Lenovo yoga 730 blinking keyboard after failed bios update

2019-12-17, 20:27 PM

I have been enjoying my Yoga 730-13IKB for almost two years but I have had trouble with an USB hub that didn't start every time.

I saw that there was a new bios version and I updated to IYCN40WW (v2.07) but it failed during flash of the bios after a short while.

Now the only thing my Yoga will do is to light up the keyboard for two seconds and turn off for 3 seconds.

I am not able to start the PC - I have tried holding the powerbutton for 20 seconds and it turns off.

Can someone help with my problem?

 

Regards

Jesper

Hi Jesperwtw,

Welcome to Community Forums!

You report BIOS(1YCN40WW) issue cannot be updated. But no enough information for our analysis.

Could you help to provide screenshot of "MSINFO32.exe" and "Winver" in cmd? It will let us know what causes this issue

Step;

  1. Click “win” key
  2. Type msinfo32 then press enter
  3. Click “win” key
  4. Type winver then press enter.
  5. Take screenshot and post to forumthanks.

BTW, you can try to update BIOS via Lenovo Vantage/System Update tool. Lenovo Vantage can be downloaded from the MS store.

Hi Keson

 

thank you for answering my message. 

I am not able to get the PC started. The display is black. Only sign of life is the blinking keyboard. 

Regards

Jesper
