Hi khatana,

Please check if there is any indication of power on the system and the ac adapter when you turn on the system. If there is no power, please follow the steps provided below.

Connect the ac adapter to a known good power outlet. Check the power LED indicator on the ac adapter (without plugging it into the laptop)

If the LED on the ac adapter is not lit, please reseat the power cables to the brick. If there is still no light coming up on the ac adapter, it would mean that the ac adaptor and the power cord may be faulty.

If the led on the ac adapter is on, then remove all external peripherals, switch off the system, and remove the battery, ac adapter and the power cable. Press and hold down the power button for thirty seconds to drain any excess static power.

After performing the above steps, and if there is no power on the system then the motherboard may be faulty. You can also try reseating the memory and check if the issue persists.

To remove and reseat the memory using the link below

In this link punch in the system service tag or express service code and you can access the user manual.

Let me know about the progress.

try to get it into ePSA mode, think it's hold Fn key - power button or press d - power button
