Check RTC circuit completely.

thank you for your response.
i checked it i didnt find any problem.
ichecked the charging circuit
internal battery rating is 14.8v and when i connect the battery it has around 16.5v and when i connect the charger i have around 17v on battery pin
last night i charged the battery fully and left it for the night today i came back it wouldnt turn on with battery only. when i connect the charger device turned on.

Remove the battery.

Does the unit turn on every time with only the original power adapter ?

no i test that too, at some point it wouldnt turn on at all with or without battery
i reprogrammed the bios then it turned on after awhile same thing happend but with changing bios ic and program didnt power on anymore.
i think the pch maybe be the problem
