...they knew the drivers needed for that model to work on w10 aren't available yet, but may in future.
Sony advised not to upgrade my Sony Vaio model VPCSA (AMD + Intel Graphics). I am disappointed to see the advice. My Vaio has Intel ® core™ i7-2640 CPU @2.80Ghz, RAM 8.00 GB, AMD Radeon 6600M and 6700M series and Intel ® HD Graphics 3000. I do not like to end its life with Windows 7.
I ignored the advice and upgraded. First time it has problem of Windows icon left bottom corner was not function. “Go back to Windows 7” restored the Windows 7 without any problems.
After a few days second time I tried again this time it worked but finger print scanner was not working the application crashed. And another problem was the Graphics Stamina and Speed switch was also not working. I update the Graphics cards drivers and Authentic Truesuit drivers but no solution.
Third times I did clean install this time, there were so many problems of drivers such as Biometric Devices AuthenTec Inc AES1660, Modems Huawei Govi 3000 HS-USB Modem, Network adapters and Ports (COM & LPT). I could not find the drivers on the Internet and their websites I found some but not helpful.
I restored the Windows 7 again and 4th time I upgraded to Windows 10 Pro. This time everything worked smoothly except the function of the Graphics Stamina and Speed switch.
During the upgrade the graphics Stamina and Speed switch was in Stamina Mode. After I upgraded I installed the AMD’s Graphics Cards Auto Detect and found no AMD graphics card. I checked the Device Manager – Display adapters there was only Intel ® HD Graphics 3000 then I switched from Stamina to Speed mode and the AMD Radeon 6600M and 6700M Series appeared. The Auto Detect found the driver and installed. I think the switch is still working but there is no notice of Graphics status (Stamina or Speed) like in Windows 7.
Sony website has this information regarding this matter:
“VPCSA/VPCSB/VPCSC/VPCSD/VPCSE Series
• Systems with switchable graphics that have both AMD and Intel graphics cards will experience BSOD (Blue Screen of Death).”
I do not have this problem.
I checked the Display properties, it is Intel ® HD Graphics 3000.
I cannot confirmed these two graphics cards are functioned like before (Windows 7) or it is only one graphics card working.
Some information of both graphics cards:
AMD Radeon 6600M and 6700M Series Properties – Events – Timestamp xx/xx/yyyy hh:m:s Description – Device migrated, Driver service added (amdkmdap), Driver service added (amdkmdag), Driver service added (AMD External Events Utility..)
Intel ® HD Craphics 3000 Properties – Events – Timestamp – Device migrated, Driver service added (igfx), Driver service added (cphs)
I have no idea above these information.
I do not know Sony is going to abandon all these Viao models or they are going to provide us some solution of this problem. I do not think it is a serious problem but Sony should do something about this problem.
Thanks
