Video card screwed on presario v3000 (known issue)

The mainboard or motherboard is the main PCB in the laptop. It is the most difficult component to replace because you must completely disassemble the laptop to remove it and properly install the new one. Take the battery out, ground yourself and discharge the laptop by pressing the power button for a few seconds. Most laptops start dissassembling by removing the power button/led panel above the keyboard, and then removing the keyboard, de-attaching the LCD screen assembly. And then flipping it over and removing screws on the bottom, then the laptop will split in two peices, the top part of the chassis and then the bottom half which is where the motherboard will be attached. If you decide to continue organize your screws, label them or take pictures to help you get it back together. Hope this helps you get started.
