== I can't turn on the computer, it doesn't wake up ==
=== 1. ''Possible reason: Power supply failure'' ===
=== Solution - Check power supply (PSU) ===
*Make sure the DC cable is not damaged and connected properly to the machine.
*Make sure the AC cord is properly plugged to both sides (Wall mounted well plugged).
*Trying an alternative adapter could eliminate bad PSU.
=== 2. ''Possible reason: Memory failure'' ===
=== Solution - Check memory (RAM) ===
*Verify RAM module is seated firmly in its socket.
*Try to eliminate faulty memory sticks by swapping it with one another.
=== 3. ''Possible reason: Peripherals failure'' ===
=== Solution - Check Peripherals (HDD/SSD/USB)===
*Unplug peripherals and try to power up with bare minimum, that includes HDD/SSD/USB devices.
*Verify power up without storage. Sometimes damaged drives may cause the overall system to malfunction.
