Being confident alone is not enough to help you repair your own laptop, although the task you want to do is as simple as changing a CMOS battery. It takes more than confidence, knowledge of the location of the battery in the laptop and having the right tools to perform the task. A right way to start is to know what you want to do and how you want to get into the point of doing the task, in other words, what to disassembly first, second, third and so on.
Unlike a PC, disassembling a laptop is not a matter of loosing all screws and pulling all cases then you can see everything in the box. A laptop is different from the larger personal computer because firstly a keyboard in a laptop is located on top of the machine, secondly opening the bottom cover of the laptop doesn't mean we can see the laptop machine and thirdly, in order to open the bottom cover itself you need to find the unseen screws, which somehow may be located "under" the keyboard.
My first adventure in disassembling my old, secondhand and cheap Compaq Presario 700EA nearly successfully break down the unlucky machine and at one stage I thought if I could not assembly it again, then I would have had to get it binned permanently. I tried to loose all screws that I could see at the bottom cover of the laptop and thought it should be enough. I started to pull the cover but failed to open it and forced it until it nearly cracked.
I thought I needed to disassembly the screen first so that I can open the bottom cover, so I pull out all screws on the screen and disassembly everything. I still could not take the bottom cover off. Then I realises there must be some screws that still hold the bottom cover. These screws might be located under the keyboard, so I tried to pull my keyboard but I don't know how to do it. I decided to take its button off one by one. When I realised the screws were not there (which means I did another mistake), I spent more than one hour to assembly everything back to as before my work started.
Having finished assembling the laptop, I browsed the internet afterward and found the following website, which provides instruction on how to disassembly a COMPAQ laptop:

Apparently, I should not have opened up the bottom cover of my laptop to change a CMOS battery. I just need to take off the LED panel, the keyboard, the optical drive and the plate where the keyboard sits.
In total I just need to loosen about 8 screws, 3 in the bottom of the laptop and 5 under the keyboard. I don't need to touch the screen whatsoever, let alone totally disassembling the screen as I did before I learned from the website. The keyboard itself can be folded as a whole once the LED panel has been taken off. So I don't need to take the buttons off one by as one as I tried to do before.
I was lucky to be able to assembly my computer back without having any major problem when I disassembled it. I broke the button of the conventional modem of my laptop when I pulled it apart, but everything else is fine. Finding the website above has helped me fixed my laptop more efficiently and now the CMOS battery of my old laptop has been replaced with a new one. No more adjusting time and date every time when my Ubuntu start up. The lesson to learn is, make sure you know what you want to do and how you want to do it. Don't forget to learn from others.
