Lenovo X240 Won't turn on

Hello, so I have a Lenovo think pad x240 as issued by my high school and I was using it last night and tried to power down by pressing the power button as I was in a rush but that did not work so I shut it down normally and now I am trying to turn it on and pressing the power button is not working, it definately has battery because I plugged it in overnight so I think the power button may be faulty, I have only had the laptop for 2 years. And yes I have tried the "secret code" trick but that does not work - presumably because my laptop also has an internal battery.
I need help asap!!!!! Thanks in advance

Hi nstock98,


Welcome to Lenovo Forums!


Kindly request you to try with the below given troubleshooting steps.

Remove the battery and AC adapter

Remove the hard drive and wlan/wwcan cards

Remove both RAM modules

Re attach the AC adapter and boot

If you don't hear a series of loud beeps it probably means a hardware issue.


Please let me know whether the above steps helped you.          

Thank you, have a good day.

Usually removing RAM is enough that shall make the laptop to start beeping Smiley Happy wlan and so doesn't need to be taken out to get beeping sound
