The Lenovo G50-70 can be identified by model information printed on the bottom (model name 20351), or on sticker next to track pad. This laptop has a 15.6 inch screen with Dolby audio. Manufacturing began in 2014.

@lcxbnr thats good to know that a CMOS battery can cause that type of issue.

What did you clean the connector / wires with? When it blinked, did the screen go off and then come back on? I know that RAM issue can cause some strange things to happen such as display and no boot.

Does the charge light come on when you plug in the power adaptor?

If your pc has two sticks of ram take them out and boot the laptop up and see if it posts. If so then test each stick of ram by placing one in at a time.
