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 !
