I would suggest you drain the residual power from the laptop. Disconnect any external peripherals (flash drives, printers, external hard drives) from the computer -> remove the power cable -> press and hold the power button for about 10 seconds -> reconnect the power cable and check.
If the issue persists, I would suggest you to remove all the memory modules and reseat the graphics card (if available) from the computer. Put one RAM at a time and check if there is any change. Ensure that you check in all available slots with just one RAM.
You may refer to the service manual . Please ensure to follow the safety instructions.
Please reply if you have any questions.
Thanks and Regards,
Dell Studio XPS 435mt lights power indicator but won't boot.
2 or so years old Dell desktop is down and not wanting to come back up. Fans are off.
When I press the power button, the power LED blinks orange, otherwise it's off. Windows 7, sp1 I think, 6 GB RAM
Are there any answers or advice for this one?
