还有就是BIOS lock了,不是你一换下去就可以用的,以下是whitelist,就是所谓只支持的
y580 bios rom file and managed to get following wireless cards PCI id's from it's whitelist: (Vendor ID) - (Device ID) - (Subsystem ID) 8086 - 0891 - 8086 4222 8086 - 0886 - 8086 1513 14E4 - 4727 - 14E4 051B 14E4 - 4727 - 14E4 0587 14E4 - 4358 - 14E4 0544 168C - 002E - 17AA 31A4 168C - 002B - 17AA 30A1 168C - 002B - 17AA 31A1 168C - 0032 - 17AA 3118 168C - 0032 - 17AA 3218 168C - 0034 - 17AA 3214 As you can see, list of wlan cards is really small. Of these, 8086 are by intel, 14e4 by broadcom and 168c by atheros. You can search for wlan cards using these IDs. Warning! BIOS will accept WLAN card if and only if it's IDs EXACTLY match one of the above, all the others, even having the same model name / being technically identical, will not pass wl check.
所以用USB的买好点的就算了吧参考网:https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Dual-band-wifi-card-supported-by-Y580/td-p/853565
