Electrical Safety

It is of utmost importance to remove the power while disassembling the computer except while measuring voltages. Removing the power not only includes turning off the power switch but also unplugging it from the socket.


Ensure that the power plug should be unplugged to ascertain that there is no power in the computer.  This is required as certain power providers need to provide service to the motherboard even when the power has been switched off.


The following two points should be kept in mind while working with power supplies:
• Refrain from opening it when it is plugged in.
• Even after unplugging,  the capacitors continue to hold, in which case, if the capacitor is touched, it can discharge and give a shock.
