#81146 - How to turn ON/OFF power!! |
How do devices such as mp3 players, cell phones, pda turn on/off power?
Most new devices require the user to hold a button down for a 5seconds to turn off the device and hold the same button down for 2sec to turn ON the device. Are they putting the device into sleep? Are they using a solid state switch? |
