ac adapter - can i use a different one if it fits ?

[tanyahimanen]

i have an hp 15-bw028ca notebook. i need to recharge the battery. the ac adapter that it comes with is a 19.5v 2.31a 45w with a 4.5mm barrel. this is my 4th hp laptop, so i still have the three old hp adapters. i need to know if i can use them with this laptop even if the specs are not exactly the same. they all fit the 4.5mm barrel. one adapter is 19.5v 3.33a 65w and the other two are 18.5v 3.5a 65w. do i need to buy yet another ac adapter or what ?

The one with the same voltage is fine. The laptop will only take the power it needs so OK to use an adapter with same voltage, higher watts but same connector. The 18.5 volt I would be cautious. Do you have the part numbers on those 2?

WoW that was fast !  i had already taken pix of all three, (to enlarge the text because my eyesight is failing me), so i am uploading it here as well as typng it out. the info is as follows:

the first and second ones are hp part # 608425-002 (replace with hp spare 609939-001), 18.5v 3.5a 65w. then, the third one is hp part # 709985-003 (replace with hp spare 710412-001), 19.5v 3.33a 65w.

The top 2 are the same 608425-002. From pictures I can find it is an older kind with a large round barrel and a center pin. Not sure how you can use them. The bottom one has a barrel plug like this, right?

If your factory adapter also has this 4.5mm plug with blue tip you can use the one in the bottom picture.
