Ok , i am from EX- YU .

Doing some board repairs.
Laptop had a BIOS issue - laptop model SVE151J11M turns on, no picture, found bios on this site, flashed, got picture, boot to bios via VAIO button. after reset, got black screen, no picture. new start, again get picture, after reset, no picture... one thing i have noticed is that i cannot read EC chip version. says UNKNOWN
Reflashed old bios again, this time have picture, can go to bios via VAIO button, can setup bios to boot, however, after reset i get to VAIO screen and it constantly gives me no operating system found. i shut down it and start with vaio button, however every time bios gets reset to factory defaults.

i have replaced cmos battery, here is the schematics:
http://www.s-manuals.com/pdf/motherboar ... matics.pdf
my board is revision f, schematics is other revision, but it is the same board with same chips.
i have checked 3v passing diode d18
also i have measured 3v on pu110 , pu111 and pu112 , i do have 3v on pins which are connected to 3v rtc.

i have connected SVOD programmer via keyboard connector to the motherboard USB from the left side ( USB 3.0 ) and to my laptop. I could not detect Novotoun EC chip.

i guess EC has a bad firmware and it cannot be detected , thats why PCH is giving signal to reset bios?

does anyone here knows how to stop BIOS reset?

Thank you for your help!

Спасиьа!

your kbc is not programmable that's why it does not detect it

here is the list of those that are programmable

ene kb9016 programmable
ene kb9018 programmable
ene kb9022 programmable
ene kb9028qc programmable
ene kb9010 programmable

SMSC MEC 1609 programmable

so this EC is not programmable? why am i getting error EC version Unknown inside of BIOS? why does my RTC always resets, it resets during power plugged in, during 3v cmos battery in, every time i start it it returns to default settings.

do i need to program EC? i have replaced many kb9012 , ite 8587e ite 8587e and they never made any problems.
i just replaced them and it worked fine.
sometimes i bought new ec ite 8587 and replace the burned one and it works, i plug in programmer and from their official page for that board model i download ec firmware, upload it on ec controller and the board wont start anymore :D

so this may be bios issue? i am going to flash some other BIOSes to see if it will work. Thank you for your help
