Replacement AC Adapter?

My AC Adapter for my Dell e1505 recently stopped working, and wouldn't you know it 1mth after my 1yr Hardware Warranty expired

I needed a replacement FAST as this is my MAIN computer and I can't have alot of downtime (work). So after arguing with Dell Tech Support for a while (which got me no where), I turned to eBay and found a replacement HERE.
I contacted the seller and made sure that if I paid the $35 shipping I would receive the adapter the NEXT day. He confirmed and indeed the adapter showed up the next day.

Once I opened the UPS box I noticed this adapter was different from my original adapter. It was larger and used a 3-prong wall plug vs. the original 2-prong. So I compared the stats on the back of the two adapters and here is what I found.

Original Adapter:
65W AC Adapter
PA-12 Family
Model No. LA65N50-00
Output DC: 19.5V 3.34A

New Adapter:
90W AC Adapter
PA-10 Family
Model No. PA-1900-0202
Output DC: 19.5V 4.62A

Two things concerned me here...
1. The new adapter uses 25 extra watts (90w vs. 65w)
2. The new adapter outputs 1.28 extra amps (4.62 vs. 3.34)

So I was hesitant to plug the sucker into my e1505 fearing that I would fry my laptop. But I did anyways
And it seems to be working fine

My questions:
1. Is it safe to be using this adapter?
2. Because of the extra amperage output does this mean that my laptop will charge faster?

Thanks in advance,

thats not the right adapater for your laptop, but it should work.

that is the adapter i have for my 1210 i believe, a 90watter. It should hurt your laptop, itll just use 60 watts, cause thats all it needs.

i plugged in a i6000 to a pa-12, and it was fine. the 90w adapter is more for the laptops that need the extra W, the 17xx, and xps lineup.

you should be good to go. the laptop should charge in the exact same time with the 90 as it did with the 60. The laptop will only take what it wants power wise from the adapter, so no faster charging for you

 

The voltage is the same and the notebook will only draw the power that it needs.

And it is possible that your battery will charge a bit paster when the notebook is running.

The downside is a bigger and heavier PSU to carry around.

you mean SHOULD NOT right? I hope it doesn't hurt my laptop
Thanks kgeier82,

Has anyone else had a similar experience with a replacement AC Adapter for your Dell Laptop?

 

:BUMP:
anyone?

 

This is interesting as the E1705 I am working on has the same adapter rated at 65 watts,as your original adapter on your E1505. The three prong on the power-in cord are nothing to worry about as the third prong is a grounding lug for the unit, so you don't get shocked in case of a short circuit in the supply. As to the 25 extra watts, this should be no problem as I have consistently seen that all the Dell E series laptops receive the upgrade to a 90 watt unit. The E1705 has right on the back of the laptop that the power supply number is a PA-10. If your E1505 says PA-12, then that is the supply which is the original, and might explain why I have a PA-12 for the E1705. Somebody got the wrong supply for my laptop. As far as any damage or problems running your unit on the PA-10 it seems unlikely, and that is why all the upgrades are to the PA-10.

 

Dell website shows both a 65 and 90 watt adapter option ... so I wouldn't worry about it at all and I think the PA-10 and PA-12 are equivalent. As I understand the PA-10 90 W is usually supplied with the larger 9-cell batteries. That is what I have for my Inspiron 1420.

 

90W AC adapter is an optional upgrade. You should be happy with it. It has ~30% higher maximum output, but your laptop will only draw necessary currents at the same voltage.

 

Thanks for clearing that up for me Bill
So Far So good w/ my new adapter

 

I would've just went with an original Dell AC Adapter. I'm sure they would have that on eBay. I bought a 9 cell battery from eBay a few months ago, a genuine dell one too for $65!

 

your new power supply is designed for your family of computers, its just that some of the laptops with beefier cpu's and gpu's draw 90 watts. As long as voltage is the same, it will only draw as many amps (and in turn, watts) as it needs. You probably paid a little more then you needed though.
