On the hp 11 g5 chromebook it comes with a 16gb emmc or ssd. Can you upgrade this with a seperate bought emmc or ssd.
I Believe you can put an SD card in the side to expand storage. But I don’t know the answer about the internal upgrade. I’ve opened up a chromebook before and it seems the storage is soldered to the motherboard.
buy another motherboard with a larger capacity chip. you can do a small upgrade depending if you have a 16 gb you can get a 32 gb hd also if you have 2gb memory you can get 4gb memory. look into it get the service guide . download.
I think you could as the Wireless chip is in the place an SSD would go. I am not 100% sure that you can, but you can try. Also, if you manage to do it, you risk your Internet.
