Module 3: Desktop Hardware Troubleshooting and Upgrades

Diagnose power supply unit (PSU) failures using a standalone PSU tester or paperclip test, while assessing ripple and voltage stability.
Swap failed M.2 NVMe drives in systems where BIOS settings must be adjusted for boot priority and PCIe mode.
Troubleshoot no-post conditions by testing motherboards outside the chassis with minimal components (breadboarding).
Upgrade legacy desktops with UEFI-compatible GPUs when existing PCIe slots lack legacy option ROM support.
Replace failed cooling fans in compact form-factor desktops where space constraints limit aftermarket part compatibility.
Validate RAID 0 array integrity after replacing a failed drive in consumer-grade systems without hot-swap capability.
Manage BIOS version compatibility when introducing newer CPUs into older motherboards requiring microcode updates.
Secure internal cabling in densely packed cases to prevent airflow obstruction and accidental disconnection.

Module 4: Peripheral and Input Device Support

Diagnose intermittent USB device disconnects by testing across ports, hubs, and controller types (USB 2.0 vs 3.0).
Replace failed external hard drive enclosures while preserving data by transferring the internal drive to a known-good housing.
Test and recalibrate docking stations that fail to enumerate multiple displays or Ethernet connections after firmware updates.
Replace mechanical switches on enterprise-grade keyboards using soldering equipment and component-level diagnostics.
Validate HID descriptor conflicts when third-party peripherals interfere with built-in laptop input devices.
Configure KVM switch settings to maintain consistent peripheral mapping across multiple hosts with different OS types.
Dispose of peripherals containing sensitive data (e.g., printers with embedded storage) following data sanitization policies.
Source replacement parts for legacy peripherals no longer supported by manufacturers through authorized refurbishers.

Module 5: Mobile Device Hardware Interventions

Replace cracked smartphone screens while preserving digitizer calibration and proximity sensor alignment.
Diagnose water damage indicators and assess whether liquid exposure voids warranty or requires full board replacement.
Reconnect dislodged battery connectors in sealed tablets using non-conductive tools to avoid short circuits.
Reflow or replace power management ICs (PMICs) on logic boards exhibiting charging failures, using hot air rework stations.
Test and replace haptic feedback motors in devices where vibration alerts are unresponsive or erratic.
Manage ESD risks during micro-soldering operations on densely packed mobile logic boards.
Validate IMEI and serial number integrity after board-level repairs to ensure network and warranty validity.
Source OEM versus aftermarket parts for mobile repairs, balancing cost, longevity, and warranty compliance.

Module 6: Data Preservation and Drive Recovery

Image a failing mechanical hard drive using write-blockers and forensic tools before attempting physical repair or replacement.
Use freezer method temporarily to recover data from drives with seized bearings, acknowledging condensation risks.
Recover data from SSDs affected by controller failure using PC-3000 or similar tools in conjunction with NAND mirroring.
Decide whether to engage third-party data recovery labs based on cost, sensitivity, and likelihood of success.
Clone drives using sector-by-sector imaging tools while preserving partition tables and boot sectors.
Handle drives with bad sectors by limiting read retries and adjusting timeout values in cloning software.
Securely wipe drives post-recovery in accordance with organizational data retention and disposal policies.
Document chain of custody for drives containing regulated data during the recovery process.

Module 7: Inventory, Spare Parts, and Depot Logistics

Maintain a categorized spare parts inventory with cross-reference tables linking models to compatible components.
Establish reorder thresholds for high-failure items (e.g., power adapters, batteries) based on historical incident data.
Track part serialization and warranty status for replaced components to support vendor returns and RMAs.
Coordinate with procurement to source end-of-life parts through authorized distributors or OEM channels.
Validate compatibility of third-party components (e.g., RAM, SSDs) against enterprise hardware qualification lists.
Manage regional variations in power supplies and regulatory compliance (e.g., CE, FCC) for global deployments.
Optimize depot shipping logistics by consolidating multiple failed units into single RMA shipments.
Implement barcode or RFID tagging for spare assets to reduce misplacement and improve audit accuracy.

Module 8: Safety, Compliance, and Environmental Controls

Enforce ESD protection protocols using grounded mats, wrist straps, and ionizers in repair workspaces.
Handle and dispose of lithium-ion batteries according to DOT and local hazardous waste regulations.
Comply with regional WEEE directives for recycling electronic waste and maintaining disposal records.
