Looks good , where I can get Battery Replacement from ?
Hello! You can look at newegg com, amazon.com or ebay.com. That's where you can get a bunch of great used parts!
THANK YOU, THANK YOU, THANK YOU! I replaced the battery following your instructions. The only thing I did differently is that I couldn't get the plug out with the battery still screwed down, so I unscrewed the battery then unplugged it. After unplugging, then I held down the power key for a few seconds to discharge before plugging in the new battery and screwing it down. My computer will be like new now! Blessings to all of you at IFixIt!
I bought my new replacement battery from the store at IFixIt.com.
You're welcome! I'm glad our project could help you!
After I've ''discharged any leftover power" by holding the power button down. What do I do ? Do I leave it until the laptop turns off by itself ? Or do I hold down the power button to force shutdown ?
