Surface Pro 3 LGC Battery Degradation

I took my Surface into my local Microsoft Store a few hours ago and let their technicians work on it.  They spent 3 or 4 hours installing various versions of Windows, but could not fix the issue.  Since they couldn't fix it by reinstalling Windows, their response is that it must be a hardware problem.  Sounds like a cop-out to me.  And yes, the only option they are giving me is to replace the Surface with another unit for $450.

This is for sure a huge issue. I see thousands having this problem and all seam to come from a "microsoft firmware update" killing a otherwise working tablet. I see the only way to get it fixed is to send it into microsoft and they will charge us $450 usd and "fix" the problem. I am not happy and hope they release a fix for a problem most think they created. I see a HUGE class action coming soon and hate to cause problems for a company like you I have defended thousands of times to friends who talk bad about them.

Long time Microsoft fan here (owner of countless Windows desktops and laptops, Kin phone, Lumia 928, Xbox, and Surface).

Yesterday, my Surface Pro 3 was working fine (besides the battery degradation).  I decided to go ahead and spend a couple hours getting all the latest updates as well as updating to Windows 10 Anniversary Update.  Before the updates, my Surface was working perfectly on battery.  As it was updating, I plugged in the charger to ensure it didn't die.  After getting all the latest updates, I noticed that Windows said my battery was at 65% and "Not charging".  I thought that was odd and fiddled with the charging cable (the light was on).  When I disconnected the cable, my Surface immediately shut off.

I then spent the next few hours trying to do multiple restarts, uninstall the battery driver, and finally Reset using the latest Windows 10 image I could download for the Surface.  Nothing has fixed this problem.  I believe one of the firmware updates has essentially killed my tablet.  It looks like I'm not alone.

My fiance is sitting on the couch with a smug grin on her face as she uses her Apple iPad.  I've defended Microsoft and their products a number of times, but if this issue doesn't get resolved, I'm going to seriously consider switching sides.

I was able to get the battery driver plugged in not charging to glitch today. I have for weeks not been able to use the surface pro 3 with out being plugged in as it would shut off after you unplugged it. I have tried all the updates and the suggested fixes but none have ever worked. After uninstalling the driver for the battery and restarting it it would always stay the same.... 26 percent battery and plugged in not charging. yesterday I did the uninstall driver and clicked the delete the driver box and restarted the surface. well upon boot the battery showed 100 percent charged for about 30 seconds and then reverted back to 25 percent and not charging. I have not been able to reproduce this glitch in a few days.. I am guessing there is an issue with the installer and driver combo and am now back to where I was before. I wish I could just revert the firmware back to previous version but believe this is not able to be done. Go figure just passed the warranty date and it is now just desk art. I hope a cure can be found soon.

Thank you for the prompt reply Barb. 

I was under the impression that restore was a complete wipe to the factory image (win8). My apologies for confusing the situation. I will do the win10 this evening from the link you provided.

And again thank you for helping with this.
