I have a Sony Vaio VPCEB19FX, which has an A222GVPJ motherboard with AMI Aptio Version 1.28.1119, BIOS Version R0300Y8, EC Version K0300Y8, and ME Version 6.0.3.1195 ©2008 Legacy-type BIOS wi Version . I have seen issues reported with booting from USB in this BIOS. I have also seen some specific processor requirements (PAE, NX, and SSE2) and BIOS requirements (NX Bit). Some say non-UEFI BIOS will not work and others say it just limits Win 10 functionality. Others say that AMI BIOS will work and others that you just need to make sure the BIOS will allow a USB boot, by changing a hidden setting to allow the system to boot from USB. This computer meets all other Win 10 requirements, but there is no recent BIOS to flash and I can't see a way to turn on UEFI from BIOS. The manufacturer (Sony) doesn't mention this PC in "supported" PCs able to upgrade to Win 10. The computer is fast and smooth, for an old laptop. To the questions... 1) Is UEFI required? Does Win 10 require anything specific of BIOS? 2) Is the decision by Sony to not list my model due to drivers, UEFI, or just that it has not been tested and, therefore, not officially supported? 3) Is there AMI-specific problem upgrading to Win 10? Am I safe to upgrade from Win 7 to Win 10, with these things in mind? Please help! Thanks in advance!

Hi there, Recently my Vaio Laptop ran into a problem, and after many unsuccessful attempts, I made a big mistake - I entered BIOS via shift+restart keys in windows 10. I changed the boot option from UEFI to Legacy. Afterwards, my pc stopped with error "Operating system not found". I neither have access to BIOS settings nor to the windows. I recovered my C Drive (windows Drive) using my Acronis True image boot disk (a back-up software) ; although it successfully replaced my windows drive, I still have the same error "Operating system not found". I tried to install a new window 10 using Bootable flash, but didn't works. I had a windows 7 installation disk and tried to install that one, but when it comes to select drives to install, it mentioned that mine is GPT and it is not possible to install windows on GPT (Probably because of changing in bios from UEFI to legacy) shift+restart was the only way works for me to get to the BIOS, other familiar ways mentioned in this article " F1, F2, F10, Delete, Esc, as well as key combinations like Ctrl + Alt + Esc or Ctrl + Alt + Delete" does not work for me. "Assist key" does not work for my VAIO as I removed it from my HDD several years ago. I have a full Backup of my laptop from the purchasing day so am able to bring back assist functions. And maybe afterward my F1/F2/F3 functions well and transfers me to BIOS settings. Anyway, from that time now I changed some partition sizes and I have a purchased a software that worked with the code generated by the current size and info of my HDD. So If I use that scratch copy of my system, my codes and access to that products fails. Therefore, I am looking for some simple way to solve it. I remember from old days that BIOS settings back to default by removing motherboard battery. But I am not a technician and do not know if it is a good idea or not. I am wondering if someone has a solution the problem. Thanks for your time.

Hello I'm having a problem with my Sony VAIO model: vpcsc1afm. The issue is my battery has spotty performance. The computer runs perfect for when the battery is working but other times I will be using it and the battery light will start blinking and my computer will tell me that the battery isn't recognized (0% not charging). After the computer shuts down I can't turn it back on without taking out the battery and putting it back in. It's also happened when I was just charging it with the computer off. It will be charging and the battery light will start blinking and won't be able to turn on till I take out the battery and put it back in. I bought a brand new battery and it does the exact same thing as the original. I also completely re-installed windows and started fresh and it still is doing it. I'm thinking that maybe re-installing the BIOS will fix the problem. The bios is already updated so when I try to use the bios upgrade from Sony's website it just says the bios is up to date and won't install it. Does anyone know of a way to re-install the BIOS if there isn't an update for it?

Hi people. I made bad BIOS mod and now I need to recover my VAIO. BIOS chip on my VAIO F is 4MB size but it has 2 parts: EC firmware part and actual 2MB BIOS. This is why I need an Image token from hralth BIOS chip of VAIO F. Preferably VPC-F126FM. Can you help me? Either BIOS image or BIOS chip.
