Question for 1500 and 1520 owners

For some reason, the users on this forum don't seem to have the problem of keyboard lag which is a big issue on the offical Dell forum.

(ref: http://www.dellcommunity.com/supportforums/board/message?board.id=insp_general&thread.id=257203&view=by_date_ascending&page=1 )

We've found that the keyboard lag can be eliminated by preventing the PCMservice.exe or NVHotkeys TSRs from loading at bootup. The Dell techs haven't figured it out yet and are giving useless advice... and they are still shipping notebooks with this bug.

What I'd like to know is, if your 1500 or 1520 does not suffer from keyboard lag, what is different about your notebook?

Does your notebook load PCMservices and NVHotKeys?
Is Dell MediaDirect installed? Which version?

The latest post on the Dell forum suggest that it is caused by a buggy version of Dell Media Direct.

 

How would you be able to tell the lag. I have had the keyboard cut out on me in game. usually when turning left actually in nfs prostreet is when it cuts out the most, i attempt to turn and it doesnt react, granted i have N, Space, Up, Left and B pushed. Once I let go of left key it goes sometimes all keys

 

I have never noticed any lag when typing or gaming (or any other time I use the keyboard). I do not have MediaDirect installed and do not load NVHotKeys or PCMservices at startup.

 

No problems here.

PCMservice loads

NVHotkeys do not load.

Dell Media Direct Version 3.5.3624

There is a patch for MediaDirect as well as update on Bios that addresses MediaDirect.

 

The way it should work, is as you type, let's say in notepad or as a reply in this forum, the keys you hit instantly (from the human prospective) appear on the screen. If your computer has typing lag, the keys you hit are buffered, but display on the screen anywhere from a fraction of a second to more than a second later. If you try to hold down the backspace key to delete text, the backspacing is also buffered, and you don't have a chance of releasing it at the right moment, it will just continue to backspace through the display until the backspaces in the buffer are depleted.

It’s interesting that the two of you who replied that you don’t have the problem, don’t have the services loaded, that we’ve been removing as a work around.

 

Well for me PCMservice loads

NVHotkeys do not load.

no lag typing but brief pause with backspace
