My Latitude D620 stuck at bios post screen when i upgrade wifi ot Intel N-6230. Is there any way to fix this and use my new wifi card?
Without any WLAN card, or with old one boot and work correctly. I cant find option to disable it from bios, there is only hardware button to turn it off and on.
The WLAN card is OK, I test it on other laptop. I find a way to start it on my but is very strange: Boot up laptop and wait to load windows without any WLAN. While laptop work, I plug in WLAN (N-6230) and windows find new BT device only. Restart laptop and everything works fine to next shutdown. Then... old story, stuck at bios post.
