There are two techniques to changing this switch. Technique 1 is faster but carries slight risk of
damaging the front silver case (while bending the case down as shown in step 5) and is only
recommended for technicians who are comfortable running the risk of causing damage.
Technique 2 requires more disassembly and is longer, but is less likely to cause damage to the
silver case. Please read both techniques to see which one is best for your skill level.
