Laptop turns off after loading bar during booting process

Found this issue on my 17” 2011 MacBook Pro:
# Press power button, no response, and nothing happens.
# Press shift + control + option together, laptop turns on, can see Apple logo and loading bar, but no Apple chime sound.
# Laptop turns off right before loading bar completes(about 3 to 4 seconds).
# Disconnect the battery, get the power adaptor connected, and repeat #1. #2 and #3 above, same symptom.
What could be wrong, GPU failed on logic bard or something else?
Many thanks,
