Board repair vs board replacement: the honest comparison
When a laptop's logic board fails, there are usually three routes: repair the original board, replace it with another board, or write the machine off. Most quotes only mention the last two, because most shops cannot do the first. Here is the comparison with the trade-offs stated plainly, because shops deserve to quote their customers with the full picture.
The comparison
| Board repair | Board replacement | Write-off | |
|---|---|---|---|
| What happens | Failed components on the original board are replaced and tested | The original board is swapped for another one | Machine retired, parts or data handled separately |
| Modern Macs | The only real route. Major components are paired to the board, so a "swap" means pairing problems or lost pairings | Often not a clean swap; pairing and serialisation get in the way | Common outcome without board capability |
| Windows laptops | Component-level work on the fault | Possible if a donor board exists. Condition unknown until fitted | When repair and donor both lose |
| Data | Original board returns, original storage keeps its relationships | A donor board can complicate encrypted storage (BitLocker/FileVault react to hardware changes) | Becomes its own recovery question |
| Warranty | 12 months on the repair, at this bench | Typically 90 days on used parts, if anything | n/a |
| Cost | Fixed at £120 + VAT here | Depends entirely on donor supply, often more than repair | Replacement machine minus data |
When replacement actually makes sense
We are not going to pretend replacement never wins. It can be the right call when the board is genuinely beyond component repair (delamination, unrecoverable corrosion, dead silicon with no donor part), when a matched used board is cheap and plentiful, or when the machine's value makes even a fixed £120 question the economics. What replacement should not be is the default because the shop lacks board capability: that is a limitation of the bench, not of the machine, and it is exactly the distinction this service exists to remove from your quotes.
How we keep it honest
Diagnosis first (£35 + VAT, waived when the repair goes ahead) establishes what actually failed and what repair costs. If the fault is bigger than the fixed £120 + VAT repair covers, a revised quote lands on your portal (with photos) before any paid work. And if the honest answer is that this board should be replaced or the machine retired, the diagnosis says that too, evidence attached. You never get a "repaired" board back that we would not put our 12-month warranty on.
Repair-vs-replace questions
Is board repair more reliable than a used replacement board?
Repair keeps the original board and its paired components, with a 12-month warranty on the work. A used board brings unknown history, pairing complications on modern Macs, and typically a 90-day warranty at best.
When is replacement the better answer?
When the board is genuinely beyond component repair (delamination, unrecoverable corrosion, dead silicon with no part), when a matched donor is cheap and plentiful, or when the machine's value settles it. The diagnosis says so honestly, with photos.
What does board repair cost here?
£120 + VAT fixed, including post both ways and a 12-month warranty, or £180 + VAT in the priority slot. Diagnosis is £35 + VAT and is waived when the repair goes ahead.
