Check for a BIOS upgrade for your machine.

> Check for a BIOS upgrade for your machine.

rhere is no bios upgrade for my laptop.
this issue whas discovered only with xorg-x11 7.1 , when i use xorg-x11 7.0
when i was downgrade my software to xorg-x11 7.0 dpms works fine and lcd 
blacklight turns off - my friends on another laptops from diferend producers 
have same problem... so maybe this is a bug in new i810 driver

Nothing has changed in the driver with regard to DPMS for quite some time.

Can you upload a log file ?
