Have a Sony Vaio PCG-FR130 (Model PCG-9H4L on label on bottom of unit) which does nothing at all when the power button is pressed. Have checked the switch on button and seems ok. I have also removed the CMOS battery from the unit and still no change. CMOS battery is 3V. The AC adapter is outputting 19.48V DC. I have tried with no battery and AC and battery only.
The laptop was working fine one day and then the next there was nothing when the power button was pressed.
Any other suggestions where to look or a service manual for this laptop would be appreciated. Thanks
