I'm working on a lenovo yoga 7 16arp8 that had a bad charge port. When I replaced the port the laptops charge light will come on and stay on now, but when I push the power button the power light will come on for a couple seconds and then go right back out. I'm suspecting a bad bios, but when I went to read the bios to start the process of getting a new one it I found that none of my programmers will read the IC. I mainly use a T48 with Xgpro. I also have a ch341 and it's software that I use for ps5 uart and bios's, and a EZP2019+ and it's software.

The chip is labeled MXIC MX77u2565ofz4142...

I got the part you linked in and it was the correct one. Only problem I ran into was it wasn't the only issue. The SRKMA chipset chip was also shorted. I replaced the blown mosfet and check around the circuit and one 0ohm resistor was also blown so I replaced that. Plugged everything back up and still not life. Checked again for shorts around the mosfet and two capacitors right above it were still shorted. I removed the mosfet and they were still short. When I injected voltage in the only thing getting warm was the SRKMA chipset. When I pulled it off the shorts went away on the capacitors above...

I just ordered a pack of those so hopefully they will work out and I can get this one up and running. I appreciate the help finding it....

I was only able to find them on aliexpress, but am not sure of the two options listed which would be the correct one for this laptop. I didn't have any luck finding a datasheet online. I know from experience sometimes these one letter differences don't matter, but I also know it can do something important like change where VCC is on a chip.

Would be just amazing if someone at razer would leak their schematics like at the other laptop manufacturers.
