my friends x61s (1.4Ghz) doesn't start.
When the power button is pressed some leds blink couple of times as normally, but the screen doesn't show anything. After couple of seconds the leds stop to blink and only one led stays constantly on (besides the power) see the picture below:
There are no beep codes.
The screen remains off all the time.
The fan seems to work (not loud but working)
There are no signs that the OS is being loaded (in case of faulty screen).
Replaced RAM and HDD to test, no difference.
When I were trying with different RAMs there were beep codes for some of them.
I have tried both with and without battery.
I suspect that some thing was fried inside.
Your comments and tips are highly appreciated.
