I'm trying to increase my dedicated video memory and to do so I need to open my BIOS but when I try to my monitor remains on standby (it automatically turns on along with my PC) and nothing happens, the screen remains off and BIOS doesn't open nor windows so I have to manually turn my PC off with the button. The BIOS key for my PC is F1 but i've noticed that pressing delete, f2, and f12 cause the same thing to happen during startup. I went to the Lenovo site and checked for an update however the site says that the H250's BIOS is up to date so there are no updates available. Anybody know what is going on? Has this happened to you? Any solutions?
I have Windows 8.1, it came originally with windows 8 but BIOS didn't work with 8 either. And I can't launch the BIOS from Windows as I have no option to do so.
