i double check couple times already. all those cycle water testing stickers are all white,not red. and don't see any red point and corrosion as well. and yes, it does power on from the battery.

it doesn't spin all the time, but when the test goes like 60% , it spins full speed then slow down later on. don't see any liquid damage,checked couple times already.

sorry about the confusion,thought you said if it was installed

I meant the rom was there and never touched. looks very fine to me

yes of course, the machine can power on ,posts without problems,you can hear chime, see logo, then loading and stuck there.
