Start with these three steps
Rule out recent damage
If liquid, crushing, overheating or battery damage preceded the failure, leave it off and use the relevant damage guide.
Check the power path once
For an undamaged laptop, inspect the charger and cable, try a working outlet and use a known compatible power adapter if available.
Gather the recovery essentials
Locate the model details, login information and existing backups. Record the last successful use and any interrupted update.
Decide whether it is really a no-power case
Note any image, startup sound, keyboard lighting or response from an attached display. A question-mark folder or other startup symbol means the computer has powered on. A black built-in display can still be a screen or startup problem, so describe what you actually observe.
Avoid repeatedly opening, closing and pressing buttons while waiting for a change. A concise record such as “charger connected, no image, no response after one attempt” helps more than a guess that the SSD is dead. Keep any error message or photograph for assessment.

Make limited checks on an undamaged MacBook
Apple’s no-power procedure includes disconnecting accessories and holding the power button for about ten seconds, then pressing it normally. On a model with Touch ID, that button is also the power button. Use the official instructions for the particular MacBook and stop if the symptom persists.
A hub, external disk or damaged cable can complicate an observation, so make a simple test with unnecessary accessories removed. This limited check is not advice to keep cycling power on a wet or unstable machine. If it starts, make a copy of essential files before further investigation.

Understand the firmware decision before proceeding
For certain Apple silicon and T2 firmware failures, Apple provides a revive procedure using another Mac. Revive is designed to preserve the affected Mac’s contents. Restore is a separate operation that erases it. The fact that both appear in the same support article does not make them interchangeable.
Ask a technician to identify which operation they propose and why. A failed revive does not make an erase acceptable when the only copy of your data is still required. Pause at that decision and consider the remaining hardware and backup options.

Keep working from an independent source
While the laptop is being assessed, inspect existing Time Machine backups or cloud copies from another computer. Create a list of what those sources contain and what is missing. An older backup may be enough to resume most work while the latest local files remain unresolved.
Before authorising service, ask whether a proposed part replacement affects the original storage. Give the repairer the data priority in writing. If a working Mac is urgently needed, restoring a backup to another machine can separate that deadline from the decision about the inaccessible original.

A realistic view of recovery
- A no-power symptom alone cannot establish whether recovery is possible or which component failed.
- Revive is not a general cure for electrical damage; firmware restore erases the Mac.
Your questions, answered
Will a new charger recover my files?
Should I keep attempting to boot it?
Can I connect it to another Mac while it is dead?
Need help with the original MacBook?
Describe the model, what happened and which data matters. Data Recovery Lab NZ is an external specialist; ask it to confirm the assessment route for your exact device.
