      First of all you need the schematic.
      Check the voltage at Q0903 for a start.

          HP Elitebook 845 G8 dead, only caps lock flashing 7 times. Charging light always on
          by esqmooo
          Hello everyone.

          This is my development machine. I've been using it since two years and half without any problem except sometimes it wouldn't wake up from sleep.
          Lately the issue became more frequent and powering it up would take few seconds to show the POST screen.
          Then the computer refuses to power on at all. Now only the caps lock button flashes 7 times then stops. The charging light is always on whenever a power source is connected (battery or charger).
          I tried long pressing on the power button, after several seconds it would go off then when the button is released...

          Strange! Acer laptop not powering on but charging the battery (orange light on when charger and battery plugged in).

          Hello Everyone!

          I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died.          ...

          HP Elitebook 850 G8 CAPS lock flashes 7 times and charging light always on
          by esqmooo
          Hi,
          I'm facing this issue since this morning. When I try to power it on, the CAPS lock light flashes 7 times (or 6 if not counting the first one when the power button is pressed). The charging light is always on as if the laptop was connected to the charger. The issues started gradually where it would flash the light but after trying multiple time it would power on. I tried to open it and I noticed one coil "1R0 2127" gets hot when the charger is connected. Note: the charging light directly comes on when the battery is connected or the charger is connected.

          ASUS X54H laptop thinks it's always charging even with charger unplugged
          by flat-earther
          The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

          Windows also shows ''Plugged in'' when charger is not connected.

          This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
          Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
          If I let battery run out and say it has 3% Windows will...
