Lenovo Y580 Troubleshoot

2013-02-20, 5:29 AM
I just purchased a Lenovo Ideapad Y580 laptop, and I am not sure how to optimize the laptop to be able to play games using the full capacity of the laptop. I notice that when I have the laptop charged, games like Borderlands 2 play perfectly at 1920x1080, but when the charge is unplugged frame rates start going all over the place. Could someone help me fix this.

hi i8yourfriend,

 

Welcome to the Lenovo Forums.

 

Your issue maybe similar to this and  this thread.

 

When you plug-in the computer to an AC power, the PC gets all the power that it needs to run the CPU, GPU, HDD, LCD, Memory, and other peripherals to its maximum performance.

 

The minute you unplug the AC adapter, all the power will automatically route to the 6-cell, 72Wh Lithium Ion battery. This power source is not enough especially If you have a dual GPU like the Intel HD Graphics 4000 + NVIDIA GeForce® GTX 660M. The GTX 660m alone uses 50W (source here) on stock clock speed and it still need to power the other PC components and peripherals.

 

To ensure maximum performance when playing  games or running any graphics extensive application,  the computer must be plugged-in all the time to get adequate power.

 

 

Hope this helps.

So currently there is no way to fix this issue? I feel like I was mislead or something. This is a laptop it is suppose to be portable and be able function according to the owners needs with or without a charger. Why would Lenovo ship their laptops with a battery that would throttle the laptops performance that is just mind boggling. Isnt the point of it to be portable. I am so frustrated, this is my first time purchasing a laptop from Lenovo seems very likely to be my last. Thanks for the info.
