Lenovo Yoga 520 not charging

6 months ago I bought a Lenovo Yoga 520 14IKBR, and now it won't charge any more while turned on. If we plug it in, the led goes white - and starts flickering orange after a few second, the computer seems to think that the power is not plugged in, and the battery doesn't charge. However, if we first switch off the computer, and then plug it in, it does charge normally. I guess therefore that there is no hardware problem, but a software issue.

Somewhere on the internet we found a similar story, and according to them the solution would be a BIOS update. And indeed, the computer says there is a BIOS update waiting to be installed.

However - because the computer thinks that the power is not plugged in, the BIOS update refuses to install - 'please plug in power'...

 

So ... first question is of course if that BIOS update would indeed solve our problem. If not, is there another solution? If yes, how can we install that BIOS update safely while the computer thinks it is on battery power?

Re: Lenovo Yoga 520 not charging

Sorry, but that is not an answer to my questions. I do know how to find and install updates. But if the computer is running and plugged to wall power, it thinks it is running on battery power. And because it thinks so, it will refuse to install the update.

 

(as an aside, other brands refuse to install bios updates when there is less than 10% battery power left. That is perfectly reasonable, as running out of battery power during a bios install can/will brick your computer. But with 90% left??? That should be plenty to install and reboot safely.)

Re: Lenovo Yoga 520 not charging

Hi gert4!

 

Welcome to the Community,

 

Even installing the updated BIOS using the Lenovo Vantage will require you to plug the charger, regardless of the remaining battery percentage. Just to clarify, you mean the laptop only charge when in off state? While the charger is plugged when the laptop is in power on state, what is the battery status in the taskbar showing? Is it plugged in / not charging, or no changes on the status as it's like running in battery mode? The article below might help in fixing the issue,

Update us how it goes.

 

Regards,

Re: Lenovo Yoga 520 not charging

I have the same problem as the person above:

 

The Yoga520 charges normally when turned off but in windows it stops charging after a few seconds after being plugged in.

Pluging in the charger causes the icon to change to plugged in and charging. It then quickly changes to on battery power and the battery icon. Lenovo Vantage says that the battery is healthy

 

 

Updating bios is not possible as it refuses to install on battery power. Any way to ignore this.
