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..

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.
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.
try to turn it off and then remove cables and battery. Press and hold power button for 8 secs to drain the excess power and reset the boot setup. Reinsert cables and battery on it and then turn on the laptop.Check if you still have problem. Otherwise let your pc rest for at least 2hrs .
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.
Please remove any external devices (if connected) to your laptop Remove the power adapter cable Remove the battery Push and hold the power button for 10 seconds, this will remove unwanted charge from the laptop electronics. Then connect the power adapter cable alone and switch the laptop on and check if it is working fine. If not remove the power adapter and connect the battery alone and try if it works fine. If it still does not then we have to remove the other components that are detachable from the laptop like
1. CD / DVD drive 2. Hard drive 3. Memory modules (if you have 2 remove one) 4. PC cards
even after checking with all the above options, if the computer is freezing we can definitely confirm a core hardware issue.
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
The second battery would replace the cd/dvd drive in that slot. Obviously you would lose the ability to play cds/dvds..The drive is easy to remove -just push on the button to the right and then pull out the drive. Hope this helps..Michael
