The MacBook Pro 16-inch (M4) arrived in 2024, with a 16.2 inch Liquid Retina XDR, mini-LED, nano-texture option display and the M4 Pro or M4 Max chip. It carries MagSafe 3, three Thunderbolt 5, HDMI, SD card and headphone and it unlocks with Touch ID in the power button. There is an aluminium frame. The 16-inch is only made with the Pro and Max chips, so there is no base M4 16-inch. Thunderbolt 5 ports and the Center Stage camera mark it out from the M3.

What this fixes

Why people book a dead device diagnostic.

  • It vibrates or chimes but stays darkThe phone is running. That is a very different and usually cheaper problem than a dead one.
  • It shows the logo and restarts, over and overA boot loop. Software, storage or board, and they are not the same repair.
  • It only works while plugged inAlmost always the battery, and one of the easier outcomes.
  • It got hot and then diedWorth mentioning. Heat before failure narrows down where to look considerably.
  • It vibrates but nothing appearsThe device is running. That points at the display or its connector rather than the power side.
  • It works only with the charger connectedThe battery is finished, and that is the cheapest of the possible causes.
Before you spend anything

Is it definitely a power fault?

A dead phone is the one case where guessing is expensive, because every possible cause has a different price.

IfIt vibrates, chimes or connects to CarPlay but the screen is black
The phone is alive and you cannot see it. That is a display, a connector or a backlight fault, and it is a far better outcome than a dead board.
IfIt works only while plugged into power
That is the battery, and it is the cheapest thing this can be.
IfIt went dead after getting wet
This is a liquid damage assessment, not a dead device diagnostic. Do not charge it in the meantime.
IfIt went in water first
Liquid damage takes priority. Do not charge it and do not keep trying to power it on.
IfThe battery is years old
Check that before anything else. A cell that cannot hold voltage under load produces exactly this.

If you are not sure which of these you have, that is what the free diagnostic is for. It costs nothing and it is the step that stops people paying for the wrong repair.

What parts do we fit?

Two tiers, and you choose knowing which is which: a genuine Apple service part where one is made for this component, or premium aftermarket where none is. The warranty is 360 days on either.

Nobody here will call a part original when it is not. If what fits your laptop is premium aftermarket, you hear that word at the counter rather than reading it on a docket afterwards.

    Genuine, OEM and aftermarket: what the words actually mean

    What the Diagnostic includes

    • A full diagnostic on the bench, free
    • A written answer on what has failed and what it costs
    • No further work until you have approved the price
    • No fee at all if we cannot fix it

    Nothing extra gets done and charged for without you saying yes to it. Where the diagnostic turns up a second fault, the work stops there and you hear the price before it goes any further.

    Diagnostics from €25. A clean-up check is free.

    A collection and return across Dublin can be added when you book. The repair price and the warranty are the same either way.

    How we do it

    From the counter to back in your hand.

    Tell us what it is doing

    Book online in about two minutes, or walk in without an appointment. Describe the symptom rather than the repair, it is more useful to us.

    Diagnostic

    Nothing is opened or ordered until we know what failed. There is no charge for this and no obligation to go ahead afterwards.

    You approve the price

    You get the exact figure before any work starts. Nothing else happens without asking you first.

    The repair is carried out

    Done at our Drumcondra bench by the technicians who do this every day.

    Bench testing

    We test what we replaced and everything that sits beside it, because that is where a rushed repair shows up.

    Back in your hands

    Collected from Drumcondra, or returned to your door if we picked it up. Covered for 360 days.

    Before it goes back

    What we test every time.

    A repair is not finished when the part is fitted. It is finished when the things around it have been checked.

    Display and its connector

    A phone that is running but dark is a completely different repair from a dead one.

    Board inspection

    Under magnification, where the answer is when everything else has been ruled out.

    Charge behaviour on a known good supply

    Because a failed charger and a failed device look identical from the outside.

    Storage integrity

    Where the fault points that way, since it decides whether the data comes back.

    What happens to what is on it?

    This is hardware work. We do not need to go into your photos, messages or accounts to do it, and we do not.

    We do need to switch the device on and use it to test the repair, so we may ask for your passcode. If you would rather not hand it over, tell us and we will show you what we cannot verify without it. Any passcode you give us goes on the paper docket and the docket gets shredded. It is never stored in our system.

    Back the device up before any repair. Not because we expect to lose anything, but because a device that has already been dropped is one whose storage has already been shaken, and a backup costs nothing.

    What about the water resistance?

    After any repair, ours included, work on the assumption that the device is no longer water resistant.

