Pomóżcie zidentyfikować rezystory na baterii Lenovo L22m4pa1.
Laptop jest prawie nowy, po zalaniu. Chcę spróbować naprawić, na ogniwach po jest 3,7 V (4 sztuki).
Podczas czyszczenia odpadł jeden rezystor. (drugi zgnił, ale niby sprawny).
Jeszcze uszkodzony bezpiecznik D6SC4 (już zamówiony).
Dzięki

Hello!

Remove the silicone coating from the board and post a clear picture with visible copper traces around this resistor. Also post a clear picture of another area of the board where the copper trace from the right side of this resistor is connected to.
Also post a clear picture with visible markings on the chip.

Be prepared, that the battery controller is most probably blocked now (...after voltage drop etc.) and without special tools line NLBA analyzet you wont be able to reset the controller and make the battery charge/discharge again, event you succeed to fix it from hardware point of view.
