KBC chip replacement on Lenovo Z50-70 motherboard


I have to replace a faulty KBC chip "IT8586E 1435-FXA SC25NA" on my Lenovo Z50-70 motherboard. I have been looking all over the Internet, but I am not able to find the exact same model. The only common notation I can find is IT8586E FXA, but the rest of the characters are always different. For example I found "IT8586E 1306-FXA ECZ71A".

Is there any way to obtain the original chip? If not, are those similar models with FXA notation compatible with my nm-a273 motheboard?

Thank you in advance for any help. :-

It's possible that the 1435 on your chip is a date code.  This is WAG based on not much - but maybe it gives you something else to search on.


good luck,
