When Your Computer Stops Working
A computer that won't turn on is scary. Your work, photos, everything—trapped inside a dead machine. But "won't turn on" isn't always a death sentence. Many power issues are fixable: bad power supplies, failed batteries, corrupted firmware, or loose connections.

Common "Won't Turn On" Problems
Describe what happens when you try to turn it on—this helps us diagnose:
⬛ Nothing At All
Press the power button, nothing happens. No lights, no sounds, completely dead. Usually a power supply, battery, or DC jack issue.
💡 Lights But No Screen
Power light turns on but screen stays black. Could be display, graphics, or boot failure. Try connecting an external monitor.
🔄 Turns Off Immediately
Starts to power on then dies within seconds. Often overheating, power regulation, or short circuit issues.
🔊 Beeping Sounds
Beep codes indicate specific hardware failures. We decode them and identify the failed component.
🌀 Stuck on Logo
Shows Apple/Windows logo then freezes. Usually a software, storage, or firmware issue—not the same as no power.
❓ Random Shutdowns
Works for a while then dies randomly. Overheating, failing power supply, or intermittent hardware failure.
