You can replace one of two RAM modules. The other one is soldered on the Motherboard. mSATA is upgradeable also very easily.
Before you replace the RAM or SSD you have to Switch off the notebook by stiching a paper Clip in the notch of the battery . To restart the Notebook afterwards you have to plug in mains power like you did when you switched it on the first time.
Check the BIOS and Switch off "secure Boot" when you replaced the SSD. Otherwise the System fails to start maybe .
Any questions?
positiv:
+the default 6 GB RAM and a fast Samsung SSD with 256 GB (in the S04) are enough for every Situation today. No normal game or application would benefite from an upgrade a the moment.
negativ:
-the S03 with only 128 GB Samsung SSD has not so much free space as a the recovery partition needs 22GB and additional installed Software cuts even more GB. You should move the recovery Partition to an external harddrive and uninstall all the Software you do not need. Samsung installed a Programm called Recovery which makes this process easy. I'll will Show it in an other Video.
