Free diagnosis at your doorstep · Most fixed in 1-3 days
Before you assume the worst — or accept an authorised centre’s ₹15,000+ “motherboard” quote — let us diagnose. About 70% of dead laptops we see have a single chip-level fault that costs ₹4,000–₹8,000 to fix. Your data is recoverable either way. ₹149 visit, No Fix — No Fee.
The pattern of zero-response, partial-response, or one-second-flash tells us where the fault is. Eight scenarios we see weekly.
Charger plugged in, nothing lights up anywhere. Power-section short, EC chip dead, or charger not delivering.
Charger working, laptop not accepting. Charging IC or DC jack failure on the motherboard.
1-2 second flash of power, then black. Voltage regulator failing or short circuit triggering protection.
Brief fan noise, no boot. CPU power-rail issue or BIOS corruption preventing POST completion.
Battery completely dead or charging-circuit cut off. Battery + charging IC test before quoting.
Worked, then stopped after coffee/water. Corrosion on power-section components — act fast.
Surge or under-voltage event killed the charging IC or main MOSFET. Usually chip-level fixable.
Update interrupted or corrupted. EC firmware re-flash, sometimes BIOS chip swap. Recoverable.
When you press the power button, a precisely choreographed sequence has to complete in roughly 200 milliseconds. The button signals the embedded controller (EC) — a tiny dedicated chip that’s always alive when the laptop has any power source. The EC checks for valid input voltage, then commands the main power-section MOSFETs to enable a chain of voltage rails: 19V down to 5V, 5V down to 3.3V, 3.3V down to 1.8V, 1.05V, and so on for the CPU, RAM, GPU, and display. Each rail must come up in the correct order. If any rail fails to reach its target voltage within a fixed window, the EC aborts the boot and the laptop appears dead.
This is why “dead” rarely means “dead motherboard.” Almost every no-power case traces to a single component in this sequence: the charging IC (won’t accept input from the charger), the EC chip (firmware corrupted or chip damaged), a MOSFET in the power section (shorted, killing one of the voltage rails), or a capacitor on a critical rail (failed open or short). The rest of the motherboard — CPU, RAM, GPU, storage controller — is typically perfectly fine. Replacing the single faulty component restores the boot sequence and the laptop comes back to life.
The diagnosis itself is methodical. We first verify your charger output with a multimeter (sometimes the customer has been told the laptop is dead when actually the charger is). Then we apply known-good power and probe the main voltage rails on the motherboard with a meter or thermal camera, looking for the first rail that’s missing or shorted. A shorted rail glows warm under thermal imaging within seconds — that’s usually the failed component. A missing rail traces back through the power-on sequence to the chip that should have enabled it. Either way, we identify the faulty component, not just the symptom.
Liquid damage and surge damage are the two cases that most reward this discipline. After a coffee spill, corrosion typically affects only the components nearest the entry point — usually the keyboard’s membrane and the underlying power-section ICs. After a power surge, the charging IC and the main input MOSFET are the usual casualties. In both cases, ultrasonic cleaning + targeted component replacement restores the board. We’ve recovered laptops that authorised centres declared total losses, often for under ₹8,000.
Your data is independent of the power circuitry. Even on a board we can’t recover, we remove the storage drive, place it in a USB enclosure, and hand you back your files within 24 hours. The ₹149 diagnosis includes this. You won’t lose your work, regardless of whether the laptop itself is salvageable.
Same-day diagnosis. Most chip-level repairs complete in 1–3 days. Free pickup & drop across Hyderabad.
60-90 min at your address. Charger test, voltage-rail probe, thermal scan. We find the faulty component.
Charger / DC jack / chip-level / board swap — we tell you which, with prices, in writing.
Charger or DC jack done same-visit. Chip-level board work goes to our Secunderabad workshop (1-3 days).

The right price depends on what’s actually faulty. Below are typical ranges across the eight common causes — final figure fixed at the diagnosis stage.
₹149 diagnosis covers travel + full power-rail testing. No Fix — No Fee on the repair: if we attempt and can’t fix, you pay only ₹149.
What customers ask before booking diagnosis for a dead laptop in Hyderabad.
A laptop that won't turn on can fail at the charger, board, button, or display. These are the related repairs we run during diagnosis.
First test — is the brick supplying voltage? Genuine OEM charger replacement if the brick is dead.
Charger good but laptop dead? DC jack might be starving the SIO chip of standby voltage.
Power button itself might be the fault. Button + SIO chip pathway tested before deeper repair.
If charger + jack + button all test OK, motherboard chip-level repair (PMIC, EC, SIO) is needed.
Some "not powering on" cases are actually no-display — fans spin, screen blank. Combined diagnosis.
A corrupted BIOS / EFI prevents POST. BIOS reflash recovers most boards without any board-level work.
