Study Notes
Electrical safety
- Exchanging AC adapters can cause damage to both the adapter and the laptop.
- Some printer parts, such as power supplies, can contain high voltage.
- Ensure to follow electrical safety guidelines to prevent fires, injuries, and fatalities.
Electrostatic Discharge (ESD)
- ESD occurs when an electric charge builds up on a surface and comes into contact with a differently charged surface.
- ESD can cause damage to computer equipment if not discharged properly.
- To prevent ESD damage:
- Keep components in antistatic bags before installation.
- Use grounded mats on workbenches and in work areas.
- Use antistatic wrist straps when working inside computers.
Power Supplies
- Convert AC power into lower voltage DC power required by internal components.
- Form factors include:
- AT – original power supply for legacy systems
- ATX – updated version of AT
- ATX12V – most common power supply currently
Connectors
- Power supply includes various connectors for internal components such as the motherboard and disk drives.
- Examples include:
- 20-pin or 24-pin slotted connector
- SATA keyed connector
- Molex keyed connector
- Berg keyed connector
- 4-pin to 8-pin auxiliary power connector
- 6/8-pin PCIe power connector
Power Supply Voltage
- Connectors provide different voltages.
- Common voltages are 3.3 volts, 5 volts, and 12 volts.
- 3.3 volt and 5 volt supplies are used by digital circuits.
- 12 volt supply powers motors in disk drives and fans.
- Power supplies can be single rail, dual rail, or multi rail.
- A rail is the printed circuit board (PCB) inside the power supply where external cables are connected.
- Computers can tolerate slight fluctuations in power, but significant deviations can cause the power supply to fail.
Motherboards
- Backbone of the computer.
- Printed circuit board (PCB) containing buses (electrical pathways) that connect electronic components.
- Components can be soldered directly or added using sockets, expansion slots, and ports.
Motherboard Components
- Major components include:
- Central Processing Unit (CPU)
- Random Access Memory (RAM)
- Expansion slots
- Chipset
- Basic input/output system (BIOS) chip and Unified Extensible Firmware Interface (UEFI) chip
- SATA connectors
- Internal USB connector
