Study Notes
Smart Card Readers
- Two types: Contact readers require physical insertion of the card; contactless readers utilize radio frequency for communication.
SODIMM Memory
- Laptops use Small Outline Dual In-line Memory Modules (SODIMM), unlike desktops which use DIMM.
- SODIMMs are classified by DDR version; compatibility varies by laptop model.
- RAM is accessed via slots located under the laptop's cover, sometimes necessitating removal of the keyboard.
Laptop Hardware Replacement
- Customer-replaceable units (CRUs) include components like batteries and RAM; field-replaceable units (FRUs) include motherboards and displays.
- Common repairs include diagnostics, data recovery, keyboard and fan replacements, and internal cleaning.
Battery Replacement Indicators
- Signs for battery replacement: failure to hold charge, overheating, or leakage.
- Replacement batteries must meet or exceed original specifications regarding form factor, voltage, and power ratings.
Internal Storage and Optical Drives
- Laptop drives are smaller than desktops, typically 1.8 in. or 2.5 in. wide.
- Most storage devices are CRUs and accessed through removable covers or by removing the keyboard.
Cell Phone Parts
- Field-replaceable parts in cell phones include memory, SIM cards, and batteries.
- SIM cards authenticate devices and store user data; Secure Digital (SD) cards expand memory.
Wired Connectivity for Mobile Devices
- Mini-USB, USB-C, micro-USB, and Lightning cables facilitate charging and data transfer across devices.
- USB-C allows connection in either direction.
Wireless Communication Methods
- Wireless options include Wi-Fi, NFC for short-range communication, IR for remote control, and Bluetooth for short-distance data exchange.
- Smartphones can share internet connections through tethering.
Basic Troubleshooting Steps for Laptops and Mobile Devices
- Problem-solving sequence: Identify the issue, theorize causes, test theories, enact resolutions, verify functionality, document findings.
- For laptops: look for issues with battery charge, cable connections, or RAM; for mobile devices, consider battery function and dirt in ports.
Key Terms and Commands
- New terms include smartwatch, tablet, smartphone, fitness tracker, Bluetooth, SIM card, SD card, and various generations of cellular technology (1G to 5G).
- Important commands include application commands for email processing like SMTP, POP3, and IMAP.
Summary of Essential Features
- Understanding the features, configurations, maintenance, and troubleshooting methods of laptops and mobile devices is crucial for effective device management.
