please help me with touchscreen troubleshooting.

Hi. I posted about this in the dell support forums. But no one answered. So while searching for an appropriate place to post it, I found this site.

I got an inspiron 11 4 days ago. I started noticing that sometimes the touchscreen wouldn't work correctly. Sometimes It takes a few taps to register a touch, other times it just quits working for a few seconds. This makes it hard to do anything, and makes it completely impossible to play any touchscreen games.

After a couple days, I finally figured out that It was on battery power that I had the problems. When plugged in the touchscreen works perfectly.

I have downloaded all the dell updates, and windows updates. I've also tried to turn off all the battery saving options I could find. Under power options advanced screen I changed every option to the same for plugged in and on battery. I turned off the option for dells power saving features. In device manager I took away windows ability to put usb hub asleep. There Is probably more I'm forgetting. Basically everywhere I seen a difference between battery and plugged in, i changed.

It passes all the hardware checks, both through dell software, and on the bootup hardware check.

So, Is there a setting I might be missing, or do you think this is a hardware problem?

Please help. I use this in tablet mode 90% of the time. And returning it to laptop mode to use touchpad/keyboard, and not being able to play games on battery, just isn't acceptable.
