Discharging capacitor of laptop

Solution 1:

The way to do this is, with the computer shut down, unplug the computer, remove the battery, and hold the power button down for 30 seconds. This is also called a reset, good for correcting certain issues that pop up with laptops. It essentially drains all the stored energy that remains in a laptop after shut down.
