Y520 Random freezing when plugged. Low battery notification.

Hey,

 

My Y520 randomly freezes. Screen just freezes where it was, sound goes silent, keyboard and mouse are unresponsive. When I unplug / plug in charger or close/open lid the computer starts functioning normally. 

Also sometimes there is low battery notification when the computer is plugged in. 

 

What's the issue? I had motherboard replaced twice because of that issue and low performance. It seems like performance is good now, however other issues are at the point there were when I bought the laptop.

Hello wobbly!

 

Is this windows 10? Use windows search and type Lenovo vantage, this allows users to run device diagnostics and driver updates. If not found, here's how to install: https://support.lenovo.com/us/en/solutions/ht505081.

Yes, Windows 10. No errors - W3BKNXL977MX-1VDUJZ code.

System up to date.

 

Recently low battery notifications turned into laptop just going sleep mode. Event viewer shows it was due to battery getting to critical level. No change in freezes tho. They happen more often while gaming.

Found out that freezing happens only when HDMI connected.

Sleep when low battery happens with and without HDMI.
