this post is obsolete please refer to my newer oneHi, first of all thanks for your interest in my blog but most of all thanks for your interest in updating your old VAIO to Windows 10. After all I think this is still a wonderful notebook and even if it's a bit slow it's still useful for many purposes.
In the weekend I've tried Windows 10 on an external USB Drive (not ready to format the internal HDD yet) and I've had this problems:
- the graphic card as you found out don't work (neither the Intel or the nVidia one) (more details follow). Basically I'm stuck at 1024x768 with a standard card driver.
- the brightness key Fn+F5/F6 don't work (maybe because of the problems with the cards)
- Fn+F7 doesn't work (same as above)
- audio and card readers are ok, all the other hardware seems working properly.
In the device manager the graphic cards are reported with an exclamation mark and in the properties I've found this message:
This device cannot find enough free resources that it can use. (Code 12)
If you want to use this device, you will need to disable one of the other devices on this system.
I've googled a bit but didn't find anything which suggested me a solution.
I've looked on the Intel website and it seems that Intel doesn't care to provide an updated driver for such an old CPU but we are still in preview, hopefully they will provide a decent driver in the final version (hopefully yeah...).
Obviously Sony won't provide any driver so I don't think there will be a solution which will make the nVidia card work properly but having the right resolution and brightness working will be nice at least for one of the cards.
If you have any ideas on the error reported feel free to comment this post or write directly at my e-mail.
