Try to clean your Surface clean as indicated here. IF you believe that their might be phantom touches happening, I'll suggest contacting support.

Hi all,
Lately I've been noticing a large battery drain (at least by my standards) of ~1-2% per hour during connected standby. Based on what's advertised (7-10 days idle) I'm getting ~4 days at best? I ran the sleep study, battery report and energy report and came up with interesting results. I've also calibrated the battery and have no current pending updates. Any ideas as to why the large battery drain during standby?
Also sorry in advance for the long post. I'm not sure how to post the full reports on this forum.

2014-05-16T05:01:59+00:00 Yesterday I had nine updates, installed and rebooted.
Last night I shut my device down around 11:00pm, and I opened it up this morning around 7:30am. At 11:00pm I had about 73% battery, when I woke it up in the AM I noticed I had 33%. So 40% over 8-9 hours with the cover closed. I did not get any of the display errors over night.
In the event viewer I see the device sometimes wakes up due to user input. I'm not sure if this is due to a Bluetooth mouse I did not shut off or something else. Sometimes when it wakes up due to user input there is a BITS event immediately after this.
In my next test I will ensure my Bluetooth mouse is off.

2014-05-15T00:36:54+00:00 Update, I refreshed my surface today without the type cover attached and installed all the updates. Battery drain is still 1-2% per hour with display error popping up. I haven't run any other power or battery test yet because I only refreshed today. In a few days I'll run the tests to see if I notice any differences.
Scottfaber, I did take a look at the display error. Prior to the refresh, the display error would pop up frequently in almost exactly 15min intervals as you stated. After the refresh, it's popping up every 30mins or so. No idea what's going on here.
v0lum3, I did adjust this setting prior to the refresh and I didn't notice any difference. I'll try it again and update with any changes in a few days.

2014-05-14T17:12:02+00:00 I have just send mine in for replacement, didn't want to wait.. and just as I had UPS pick it up, a techsupport just called me with a possible solution that you guys might find helpful.. since I wont be able to test it!
So here you go.. this should remove the Unregistered Device SE, according to the techsuppoerter:
Step 2: In the search box, enter command prompt. Step 3: Touch and hold (or right-click) Command Promptto bring up the context menu. Tap or click Run as administrator. Step 4: On the User Account Controldialog box, tap or click Yes. Step 5: At the Administrator: Command Prompt, enter the following: <br><br> powercfg -setdcvalueindex SCHEME_CURRENT 19cbb8fa-5279-450e-9fac-8a3d5fedd0c1 12bbebe6-58d6-4636-95bb-3217ef867c1a 3 Step 6: Then enter <br><br> powercfg -setactive scheme_current -

I noticed on my device that when I'm in standby my battery also burns a percent or so an hour. I reviewed my event logs/system and noticed that the graphics driver is crashing every 15 minutes. If you look at your 4001 error can you relate them to when you are in standby mode, is it almost exactly every 15 minutes?
