I try the bad laptop hard drive, dvd burner, screen, battery in the good laptop and they work fine. i took his heat sink and fan in the bad laptop and the light came on for about 5 sec and then turns off. I have no idea what to try next if u have any idea please post and let me know. it does not show a light went plug in to show its getting power for the cord. but i try both cords. thanks for any help u can give me

Short version: because you already swapped the battery, HDD, DVD and power adapters into a known-good Inspiron 2200 and those parts worked there, the fault is almost certainly on the bad machine’s DC-in/power circuitry or motherboard. The power LED coming on for a few seconds after the heatsink was removed means the board can briefly start then is immediately shutting down — that behavior usually points to a short or a protection/regulator failure on the mainboard rather than a simple adapter or battery problem.

Recommended next checks (do these with the battery removed, AC unplugged, and ESD precautions):

  1. Verify the AC adapter with a multimeter (center pin to outer barrel). If the adapter reads the correct voltage but the laptop still shows nothing, focus on the laptop.
  2. Do a careful visual inspection around the DC jack and power section: look for cracked solder joints, burnt components, or bulging capacitors. Check for missing or loose jack mounting screws or standoffs that could be shorting the board.
  3. Try a minimal-power attempt: remove HDD, optical, wireless card and extra RAM, leave only what is necessary to POST (one RAM stick), plug AC in (no battery) and try power. Do not run the CPU without the heatsink for more than a few seconds.
  4. If the LED comes on briefly then dies, the board is likely detecting a short or an overcurrent and shutting down. If you can, measure voltage rails on the board or use a bench supply with current limiting. If you are not comfortable, stop and get a board-level repair technician to avoid further damage.

Options and cautions: a faulty DC jack, blown SMD fuse, or failed regulator can often be repaired for less than a full board replacement, but for a very old Inspiron 2200 the board cost vs. replacement laptop value should be weighed. Since already ruled out external parts and and covered reset/tap ideas, focus on the DC-in area and a shorted/protecting component — have a repair shop do the power-rail measurements or replace the jack/fuse if you want to pursue repair.

its possible you might have a static build up. to discharge the static you have to look on the bottom of ur laptop and see if their is a pinhole reset button, if yes you need to pull out ur battery and unplug you laptop then hold the reset button for 10 seconds. afterwards you may reinstall the battery and the power supply. i hope you laptop has a reset pinhole...

Just a quick thing that worked for mine surprisingly ahah a :) . Turn it on its screen while closed and give it a hit ( not tO hard ) it seems to work . It must shock it somehow :))
