Laptop display white/black list ?

[tomm]

Hi bios-mods community.

Recently i've got my Dell M301Z 13'3 slim display crasched.
To fix the issue I've tried to connect different models of different manufacturers. Mostly they worked fine, yet all of them present the same behaviour. When turning the laptop on (during P.O.S.T and boot) and turning off (shortly before shutdown) system buzzer plays that irritating beep sound.

It looks to me like white/black list. Isn't it? Have anyone of you experienced similiar issues?

Looking for your repplies. Tom.

Hi there. Anyone anyhow knows how to bypass this issue? Is bios modding a way to fix it?

Hi friend,
The Blacklist is used to lock all PCIe Cards not permited and Whitlist is for
all Cards only Permited !
So Dell has on WiFi Cards the Whitelist actived and I don't know about blacklist !
When Whitelist is actived Boot process stops and gave an error alert "System Halted . . .
remove . . . and restart" !
So if You didn't saw something of that there is a different issue !
Regards
