847/5000 Hello, the post is old but I hope someone find this info useful, since these notebooks are currently getting very cheap. I have the same notebook Lenovo G400 20235, [but it came with a core i3-3110m, integrated intel HD4000 and intel WiFi card], I have successfully tried an i7-3632QM and a i7-3520M, both work OK. I have also tested it with Hyperx Impact Black memories (Kingston) DDR3L 1600 16Gb kit (2x8Gb) working OK. A friend also had the same Lenovo G400 but his came with a Celeron installed, that notebook did not accept the i7, not even the i3 that I uninstalled, also did not accept the 16Gb of RAM (only accepted 8Gb, either a single module of 8Gb or two of 4Gb). I hope this helps someone.

Hello, I would like you to help me with my old Lenovo G400 laptop [intel only with HD4000 video], my WiFi card stopped working (intel too) and I got a broadcom that supposedly is compatible with G400, but the machine did not accept it. I have another two notebook exactly the same, (I got them for less than 50usd each and I gave as present to my brothers to use in school), does the same BIOS mod work for all or should one be made for each in case they failed the Wifi card too? I thank you in advance for the help. I already sent you the results file through PM.
