Lenovo y-480 charging problem

Hi! Im having a problem with my laptop.

I actually have a Lenovo Ideapad Y-480 and the problem is that when Im using the laptop in a normal use like AutoCad or Revit programs everything is fine but when I start playing a game the system stops charging out of nowhere, I dont know whats happening I checked the energy management settings and everything is normal and I have my system in high performance settings. Also I checked the charger but it seem to function normally and it also happens when I use another charger also from Lenovo.

Please if someone knows how I can solve this problem I would really apreciate it because the system performance drops a lot when Im not charging the system and the battery lasts just like for 20 minutes.

Re: Lenovo y-480 charging problem

Hello Emiliomnz


Thanks for using the Lenovo forums.

Sounds like this could potentially be a faulty battery issue, as this should really not happen.

 

How long has this been going on? Is this recent or has been happening for a while?

 

Also, try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

Hope this helps, let us know how you get on.

Re: Lenovo y-480 charging problem

No sir the problem is still there, my battery is in good shape I can use my system normally.

I currently have a charger with 20v and 3.5 A  but at the bottom of my laptop says I need a charger with 19.5v and 6.15A could that be the problem?

Re: Lenovo y-480 charging problem

Try to flash bios update and update power management drivers first.

Also, is your system getting hot?

 

Update us how it goes.

Re: Lenovo y-480 charging problem

Welcome to the Lenovo Community  Emiliomnz !

 

"I currently have a charger with 20v and 3.5 A  but at the bottom of my laptop says I need a charger with 19.5v and 6.15A could that be the problem?"

 

Most likely it is the source of your problem.  A 20V - 3.5A charger / adapter is only 70 watts of power.  According to the Hardware Maintenance Manual for your model, your laptop requires either a 20V - 4.5A (90 watt) or 19.5V - 6.15A (120 watt) charger / adapter. 

 

A 3.5A charger / adapter will work if you are charging the battery with the laptop turned off, but if the laptop is powered up and running software applications, it is under powered.  During normal Internet browsing the 3.5A charger / adapter may have enough power to power the laptop and may even put a charge on the battery.  Under a full load like gaming,  the 70 watt charger / adapter is having a difficult time keeping up with the power demands of the laptop and the laptop is probably drawing on the battery for additional power requirements.  I've seen laptops with under powered chargers completely drain the battery and shut down when plugged in. 

 

If you do a lot of gaming I would recommend the 120 watt charger / adapter.  It will not only charge your battery faster, but it will provide sufficient power when you have it plugged in and are gaming.
