With an extensive use of the notebook, some times notebook would store some static charges which indeed will stop the notebook from powering up or charging the battery. The procedure to remove this static charges from the notebook is known as power drain. Performing a power drain procedure will not effect any personal data or delete any pictures from the hard drive on your notebook.
I recommend you use Power Drain procedure by following these steps:
1. Disconnect the AC Adapter. 2. Remove the Battery. 3. Hold the Power button down for 30 seconds to 1 minute. 4. Reconnect the AC adapter. 5. Turn on the Notebook power.
You could have a faulty motherboard or RAM.
First remove the main battery and boot up the laptop without the main battery connected, if it boots up insert the battery, no need to power down. If that doesn't work, switch off/disconnect the adapter and insert the battery, then reseat the RAM modules and boot up.
If nothing works then you have a piece of junk. You can salvage the hard disk and put it into an USB hard drive adapter case and use it as an external USB hard drive.
Sound's like you've had a hsrd drive crash. The message 32768 kb ok is a memory test, this indicates that something went wrong with the operating system the last time it was shut down. It should, after the memory test, either correct the system problem or give an error code. Since it does nothing, this indicates that the hard drive has failed and, unfortunately, needs to be replaced.
option f2, go into bios setup and see if the hard drive is listed or detected. Auto detect hard drive save and exit. System will reboot if the same error occurs then the hard drive master boot record is probably corrupt or the hard drive has totally failed.
it's possibly a hardware problem but you should make sure it isn't a software problem by putting in your system restore cd and restoring the DLL that you deleted, it could be an important system file. If it is a hardware problem, the first thing to try is taking out your memory and sticking it back in place, make sure it's clean and put it in there tight.
