Brief follow-up to the suggestions from , and with a focused, low-cost diagnostic path and realistic repair options.

Try these quick isolation steps first (safe and cheap; power off, remove battery and AC before opening):

  1. Power‑drain and AC check: remove battery, hold power 30 seconds, plug AC only and try power. Try a known-good AC adapter or measure adapter voltage at the jack.
  2. RAM swap: reseat modules and try one stick at a time, in each slot. Faulty RAM or a bad slot will often stop POST quickly.
  3. Minimal boot: remove HDD/optical and any USB devices, then power up — this forces a faster POST and avoids drive/OS hangs.
  4. External vs internal display: with AC connected, toggle the display output (Fn key combo) and reseat the LCD ribbon at the hinge if comfortable; a loose LVDS/eDP cable can give external video but no internal display.
  5. CMOS reset: remove the coin cell for a few minutes (power removed) then reinsert — restores default BIOS settings.
  6. Visual inspection: look for bulging or leaking capacitors, scorched components, or a loose DC jack. Smell for burning. Only inspect with power removed.

If those don’t change anything, the behavior (fan spin briefly then stop, no POST) usually points to motherboard or GPU power/fault. Repair paths: a board swap with a known-good donor, or professional board repair (reflow is a temporary fix; reball/replacement of BGA GPU is more reliable but costlier). Balance repair cost vs replacement for an older laptop.

Notes and cautions: avoid metal tools on powered boards, discharge yourself to prevent ESD, and pull any important drive for data backup before sending the unit to a shop. If you post exact LED/beep patterns and which RAM/test steps you tried, more targeted advice can be provided.

How old is this system? It sounds like a motherboard problem, such as bad capacitors, bad solder joints, etc.

I recall this model to have issues like that. Your choice to google it up and find out what folk did before. If this hit our shop counter the estimate could send the owner away crying.
