Power supply


Post by Siles » Thu Mar 16, 2017 3:02 pm

I have a Dell power brick rated at 19.5V, 6.5A. Is this safe to use on an HP DV9715nr calling for 18.5v, 3.5a?

Short answer: maybe.

There is more to it than just voltage and current. Will the connectors fit? Is the polarity correct? AC vs DC? Some laptops require special connectors that carry signalling information. ...

Don't just plug it in and hope for the best, it can ruin your day. Do some research on the exact make and model of each power brick and laptop and compare them.

hello Siles
Nice laptop; are you planning to travel?
Smart-chip. Those parts you have are likely of smart-chip in the powercord era of Dell and hp. get a hp power supply to charge a hp laptop. Dell cord is the only thing that will charge a Dell. sometimes the plug, of equivalent size they are, will power but not charge. The power supplies that have adapt to many tip sizes can provide the "special connectors that carry signalling information," as linmx expressed, included in the kit.

I agree with what linmx said.

When you try it you should check information and take action before you do it.

And the most safe way is that you just need to change a same one.

Check here http://www.parts-dell.cc,the power supply in the store is good and cheap.

Personally I would not use an adapter that has a different voltage, not sure if 1V is enough to ruin your laptop, but if I were you I would not take the chance.
