@vijaypatel017 - Sorry you’ve changed so much, I don’t know where to even start here. Rarely do I find my self changing our parts without a firm grasp of a diagnostic process that compelled me to change out parts which haven’t any physical damage or corrosion visible.

What is the history? Did this get liquid damage at some point. While you replaced the trackpad the keyboard or even keyboard cable may be bad.

thanks for reply,

Yes it has a liquid damage near charging circuit, also near track pad IC, and keyboard cable burn, so i have replace keyboard, then correct charging circuit , charging and discharging work ok, then i have also replace trackpad IC UT360 and UT301 also, and also nearby capacitor CT360, CT361, CT400, LT400, CT302, CT303.

and nearby CT302 and CT301 capacitor minor track damage, i have corrected and fix it.

after correcting trackpad and keyboard work sometime may be 5 to 6 hr, then both stop, but external mouse and keyboard work ok alltime.

and sorry for late reply.
