Device Encryption is a new facility in Windows 8.1. It applies only to small devices that meet certain requirements. It can be a great help bit also a pain depending how you use your device.
I have been playing around with it for a while and documented my findings. I have uploaded my report to my OneDrive. If you left click on the tile in OneDrive, you can read it in your browser. If you right click on the tile in OneDrive, you can download the PDF.
Another well explained operation,your tutorials always explains the for's and against, making it easy for those following to decide whether to operate or leave well alone !!! (The latter applies in my case CHOL:) but I do enjoy trying to improve my old grey matter.
Thanks guys. I had to learn that the hard way. I bought this little laptop and next I see the device is encrypted without asking me. There was nothing I could do with it because the BIOS was also locked. But piece by piece I found the information and finally decrypted the device.
Now it is a normal UEFI laptop which runs W8.1 and Mint Mate under VMware Player. Because of the cramped disk space (only 32GB and only 20GB for C, I put Mint on a USB stick and run it from USB2 which is not the fastest but once booted it is OK. One cannot expec too much from a laptop that I paid only $99. Now they sell it for $149.
