Hi
Several people including myself have encountered serious problems with the Windows 8.1 Preview video driver for the Lenovo Thinkpad Tablet 2. This is an Atom-based tablet, version 9.14.3.1160.
The problem is that after the tablet has been in connected standby for a while (somewhere between a few minutes and half an hour.) it will not wake and it's necessary to force a shutdown & restart the tablet.
It is easy to show that this is due to the video driver. When I install the Windows 8 driver available from Lenovo (version 9.14.3.1099) the problem does not occur.
A common way to reproduce the problem is to use the folio cover for the tablet. When the cover is closed, the tablet goes into standby. When the cover is opened, the tablet does not come out of standby but remains inert.
Please investigate this problem and release an updated driver.
Thanks
