I turned that laptop on and it wouldn’t connect my second monitor so I restarted it. After the restart it wouldn’t turn back on at all. I hit the power button and the red power light would turn on for 1 second and shut right off. I unplugged everything but the power supply and same thing, the red light would turn on and turn off after 1 second. I opened it up and removed the battery and tried starting it with just the power supply and just got the same results.
