- Reported configuration
- Intel Core i7-1185G7, 32GB RAM, 15.6-inch display, 2.1 kg device. Storage is not specified in the report.
- System boundary
- Manufacturer's original lifecycle per unit, including components and packaging, distribution from China to the USA, five years of use and end-of-life treatment.
- Use scenario / region
- Assembly in China; distribution, use and end-of-life scenario in the USA.
- Use period in the report
- Five years in the manufacturer's original use scenario. This is not a prediction of the unit's remaining second life.

Values retain the source’s units and rounding. A “less than” value is not zero; percentages are not converted into apparently exact kilograms.
Uncertainty and limitations
The manufacturer identifies usage, disposal, time, technology and geography as uncertainty sources. No numerical uncertainty interval is provided.
Before using this result for refurbishment or ITAD
- Match the published processor and memory; the report does not cover every SKU with the same family name.
- Use local electricity and an evidenced remaining service period for a European second life. Keep the original source scenario separate from that calculation.
