hi guys! thank you for all the help.

I needed to ask if this motherboard requires an EC firmware incase the I/O controller is replaced or it reads it from the main bios.

see if the I/O chip is programmable, or not... if it is programmable, it definitely needs EC bios.. here on the site you can find data about programmable and non-programmable I/O chips..

I've used it too with CH431A programmer, the laptop I've found in the trash is now alive again. 😉😁
Just one info about, the BIOS was edited to delete all the personal info about the original owner, I guess, but are those info needed somehow or I can leave it "invalid"?
Also, the bios is not recognizing the external RAM (4gb ram stick) but only the soldered one, but this may be a problem on the ram stick.
Thanks!

If you saved a backup before flashing the bios the DMI should still be in your backup

I did it, but looks too corrupted.
Anyway, about the RAM, I was mistaken, I've cleaned the contacts and now works.

hello! I've succesfully replaced and flashed my EC (thanks a lot btw), but now the fan runs at full speed and never stops (except obv. when powered off). This laptop came to me not powering on, had to replace EC, pmic and reflash corrupted system bios (I have the original dump). Any hints?

post S/N, full name and model, motherboard model, TYPE,etc.

post the contents of the bios chip even if it is corrupted..

first of all thanks peste. I should have taken more care in my description of the problem

Here's the data:

http://support.lenovo.com/qrcode S/N:PF0QUJXF MO:PF9XB7407059 MTM:80ST0087AR


I should add some observations i made:

1- This MB works just fine except for the fan speed problem? Loads windows and everything else.

2 - The fan starts at slow speed and then accelerates when entering boot selection

3 - The signal EC_FAN_PWM starts modulating ok, and then goes to 3v at the time detailed in point 2 and stays there

4 - I dont know what to expect in EC_FAN_ANTI

5 - related to 4, I have yet to search info about 5 wire fans

thanks again

bios extracted from Lenovo website update for 310-15ABR Laptop (ideapad) - Type 80ST
DMI 2A3000 - 2A4FFF

hi there, badcaps web rejected the bin format, I see you uploading as .rar, will do the same with the original bios. I dont know if I understand what to do with yours. I can tell you that I've already downloaded that bios from the lenovo site, and updated it within windows. In the process it updated the ec bin too.
