Hello sir,

I have a problem on my laptop. I removed my keyboard while the power is on. The power turns off automatically. I tried to turn it on. For a few seconds, the exhaust fan starts to rotate and shut off again. The laptop never powers up but there is a light on the lower part where the built-in mouse controller is placed. how can i identify the source of the problem. Is it the fuse of the motherboard? How can I replaced it?

Thank you sir in advance..
 

This could be due to either a short circuit on the mother board or overheating of the processor.
 

Hi,
I thing , it may be getting i/o chip short .....because keyboard is connect to i/o chip.
Try for this methods
1. Remove battery form laptop, connect power adapter then on now,,,,,, if not..:roll:
2.press & hold power butten 2 min with connect battery....if not :roll:
3.finally replace i/o chip :-| (better give to laptop chip level service center.....for this,, )

Don't remove or plug any i/o parts (keyboard, touch pad ,some model laptop battery, camera ,)
