So now we know that part #'s KG298AA is now being sold under 463955-001 and here is the info exactly off the HP's master reference guide list: "90W AC Smart Tip power supply adapter - 100-240VAC input, 47-63Hz - 19.0VDC output, 4.74A, 90 watts, with power factor correction (PFC) - Includes smart tip dongle."

I went through and sorted the working list of laptops into something more reading friendly. If this information can help even just 1 person, then it'd be all worth it and my job is done. *Don't forget that 463955-001 is now the correct notebook ac part number for all of the laptop computer models and series below:

Compaq Presario A900 C700 CQ50-100 CQ60-100 CQ60-200 CQ60-300 CQ61-100 CQ70-100 CQ70-200 CQ71-100 F500 F700 V6500 V6600 notebooks.

HP HDX X16-1000 X16-1100 X16-1200 and HP G50-100 HP G6000 HP G60-100 HP G60-200 HP G7000 HP G70-100 HP G70-200 models use this 90W AC.

HP Pavilion dv2700 dv2800 dv6700 dv9700 dv2-1000 dv2600 dv2800 dv3-2000 dv3500 dv3600 dv4-1200 dv5-1000 dv5-1100 dv5-1200 dv6-1000 dv6-1100 dv6500 dv6600 dv6800 dv6900 dv7-1000 dv7-1100 dv7-1200 dv7-2000 dv9600 dv9800 tx1300 tx2000 tx2100 tx2500 tx2600 series models now use these laptop ac adapters.

I was also surprised to find out that this particular laptop ac adapter is also the new standard p/n for HP Mini Note and HP Mini 1100 series, HP TouchSmart tx2-1100 model and the HP G3200 notebook series.

If you need just the dongle adapter connector itself, you'll have to search and order hp compaq part number 414136-001. Bad news is the dongle is only available online (I would suggest trying eBay first) but on a good note, it is very cheap... costing no more than $5 shipped.

UPDATE AS OF 2/25/2011: Once again, HP has updated it's part number system and now this laptop ac adapter goes under 613153-001 but still is compatible with the same notebooks.

The Dell PA-12 laptop ac adapter is compatible with all these part #'s: PA-12, 1X917, 310-3149, 310-4408, 310-7697, 310-7251, 310-2860, F7970, PA-1650-05D2, 5U092, PC531, 00001, NF642, 310-7696, 310-3399, 310-6325, 310-6557, UC473 310-7712, 310-2862, 310-4002, XD802, 310-7866, HF991

What that comes down to is this Dell PA-12 laptop ac adapter is compatible in these Dell laptops:
Dell Inspiron Series: 300M, 500M, 505M, 600M, 640m, 700M, 710M, 1420, 1501, 1520, 1521, 6000, 6400, E1405, E1505 | Dell Latitude Series: 131L, D400, D410, D420, D430, D500, D505, D510, D520, D530, D531, D531N, D600, D610, D620, D630, D630N, D631N, D800, D810, D830, D830N, X300 | Dell Vostro Series: 1000, 1400, 1500 | Dell XPS Series: M1210, M1330, M140.

Over time I noticed that the 2 most common part numbers that I do come across with these specific laptops were 239704-001 and 239427-001 which is a "HP Compaq AC adapter (65 watt) - 110-240VAC input voltage, 50-60Hz, 2.4A - 18.5VDC output voltage, 65-watt - Requires a separate 3-wire AC power cord with C5 connector".

Also Compatible with: HP Compaq Business Notebook PC nx7000, HP Compaq Business Notebook nx7010, HP Pavilion zt3280US notebook PC (US). Because this laptop power adapter has been used for so many hp and Compaq computers over the past few years... this power supply is the same and compatible with hp spares P/N: 101898-001, 101880-001, 146594-001, 159224-001, 163444-001, 179725-003, A265, AC-C14, 285288-001, LPACQ3, PA-1651-02C, PP1006, PPP002D, P-0K065B13, 39427-001, 239427-003, 239704-001, 265602-001, 387661-001, 209126-001, 209124-001, 120765-001, 338136-001, 386315-002, 375055-001.

DC359A and DL606A are the most recent HP Compaq 65W Laptop AC Adapter Part Numbers and was made by HP and Compaq for the following list of laptops PC's such as the Compaq Presario L2000, 2200, X1000, M2000, V2000, B3800, V4000, HP Pavilion dv1000, dv4000, ze2000, zt3000, zt4000, ze4900, ze5000, N620c, tc1100, nc4000, nc4010, nc4200, tc4200, nx4800, nx5000, nx5100, nc6000, nc6100, nx6100, nc6105, nx6105, nc6110, nx6110, nc6115, nx6115, nc6120, nc6220, nx7000, nx7100, nc7200, nx7200, nc8000, nw8000, nx9000, Compaq Armada 110, Armada E500, Armada E500S, Armada E700, Armada M300, Armada M700, Armada V300 and Compaq Evo N110, Evo N150, Evo N400c, Evo N600c, Evo N410c, Evo N610c and then some.

