In doing so, I cracked the base case by the hinges, and the crack spread. Also over time, the laptop has become prone to overheating.

So I got a new case and with some trepidation set about unscrewing my laptop with the aid of the Technical manual and a Youtube video. I am amazed about the number of screws used to hold one of these things together.

Here it is....



The vacuum cleaner in the background was for subtly removing the dust from the fan. Also found inside the fan was a small feather....

Further on in the rebuild with screen attached... must clean the screen...



So I put it in the new case, found that one of the screws doesn't seat properly, but apart from that everything works and is much quieter.
