Hi, I have a Thinkpad T430. It was running very hot as of lately, so I decided to clean it up. I had never opened to machine, and I very rarely deal with laptops so I don't have much experience. I removed the keyboard and the palmrest which gave me access to the fan. I didn't disassemble any further as I just wanted to clean the dust off it a bit. I passed a vaccuum and a few sheets of paper and it looked much better. I didn't touch anything else. After assembling it and plugging it in, it didn't boot. The power button lights turned on, along with the microphone and audio mute buttons, but the screen was black. I tried to connect to an external monitor and it didn't display anything. I decided to disassemble it again to take a closer look at what might be wrong. Upon closer inspection, I realized the fan didn't spin when I turned on the machine. My guess is that the computer prevents itself from booting when the fan isn't spinning to not burn itself. But I have no clue on why it doesn't spin. When cleaning, I didn't use any sort of liquid, I didn't break any cables or get anything out of place, I did manually move the fan to be able to clean it completely, but nothing more. I didn't feel ecstatic so I don't think I fried anything with my fingers. The HDD does spin, but I don't see any other reaction from the computer. Please help, I'm shaking, I really really need this conputer.
