said by signmeuptoo94:Caddy, sorry, I realize now that my statements might seem to cause one to think changing hard drives is too hard to do, but to amend, with most laptops it's pretty easy. So's changing RAM. Some are easy to change optical drives and even the wireless controller.
I don't know why you need to apologize. In reality the complexity varies a lot depending on the make and model. I have run into ones (the first Acer Aspire One, for example) which require stripping everything out, keyboard, touchpad, memory, WLAN card, antennas, etc, before you could get to the hard drive. Some poorly-designed models have cases that are snapped together using flimsy clips (in addition to screws), that are guaranteed to break upon disassembly even if you know their locations. Some even have the hard drive secured using adhesive. And more and more laptops use 7 mm tall drives that are not as common as traditional 9.5 mm tall ones. While these might not necessarily apply to the OP, they are still things to watch out for when working on portable computers.
In my experience, usually the bigger/bulkier the laptop is, the easier it is to work on.
