      Lenovo g50-80 charging led flashing but laptop not switching on
      by B2L_Repairs
      I got a lenovo g50-80 that shows charging led (orange LED flashing) and when I press the power button the white LED comes on but the laptop doesn't switch on. The fan spins for 2 seconds when I press the power button then it stops. This problem started when my charging dock broke the connecting wires and i soldered these wires back but I might have mixed them. I ended up buying a new charging dock but laptop never switched on it just shows flashing orange LED when charger is connected. Could the super io be bad? I don't know how to go about diagnosing and I can't check any board view since this...

      Issues with Charging My Lenovo Legion Y530 Laptop
      by DragosGiGi
      Hi! I have a Lenovo Legion Y530 laptop that has started having problems when it's being charged. Sometimes, when I plug in the charger, it completely shuts down and I can't turn it on (as long as the charger is still plugged in), not even the LEDs light up. If I unplug it, it starts up normally. To get it back to normal, I have to leave it off for 20 minutes and then try to charge it again. At the moment, I don't have another charger to see if it is the cause of the issue.

      I tried to discharge the residual power, I removed its battery and the BIOS battery, but unfortunately, it didn't...
