Your laptop was configured to support a specific motherboard (system board). When something unfortunate happens and you need to replace your laptop motherboard, start out by searching for the same exact make, model and part number on you current notebook motherboard on the internet. For example: eBay, Amazon, Google etc... are excellent starting places to find any laptop motherboard or replacement laptop part.

The main purpose of a laptop motherboard is to send instructions and commands to all the computers internal components. A laptop motherboard controls your whole laptop PC and just about everything relates back to laptop motherboards. To make it easy, essentially it's your notebook's brain which every laptop computer can't run without. The system board allows your operating system to communicate with computer peripheral devices, such as the mouse, keyboard, touchpad, 10/100/1000 and wireless network connections. Other useful features that are usually standard on laptop motherboards include expansion slots for audio sound, video graphics cards and memory module slots.
IMPORTANT NOTE: The biggest misunderstanding over replacing your laptop motherboard is the C.P.U. they use, require and speed (GHz) it supports. I personally never bothered upgrading a laptop cpu because original laptop motherboards could handle only a very slightly faster chip (for example - if you currently have a Mobile Pentium 4 2.0GHz, the most you could upgrade to would be approximately a Mobile Pentium 4 2.2Ghz. Make sure 100% that your motherboard will support your current hard drive, optical drives and has all the essentials needed for all your peripherals.
