Wont turn on

[Nick palin]

So my Lenovo yoga 2: model: 20344 will not turn on, I accidentally put the power cable into the USB port and bent the pins inside slightly, the computer turned off. I try to turn it on now and all that happens is that the keyboard lights come on then go straight back off a few seconds later. The screen does not come on at all

Hi,

Please do try these troubleshooting steps that may help.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If this will not work, do test the AC adapter if it's working properly. Remove the battery and power the laptop with just the AC adapter connected and see if it will boot up or not. do also try a different AC adapter that has the same voltage and see if it will work or not.
- Proceed with reseating the RAM's if trying a different AC adapter will not work, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If it will still not work, connect an external monitor and see if you'll get any display from it. If there's a display on the external monitor that could mean that the problem is the built in display.
- But if there's still no display on the external monitor that means the problem lies in the motherboard.
