this is the video tutorial on changing the CMOS battery that worked for me: • Como Trocar a Bateria ... (it’s not in English but you don’t really need to understand what he’s saying)
i used the guitar pick to pry the two frontal clips open (the ones on either side of the faceplate).
another thing you might want to do while you’re inside is remove any lint and dust that may be trapped between the filter of the heatsink (that’s the big copper L) and the fan. just undo the five screws and gently pull it up by its copper neck, then peek where the filter was. this laptop is prone to accumulate a lot of debris in that area, stopping the airflow and causing overheating. it’s also a good idea to use some canned air to clean the filter of any further residue.
