Are there any other hardware devices locked by Lenovo or can I upgrade the ram and the ssd freely? I have read on other posts that all devices that have a Lenovo part number must be replaced with Lenovo parts. I did buy an Intel 7260hmw ac and that's how I found out about the whitelist issues. I was planning on upgrading the rest as well but don't want to waste money if there will be issues. Also if there is whitelisting on all the other parts will the bios mod take care of them? Thanks