    The rating on the box was measured once, on a sealed unit, in controlled conditions. It was never a promise about the device three years later. Adhesive hardens, seals compress and a single drop can break the seal without leaving a mark you would notice.

    We reseal with fresh adhesive and it does a real job: rain, splashes and a wet counter are all fine. A submerged phone is not, and we would rather say that plainly than let you find out.

    If yours goes near water regularly, say so at the counter and we will tell you what the adhesive covers and what it does not.

    The 360-day warranty

    Every completed repair is covered for 360 days on the part and the workmanship. If the display we fitted fails, or the fitting was at fault, we put it right at no charge.

    What it does not cover is a new accident. A phone dropped again after the repair, fresh physical damage, liquid damage, or a fault in a part we did not touch, all sit outside it. That is the same limit any honest repair warranty has.

    No fix, no fee. The diagnostic is from €25, and if the repair does not happen you pay nothing.

    Three ways to get it to us

    • Walk in to Drumcondra4 Richmond Road, Dublin 3. No appointment. Mon to Sat 10:00 to 18:00, closed Sunday. Most phone screens and batteries done in 15 to 45 minutes while you wait.
    • We collect and returnDoor to door across Dublin, Monday to Friday, usually 2 to 4 working days. The repair takes the same time; the courier is the difference.
    • Send it in yourselfPost it to the shop with a tracked, insured service and a note with your number. We cannot cover a parcel in transit, and that is the honest trade-off for the route existing.

    Same repair price and the same 360-day warranty on all three. The only thing that changes is how the device travels.

    Asked all the time

    MacBook Pro 16-inch (M4) screen questions.

    We quote it after a diagnostic, from €25, because the price depends on what we find. No fix, no fee, so if we cannot repair it you pay nothing.

    Assessed first, then quoted. If the diagnostic turns up something else, or a part has to be ordered, we tell you before you commit rather than after.

    A clean-up check is free. Any other diagnostic on the MacBook Pro 16-inch (M4) is from €25, and you are told the cost before it starts. No additional paid work happens without your approval.

    No. The diagnostic is from €25 and there is no fee if we cannot fix it. You get told what has failed and what it costs before anything happens.

    Usually not, which is the good news. Batteries and charging faults account for most of them, and both are ordinary repairs. The board is what we check when the cheaper answers have been ruled out.

    Often, and tell us that is the priority before we start. Recovering data and repairing a phone are sometimes done in a different order, and choosing wrong can cost you both.

    Batteries fail suddenly more often than people expect, particularly in cold weather and particularly once they are a few years old. It is worth checking before assuming the worst.

    No. It is free, you are told what has failed and what it costs, and there is no fee if we cannot fix it.

    No. If it has looped or failed repeatedly, leave it off. Repeated attempts on a device that is failing under load do not help and occasionally make things worse.

    Often yes, and say that is the priority before we start rather than after.

    Usually same day. Where a fault only appears under load we sometimes have to leave it running, and we say so at the counter rather than leaving you wondering.

    Yes, because dead rarely means dead. The usual causes are a failed battery, a charging port that stopped delivering power, or a board fault after a drop or a spill, and the first two are routine repairs. The diagnostic is from €25, so finding out costs you nothing.

    Whether it draws any current at all, which tells us straight away if this is a battery and port problem or a board problem. From there we work through power rails on the bench. You get a plain answer and a price before anything is replaced.

    Usually yes, and that is a separate job to reviving the device. Even where a board is beyond economic repair we can often recover what is on the storage.

    You pay nothing. No fix, no fee covers the diagnostic and the handling, so the only time you pay is when the device comes back working. If a repair turns out to cost more than the device is worth, we tell you that instead of doing it.

    iMEND is an independent repair service. Brand and model names are used only to describe the devices we repair. We are not affiliated with, endorsed by or an authorised service provider for any manufacturer.

    Why bring it here

    An independent workshop, not a kiosk.

    We are a dedicated repair bench in Dublin 3. That means we take on work authorised channels turn away, and we tell you honestly when something is not worth fixing.

    Diagnosed, not guessed

    Every device is tested before we quote, so you are not paying for a part that was never the problem.

    Parts that last

    Genuine or OEM-grade components chosen for your model. We tell you which is going in before we start.

    Your data stays yours

    Hardware-only repairs. We never read, copy or move anything on your device.

    No fix, no fee

    If we cannot repair it, there is nothing to pay. Diagnostics from €25, no handling charge.

    Bought a phone at imend, Drumcondra, near DCU. What could have been a difficult experience for an untechical minded person like myself was made so easy by the very helpful staff member who ensured my phone was up and running smoothly with everything working well before I left the shop.
