AC adapter compatibility question

[ Edited ]

I have a new DV5t laptop under the tree. I understand it comes with this adapter: KG298AA#ABA (HP 90W Smart-pin AC Adapter) and that the adapter is prone to break.

 

I have been offered a couple of HP adapters that are 90w, with the following HP part number: 393955-001. They are NOT Smart-Pin adapters but the other information appears to the same.

 

Here's my question: Will the non-Smart Pin adapters power a device with a SmartPin input? I am highly reluctant to spend $50 apiece on adapters your own Web site tells me will break.

 

edit: I found the other part number for the non-Smart Pin adapter: EH642A#ABA

Re: AC adapter compatibility question

I don't think it will work because the barrel/pin is different....and it's probably not worth the risk of damaging your notebook.

Re: AC adapter compatibility question

I agree it's not worth the risk - I don't want to damage my new computer. But I thought it was worth asking, due to the reported problems with the original-equipment adapters.

Re: AC adapter compatibility question

I would like to know if a dell wall adaptor would work, it has the same exact plug on the computer side. but its 19.5 volts instead of 18.5 volts. but I figure the wall utility voltage varies from 115 to 130 vac rms so what will one volt hurt on the pc end

 

just wondering, i would never try until I was sure, my work laptop is a dell so there is always a PSU plugged in at my home desk.

Re: AC adapter compatibility question

no the dell is 90 watt, the HP/Compaq is 65 watt.
 
not sure why that would matter since its voltage regulated. its just "X" volts then whatever amps is needed to keep the voltage, up until you run out of watts, right? lol
 
While I have never, and will never, use an unapproved PSU for the computer, it is just a curious observation that the plug is so similar.

Re: AC adapter compatibility question

I've actually got a similar type of query:

 

the AC adapter for a nx7400 recently popped and i asked the suppliers to send me a compatible replacement. i received a 90W, 19V - 4.74A from them, but the specifications on (underneath) the laptop reads 18.5V - 3.5A. I know the stronger current won't make difference since the notebook will draw only what it needs, but will the difference in voltage (though very minor) make an impact?

 

I know 0.5V really isn't much, but you know how sensitive computer electronics are, especially laptops....

Re: AC adapter compatibility question

The original part # that you need to replace your AC Adapter is: 463958-001

Any way you can use a 391172-001 as replacement.

I found one at impactcomputers.com and the cost is 50$

 

Best regards

 

PS. DO NOT use a Dell AC adapter, the barrel/pin looks the same but there is some differences
