A:Answerthe plain and simple answer is yes. This RAM is low voltage which means that instead of using 1.5v it uses 1.35v thats the key and the answer to your question. That's DELL standard voltage for low power laptops.
A:AnswerHello Gray 1988. Just to be sure you have the correct RAM, google the make and model of your HP Laptop. I cannot say one way or the other what you have is compatible or not from the description given by best buy. The specs show two slots..........one permanent and one free slot, but did not give the RAM stick identification. Plan "B" would be to check with the GEEK squad. Sorry I can't help any further than that; I don't want to give bad info.
A:AnswerYes. I bought a used Late 2012 Mac mini that had a single 8Gb SODMM. I bought this and slapped it into the 2nd slot and it's been working fine.
