I thought that I wouldn't be able to replace the hard drive in an Acer Spin 1 SP111-31N-C4UG but when I went to Crucial.com to look for upgrades, it had several SSDs listed for this model. I also double checked a laptop that I knew I couldn't upgrade and it only offered RAM options with no SSD. Is this tool from Crucial a reasonable way to judge if the hard drive is able to be replaced? Does anyone know of other ways of checking other than ordering it and seeing once they get it? Thanks
