Lenovo Ideapad 520S-14IKB battery draining when powered down

2018-10-25, 19:34 PM

Hi there, just over a month ago I bought a Lenovo Ideapad 520S-14IKB for my other half. It's a really nice machine but we've been observing something unusual: when you power the laptop down it's losing 20%, sometimes more, over night. For example I switched it off yesterday night at 94%. This morning it had 70% left. It's properly powered down, not in stand-by or anything like that.

 

Looks like a battery problem to me but before I send it back to the retailer I just wanted to make sure there isn't any setting or anything that can be deactivated/activated to avoid this. Please let me know.

 

Thanks

 

Lars

unfortunately turning off Fast Startup has not made any difference. I also checked and "Always-on USB" was deactivated out of the box (read in another thread this could cause the problem).

 

I was just away from home for a week and the laptop was fully charged before we left. When I got back it would not turn on because the battery was dead.

 

Any other ideas?

Hi Lars14,

Is the laptop no longer turning on? If so, have you tried plugging in the charger for at least 30 mins before turning it on? If you are able to turn it on, could you please try to update the BIOS? Please download the BIOS firmware here https://support.lenovo.com/us/en/ (please enter the serial number and go to the Drivers & Software tab, then select your OS and look for BIOS firmware). Ensure that your laptop is connected to the charger while updating the BIOS to make sure that it has enough power. Let us know how it goes. -Maru_Lenovo

Ok, updated the BIOS, there was indeed a new version available, but no change. We now have fast-startup disabled, USB-charging when switched off also disabled and a new BIOS.

 

Anything else I could try before sending it back to the vendor? It's a real pity because I really like the computer and it's not available at the vendor anymore :/ They have already offered me a return and money back but I'd much prefer to get the computer to work :/
