I'm starting a new thread because searching for this in the other (long) thread is impossible in this forum.

I have an SVF15N1C5E. Currently running windows 8 with bios update BIOS Update - R0230DD. After 1 to 10 minutes of use the touchscreen becomes inactive and i have to use the touchpad.

The current advice that i can find is to make the bios update (above). But that didnt work and i can't find anything else. So for me its back to putting it in 'sleep' mode for a minute then waking it up.

Does anyone else have a fix?

Thanks guys
