The battery on my laptop has been malfunctioning for a couple of years, and now it’s completely gone. Before I ordered a new one, I wanted to be sure to order the right one the first time.
I found this link on the HP Support Website, and was one click away from getting the information I needed. The site identified my laptop, and listed all the information I wanted.
HP Pavilion dv7-6b55dx Entertainment Notebook PC
I knew I had the HP Pavilion Entertainment Laptop Dv7, but I needed that “6b55dx” portion.
I went to ebay.com and searched “HP laptop battery Dv7-6b55dx,” and found several vendors selling brand new batteries for my 3.5-year-old laptop. Done.
