Lenovo IdeaPad Slim 5 16IAH8 нет питания

Hi,

I have a repair, a Lenovo **IdeaPad Slim 5 16IAH8 **laptop. It's seems a 1 year old only. No display, no post, only blinking power led. I opened and investigate and found this burnt IC, but I cannot see the details properly and or the label of the IC.

Can you help me recognize this so I buy?

**Thank you. See attached.

Anyone?

Post more pics of this logic board. The part is 100% from Richtek but the critical first 2 characters are not legible in the shared pic. The same part may be common to other Lenovo models.

On the logic board will be white silk screened markings. Post those as well.

Sure, участник. Please see attached.

Your board number is 'LA-M652P'. Search out pics of this board to locate this mystery component.

From your original post, we know 100% the part is from Richtek and can make out that the first character is a 'P'.

Once you know the 2nd character, you can solve this mystery. The Richtek part is 'Px=' but we do not know yet what value of x.

Pour IPA (alcohol) onto this part and apply your phone torch light to best guess the 2nd character and post a fresh pic or guess.

Thanks участник, I can't still find the label of this IC. Maybe because this is new model?

I finally found it. It is PF = 9G 45C. Thanks

It's not "pf=", it's "ml="
