I have the following issue with my t460p after I've updated the video driver to version 188.8.131.5216 (r07i616w):
Pausing a video (i.e. youtube in a browser) and continuing after some time leads to a BSOD. This happens reproducible if screen has been turned off by power manager, while video has been paused.
steps to reproduce:
1. in power manager set the time to switch off screen to 1 minute
2. start playing a youtube video in a browser (in my case google chrome)
3. pause video
4. wait until screen has been turned off
5. continue playing video
more informations to BSOD:
OS Version: 6_1_7601
Service Pack: 1_0
this does not happen with video driver 184.108.40.20652 (r07i613w).
BIOS is version 2.05. (latest from the lenovo website)
Newer drivers downloaded from Intel ( 220.127.116.1124 and 18.104.22.16863) seem to have the same problem.
Sometimes system crashes just by using the intel graphics options panel by selecting video. The picture of the child should be displayed, instead the system crashes.
As newer Intel drivers have the same issue, it looks to me that maybe something different coud be triggering this crashes. Maybe BIOS? What is the recommended BIOS version to use in a t460p (no Optimus)?
Can I safely downgrade the BIOS version to 2.03 or 2.04?
