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..

You need to clear the cmos. This is accomplished by removing the cmos battery for 5-10 minutes.
1. Remove the battery
2. Remove the keyboard
3. Remove the LED switch cover
4. Remove the cmos battery cable from the motherboard
5. slide the battery out of the brack
Reverse the step after 10 minutes and the bios should be reset. On first boot you are going to need to reset your clock, settings etc.
no need. just remove the cmos battery and the power cable on the tower, then hold the power botton for 15 seconds and then wait for 2 minutes before you plug the battery and the power cable back in, it should reset the bios and the pw should be remove
If you forgot your bios password, remove the battery, unplug it, open it up, pull out the cmos battery, and hold the power button for 10 seconds to drain any residual charge. Boot without the CMOS battery; the password should be disabled at this point.
Let's see what we can do with this one. It seems you are saying the laptop hangs while trying to boot, and seems not to get that far, that is to the boot stage. Shut the computer off, and remove the power wire and battery...OK... remove any cards, and remove all memory sticks. Now plug the computer in and turn on the power.. see what it says, if anything. The correct message should be something about no memory installed. If that message appears, then you can suspect some problem may be with the memory. If you have more than one memory stick, put one in at a time and check to see what the computer does. There are programs you can download and put on a cd or floppy disk to test your memory sticks. These are free for the downloading. There are diagnostic free programs to test the rest of the computer, with self-booting programs to put on a cd. These can test your computer. If all fails, then you may have a bios problem. Reset the bios by shorting the jumper (on a laptop, this may be harder to get to) on the bios. This will reset the bios to default. See what it does... if still same problem, then repair is in order or sell as parts...part out, what ever.
Remove the battery and to the power cord. Remove the two screws that secure the keyboard. After removing the keyboard, remove the battery “RTC” to stop providing energy to epprom BIOS. After the upgrade or downgrade, or any repair, leave the Laptop for 5 minutes, without any source of energy. Then connect only the power cord without battery and without the battery “RTC” of the Bios.then turn on the pc without the battery and press f10 change the admin password put the battery of the laptop again not the rtc battery then save changes and exit, reeboot with the win xp disk inside , change boot order and done i garantied it work install xp and then connect the rtc battery done. jajaja easy
