Surface Pro 4 HUGE battery drain whilst off

Yesterday, after 48 hours without turning on the SP4, I checked how the battery went from 100% to 0%. Unfortunately, Microsoft doesn't seem to have anything to say about it. This has made my SP4 useless. The smallest desktop computer ever seen ... A Microsoft tease to its users ...

Same for me :(

Dear Edgar

It has been 10 days now but I am still waiting for a reply?

I've seen lots of references to removing the Intel Management Engine as a possible fix for this battery drain problem. Do you recommend that I try this and what is the best method for removal?

Regards

Russ

Dear Edd

I have now performed a clean install of the Windows 10 May 2019 release and latest surface drivers. This was a complete wipe and reinstall - not an in-place upgrade.

Unfortunately this has made no difference whatsoever to the battery drain issue - yet again 17% charge lost overnight, which is typical.

Sincerely

Russ

Dear Edd

Thanks for your response. Answers below :

May we know the current OS version and build of your Surface Pro 4?

Edition : Windows 10 Pro 64 bit

Version : 1903

Installed on : 31/08/2019

CPU : Intel Core m3 @0.90GHz

Skylake-U/Y 14nm Technology

RAM : 4.00GB Dual Channel DDR3 (14-17-17-40)

Motherboard : Microsoft Corporation Surface Pro 4 (U3E1)

BIOS Version : 108.2706.768

Date : 18/04/2019

How do you use your Surface Pro 4?

Mostly just web browsing and email (nothing unusual)

What application do you usually use?

Edge browser etc

I will try a clean re-install of Windows 10 Pro as per your suggestion.

Is there anything I should upgrade first e.g. BIOS firmware?

Can I also change the install language while I'm at it? This is a Spanish version of windows which I've changed to English but what is really annoying is it continually changes the keyboard back to the Spanish one (I don't know why) and there seems to be no way to stop this from happening e.g. it appears that the Spanish keyboard option cannot be removed.

Please advise whether there's anything else I should be aware of before proceeding with the re-install.

My surface pro 4 is currently losing around 20% charge overnight. This is a widely reported problem and I have tried all of the various suggested fixes - no improvement. 

MICROSOFT - WHEN ARE YOU GOING TO FIX THIS???

Hi

Thanks for reaching Microsoft Surface Community. We apologized for the inconvenience on this matter. We don't want you to have this kind of experience. Just to have this isolated and provided a right resolution, we do have some few questions and suggestions below.

May we know the current OS version and build of your Surface Pro 4?

To find out which version and build of Windows you're using, select Start > Settings  > System  > About , then look under Windows Specifications to find your operating system version and OS build number.

How do you use your Surface Pro 4?

What application do you usually use?

 Probably this is more on a hardware or a Software issue. You may consider trying the suggestions below and try each if that helps.

Suggestion #1:

1. Plug in your Surface. 
2. Select the search box in the taskbar, enter device manager, and in the search

results, select Device Manager. 

3. Select the arrow next to the Batteries category. 
4. Double-tap or double-click Microsoft ACPI-Compliant Control Method Battery,

select the Driver tab, and select Uninstall > OK. (Or you can right-click

Microsoft ACPI-Compliant Control Method Battery and select Uninstall.) 

5. Leave your Surface plugged in. 
6. After you remove the battery driver, install Surface and Windows updates. Go

to Settings, Updates, and check for updates manually and install any updates

that are available. 

7. Restart your Surface and test to see if anything has changed.

Suggestion #2:

Perform an In-place Upgrade with Windows 10. Ensure you are signed in or have administrator rights to do a repair install. Unplug all external peripherals except for the Mouse, Keyboard, and LAN cable before starting. Disable or uninstall any 3rd party Anti-Virus Program to prevent it from interfering with the upgrade. 

1. Select Download tool now, and select Run. You need to be an administrator to run this tool.
2. On theLicense terms page, if you accept the license terms, select Accept.
3. On the What do you want to do? page, select Upgrade this PC now, and then select Next.
4. After downloading and installing, the tool will walk you through how to set up Windows 10 on your PC. All Windows 10 editions are available when you select Windows 10,except for Enterprise edition.
5. When Windows 10 is ready to install, you’ll see a recap of what you’ve chosen, and what will be kept through the upgrade. Select Change what to keep to set whether you would like to Keep personal files and apps, or Keep personal files only, or choose to keep Nothingduring the upgrade.
6. Save and close any open apps and files you may be running, and when you’re ready, select Install.
7. It might take some time to install Windows 10, and your PC will restart a few times. Make sure you don’t turn off your PC.

Please let me know if this helps. Or if we have progress, looking forward on your response.

Regards,

Edd
