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

"Hi @jason11 ,

A blinking power light is an indication that the laptop is in sleep mode.

Try either force stopping and shutting down the laptop by holding the Power button until it shuts down completely and then restart the laptop in the normal way

or

Try opening and closing the lid a few times and check if the laptop comes out of sleep mode by itself.

Hi @jason11 ,

Can only suggest to reset the BIOS to default in case there are any corrupted settings which may prevent the laptop from functioning correctly.

To do this open the laptop and remove the battery pack and the RTC battery, press and hold the Power button for 30 seconds and then release the button and then replace the RTC battery and the battery pack.

Hopefully by doing this you will have reset the BIOS to default settings

Here's a link to the service manual for the laptop, taken from this webpage.

Scroll to p.40 to view the necessary pre-requisite steps and then the procedure on how to do this.

After you have done this, reconnect the charger and check if the laptop starts to charge correctly.

If it still won’t charge then you have a motherboard problem

If it starts to charge allow it to charge fully before attempting to start the laptop.

If it starts OK allow it to boot all the way to the Windows desktop and allow the HDD activity to settle before checking things.

If you have Win 10 installed check if you have the latest chipset drivers and latest power management drivers installed. Click on the “see files” arrow to view details of driver version and release date."

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!
