Hi everyone
I have a Dell 17R SE 7220 laptop. I regularly clean its heatsink and fan assemble every 2-3 months to keep it running cool, because once the GPU was fried up and was replaced and serviced by Dell. My laptop is still under warranty.
This time it had been a while since i did that, and the laptop overheated too much. Even when using Google Earth, it would heat up and turn itself off, GPU temperatures soaring above 90 degrees Celsius..
This one time it got shutdown while i was away. I came back and found it off. Thought it would be another overheated-auto turn-off. I started it up, but then it refused to start up.
When i press power button, the keyboard lights up, the quickset buttons blink, the Power/HDD indicators light up. and in 2 secs it turns off. The fan does not start spinning though. But that might be because the laptop doesn't get heated up enough for fan to start up. I have checked again for any loose connections, reseated HDD, RAM, Wifi, SSD etc (the ones located just inside the backboard, easily accessible) but nothing works. I tried it both on battery and AC power. I also tried discharging everything by removing battery and holding power button for 30 secs, but doesn't work.
I've checked the forums. Somewhere it says that CPU pins mights be loose. Before opening it up again to re-seat everything on the system board, I'd like to know if there is an easy solution for this.
