: If the repair estimate (parts + labor) exceeds 50% of the cost of a new comparable laptop , buy new.
: If you have a high-spec gaming or workstation laptop that is only 1–2 years old , the $400–$600 repair may be cheaper than a $1,500+ replacement.
: Instead of a full board swap, find a specialist who performs soldering/micro-repairs (e.g., replacing a fried capacitor). This can often fix a "dead" board for under $300 .
