Hey guys!
I was running an older BIOS on my NP300E4A-BD3BR and I found this forum and managed to download Fabionfsc's bios mod link.

I just installed and after first reboot my screen started to show some weird stuff. I waited 2 minutes and forced a shutdown.
Now everything is working again, I can boot to bios or my Windows just fine.

But no battery is recognized and on Windows OS I can see the battery icon saying: "0% available, plugged in not charging".
I went to Samsung product page and downloaded a Bios Updater, and it says my bios is the lastest but I can download a EXE to flash again the bios.

Unfortunately, as soon as my battery is "dead" just after I run the EXE it says I should have my laptop plugged in AC and with battery with at least 30%. And now I can't "undo" the bios mod.

What can I do?
I bought a new battery and it keeps saying "0% available, plugged in not charging".
I tried to use a app called find_gz.21 to extract BIOS from this exe file but when I try to start the extract it says "Unable write file...." even if I run as administrador.

Hello
Thank you for this bios ... i flashed it on my samsung 300e4a-s0esa but i have some notes to mension maybe because my model has dual graphic cards :
1. Smart battery charge is missing ( the option to limit the battery charge to 80% only
2. No AHCI available ( essential for hackintosh )
3. Whenever i for my Intergrated intel card off it keeps on and my nvidia is forced off perminently ... this is very hard to understand i thought i could do this easy
4. In the IGD settings when i press on tv settings i get a garbled screen in the bios
5. If i switch to low resolution bios screen the whole system freezes alot and i cannot use my internal laptop keyboard ... had to keep using high resolution graphics for this one

this is my original bios
