S400 won't turn on after overheating

2015-02-25, 17:30 PM

Hi all,

 

I have an S400 that I bought back in 2013. It is no longer under warranty. Recently I thought the fan was a little weak but I thought nothing of it. It overheated and turned off for the first time about two weeks ago. I let it cool off, and then restarted the computer with no problem. After making sure all was working correctly, I turned my computer off completely and went to bed. The next morning, the laptop would not turn on. It has not turned on since.

 

I have tried taking the battery out and turning it on with just the AC adapter, I have tried draining the power  completely with the 30-second holding of the power button method, and I have taken it to a friend who is an electrician who has confirmed it is not power-related whatsoever.

 

I took apart the back, and found that my fan was clogged with a ridiculous amount of dust as well as stuck on a broken fan blade. I removed the broken piece and cleaned out the dust. 

 

I have not yet put my computer back together as I am wondering if there's anything else I should look for from here.

 

Thanks.

Welcome to the Lenovo Community !

 

If you haven't given it a try since finding the stuck fan blade.... I would try it now.  If the fan was stuck it may have prevented the laptop from starting up. If the laptop now powers up with the fan free then I would suggest you replace the cooling fan.
