Lenovo Desktop SMPS Replacement — Symptoms We Fix

Common signs your Lenovo desktop needs smps replacement in Narsingi.

Completely Dead

Power button does nothing — no fan spin, no LED, no beep. SMPS most likely stopped providing output voltage.

Cuts Off Randomly

Desktop shuts down without warning during use — SMPS over-current or thermal protection tripping.

Fan Spins But No POST

Power supply fan spins but system never reaches BIOS — one output rail low or absent, starving the board.

Burning / Electrical Smell

Burning smell from the PSU area — capacitor or coil failure inside the power supply unit.

Keeps Restarting

Desktop restarts in a loop before reaching Windows — PSU voltage sag under load causing repeated resets.

Only Powers Briefly

System starts for 2–3 seconds then powers off — SMPS protection circuit detecting a fault and cutting power.

Lenovo Desktop SMPS Replacement Narsingi FAQs

How much does SMPS replacement cost in Narsingi?+

Visit charge ₹149 includes travel and on-site diagnosis. Standard tower SMPS (Pavilion / OptiPlex / IdeaCentre): ₹1,500–2,800. Gaming tower PSU (OMEN 750W / Alienware / ROG): ₹2,500–5,500. We confirm the PSU is the fault before replacing — No Fix No Fee.

What is the SMPS in a desktop and why does it fail?+

The SMPS (Switched-Mode Power Supply) is the metal box inside your desktop tower that converts 220V mains voltage into stable 3.3V, 5V, and 12V for the motherboard, drives, and GPU. It fails from age (capacitors dry), power surges, or overheating. It's the most common cause of a completely dead desktop.

Can you replace the SMPS at my home or office in Narsingi?+

Yes — SMPS replacement is a standard on-site job. Engineer arrives with the correct replacement unit for your Lenovo desktop model, swaps the PSU, and tests the system before leaving. Most jobs done in 1–2 hours at your door in Narsingi.

How do I know if it's the SMPS or motherboard that failed?+

Free diagnosis at your door determines this. If power button does nothing at all → likely SMPS. If fans spin, LEDs light but no POST → more likely motherboard or RAM. If the system cuts off under load → SMPS protection. We use a PSU tester before dismantling to confirm fault location.

What wattage SMPS should I use for my Lenovo desktop?+

Standard Lenovo home towers need 300–400W. Gaming towers with discrete GPUs need 550–750W (OMEN / Alienware high-watt). We bring the correct wattage for your specific model — you don't need to research this yourself. Using an undersized PSU causes repeated shutdowns.

Is a dead SMPS always repairable or must it be replaced?+

Dead SMPSs are almost always replaced rather than repaired — individual component replacement inside the PSU is rarely cost-effective. A new PSU costs ₹1,500–2,800, far less than the time to micro-repair a failed unit. Diagnosis first confirms the PSU is the fault.
