No, I do not know where is a reset pin of BIOS.

Try to disconnect NVRAM battery.

Wait 15 minutes and reconnect again.

To reset BIOS this NP530U3, only disconnect all power supply (MAIN battery, CMOS battery and power source). And hold press POWER button for 1 min.

Hello,

I have seen many screens with model number LTN140AT21-XXX for this laptop. My laptop NP530u4b has a screen LTN140AT21-802. I would like to know if I can use a LTN140AT21-002 screen, or if only is good a screen with number LTN140AT21-8.

thanks for your help.
