Dell Inspiron 15-7570 Bios corrupted

Hi everyone,

Unfortunately I modified some Bios options and now the laptop won't start. It doesn't reach the Dell splash screen, I get only black screen, led blinking regularly once per sec and fan spinning very fast.

What can I do?

For instance will removing CMOS battery help me in resetting the Bios options?

Thanks in advance.

To reset the BIOS to defaults, power off, unplug the system and disconnect the battery.  Hold the power button for 30 sec.

Then restart.
