Hi, Here is a link to the service manual for Lenovo Yoga 300 11IBR and 11IBY. https://download.lenovo.com/consumer/mob… It is handy in that it shows how to disassemble the device. It also gives the part numbers of the individual FRU’s (components). You say, that in your device the storage is permanently mounted on the systemboard. From the service manual it appears that the storage types are dependent on what systemboard is installed (see p.61-62 for all the systemboard types). To my mind the easiest way to overcome your problem is to buy the largest capacity SD/SDHC/SDXC/MMC card e.g. 64GB,128GB etc, that you can afford and insert it in the card reader slot and use that as a second “drive”. You could try replacing the systemboard with one that uses a different storage method, using the part numbers from the manual (p.61-62) to find a suitable replacement type, but this may involve more than just a board change as there may be power supply considerations and other factors coming into play, I don’t know. Hopefully this is of some help.
Hi Buy a ssd on Aliexpress and a sata cable adapter (specially for this pc). Open the bottom and put it inside the dedicated bay. Near to the upper left corner of the battery, you’ll see a sata connector on the board. It’s labelled. No problem. My idea is run it under Ubuntu instead of W10 crap. Guys on forums say it’s okay… we’ll try. Good luck.
