Hi, laptop G510 with COMPAL LA-9641P motherboard. Flooded areas cleaned. There was shortcut in B+. DC converter SY8208BQNC was broken. Changed for new one There was also shortcut in +3VLP, KB9012QF was broken. Changed for new one programmed. Present situations. B+ is fine, albo +3VLP is fine too. There is no ENABLE for DC/DC converter. EC_ON 3,3V - OK, MAINPWON - 0V - not OK. What conditions need to be reached for KBC to have MAINPWON on HIGH LEVEL? Or it is internal flash issue? Any help appreciated. |
