Lenovo y50-70 bios password and keyboard

Hello!

 

I have a question. 

Friend of mine gave me this pc (y50-70), everything works fine, can't say anything bad. But the problem is about my bios password and the keyboard. When i try to enter bios it asks me for system password. Asked my friend about it, but he never tried to enter bios. Quetion is, can i change/remove bios password? 

 

About keyboard, every few minutes to 1 hour my A and S buttons stop working for some time (2mins-30mins). And then randomly start to work again. What's the issue? how can i fix this? (When I was writing this text these keys stopped working several times).

 

 

Sorry if these questions have been asked before, im pretty new here.

 

 

 

Thanks in advance.

There is no "backdoor" BIOS passwprd.  The only choices are to remember the password or change the motherboard.

 

It sounds like the keyboard is failing, maybe when warm.  Normally the problem requires a keyboard replacement, but sometimes compressed air can be used to blow out things like crumbs and pet hair.

Hi AlexReed,

 

Welcome to the Community Forums.

 

You can change and remove the password only if you can place the original password that was placed on the BIOS.

 

As explained here on the hardware manual page 24:

 

"Administrator password controls the access of the whole setup utility. Only Administrator password was set then User password can be set. If Administrator password was cleared, the User password was cleared too

 

About the keyboard, try to check with another external usb keyboard or onscreen keyboard to isolate a possible hardware issue.

 

Update us how it goes.

 

Regards

Re: Lenovo y50-70 bios password and keyboard

Well.. I don't know the original bios password, I guess only way is replacing motherboard then.

 

About keyboard, I can type A and S on on-screen keyboard.

 

 

And another problem has showed up now, dedicted video memory.  I can not enter my bios without password then how can I increase my dedicated video memory? When i got this pc i had 2 gigs, but when i installed windows 7 on this pc I had only 64mb? like what.. I googled too and found some regedit (Intel --- GMM --- value) thing, but it did not help me. Is there any way increasing it without bios? Or is it dead end?
