power adapter flashes when plugged in to laptop, unit wont power up
AC adapter light flashes once plugged in to laptop. It then has to be removed from power to reset it. Kinda like it senses a short when plugged in and goes into a safe mode.
I have replaced DC input assembly inside the laptop. Checked all connections to the best of my limited ability. Looking through forums , the next step seems to be replacing the mainboard. Just wondering if there is a test to determine if this is really required.
Thanks for any info
