Repairing an Acer Aspire One 753 with no power
Owner reports that it was working fairly recently, but all of a sudden fails to power on.
No signs of life at all. No LEDs lit when connected to charger.
Things tried
Power reset
Tried simple power reset / static discharge (disconnect power, remove battery, hold on button for over 30 seconds, reconnect battery and power).
Charge overnight
Try charging for a long time in case it's a discharged battery.
A laptop with a battery discharged to its bare minimum may not power on even when connected to power. This is a built-in protection to prevent further battery discharge of a battery already at its minimum.
That said, it doesn't work with the battery removed, either.
Check the charger
Doesn't look like it's Acer branded, but it has the correct output rating - 19.5V / 2.15A.
It's rated 19.5V. Using a multimeter, it's got a reading of 19.37/8, kind of fluctuates between the two.
Remove/reseat components
Check continuity to battery pins
Check power jack connection to motherboard
