HP 15 ( R62 ) dont turn on : POST CODE F9

[delphi_firebird]

Hello ,

I have an HP15 R62 DA0R62MB6E1 REV E motherboard that won't turn on .

I flashed bios , change RAM , CPU .. same problem .

The debug card show that it is posting and stops on code F9 .

Could someone help me to figure out the solution?

Thank you by advance .

The reason can be so many things. you need to descrive what voltage rails are present. Does the dc jack light glows?? Check +3VA_EC, EC_RSMRST #,PWROK #,PWR_SW #. on kbc pins
