What this fixes
Why people book a dead device diagnostic.
- Nothing at all on the screenNo logo, no backlight, no response to the charger.
- 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 gets warm on the charger and never startsSomething is drawing current. Worth a diagnostic before anything else is tried.
- It died and will not respond to any button combinationCould be the battery, the port or the board. Guessing here is what costs people money.
- It stopped after an updateMore likely software than hardware, and usually the most recoverable outcome.
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 went dead after a drop
Something is disconnected or cracked inside. Usually recoverable, and worth telling us it was dropped.
IfIt went dead after getting wet
This is a liquid damage assessment, not a dead device diagnostic. Do not charge it in the meantime.
IfThe battery is years old
Check that before anything else. A cell that cannot hold voltage under load produces exactly this.
IfYour data is the priority
Tell us before we start. Some routes preserve everything and some do not, and knowing your priority decides which one we try first.
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?
Where Apple supplies a service part for this component, that is what goes in. Where it does not, we fit premium aftermarket and say so. Which of the two you are getting is settled before you agree to anything, and the 360-day warranty does not change between them.
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.
What the €30 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.
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
The price is confirmed to you before anything begins, and it does not move afterwards unless you agree to something else.
The repair is carried out
Carried out here in Drumcondra rather than sent away, by people who do this repair daily.
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.
Power draw on the bench
Before the phone is switched on, because a short does more damage the moment it gets power.
Display and its connector
A phone that is running but dark is a completely different repair from a dead one.
Charge behaviour on a known good supply
Because a failed charger and a failed device look identical from the outside.
Current draw at rest
A board that draws nothing and a board that draws too much are two different faults.
What happens to what is on it?
We are replacing a part, not reading a phone. Your photos, messages and accounts are not something this job touches.
The one place it comes up is testing. A repair is not finished until it has been used, and using a locked device means a passcode. You are welcome to withhold it, and we will tell you which checks that leaves undone rather than quietly skipping them. A passcode you do give us lives on a paper docket that gets shredded, never in a database.
Back it up first if you can. A device that has taken a knock has had its storage shaken whether or not anything looks wrong, and a backup is free insurance against the day that matters.
Will it still survive a splash?
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.

MacBook Air 15-inch (M4) screen questions.
€30, including the part, the fitting, the testing and the 360-day warranty. VAT is included. You get that figure confirmed before anything is opened, and if we cannot repair the phone 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 Air 15-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.
Usually not, which is the good news. Chargers, batteries and software account for most of them.
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.
On older models, yes. On Apple silicon and most recent Intel MacBooks, memory and storage are soldered to the board and cannot be changed. Tell us the model and we will say straight away.
