Do-It-Yourself Laptop Batteries Repair
For example, the same hard drives and random access memory chips work in laptop batteries from Apple Macintosh computers to Dell to Sony. Three basic components that may prevent a laptop from powering up are the motherboard, RAM chips and hard drive. Hard Drive and Motherboard There really is no way to fix a totally crashed hard drive at home. Hard drives are built in "clean rooms" designed to keep any dirt and dust away from the manufacturing process. Once you open the computer---there are instructions for individual brands across the Internet---you unseat the hard drive, which usually is fitted to some kind of cradle. The standard laptop hard drive has a rubberized connector bar at one end with a large array of gold pins. Gently pry this connector bar away from the hard drive holding the hard drive and rocking the bar with your thumbs. Get a new laptop hard drive of whatever capacity you want and connect it.
