Hi heartbeattt,

 

Thanks for posting and welcome to the community,

 

You might want to consider updating your BIOS and the  Lenovo PowerManager, The links can be found below.

 

BIOS : http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS027242

 

Lenovo Power Management : http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS027354

 

I'm not entirely sure what is gong on with the system but I'm suspecting that it could be a software conflict. Please do give that a try and let me know of the changes.

 

Regards

Re: y570 GPU SWITCH AND WIFI SWITCH ISSUES

as for the lenovo power management you linked, it said i have the latest version of it already.

and as for the bios, when i open the .exe file, it says 'the version of ROM file isn't newer than that of the BIOS' which im guessing that i have the latest version of BIOS as well..

the problem still has not been fixed.

something else to add -
just hitting the gpu switch turns off both usb 3.0 ports on the right.
does not matter if you go frmo ON to OFF, or OFF to ON, if i hit the switch it WILL shut down the two usb ports on the right.

what is this.. i've only had this laptop for a week.

Hi heartbeattt,

 

Sorry for the delay in reply, just been tied to a number of cases. Was checking up on your case and was wondering you might want to try going into your BIOS and load the system back to optimal defaults and then check for the changes. 

 

On another note, was there anything that you had installed prior to this issue happening?

 

Do let me know of the changes then.

 

regards

Hi heartbeattt,

 

Thanks for posting. TO access your you BIOS is quite aeasy. Now I do not have a Y570 with me but I will be guiding you base on the Y580 I have. It may not be too far abaprt in terms of the configuration menu.

 

  • Boot your machine and upon seeing the Lenovo Splash screen hit the "F2" button. This should direct you to the BIOS setup screen. (See illustration below.)

  • Once in the BIOS, go to the Exit Tab. There you will be able to see the "Load Optimal Defaults" (See illustration below)

  • Select the last setting "Load optimal defaults" and hit the F10 button to save the changes. Let the machine reboot and once the machine goes back into windows check for the changes.

Hope this helps and please do let me know of the changes.

 

Regards
