Laptop or PC won't turn on — Dublin repair
A machine that shows no signs of life, restarts in a loop or dies halfway through Windows is one of the most common jobs I see. Most of the time it is the charger, the power jack, the battery or a corrupt boot configuration — not a dead computer.
- Price range
- €50 – €140 (diagnostics included; parts quoted separately)
- Turnaround
- Usually same-day or next-day
- Warranty
- 6 months on parts
Signs you have this problem
- No lights, no fan, nothing happens when you press power
- Lights come on but the screen stays black
- Blue screen (BSOD) or a spinning loop before the desktop loads
- Random shutdowns, especially under load
- Charger connector feels loose or only works at an angle
What usually causes it
- Failed charger or a broken DC power jack on the laptop
- Swollen or dead battery no longer holding charge
- Corrupt bootloader, damaged Windows update or failing system drive
- Faulty desktop PSU or loose internal power connectors
- Overheating protection shutting the machine down
What I do
- Full power-path diagnostic — charger, battery, jack and internal power rails
- Charging port and laptop power jack replacement
- Boot repair, bootloader rebuild and Windows / macOS recovery
- Desktop PSU replacement and internal connector checks
- Drive health test, so a dying disk isn't mistaken for a power fault
Common questions
My laptop is completely dead. Is it worth repairing?
Usually yes. A dead-looking laptop is most often a charger, jack or battery issue, which is a fraction of the cost of a new machine. I tell you before any work whether the repair makes financial sense.
Will I lose my files?
No. Startup repairs are done without wiping data wherever possible, and I take a backup first if the drive shows any sign of failing.
