    Lenovo Y540-15IRH

    hello, I have a lenovo legion y540 (nm-c221 rev 2.0), it suddenly turned off and then started to restart continuously, I reprogrammed the bios. After the reprogramming, the fans turned on for 5 seconds and then it turned off completely. The PU601 started to heat up and I discovered that there was an internal short in the ITE so I ordered a new one and put it on the board, but the laptop still doesn't give any sign, it doesn't start. I also read here on the forum that the IT8226E-192 on this model rewrites itself, is it true or do I have to rewrite it? I don't know what else to do with it...

    Help me, please 🥺

          ok, so does the new IT8226E need to be programmed? I checked the continuity on pin 11 (VCC) with a multimeter and I have 460 mV, but if I power it with the laptop, the voltage is 0.

          Can you help me with a .bin file for this laptop model?

                      I checked again and I don't have 3V voltage when I press the power button. So is it from ITE that it is not programmed?

                          You should have the 3VS , no need to waste time programming the the EC if that 3vs is missing

                              I also rewrote the bios with someone here on the forum, is there a chance it's a bad bios rewrite?

                                  Lenovo T14 Gen 2 Type 20XK Model 20XK0069US Odd Charging Issues
                                  by coasterghost
                                  For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

                                  Lenovo Y50-70 only charges when turned off.
                                  by Darren Hibbert
                                  I have a Y50-70 gaming laptop. It has a problem where it charges up fine when the laptop is off, but when it's on, it doesn't.
                                  I've tried a new 135w charger + new Lenovo battery and a new charging port but it made no difference.

                                  I've updated all the drivers and still no difference.

                                  Could it be down to a dodgy chip? I'll see if i can find a schematic and someone on here might be able to direct me where to test

                                  Many thanks in advance....
