A:Answer Thanks... some of my findings, 2 of the screws (Philips) are hidden under the back rubber feet. The others are T4 *, short on edges and long along rear. I've done the upgrade from 512MB to 2TB, however throughput with gen4 (Samsung 980 Pro) SSD was only 3300-3400, so it must be a gen 3 limitation. The machine ships with (Win 11) bitlocker enabled - disable before cloning, then re-enable after upgrade complete. The Samsung 970 Evo Plus (gen3) I ended up using was 7-10% faster than the stock SK hynix (reads close, writes now faster).
Thanks for your reply, too bad memory can't be upgraded, this is a fantastic machine (20 cpu cores), superb screen, and with MPP2.0 pen great sensitivity.
