S21e-20 Lenovo Upgrade to Windows 10 HOWTO
This is the method I used to upgrade my s21e-20 notebook. Note that you do NOT have to wait for the confirmation to use this method!

So I have a s21e-20 with 32 gbssd. Windows requirement says its gonna need at leat 20gb. I only have 11.6 out of 22 gb available. So can I still install win 10 and let it overwrite whats being used in me drive?

I was able to upgrade with just about the same amount of available space using the above method. The thumbdrive is critical due to the lack of space. I also did not keep any existing apps/settings just so that I could get through the OS upgrade with less isees.
It is not a simple run the upgrade and you are done scenario unforetunatly. You will need to manually install the required drivers. I am a senior engineer with 30+ years experience so shared what my method was to get the upgrade working.
Since it has been running for a few days now I am pleased with Windows 10. A couple of minor issues, like the screen dims instead of brightening when you slide the dimmer (odd bug for Lenovo to miss!) and I have had a couple of freeze on login issues.

Thanks for the tips on upgrading the S21e-20 to Windows 10.
Have two minor questions that will help my install:
1. When you run the Media Creation Tool and specify you want an upgrade copy to run on a different computer, it gives you different Win-10 64 bit choices. Which one is the most appropriate? I think it's most likely Window 10 Home but it could be WIndows 10 Pro (there are also other 64 bit choices but I don't think they are applicable). What worked for your install?
2. I've downloaded the Lenovo drivers on to a USB drive (there's also a Realtek SD card driver there now so I may not need the separate Realtek driver that's on their website). When installing the drivers, does this need to be done from the command prompt (aka MS-DOS) or is it functional from the new Win-10 installation? Not sure how functional the new Win-10 install is before the the Win-10 drivers since there are so many to load...

Here are your answers....
1. The Media Creation Tool does not give you options for architecture or version. The version is purely decided on the License key. Arcehtecture is 64bit since the Lenovo laptop is 64bit, and yes it is the Home edition from the factory.
2. The drivers all have windows installers and just need to be installed after the windows install is complete. I mention you needing an external mouse since the trackball is not recogized after the install. I used a standard Microsoft USB mouse I had lying around.
Hope this helps!

After this process, will it work to copy down the product key, and then do a fresh install, formatting the entire drive in order to recover all of the space, or does the S21e require the recovery partition to boot properly?
I recently ordered one and am waiting for it to arrive. In the mean time, I was wondering, does anyone know if the internal storage is soldered in place, or is it on a separate PCB, using a board to board interconnect?
Also for the card reader, does a micro SD card fully insert, or is it one of those half depth card slots?

The product key is in the bios so a full erase works just fine and you don't even have to mess with it. I did a complete format myself without a glitch. Not sure about upgrading the drive, which I too am interested in doing. I may take a look and see. But I can answer the SD card question; it sits recessed out of the way.

According to a mobile-edge.com review, the 2 gb ram is factory hard wired to the board and it also mentions the eMMC SSD is also not user upgradeable. http://www.mobil-edge.com/lenovo-s21e-11-6-inch-la
There is a Lenovo s21e hardware maintenance manual that does offer a rather detailed explanation on how to tear down the machine for repairs: https://support.lenovo.com/us/en/docs/UM101345
Basically it looks like it's possible to replace the keyboard or battery if needed, but other repairs would be quite a challenge. I've replaced the battery pack and memory cards on my MacBook Pro but to do memory card swap outs on the S21e would likely require rather delicate soldering (which would likely zap the warrantee and also risk zapping the laptop...). Still, I'm sure some enterprising hacker will find a way to successfully (and carefully) do it.
Think the S21e is a fantastic value for the money for a name brand small netbook that can run Win 8.1 or Win 10 (I upgraded mine to Win 10 using a USB flash drive with the new OS and a separate USB with the needed Win 10 drivers).

Just finished doing a ceann install of windows 10, and have all of the drivers installed, and everything seems to be working well, though I do have one unknown device.
Partition size is at 28.5GB
