My MacBook Pro abruptly shut down by itself while I was working. Brought it to Machine's service centre at NorthPoint and was quoted an exorbitant price for the motherboard. Even the salesperson attending to me personally recommended me to get a new laptop instead since for value its better worth. I knew I had to get second opinions and I recalled my wife just had her laptop fixed by Dotronix earlier this year. I got Arsh's contact from my wife and he was very accommodating after knowing my situation. He told me not to worry, let him check out the MacBook to understand the severity of the situation before he recommends what to do. After a day of checking my MacBook he quoted me a fair price not to change the motherboard but to fix the root of the problem. However after getting back my MacBook there was still issue with it, and again without qualms Arsh took back the MacBook to further investigate it. Long story short, I'm now dropping this review on my "spanking new" macbook thanks to Dotronix, Arsh and his team of specialists. Highly recommended for those who needs to get their devices fixed with a fair price, along with a great customer service. Businesses like Dotronix should prosper with longevity to ensure the mass public has a good source of alternatives for their faulty devices. One more thing I have to add that I was impressed. When the MacBook was brought to Machine's service centre, the MacBook's skin (bottom) had to be cut open for the technician to review the problem. I was distraught to hear but had to comply for obvious reasons. However after sending the MacBook to Dotronix, my bottom skin was replaced with an exact design as my original skin. I know it's replaced as there was a cutout after leaving Machine's centre. For this, kudos to the team1

Dotronix helps to resolve my Lenovo AIO motherboard issue at reasonable cost in 2 days. The staff is able to troubleshoot my AIO and solve the issue in very short time. Highly recommended

What's going on

When a MacBook shows no sign of life, it's tempting to assume the worst. In our experience, a good number of these cases turn out to be a drained battery that won't hold enough charge to boot, a faulty charging cable or adapter, or a display that's actually working but just not lighting up. We test power delivery, battery health and display separately before concluding it's a logic board issue.

Common signs to look out for

  • Completely black screen with no backlight
  • No chime, no fan spin, nothing at all
  • Charging light doesn't turn on when plugged in
  • Screen briefly flashes then goes dark
  • Random shutdowns before failing to turn on again

What usually causes it

  • A fully drained or failed battery
  • A faulty charging cable, adapter or port
  • A display or backlight fault, not a power issue at all
  • A logic board fault, often after liquid exposure

How we diagnose this

01

Power delivery test

We check the charging port, cable and adapter output before assuming an internal fault.

02

Battery health check

We confirm whether the battery is holding charge and able to power a boot cycle.

03

Display isolation test

An external monitor test rules out a display-only fault before we open the unit.

04

Board-level diagnostic

A logic board fault is only diagnosed once every simpler cause has been ruled out.

Common questions

MacBook no power FAQs

Not necessarily. A good number of no-power cases turn out to be a drained battery, a faulty charging cable, or a display fault that's not lighting up — we test each of these separately before concluding it's a logic board issue.
Diagnosis is free. If the fault turns out to be the battery or a cable, that's a cheaper fix than a board repair — final cost confirmed once we've identified the actual cause.
Typically 1 to 3 days for battery or cable-level faults. If it turns out to be a logic board issue, that moves to our chip-level repair timeline of 3 to 7 days.
Simpler faults in this category (a loose connection, a straightforward part swap) are often same-day. The 1–3 days window covers cases where the fault escalates to chip-level board work, which needs micro-soldering diagnostics rather than a quick parts swap. We tell you which category yours falls into right after diagnosis, not at pickup.
No — protecting your data is treated as seriously as the hardware fix itself. Where a repair could plausibly affect stored data, we back up what's accessible before starting work, and we never wipe or reformat a drive without your explicit go-ahead. If your MacBook won't boot at all, ask us about data recovery before assuming anything is lost.
Every repair carries our Standard Component Warranty, terms and conditions applying to labour and the fix itself. If a replacement part carries its own separate manufacturer or supplier warranty — batteries and SSDs typically do — that can extend further depending on the specific part, and we tell you exactly what applies to your repair before any work begins.
No. Basic live-agent assessment is always free at Dotronix, whether you approve the repair afterward or not. You only pay if you say yes to the quote we send you.
Both work, shaped to each hub. Book ahead with Our Live Agent for a guided workshop visit in Kepong, or visit our Kuchai Lama branch — call/WhatsApp first to confirm availability. Either way you get the same diagnosis and pricing.
No. We follow a strict zero-data-touch protocol on every board-level repair — your storage drive is never wiped, reformatted, or accessed unless you specifically request data recovery. If your device won't boot and you need files off it, that's handled as a separate, dedicated data recovery step, not folded into the board repair.
