But the laptop wasn't the problem. The silence was. Installer error → check package arch & signature, logs

8) Troubleshooting quick cheatsheet

• Installer error → check package arch & signature, logs.
• Service crash → inspect kernel logs; look for “invalid ELF class” or module load errors.
• Missing feature → confirm kernel module existence; check vendor release notes.
• High CPU I/O → reduce real-time heuristics, add exclusions, schedule scans off-hours.
• Agent not reporting → confirm network rules, proxy settings, and time sync.

1) Why ARM64 matters

• ARM64 (aarch64) is increasingly common in laptops, tablets, servers, and IoT—better power efficiency and performance per watt.
• Security stacks built for x86/x64 can behave differently on ARM64: drivers, kernel modules, and low-level hooks often need architecture-specific builds.
• Ensuring SEP compatibility preserves centralized protection, policy enforcement, and telemetry across mixed-architecture fleets.

Part 5: Common Pitfalls and Troubleshooting the "Hot" Issues

"My Windows ARM64 laptop still runs hot after installing the native client."

Fix: Check for conflicting security products. Windows Defender may still be active. Disable Defender via Group Policy (Admin Templates > Windows Components > Microsoft Defender Antivirus > Turn off Defender). Then, run C:\Program Files\Symantec\Symantec Endpoint Protection\14.3\Bin\ccSvcHst.exe and set CPU affinity to use only high-efficiency cores (via PowerShell). 1) Why ARM64 matters
