A quick discovery when using the volume control and On Screen Display does not work.
I had this problem on my Acer Netbook Aspire One. After hooking it up to an external monitor, I found that the OSD (On Screen Display) did not work any longer when changing the volume up or down. This lasted a couple of months, the Acer Support site had no real answers other than to do one of 2 things. Make sure “Launch Manager” was using the latest driver and was actually activated. Anytime you re-start your machine it should start LM (launch manager) by default; I did download the latest driver and still no joy. The other Acer Support suggestion was to “”system will need to be restored back to factory defaults using the eRecovery software or Recovery media”, well, I didn’t need the OSD that bad.
After playing around on the Acer one day, I discovered somehow “Color Quality” setting was at 16bit instead of 32bit. I went ahead and changed that to 32bit, and like magic the Volume OSD started working again. I tested this several times and yes, this was the cause for me…
Good luck… Rick
Just in case anyone else runs into this problem, Launch Manager (dritek) is responsible for these sorts of OSD’s
try hitting start, in the search type in “launch manager” and start it
wait a minute and if your normal OSD’s return that was the cause
go to start
type
msconfig
then hit enter and ensure that launch manager is enabled in the startup tab
I have used this trick twice now. It has worked both times! thanks very much for the help!
I inadvertently disabled the on screen display when using the Norton startup manager to disable a lot of extra junk that was using up too much of the processor memory. On the Acer OAD257 netbook the program for onscreen display is LManager.
Renabling it in Norton startup restored the volume, caps lock, num lock onscreen display.
This worked for my Acer Aspire 722 thanks man.
I have the same problem, in that my volume display, num lock display and caps lock display do not pop up when adjusted, as they used to until yesterday or so. I cant find the problem.
Lauch Manager is indeed enabled under Start Up in msconfig, still to avail. Confirm with me that the Launch Manager is off Dritek Systems? And not of Acer? Fortunately, i too use Norton, but how do i get into Norton Startup to restore the functions? Thanks .
