Sony Vayo pcg-81111v BIOS issue

[ezisspb]

I have Sony Vayo pcg-81111v

I changed HDD to SSD and want to install new OS on SSD.

But I can't access BIOS!

I tried all key combinations(F2,Assist,F3,F11,F12,Del,ESC)

I removed CMOS battery, I removed HDD, RAM and everything. 

It still showing Operating system not found

Even when I turn on pc without CMOS battery.

Please any help?

Have you try to keep F2 before and after the Power button?

[ezisspb]

Yes,ofcourse, I tried all options, 

I even succeeded to enter one time in BIOS using F2 button, after removing CMOS battery. Than I turn off pc, tried again and I see only Operating system not found.

Ok but, F2 keep pressed before the Power or pressed only after the VAIO Logo?

[ezisspb]

Pressed before, pressed once when logo appears, pressed multiple times when logo appears, starting pressed multiple times before power on etc.

Ok so... You have ti replace the HD with the old one and, if there are an SO, entering in the BIOS by him...

I think I find a reason. That was simply a keyboard issue. Old keyboard some buttons doesn't work.

Thank you for your time.
