Samsung Laptop R418 suddenly went off without any error on the screen
Received another Laptop for the problem as stated above. On inspection I found this laptop went off suddenly without an error on the screen.
First I have doubt about the adaptor I have checked the Voltages on my meter I found 19V on it, but if adaptor is having problem inside and that may causing the symptom(Customer already informed me about the Battery is no more working and does not Hold the power). Hence I have checked the laptop with another working power adaptor.
Still the problem is same it goes off any time.
So now it is time to diagnose the problem inside the laptop.
After opening the laptop I found too much dust on the PCB and CPU FAN full of the dust.
This is first rule for computer repairing is – it should be free of Dust because due to insufficient air exhausts of hot air will create the problem to functionality of the computer.
Hence my first priority to clean the laptop from inside.
Dismantled the CPU FAN for cleaning and re lubricated it.
After all cleaning process I have reassembled the Laptop and kept it for burn-in tested for 5 Hours it works smooth without any problem.
