Re: Laptop blinking light
According to the manual for your laptop I found on-line, that indicator blinking orange meas that the laptop is running on battery and the battery has less than 10% power left. That means that the power adapter is not powering the laptop and not charging the battery.
This could mean the cable that connects to the power adapter is not fully inserted, or the cable is bad, or the plug isn't fully inserted into the laptop. The plug or the jack could be faulty or the adapter itself has failed.
Check to make sure the cable and plug are secure (also make sure the electrical outlet you are plugged into has power). If nothing is lose or frayed then you can try another power adapter. When looking for a replacement power adapter, make sure you match the voltage EXACTLY. The current rating must be the same or HIGHER. Lastly, make sure the plug is correct with the proper polarity.
It is also possible that the internal circuitry on the motherboard has failed which would mean you would need to take it to a shop to have the motherboard repaired or replaced.