WOW, what a long and confusing list that was to organize even for myself but now it should be self explanatory to anyone reading this. If you need help with anything, I am only a e-mail away and really enjoy the feeling helping others out with any computer problems that may arise. Until next tomorrow, goodnight.

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.

After much research and getting confirmation by Dell, these PA-3E can go under any of these part numbers: PA-3E, PA3-E, WK890, Y807G, 330-1826, Y808G, 330-1825, 330-1828, D094H, 330-1827, C120H, CM889, FA90PE1-00, DA90PE1-00, ADP-90VH B, WK890.

On a original dell laptop ac adapter you will find the following specs: Voltage: 19.5V and output power 90W ~ 4.62A. *Most of the notebooks using this part number require a unique 3-prong type of power cord which is supplied with the part when you purchase it from any company.*

Here is a more extensive list of compatible notebook computers that can use the PA-3E:
Dell Latitude E4200, E4300, E5400, E5500, E6400, E6400 ATG, E6500, XT2, XT2 XFR series. The Dell Precision M2400, M4400 and Dell Studio XPS13, 15, 1535, 1536, 1537, 1555, 17, 1735, 1737 series. Also don't leave out the Dell Vostro 1310, 1400, 1500, 1510, 1700, 1710 and Dell XPS M1210, M1330, M140 laptops.

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.)

I told you once that “wherever I find myself, I can adapt”, apparently you took that to mean it’d be no problem for me if we moved into a tree house in a remote corner of the HP Republic of the Compaq Jungles to live out your dream.

Now, I admit tropical living has its charms. (There’s always a new aroma on the air and I'd never be able to experience this back home... I've never seen so many brightly colored transforming animals before!)

But when I said “I can adapt” all I really meant was that I had a couple extra KG298AA 90W Smart AC laptop adapters for my notebook which I keep one in the car and the other at work. So, you know, if I was at Starbucks or something important! - I could do a little emailing or get my tweet out without worrying about my battery dying and my coffee from getting cold. I never have to leave Facebook either, I mean what doesn't this adapter do?

Funny, now, to think that a computers battery charge was ever even on my top thousand worries! Since we’ve lived in Compaq Jungles, I’ve been at robbed four times, I’ve suffered an animal trampling, and I even had a close call with an active volcano on what was supposed to be our “romantic anniversary picnic” as I’m sure you’ll remember.

Hans, I know a little something about compatibility. You know the notebook PC I had back home? That 17" HP laptop you bought
for me? Well, you should have seen it the KG298AA#ABA, 239428-001, 239705-001 plugged into one. That was compatibility, right there. After thinking back on it now, I don’t know why I couldn’t see that we just didn’t have it.

I’ll be gone by the time you read this, Hans, If you read this. All I could find to write with was a stick dipped in the crushed bodies of these weird purple beetles that seem to get into everything.

But even if you never read these words, Hans, I’m sure you’ll understand my decision. I can’t handle this life. I’m going back to what I used to have... to my old job, my old apartment, my old trust worthy HP Smart 90W adapter, the whole dang show.

I know I’ll never forget this time we spent together, though I’ll sure try. And I hope you find your Compaq blood roots. Hans, I really do. And when you do, I hope he tears you into pieces and devours you because now I lost my Facebook top 10 position and you know how I am with being #1.

Good To Know Important Information on the HP 90W Smart AC Adapter:

1. Enjoy the flexibility and convenience of having an extra 90W Smart-pin AC Adapter for your notebook, whether you’re at home, in the office, or traveling. You can leave one at your desk and keep the other in your bag for quick plug-in, no more climbing under the desk to plug and unplug.

2. You are actually saving energy over time: the Smart-pin technology reduces power consumption when the maximum adapter rating is reached. Recharge the battery, whether the PC is on or off, when plugged in an electrical outlet. Protect your system from surges with the built-in surge protector.

3. Connects to most non smart-pin HP and Compaq notebooks with a included dongle adapter which makes this ac adapter the most popular and used laptop accessory for the past few years!

This laptop ac adapter is compatible with a whole assortment of machines which I was nice enough to list below:

Do not fear Compaq Presario users as I didn't forgot you guys either. Compaq laptops which use this specific laptop power supply would be: CQ40, CQ45, CQ50, V3000, V6000, M2000, V2000, V4000, V5000, 2200, C300, C500, C700, C900, F500 and F700 notebook PC's.

HP has done it again; new updated replacement part numbers for the new year. The KG298AA was changed to 613153-001 which both are identical besides the difference in PN's.
