Note: Install Windows 8 to Vaio P at your own risk.
I’ve been using Vaio P with preinstalled Vista, and later upgraded to Windows 7. I’ve then upgraded from 7 to Windows 8 Pro with keeping all apps and data. Upgrading to Windows 8 was easy, and completed without any problem, but speed was so slow.
Model I use is VGN-P91S custom model, with Atom Z550 2.0GHz cpu, 2GB RAM, 64GB SSD, which is far better spec than Viliv N5 or Willcom D4, but runs slower.
I understand P series have high resolution LCD which costs CPU performance, but still, this thing is too slow to use. After uninstalling all VAIO related preinstalled software, it started to work better. I guess preinstalled software is eating resources.
Well, since SSD space was also running low, I decided to clean install Windows 8 to Vaio. Clean install is simple, just use 32bit version of Windows 8, set setup media to USB DVD drive, and boot. Remove all existing partition (except recovery area, if you want to keep it), and install, done.
After install, about 2 devices remain unknown, but 1 will be gone by auto detecting device driver. WiFi and Bluetooth works by default, and you could use most of the functions at this time.
Most of the function works, but making last few percent to work perfectly is a hard part. There are many preinstalled VAIO software, but I focused to make following functions to work.
- Install VGA Driver
- Scroll using stick pointer
- Battery care function (limit charging to 80%)
- Adjust volume / brightness using Fn key
Thanks to following sites, which helped installation / configuration)
First, prepare all software and drivers you need. Followings are software / drivers I’ve used (Some may be in japanese).
*EMGD 3228Driver also works (might work better)
Followings are from ftp://ftp.vaio-link.com/pub/Vaio/ORIGINAL/
– Pointing driver
– Setting Utility
– Vaio Event Service (Fn Keys)
VAIO Event Service 5.1 – 126.96.36.19900.ZIP
– VAIO Power Management
– VAIO Control Center
For each driver / software, run EXE or run setup.exe after extracting ZIP file. Follow wizard to install. Note you need to install Control Center as a last thing, and Video driver and Power Management needs little trick to install.
For Video driver and Power Management, simply running will show up unsupported OS error. Right click setup.exe, open property, and go to compatibility tab. Check “Run this program in compatibility mode” and select Windows 7. Then, run setup.exe to install.
After installing all drivers and software, you can configure Vaio devices, and use Fn key to adjust volume and brightness.
Since P series have resolution of 1600×768, store apps work without problem. This is still good device in Windows 8 age. Office 2013 also working without problem. You can use simulator (included in VS2012) to run store app in Window mode, but this seems too much for P to handle.
From user’s report, there’s sound driver Realtek R2.70 you can download from Realtek homepage, which enables noise canceling.
