After last BIOS update to ver. F.14 I tested another a micro SD card, GOOD RAM microSDHC 32GB Class 10 UHS-I and there is the same problem with long time system loading (before appears HP logo), like on aforementioned my Samsung 64GB card).
HP, wake up and fix finally this bug!
Colleagues on the forum, please tell me, which cards (producer, type) you use and works correctly (fast loading the system)? I'm interested in cards with capacities 32/64 or 128 GB.
I bought a microSD card from another producer, Kingston type SDCA3/64GB. The card is very fast (read and write) and works perfectly with fast loading the system and without any disconnections and write problems. I recommend this card!
Thanks for your comment, great to hear you had success with Kingston type SDCA3/64GB! How have you been testing it? It would be nice to understand the kind of performance you're getting.
Which BIOS version are you using, the F.14 or another?
May I ask where can I find this BIOS update F14A ? This site gives me F07 as the latest bios update. Why? Does that mean F14 update will break my computer because it's perhaps not compatible with my x2 210?
There MANY different machines under the X2 brand that look identical and there -were- at least two variants of the motherboard when we were discussing this last year, I don't know if HP have introduced anymore since.
Each motherboard had it's own BIOS firmware.
Use the HP Support Assistant to find out the latest BIOS for your mainboard. F14A was the latest for my machines in September, I've not checked since because this BIOS is working fine for me.
