5. Repair & component-level troubleshooting

• Visual inspection: Use magnification to find burnt components, cracked capacitors, lifted traces, or corrosion from liquid damage.
• Power rail checks: Identify test points for major rails (VCC, VCCIO, VTT, 1.8V, 3.3V, 5V). Validate presence and ripple under load.
• Short detection: Use current-limited bench supply to power board and locate shorted components by temperature rise or current draw.
• BIOS chip recovery: If corrupt BIOS, reflash via SPI programmer (CH341A) by desoldering or using SOIC clip; ensure you have the correct BIOS image for the exact board SKU/revision.
• Reballing/Reflow: BGA reflow can sometimes revive soldered CPU/GPU but is a temporary fix; reballing by a professional may be required for permanent repair.
• Component replacement: MOSFETs, MOS drivers, capacitors, and inductors are replaceable with careful soldering; replace with parts of equal footprint, rating, and spec.

2. BIOS / Firmware

• BIOS type: Phoenix/Award/AMI UEFI variants depending on OEM firmware releases for the specific laptop model.
• Common features:
  • Boot order configuration (HDD, optical, USB, network).
  • SATA mode: AHCI/IDE options (modern boards default to AHCI).
  • CPU features: Intel SpeedStep, virtualization (VT-x) enable/disable.
  • Memory remapping and event logging.
  • Power management: ACPI settings, wake-on-LAN (if supported).
• Updating: Firmware updates must match the exact laptop model and board revision — using a mismatched BIOS can brick the system. Use manufacturer-provided BIOS utility or a recovery method with a USB BIOS flash stick if supported.
