Is this AC adaptor safe?

I have a dv8000t that uses a 90W AC adaptor. I bought an aftermarket adaptor with the same 90W rating, but in the Input, the Amp rating for the aftermarket is at 1.5A while the original HP adaptor is at 2.4A. Everything else except the Input looks the same.

Will this damage my computer at all or is this not a problem at all?

 

Probably not. It can't be right. Or maybe right. They might rating the power differently. You have to make sure they talk about the same 90W on same side. What is the output voltage? Taking the equation P=I*V. If the voltage is different, then it may burn you laptop.

Just use multimeter before you plug it in.

 

I would also suggest you check the voltage the adaptor gives before you plug it. If it gives the same voltage (±2 volts) I guess it is ok to try.

Can you clarify where is the "input" you are talking about ? Can you state what voltage you see on the adaptor ?

 

I guess he means the input Amp rating. Obviously 1.5A at 110V is sufficient for a 90W adapter. Use a volt meter to check the output to see if it matches the original one. I have two 90W adapter for my DV4000, the original one is listed 19V 4.75A and the after market one is 18.5V 4.9A. Both work fine with my laptop.

 

personally wouldnt risk it either way. Why would you buy one that wasnt spec'd for your model? Or go for a kensington brick that can adapt to all laptops.

 

To answer my own question, HP actually got back to me and told me it was ok to use this aftermarket product. And it's been working ok.

 

Hi All,
The input current will vary depending on the step down transformer and other components used in the adapter. The concern is the output voltage.
The output must be wihtin a volt or so of the manufactorers adapter or damage to the laptop can occur. There is a regulator circuit in the laptop I'm sure, but what its limitations are would not be a good idea to find out.
