Yoga 710 light flashes won't boot.

Hi there, frustrating problem of Lenovo not being able to boot up. The light will flash, but no action.

 

- If I can hold the power button for 15 seconds the fans will spin for a few seconds.

- I've opened the back and removed the battery

- checked all connections

- I've tried running of AC adapter

- tried removing ram

 

Anyone got any suggestions?

 

Removing the battery did work the first time (thought problem solved), but it happened again on next boot and it hasn't worked this time.

 

I was advised to reset the bios but can't find the battery, seriously hidden little sucker...

 

Thanks.

Re: Yoga 710 light flashes won't boot.

So Im pretty sure there is no CMOS battery and it uses something else (capacitors?).

 

Anyway I updated the bios from https://pcsupport.lenovo.com/au/en/products/laptops-and-netbooks/yoga-series/yoga-710-14ikb/download...

 

Which got it started. But now when I turn it on it runs for 1-5 mins before crashing!

Boot into BIOS without loading the OS.  See if it stays on. 

 

If so, Boot into Safe Mode. See if it stays on.

The good news is that lessens the odds it's a hardware issue.

The bad news is something's most likely screwy with Windows.

I THINK you can get to System Restore from Safe Mode and try rolling back Windows to a restore point where it was working. Otherwise, there are a number of ways to repair Windows or just hit the Novo button and reset everything.

Not starting again, same flashing light no action. This thing is the devil.

Re: Yoga 710 light flashes won't boot.

If you can still get into safe mode, have a look at the Event Viewer under System and see if there are some error messages that could help diagnosis this.

 

Though it sounds like a fairly wrecked Windows installation. Might be time to hit the Novo button and reset everything.

Re: Yoga 710 light flashes won't boot.

Hello - I tried all of the solutions and still have a brick with flashing lights.  The power light is on but the screen is blank.  I have removed the battery as suggested and when I plug the unit back in the power light comes on but still a black screen.  This all happened after installed windows 10 updates on the machine. 

 

Any ideas?  Thanks

So, nothing even using the NOVO button?

 

You should probably list everything else you've tried so we don't waste time suggesting things you've already attempted.

Re: Yoga 710 light flashes won't boot.

Sorry.  Here is a Summary.

 

Downloaded latest updates for Windows 10.

After updates screen went dark, power light lit.

Tried to wake system using keyboard and mouse - nothing.

Pressed and held power button to reset - power light stays on - screen remains dark.  No sounds

Opened cover, removed battery, held power button for 30 seconds, plugged in cord - power light comes on but screen dark.

Repeated above, plugged in battery - power light comes on but screen remains dark.

Power light flashes once every now and then.

When power cord plugged in the light next to it is orange. 

No other life signs.

 

Thanks for any help.
