Hi there, I'm new to the site and have been having a problem with my Presario 2500 laptop (Compaq). When I turn it on it starts up normal and all, I get the windows logo with the loading bar beneath it. As soon as it goes to switch screens to my main screen w/my wallpaper, shortcut, etc. I get no display at all, but still get the welcome music. I don't get it. Any ideas?

Brief expert note summarizing the thread and a focused diagnostic path for the symptom described by (Windows logo and welcome sound, then the display goes black). Earlier replies correctly suggested trying Safe Mode () and a power-reset (); several other posters reported very similar no-display or no-start behaviour (, ). The checks below are aimed at separating a software/driver/Explorer problem from an LCD/inverter/cable or motherboard/graphics failure and at preserving data before any repair.

Quick diagnostics (no disassembly):

  • Shine a bright light at an angle onto the screen while the machine is “on” and the display looks black. A very faint desktop image visible under light points to a failed backlight/inverter rather than an OS crash.
  • Attach an external monitor (use the laptop’s monitor-out/VGA port if present). If the external monitor shows the desktop while the laptop panel stays dark, the fault is almost certainly the internal panel, inverter, or cable.
  • Note whether the BIOS/POST splash appears and whether the Windows logo shows before the blanking. If the machine shows BIOS and the logo but nothing afterward while audio plays, that narrows the problem to the OS/driver/Explorer transition or to firmware/driver activation of the display.
  • If accessible, booting a rescue/live USB or CD provides a clean environment to test video output and to copy important files before deeper repair.

Basic hardware checks (for someone comfortable opening the case): reseat the memory and drive (power removed and battery disconnected, ESD precautions). A loose RAM or drive connector can cause odd boot behaviour. If the internal screen is faulty but an external works, replacement of the inverter or LCD assembly is usually the next step; if no video appears anywhere (not even in BIOS or from rescue media), the likely culprits are the graphics subsystem or motherboard and professional diagnosis/data-recovery is recommended.

Safety note: always remove AC and battery and ground yourself before opening the laptop.

Firstly, does explorer load when you log into safe mode?
If so, try the directions .
If not, repair your windows installation using the directions here (its the last step of the first KB article anyway).

I can't even start up in safe mode. When I start up I get the Compaq screen, then it goes to a screen where I need to chose either 1, or Microsoft Windows Home edition, or press F8 to chose other options. None of these options or configurations of options work...

I also have a Compaq Presario 2500 laptop doing exactly the same thing, so I'd be very interested in replies to this thread.... thanks

Try this option and let me know...
Take out your battery, plug removed and then press the power button of Laptop for almost a minute. Once done, re-install the battery, plug in the power supply and restart the laptop using the power button of the laptop.

All the best..hope this resolves your problem...
