just as my hp was about to go into hibernate mode the other night (it was closed), all the lights came on and it made 3 loud beeps. now when i try to start it up all the lights come on and it makes the three loud beeps but the screen wont turn on and the only way to turn it off is to remove the battery.

A few focused diagnostics to narrow this down for — ’s pointer to memory faults is a useful lead, and ’s note about HP batch/repair programs is worth checking if warranty still applies. The symptom set (three beeps, lights on, totally dark screen, only powered off by battery removal) can come from either a POST failure or a display/backlight fault. The suggestions below help isolate which.

Try these checks in order:

  • Connect an external monitor (VGA/TV out). If the external shows BIOS/Windows, the laptop’s LCD assembly, inverter or LVDS cable is the likely problem. If the external is also blank, the failure is occurring before video output (motherboard, GPU or POST).
  • Do a flashlight test on the LCD: shine a bright light at an angle while the system is "on". A very faint desktop/BIOS image visible under light means the backlight/inverter is dead while the panel is still receiving the signal.
  • Do a power drain: remove battery and AC, hold the power button ~15–30 seconds to discharge, reconnect AC only and try booting. Note any HDD spin, fan action, LED blink patterns or changes in beep behaviour.
  • Record the exact beep/LED sequence and any hard-drive/fan activity; those details are useful if contacting support or a technician.

If the external monitor works, plan on replacing the screen/ inverter/ cable or having a shop diagnose those connectors. If nothing appears on an external display after the power-drain, the fault is likely board-level (memory, GPU, or motherboard). For dv6000-class machines, that can require motherboard replacement or professional board rework; reflow fixes exist but are often temporary.

Cautions: avoid forcing connectors, observe ESD precautions, and consider warranty status before opening the case. If unsure, supply the recorded beep/LED pattern and serial/model to HP or a reputable repair shop for a faster, accurate quote.

That refers to your system memory. Reseat them several times into their slots. Or test a stick in different slots but it is better to clean its gold contacts first with a pencil eraser before testing it in your system.

Have you checked if your lappy falls in HPs faulty batch? You can check on their website. Obviously they have sold lots of faulty Pavillions. If your model and serial number falls in that batch you are supposed to get a free repair. (Just pray that they dont notice that "the unit has been opened"(if it was) or your extra year of warranty is void).

I have sent mine to HP only to hear that I must pay for repair , despite the fact that they sold me a screwed product!

Here is HPs pavillion link.

Good luck to fellow HP victim.
