Ok, my stupid laptop won't work at all. I press the power button but nothing happens. No lights come on, not even the little lightning bolt. I took out and put back in the battery and still nothing happened. I looked everywhere to help me but everything sucked. WTF DO I DO?

described a classic "no power, no LEDs" symptom. and are on the right track with the basic reset and adapter checks; the following expands into the next useful diagnostics and safe actions to isolate the fault.

If the adapter appears OK, verify its output with a multimeter (match the voltage on the adapter label). Observe the adapter brick LED (if present) and watch for any faint LED flicker on the laptop or a repeating blink pattern when you gently wiggle the DC plug—those blink counts are diagnostic on many HP models. If the adapter shows correct voltage but the laptop never registers it, the DC jack, cable, or the board input circuitry is the likely culprit.

If comfortable opening the chassis (voids warranty if still covered), power down, unplug and remove the battery first, then try a minimal-power test: remove drives and other peripherals and boot with only the CPU/RAM installed, trying one RAM stick in each slot. Look for physical signs of damage around the power-in area (burn marks, bulging/leaking capacitors). Many Pavilion models use a small, replaceable DC-in/daughterboard; replacing that is often far cheaper than a full motherboard swap.

If none of the above yields a change, the fault is probably internal (fuse/regulator/MOSFET or mainboard). At that point seek a repair shop that can probe motherboard rails and tell whether the DC-in board, a replaceable component, or the mainboard must be replaced. Safety note: do not probe live circuits or attempt solder repairs unless experienced. Posting the adapter model/label voltage, any blink pattern, and whether the laptop ever shows any transient lights will help narrow the diagnosis.

The first thing I'd try is: 1: remove the battery, 2: hold the power button down for 60 seconds 3: replace the battery 4: attempt to boot. if this dosn't work then I wold suspect the battery, if the battery checkes out then is more than likely a hardware issue and will need further work.

Have you check the power adapter? That might be the cause.
