The white TP variant that was shortly for sale in Europe has 64GB. There were also a few TP Go prototypes with 64GB. So I think it should work to replace the 32GB with 64GB. About the 1GB internal memory I'm not sure, but it might be possible to upgrade it to 2GB.
I actually have two units that no longer power up. My regular unit is currently on my Touchstone and is also connected to a USB port on my PC. It seems to me that some apps will not allow the TP to shut down normally. I think this may be the case since on two occasions, this happened after running newly downloaded apps.
I have had no luck so far with the Ubuntu solutions I found while looking everywhere in a panic.
I do know that the batteries of both units displayed odd ( to me) behavior while I attempted to charge them externally. The batteries were removed and connected to an external source. They were left to charge for several hours at different current levels. (I have read scary stories about charging LIPO batteries)About 3 seconds after they were removed from the source their output voltage fell to zero. I have ordered replacement batteries for both units, mainly because I don't have a better idea.
I will install them and see what happens. In the meantime, I am still curious as can be about the switch I mentioned and the connection of the BGA memory chip. I bought the second TP broken and had it working for a while after externally charging the battery and I would use this one as a test bed for a memory modification if I thought there was a reasonable chance of SUCCESS instead of suck-age. I thought I might be able to beat the 32 Gig memory limit imposed by HP on the TP.
I will keep looking, and thanks again,
