The 8GB RAM (CMSO8GX3M1A1333C9) arrived and a WiFi/Blutetooth Dual card (BCM94313HMGB) . All working fine with Windows 11 22000.132. I took the device completely apart, cleaned it, reseated all cables. Added a new CMOS battery, new thermal paste added. While youtube ran "ok" on windows 7 and windows 8.1, the videos started to lag again with Windows 10/11. Yes it is annoying but ok. It is still a bit slow, but a decent typewriter and surfmachine. The mainboard (mbsft02002 or "4619 akbol03") has 2x JMINI connectors. Its for Mini-PCIe cards. But only the JMINI 1 connector makes windows detect the card. JMINI 2 seems to be...dead ? Or just not present, just like the non soldered RAM 2 slot ? Any chance to...make it become...alive again ?
