I'd like to chime in as an ACER laptop user that I have the exact same problems. So I very much support the position of users like Bill945 that this is not a Dell problem. Now of course, moderators, I understand perfectly about OEMs being strictly speaking exclusively responsible for such problems. But it's like saying the OEMs are strictly responsible for picking Windows instead of over, say, a Linux build. As Microsoft representatives do you really want us to conclude that it's the fault of Dell or Acer that they choose Microsoft?
The point about whether the OEMs are responsible are therefore irrelevant here. What we want to hear that is at least something like "The devs in our company are aware of the problem and will work on improving things in the future", or that "They will work with the OEMs to improve user experience." If you guys the moderators here are not allowed to say such things or feed user inputs here to the devs in some way, I sincerely suggest you start interviewing for a better job, if I may be a little blunt.
