What the Service Includes
The service covers: full diagnostics (temperature checks, artifacts, POST codes, chip signals), cooling system removal, heatspreader detachment, northbridge/GPU reballing or replacement (BGA soldering on IR station or hot air), flux cleaning, new high-quality thermal paste application, contact verification with multimeter & oscilloscope, load testing (FurMark, Prime95, 3DMark), temperature monitoring, graphics/port stability checks (HDMI/VGA), memory. In some cases — chip replacement with BIOS/EC flashing. For complete laptop repairs — all laptop services. Post-repair often requires software installation.
When the Service is Needed
Northbridge/GPU repair is required for:
- artifacts, lines, flickering, colored spots on screen
- black screen after Windows load or in BIOS
- laptop runs only on integrated graphics (discrete not detected)
- chip temperatures >95–105°C even at idle, constant max fan speed
- no output to external monitor via HDMI/VGA
- sudden failure after drop, heavy heat or dust buildup
- typical models: older Lenovo G/IdeaPad, HP Pavilion, Dell Inspiron, Acer Aspire with Intel PM45/GM45, NVIDIA MCP79, GeForce 8xxx/9xxx/Mxx
If thermal paste replacement & cleaning don't help — solder or chip issue. For desktops — all PC services.
Work Stages
- Diagnostics: Visual inspection, graphics/temperature/artifacts testing, faulty chip identification.
- Disassembly: Cooling & heatspreader removal, old paste cleaning.
- Reball / Replacement: BGA resoldering (reball or new/donor chip swap), ultrasonic flux cleaning.
- Reassembly: New thermal paste application, cooling reinstall.
- Testing: Boot, load testing 30–60 min, temperature/stability monitoring.
- Final Check: Ports, memory, Wi-Fi, battery, full functionality verification.
For phones — phone repair.
