Here is the final 1683_x0t_Svet_Modified BIOS release for this notebook and it is rock solid. You can download it from my mediafire shared folder @ http://www.mediafire.com/?c2svnwgwn91fdh3
. I recently installed an OCZ Vertex 4 128GB SSD in my A5000-025US and it is absolutely flying! Unfortunately I get a consistent freeze with occasional GPU artifacts and then reboot after 5-10 minutes running my genuine Windows 8 PRO and it has something to do with a power saving feature of the Nvidia 8200M GPU driver. The only fix for it right now is to run "bcdedit /set disabledynamictick yes" at an administrative command prompt and reboot, I am hoping a future Nvidia GPU driver or another patch from Microshaft will fix this freeze. Windows 7 SP-1 runs flawlessly with the OCZ Vertex 4 128GB but Windows 8 PRO definitely runs faster overall then Windows 7. Has anyone else noticed this freeze/reboot issue with Windows 8 with their A5000-025US? This has been my favorite laptop and it is derfinitely built to last with no issues.
