD, A105-S101, A105-S101x, A105-S171, A105-S171x, A105-S2xxx, A105-S271, A105-S271x, A105-S361, A105-S361x, A105-SP461, L45-S7409, L45-S7419, L45-S-7423, L45-S7424, M60, M65, T115, T135, U300, U305 and Satellite Pro T130 and Tecra M8 series notebooks.

*You should absolutely note that PN: PA3715U-1ACA is the direct replacement for PA3468U-1ACA and PA3432U-1ACA models.)

This laptop ac adapter I found under many part numbers such as NX061, HR763, PA-1650-02DW, LA65NS2-00, YR733 and 310-9249.

The first thing to consider in a laptop ac adapter is the voltage. The easiest way to check this is to turn the computer over and see if there is a voltage listed anywhere on the bottom of the machine. A sticker may be affixed with this information and other similar laptop specs listed. It should be a number with a V such as 19.5V. This information is also available on the original adapter, if it is available to you. If you do have a current working notebook ac adapter then your best bet is to buy the same exact part number that is on the laptop ac adapter itself.

The second thing to look for is the current output needed for the laptop ac adapter. Just for example, it may say something like 4.7A, 950mA etc. This number will ensure that the power going to your machine will be acceptable and keep it operating normal. Not paying attention to either of these numbers could cause the electrical systems in your laptop to malfunction and stop working altogether.

Once these two issues have been settled, the other important step is simply to make sure the laptop ac connection fits the port in your notebook PC. The voltage and output current of the laptop ac adapter will not matter if it is not able to be connected. I suggest and think the best way to go is buying a replacement laptop ac adapter with the identical part number directly from the manufacturer. Another thing to consider is whether you want an AC laptop adapter or DC adapter. An AC adapter is made to be plugged into any standard electrical outlet such as those in a home or office. The DC adapter is made for automobile use.

HP's system shows this information when looking up this part number - "AC Adapter : AC adapter - 2-wire, 60 watt - Requires separate 2-wire AC power cord (2-prong)". I will make it easier, the voltage specs on this ac adapter is 19.0V and 4.74A, 60W Output | Input 100-240V.
