Customer told it discharged the battery to 0% and now laptop will not power anymore. I removed already rtc battery and checked that I have 19V stable. Battery is charged, so battery charger is working ok.
It is second time I face this problem. Any recomendation? I found only one bios but it is not powered, as I think it is PCH bios. This board have KBC bga 9010. I dont know if this could be firmware problem. Any idea?
