pch is not damage for me .. there is a chance in ec damages .. there is a communication between battery and ec and ec between charging ic so better to replace the this ec chip.. i solve a problem of asus x451ma that the battery icon is not detected ( battery pluggedin) but not charging when adapter is removed laptop is not powering off , i change the ec and the laptop works perfectly.. i found out that the sda / scl lines reading was 400ohm .. maybe you can get something on my case to your case...Leave a comment:
