Hi LattePanda,

I get zero volts across both of those points (15v and 9v). I tried with both 12v power and the LP USB-C Power adapter.
Any ideas? - You Reply:

Hi msrego, I'm reading 306 ohms across that capacitor.
From the voltage reading you gave, it is very probable you have a short circuit somewhere in the board, most probably on the 5V rail (due to the 0V readings).
Check the thread I opened and see if the 5V rail is shorted by measuring the resistance across the capacitor I circled in the photo. - You Reply: Thanks @Agree_dk, I managed to use a windows 10 Professional ISO image to boot my LPA and install a new copy of Windows on the original eMMC (preserving the copy of the old Windows clone on the NVMe). Interestingly this used the cloned UEFI partition on the NVMe disk even though it booted from the new Windows NVMe disk partition. I can confirm that the new install was automatically licensed too.
I then used a trial version of EasyUEFI to re-programme the UEFI partition to boot from the cloned Windows image on the NVMe partition to access the Windows version with all my programs and files.
I've now reformatted the eMMC disk as an additional disk.
One thing I did notice is that as the Windows updates come in, many of the drivers aren't available. I'm currently without WIFI, Bluetooth or Serial. It's not currently an issue for me as I'm using Gigabit Ethernet, but an updated resource kit for the LTA would be nice now.
