Xiaomi Air 12: Where is charge controller?

Wed, 28 Feb 2024 11:05:00 -0700

Hello,

One day my laptop stopped powering on.

Xiaomi official repair told me that problem is burned charge controller, it’s typical problem for that family, they don’t know which chip to replace and can only replace whole motherboard but it will cost almost same as new laptop.

Any chance to fix just charge controller ?

Attaching photo of motherboard, could anyone told me where is power controller chip ?

Motherboard rev R10-6050A2789401-MB-A01.

I found only MXIC 25L512e (seems like BIOS) and SIC831 (what is it?) chips on it.

Is needed chip under metalic cover ?

Any chance you could go further and explain how someone would change the LCD cable. Mine appears to be broken as the screen won't light up at all but computer can still output to HDMI.

Xiaomi Air 12: Need help with resetting the BIOS/UEFI

Fri, 19 Feb 2021 20:42:34 -0700

After “resetting” the BIOS password by simply not inputting anything, I’ve accidentally locked myself out of the BIOS due to the BIOS saying “password incorrect” whenever I input anything. Do note I’m using XiaoMi’s Notebook Pro instead of the Air, however the Pro is not listed in the “devices” list provided by iFixit.

Help is very appreciated, as I have tried removing the battery and letting it sit for a while, which is the only solution that I have found so far from other people, which does not work for me.
