TM2 Touch screen delay issue?

‎02-08-2010 09:57 AM

I am owner of new TM2 and have noticed on other forums that others have this same issue.  After not interacting with the screen via your finger for 10 seconds or longer, the 'touch aspect of the screen seems to go to sleep.  Then when you touch the screen next (after 10 + seconds of inactivity), it takes a second for the screen to 'wake up'.  After this wakeup, every su successive touch is instant, as long as it is within 10 seconds or so.

 

Any solutions/ideas?  I've tried almost every setting in control panel, and also many of the settings for the graphics card.  I even looked in the bios.  Spent 1.5 hours on the phone with HP support (basically walking me through everything I already did) and no luck.

 

It sounds like a non-issue, but if you desire to primarily interact with the screen via your finger, it becomes extremely annoying surprisingly fast. 

 

Other than that, its an awesome machine.  If I can't get this fixed, might wind up returning....

 

I also have noticed that none of the Tx2's I've played with, had this issue.  I can't find any TM2s in the stores yet to see.

  • Go to the device manager, expand the 'human interface devices' category 
  • Double click the first USB input device entry. 
  • In the USB input device Properties Windows, goto the power management tab, and uncheck 'Allow the computer to turn off this device to save power'.

That should do the trick!

This fixed the issue and my tm2 is now usable in touchscreen mode. If anyone at HP monitors these forums, this change should be included with the default build as the fix is obscure and the problem incredibly annoying. Also, HP tech support knows nothing of the issue which only makes it more frustrating to troubleshoot.
