A laptop that won't turn on has 8 possible causes, ranging from a completely discharged battery (free fix) to a blown power IC on the motherboard (₹2,999–₹5,999 to fix at chip level). This guide helps you narrow down which one you have before spending money on repair.
Step 1 — Try These First (Free)
- Remove the charger and hold the power button for 30 seconds — discharges residual capacitor charge. Then plug in and try again.
- Check the charging LED — is it on when plugged in? If yes: the laptop is getting power but not booting. If no: the charger or charging port has an issue.
- Try a different power socket — a tripped circuit breaker or dead socket is a common cause people overlook.
- Remove external devices — a faulty USB drive, external HDD or dongle can prevent boot. Remove all external devices and try again.
- Check for a stuck power button — sometimes the physical button is jammed or not making contact. Press it firmly a few times.
8 Causes — From Simplest to Most Serious
1. Completely Dead Battery
Signs: Charging LED is on, but laptop doesn't boot on battery alone. Works only when plugged in.
Fix: Battery replacement. Cost: ₹1,499–₹4,500. Time: same day.
2. Faulty Charger / Adapter
Signs: Charging LED doesn't light up at all. Laptop was working on battery then died.
Confirm: Test with another compatible charger — if it boots, your adapter is dead.
Fix: Charger replacement. Cost: ₹799–₹2,499. Time: same day.
3. Charging Port / DC Jack Fault
Signs: Charger works on another laptop. LED flickers or shows only when cable is held at a specific angle.
Fix: Charging port replacement or soldering. Cost: ₹799–₹2,499. Time: same day.
4. RAM Fault
Signs: Fan spins, power LED comes on, but screen stays black. Sometimes beeping sounds (1 long beep or 3 beeps).
Confirm: Remove one RAM stick if you have 2, try again. Swap slots.
Fix: RAM reseating (free) or RAM replacement. Cost: ₹1,499–₹3,999. Time: same day.
5. Display / Screen Fault (Laptop IS on, screen looks dead)
Signs: Keyboard backlight comes on, you can hear Windows startup sound or fan, but screen is black or very dim.
Confirm: Shine a torch at the screen at an angle — can you faintly see the desktop? If yes: backlight issue, not a no-power fault.
Fix: Screen/backlight replacement. Cost: ₹1,999–₹5,999. Time: same day.
6. BIOS / Firmware Corruption
Signs: Power LED comes on, fan spins briefly, then cuts off. Or the laptop gets stuck at the manufacturer logo on boot.
Fix: BIOS reflash. Cost: ₹1,999–₹3,499. Time: 1–2 days.
7. Power IC / Charging IC Failure
Signs: No charging LED even with known-good charger, battery fully dead. Nothing happens when power button is pressed.
Fix: Chip-level repair — the power management IC is replaced on the motherboard. Cost: ₹2,999–₹5,999. Time: 1–2 days.
8. Motherboard Failure
Signs: None of the above fixes help. Laptop had a sudden shutdown during use, was exposed to liquid, or fell.
Fix: Chip-level motherboard diagnosis and repair. Cost: ₹3,999–₹9,999. Time: 2–4 days.
Note: Authorised centres quote ₹20,000–₹40,000 for board replacement — chip-level repair is the right path first.
