Videos don't display but sound is heard, unless you keep moving the mouse pointer(Then it displays video. Web pages also freeze, you cannot scroll up/down unless the mouse pointer is being moved. All of this tends to happen when running on battery.

Not sure if anyone really cares anymore, but the IE hardware acceleration workaround helped some, but only on videos online. Videos played driectly from the PC like WMV videos in windows media player still had issues with freezing. If anyone is curious, I finally resolved the issue by switching to an Aero theme and then back to the original theme. The only thing I notice changing is the Windwos Basic Colors. Which shouldn't have been set that way anyway. I had an aero theme already, but the colors were still Basic. Making this change fix all issues. Don't even have to check the acceleration option in IE either.

Mine is doing the same issue. Tried several driver updates and nothing has fixed it. I have started trying Windows Updates, but am trying to pinpoint the exact one. Is yours still working now? Which windows update group do you think the fix came from? The September updates or the August ones? Working may way through the September ones with no luck so far...

Desperation!

 

All Windows Update install (Microsoft Windows 7 Enterprise (64-bit) @ 17. Sept. 2015.

 

All HP Update install (also the new BISO V1.09)  @ 17. Sept. 2015.

 

Screen freezing & Sound runs = without ACpower, Plugged ACpower all runs.

 

NOTE: If the display-port is plugged in = there is also NO freezing (ACpower is unplugged)

Yeah. I've still got the same issue. I've tried updates as well with no luck. Also noticed that plugging in a video cable seems to make it run fine as well.

I can solve the problem for me - with https://support.microsoft.com/kb/2528233

 

Let me fix it myself (as long as the HP does not provide, and the problem does not want to understand.)

How to enable or disable software rendering in Internet Explorer:

To disable hardware acceleration, follow these steps:
1) Click Start, and then click Internet Explorer.
2) Click the Tools icon in the upper-right corner, and then click Internet Options.
3) Click the Advanced tab, and then under Accelerated graphics, select the Use software rendering instead of GPU rendering check box.

4) Click Apply, and then click OK.
5) Close Internet Explorer and then restart it so that the change takes effect.
To enable hardware acceleration again, follow the previous steps, but in step 3, clear the Use software rendering instead of GPU rendering check box.
