Replacing a battery is an easy thing if you have the right tools. My daughters battery was giving her fits but most places wanted you to leave the computer to fix it taking anywhere from 1 to 3 days. This way I saved some money and fixed it in 20 minutes.
The repair went great. I watched the video before I ordered the battery so I knew I could do it and then it went very easy and my daughter is back in business.
Like I said this is a very easy repair so don't let opening a computer intimidate you. I had fun teaching my daughter something and she enjoyed seeing what was inside her computer.
