Hello Folks & Dmitry,

Further to the previous patch, here is the current version (against
mainline) updated with the DMI info of another laptop model where this
fix had helped a user.

Can you please review it & give some feedback? If it looks good as it
is, then on behalf of all affected users (including yours truly), may
I request for it to be merged upstream (and possibly stable too)?

(If the patch gets spoiled by gmail, please ref to this bugzilla URL,
where this patch is there as a file attachment:

Thanks
