Hey there ! This may sound like a sad joke but this actually happened to me. You have the right to laugh as loudly as you want as long as you give me some help :-p Last week my cat was sick, his nose was spilling a fat clear liquid almost everywhere in my house. The problem is that he decided to sleep on my laptop… Now when the computer boots, the fan is enabled even before I can see the white screen. It starts loading my system and then shuts down. It won’t boot again unless I remove the battery connector and put it back in again. Also when I plug the battery charger in, the led lights up very very weakly so I guess that something’s going wrong here too but i’d like to fix the 1st problem 1st :) I guess that there is some matter on a sensor which leads the computer to turn into security mode. May you help me figuring out whats going on ? As long as it turns on, i suppose that it’s only a sensor problem but i don’t know where they are located so I can’t clean it yet… Thanks in advance !
My unibody macbook 13" late 2008 keyboard was spoiled with water for a while. Result was a failure of a part of the keyboard. After securely drying and cleaning most of the keys started working again except 1 key » the left shift-key stays permanently in Uppercase mode and isn’t working anymore. This failure resulted in booting only in security mode (holding down the shift-key forces a Mac to boot up in security mode!). To bypass this and boot in normal mode I have to hold down the esc-key during start up until apple logo shows up. With KeyRemap utility I have to disable the left-shift key in order eliminate Uppercase. In my case the security boot is a keyboard problem.
