Question about HP NC4010 Notebook
When laptop hanged between some task, i removed the battery to reset, but i forgot to remove the power cable before that. any way it was working fine after that. after two three restart, it suddenly stopped to boot.
it just blinks orange/amber LED 9 times when i press power button when on AC or battery. there is no beep, no fan, no display, no green power LED.
i have tried pressing power button for 1 minute after removing both power sources, and reseating RAM modules, resetting bios etc..
i have no idea what is causing this. any help will be greatly appreciated..

Tips for a great answer:
Try this Method:
One of the most common methods to reset the BIOS password is to remove or discharge the battery on the computer's motherboard. If the power to the battery is lost or drained, the BIOS configuration will be reset to the factory state with no password. System settings made to the BIOS will also be lost.
Step 1 - Turn off the computer and ensure it has no external power (ie unplug the power cable. If it has a battery, remove it).
Step 2 - Open the computer's case or box.
Step 3 - Locate the computer's motherboard and look for the white silver button battery on the motherboard.
Step 4 - If the battery is not soldered to the motherboard, remove it carefully and wait for approximately 30 seconds.
Step 5 - Put the computer case back together and boot the computer.
Step 6 - If the "CMOS Checksum Error-Defaults Loaded" error message is displayed, the BIOS password has been reset.
In the event the CMOS battery is soldered to the computer's motherboard, you will want to seek a different method to reset the BIOS password on the computer.
