    whats the condition of missing?
    No voltage only if adapter its in without pressing power button?
    DJ_RICOH you misunderstood my statement.


    1. I am suggesting mtherana to measure the voltages across the capacitors. We are expecting 3.3v, 5v, 1.8v/1.5v, 1.05v, etc. If one of those is missing, he should check the corresponding regulators.

        Acer Aspire 5 A514-55 - won't power on, no charger LED, battery not flat - usual suspects?

I'll describe the symptoms and my findings so far, and I would like to seek guidance and suggestions on possible suspects in terms of cause/component failure. My initial thoughts are battery charger IC and/or ideal diode/MOSFET (that switches between incoming DC and battery power), but I could be totally wrong on this.
        1) Laptop was working fine on battery, then user realised battery was running low. Plugged in AC adapter but noticed it was not charging (LED on AC adapter plug did not light). Eventually shut down
