My laptop said fan error and just shut off. I removed the keyboard and blew the fan and now it won'tt turn on period

Bill:

Drying the keyboard with a hair dryer was not a good idea... Under the keys are layers of mylar with the circuits for the keys printed on them. If the mylar got hot it wrinkled and the keyboard may have been ruined. Try the keyboard after the batteries have dried, and if it does squirrely things, you'll probably have to replace the keyboard.

Laptop abuse, your luck it will work at all. It sound like it's done. You may have killed it

The laptop must be taken apart and cleaned, remove fan and heatsink get a can of compressed air attach straw, now give a good few blasts to the heatsink fins to remove the dirt including fan, Next get rubbing alcohol and clean the old thermal paste from the processor and heatsink, when finished apply fresh thermal compound to both items and assemble.

When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

Hello Friend,

• Do you find that the keyboard and the bottom of the laptop are very hot? Or the cooling fan of the laptop is noisy? Or the laptop suddenly shuts off but no warning and error message? Why?
• That may be the problem of the cooling fan and heat sink. They may be dirty, and failure to maintain cleanliness on the inside of the box can and will result in overheating, and sluggish performance due to high temperatures.

To clean : 1.Remove the keyboard, access the cooling modules (fans and heat sink), you do not need to disconnect the keyboard, just place it face down on the palm rest.

1. 
   
2. 2. Spray compressed air inside both cooling fans and sink heat. You can use canned air sold in any local electronics store.
3. 
   
4. 3. Connect the keyboard.
