Battery Drains While Shutdown

I have the entire thread archived offline as well. My emails to an internal

contact on this issue have had no replies. I'm a volunteer, I have no magical

powers to get Microsoft to take action or even respond.

>It would not surprise me to see this entire thread deleted after a few days - which is why I have archived the entire thing.

I understand that you're a volunteer and have no "powers".  It's very disappointing that even your internal emails are going unanswered.  It definitely feels like an official, but unspoken, policy decision has been made.  My next computer will NOT be a Surface, unfortunately, but it would be nice to see Microsoft address or even acknowledge the issue.  That's why I'm writing to the magazines, the BBB and Consumer Reports.  Maybe the publicity will make them stand up and take notice.  

I think others on this forum should do the same.

*"*Sounds like microsoft wants the users to figure out the problem"

I disagree.  I don't think that Microsoft really cares what the users do.  I think they know that this is a manufacturing defect for which the only solution is a replacement, but they don't want to acknowledge that because it will be too expensive. 

Clearly, after the hundreds of unanswered posts here, Microsoft is just avoiding the issue.  I have given up trying to get their attention this way, and have begun writing letters to the editors of PC Magazine and other entities that rate companies and computers; maybe in the face of a critical article or a request for answers/interviews they will be forced to address the issue.  I am also writing to Consumer Reports and to the BBB, and to public relations people at Microsoft. 

They can ignore a thread like this, they can ignore a few hundred users - but they don't want the bad publicity.  Maybe. 

From their point of view, it's easier to close their eyes to this problem and hope it goes away rather than have to replace thousands of batteries.  The bottom line is that they are in the software business, and if another company can sell better tablet computers with better support, they will still make money from putting software on them.

Your battery, back in September, shows 360 battery cycles.  One site suggests a battery will normally last for 300-500 cycles.  So you are in that zone with your battery.

There is another thread where a battery is draining while in hibernation about the amount a Modern Standby system will drain while in Modern Standby.  It is not supposed to drain in hibernation either, but it is.. and the battery only had 56 cycles.

You may have a battery which is failing and along with unexpected drains, will show an accelerated drain.  The high number of cycles on the battery may exclude you from being considered for a warranty replacement.

I would still suggest you put your system back to the factory configuration and let it work as designed.  It may still drain, but might not drain as much.

I am currently looking at the Surface Pro 6.  Before I purchase, I want to know how much it will cost to replace a battery in an $1800 unit.  I think the answer to the question may keep me from going down that road.

I've the same problem with Surface Pro 4. I shutdown it at 100% battery, also while pressing SHIFT on keyboard, but still drain battery... and when I power on I need to plug the power cable because the battery is at 0%.

I think that Microsoft need a smarter way to manage this... I don't want download email or updates when is powered off.
