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.

Any advice from more experienced technicans?

Resoldering KBC bring laptop to life.
