what is it, how can i reset bios via this violet "battery" ?

Take something conductive (I use my car key to jump motherboards and laptop CMOS') and touch both sides of the JCMOS. This should complete the circuit and reset the bios. This is similar to jumping motherboards where you don't have a case with a power header, and you'd use a conductor to jump the two power pins.

By JCMOS you mean this violet battery or this second "thing"?

Correct. The second picture has the two sets of tabs. The one labeled JCMOS2 has two tabs which must be shorted.

What was the original problem that made you want to reset it?

I flashed modded bios 3.5 for y510p, and it was working. But only for one gpu, and i was reading that SLI users have to flash ultrabay gpu too. So i did it. Without any error. Then i went to bios to check these new options and i undervolted cpu (-65). Then i saved changes, and i exit bios. After reboot, screen was black (like no light at all), my mouse and pendrive didnt light, only keyboard and power button was lighting. And i felt warm air from fans, after some time it was more warm.
I hope i explained it well.
