I have pretty old (5 years) Asus x542ba which I decided to clean its fan and change the thermal paste.
I have removed the keyboard, the battery, the hard disk, the DVD unit, the fan, the main board and lastly the heating on he cpu, under the main board.
I cleaned the old paste from the CPU and the heatsink and I noticed the CPU was integrated inside the board (didn't have a socket) and had a translucent orange "sticker" between the outside of the CPU and the heatsink. I removed it because there was some thermal paste under it.
I put it all back together and it doesn't turn on anymore, but in a really weird way: when it's not plugged in, just with the battery, there is no power led, no nothing, it's completely dead; when I plug it in it wants to turn on, the power led is on, the the battery led is on (as it is charging) and the hard drive led blinks twice. After that second blink I can suddenly hear the HDD turn of, just like when I force a power off and the other leds turn off as well. Even more interesting is the fact that in both cases the fan doesn't start spinning at all.
The paste I used is Thermal Grizzly Hydronaut, which is not conductive.
I disassembled it again quiet a few times to check I didn't forget anything, I reseated the RAM, I put back the "sticker" on the CPU, I checked all the ribbons and I ried with and without the battery connected.
