Hi i have a MacBook Pro (13-inch, Early 2011),

when i try to switch it on

1: the sleep light blinks once
2: the cpu fan starts and stops in 5 seconds
3: no screen
4: no boot up
5: no startup chime

when i connect it to the charger

1: the sleep light blinks after small intervals
2: the cpu fan starts and stops in 5 seconds and at regular intervals
3: no screen
4: no boot up
5: no startup chime

what do i do about it? any suggestions i should try on, actually there is no apple care anywhere near, its about 650 kms away.

I have uploaded it on youtube : you can see it here but i dont know if i should put up my link.

Can you try another charger? If it isn't a water damage...etc you may take it to :apple: or a local repair shop and have them check it for you.

seems to be water damaged and the first one when earthed shows a voltage of 13.1
battery Pins 3-6 Also Give 12.8 V without magsafe and even with magsafe.

some other updates:

1: battery has been charged completely
2: another thread opened by username jimanz11 yesterday has a similar problem, i taking cue from his pic have uploaded my readings here as well. (my readings are written in white) and taken after attaching magsafe
3: the white fuse near the battery conecter shows 0.5 ohms
4: magsafe board shows 0,17.3,3.35,17.3,0 readings
5: magsafe brown fuse shows 0 ohms
