Check the RAM module(s):

If the above does not help try the CMOS reset procedure:
Power drain + CMOS reset: Open the back of the laptop and disconnect the battery cable from the motherboard. Locate the CMOS module under the SSD (with 2 twisted wires Red and Black) and remove the coin battery. Shorten the +/- contacts (terminals) inside the CMOS capsule for 2 seconds with a bended paperclip and put the coin battery back with the + sign facing up, close the CMOS capsule. Next, press the Power Button on the keyboard for 10-15 seconds after that reconnect the battery cable to the motherboard. Close the laptop, plug-in the adapter and try to boot.
