I recently purchased a used MSI GS66 with password locked bios.
If I'm understanding correctly, I can fix this by re-flashing the bios. Except I need a copy of the original bios because the updates don't have complete information.
Maybe I need to download my existing image and copy information (something something DMI) from there to the newest BIOS update downloaded from MSI?
Or maybe I'm supposed to request for the original, if any has it unlocked can they send it to me?
I'm tried following different threads here, but its confusing because MSI...04-30-2024, 06:58 AM -

Need help here...
I'm new on the forum and I'm not professional in electronics so i ask sorry in advance for eventual errors...
As title says, i have a LA-H323P dead.
Now, little background.
The computer was working fine, just seems that the cable of screen was dying because it had the classic color problem, sometimes green, sometimes violet, sometimes perfect, but anyway working.
When i opened it the battery was so fat that was seriously near to explode.
So i removed the battery... and turned on the notebook... that was, again, working perfectly fine....04-28-2024, 03:31 AM -

Dear collegues,
the owner of this machine brought it to me saying that suddenly one day the display didn't turn on anymore, he tought that all the machine was damaged but it turned out that the MacOS starts good and stays on, and that connecting it to an external display it works without problems.
If you take a look into general settings, you can also see that the internal retina display is recognized as connected by the main board but for an unknown reason it doesn't turn it on.
I've tried to put a bright light towards the screen but I can't see anything, any shadows or apple...Today, 05:50 AM -

While wall mounting, I mistakenly picked a screw 0.5cm too big than the clearance and damaged the trace and one of the part (a capacitor, I think) on the board. Images attached.
Is this repairable or will I just have to get the entire board replaced? Please guide about this.[U]Hardware Details - Samsung LC24FG70FQWXXL (C24FG70) Monitor with the board model (BN91-18169A) perhaps aka (BN41-02548A)[/U]

there is no reaction, it hangs at 20 V/0A. There was a little corrosion in the u7650 area. Replacing the u7000 did not help. Tell me, what else could it be? PPBUS_G3H=12.9V
