All I get while computer is plugged in is a blinking power button

"Hey

I just $!^& blocked by this error today and tried some ways to fix this, first close the lid and insert the power plug to see the led light, the open the lid while the power plug is connected. Push and hold power button and Start button for 15 seconds. When in blinks white unplug the power cable. Don't do anything and wait for 1 minute, open the back door of the laptop and disconnect the battery then dismount the Ram. Wait for 1 minute. Reassemble the pcis and plug the power to the laptop without doing anything. Wait for 1 hour and then unplug the cable, now push the power button regularly. It worked for me."

hi, be careful downloading latest lenovo updates , especially bios , when you thinkpad is supposed restart, my thinkpad E15 didn’t . This is the second time, now i have a fixed red power light , a fixed white esc /fnlock white , and a white power light and im still waiting for a call back, after a lengthy service call from Indonesia?

Same issue here with a Gen 8 Carbon X1. It seems to be caused by a faulty battery. Sometimes the pin hole reset works and gets you back up and running (putting a paperclip in the small pin hole at the bottom of your machine). In my case it required a battery replacement to get it fixed.

I didn’t have time to remove the battery last night. So, I closed the laptop and moved it to another power source and left it plugged in all night. When I opened it today it booted up!
