A focused diagnostic note for an HP Pavilion t760a showing a flashing green power LED but no POST. The first replies from , and point toward power-related causes; the checklist below expands those observations into safe, ordered checks that isolate cable/adapter issues, PSU faults, front‑panel failures, and motherboard problems.

  • Confirm form factor: for laptops the DC adapter, jack and battery are common culprits; for desktops the mains lead, rear PSU switch and internal PSU-to-motherboard connections are highest priority.
  • External-power checks: try a different wall outlet and a different mains lead; bypass any surge strip. Verify whether an adapter or PSU indicator LED lights or whether the PSU fan spins when mains is connected.
  • Power-cycle / bleed: with mains disconnected, press and hold the front power button about 10–15 seconds to drain residual charge; reconnect mains and attempt a start.
  • Minimal‑hardware boot: with power removed, reduce the system to minimum components (CPU, one RAM stick, onboard video if available). Reseat RAM, remove expansion cards and drives, then test for POST.
  • PSU validation: if a known-good ATX PSU is available, swap it in to confirm or rule out PSU failure. If no spare PSU is available, voltage checks with a multimeter are the safer diagnostic than opening the PSU—do not open the PSU case (capacitors can hold lethal charge).
  • Front-panel and diagnostics: check the power-switch header on the motherboard and, if appropriate, momentarily short the power pins to rule out a faulty case switch. Record any fan spin, beeps or blink patterns and consult HP service documentation for blink/beep codes.

A steady flash with no fans or beeps most often points to PSU failure or a shorted board; for laptops a failed adapter or DC jack is common. When bench-testing is not possible, professional servicing or HP support is the recommended next step.

It's quite likely the power supply. try plugging it in and leaving it for a while ten to twenty minutes, then try starting it up.


Let us know what happens

You may also want to try powering the laptop off the cord whilst the battery is removed. This will test if the cable is working.
