Lenovo x250 won't power up

[Bracom]

Took out battery. Hit power button 10 times etc but no signs of life except for power button flashes green 3 times before nothing else happens. Tried to start with battery removed. No luck. Ideas appreciated!

Hi,

Here are some troubleshooting guides that may help in solving the issue.
- Start by removing the battery and boot it up with just the AC adapter connected and see if it will boot up normally.
- Next is to test the AC adapter if it's supplying enough voltage or try a different AC adapter that has the same voltage.
- If it doesn't work proceed with reseating the RAM's, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If you'll see lights on the laptop and you can hear the fans spinning, connect an external monitor and see if you'll get any display from it because if you do that means the problem is the built in display.
- You may need to check the ribbon that connects the LCD to the motherboard.
- If all these will not work the problem would be the motherboard.
