Hello, Split water on macbook pro. Machine gone off. Tried to dry it fora few hours. Machine did not boot up. Opened back cover. Removed battery, hard drive, ram and fan and dried water. I did not move to remove cdrom drive and motherboard and keyboard. Tried to start up Macbook Pro. Before cleaning, MBP did not boot no matter what. But now MBP boots up but laptop screen is OFF. I attached the HDMI Thunderbolt cable to my external monitor. Now I can see gray blank screen on my external monitor. I can drag the mouse to external monitor and move it. Probably I am on login screen. But login screen is activated on my laptop screen. That is why I see blank gray wallpaper on my external monitor. So, how can I make my second monitor to be active login screen so that I can put my login credentials? Or should I go and remove and dry cdrom drive and mother board. Actually I need to access HDD to back it up, rather than fixing the laptop screen. So I should not risk it losing by doing something wrong while touching motherboard or something. I have also macbook air at hand. Can I put my MBP 2011 hard drive to latest Macbook Air. How can I make my Macbook Pro hard drive to be read by Macbook Air? What do you recommend please?
