Thanks Rohan. All the issues are intermittent.
The LED of the system turns off, however the issue is intermittent. At times the LED is on and some times it's off.
I have tried releasing flee power however this does not help.
The system is not covered under warranty.
Here's the summary of the issue again.
The power turns off automatically while working.
The laptops does not get started and it's a matter of sheer luck when the system will work. The system work only 1 out of 20 times the power is switched on.
Also the numpad on the laptop does not work properly.
Regards,
Samir
