My Laptop model is Toshiba Sattelite L645D. I bought it from USA 2 years ago. It was working fine. But now there is no display when i turn my laptop on. Laptop fan is also not running while the power is on. I checked my RAM on other devices and Ram is okay. I removed laptop battery and tried but same problem. No display. I also tried external monitor plugging it but no display in monitor also. Then i tried removing power adapter and battery and then hold the power button for 60 seconds and same problem happened when i plugged my power cable.
