I tried to reseat the ram, now all I get is the power button continuously blinks along with the 3 lights just below the mousepad..help will be greatly appreciated..

John

This thread points toward a storage/POST issue rather than a pure display fault. and steered the troubleshooting toward the drive and BIOS; below is a compact, practical explanation and a short checklist to reduce the chance of a repeat and to verify drive health.

Why this happens (brief): some laptops will stall early in POST if the boot device or its controller is causing errors. That can leave power LEDs lit while the screen stays black. Common hardware culprits are a loose SATA/power contact, a failing drive electronics board/firmware, or an intermittent cable/backplane connection. Reseating a connector can restore contact temporarily even when the underlying component is marginal.

What to do next (apply after the machine is working or if it fails again):

  • Back up critical files immediately.
  • Confirm the drive is detected in BIOS or with a bootable USB/live OS. If the internal display is unreliable, try an external monitor to separate display vs. POST problems.
  • Run SMART and manufacturer diagnostics (bootable tools or by connecting the drive to another PC via USB-SATA). Look for reallocated sectors, read errors, or pending sector counts.
  • If diagnostics show problems, replace the drive. If the drive tests OK but the fault recurs, inspect the bay, connector, and caddy for bent pins, loose screws, or corrosion; replace the connector/caddy if needed.
  • Consider upgrading to an SSD for better reliability and performance. Keep BIOS and firmware up to date after verifying stability.

Safety and prevention: always power down and remove battery/AC before opening the chassis, ground yourself, and keep recovery media handy. The direction from and the BIOS question from were on target — use them as part of a methodical check if the symptom returns.

Have you disconnected hard drive ? Sometimes hard drive creates such a situation . Try this idea and I hope your problem will be resolved .

can you get in to the BIOS?

I will try the Hard Drive..
No I can't get into the BIOS, because the screen is dark, so I can't see the BIOS..
The start light & the others below the mouse pad quit blinking, & are solid blue as are all the lights at the top, but the screen stays black.
I will remove & re-install the hard drive.

Thanks, Removing & re-installing the HD did the trick..
