I've been having trouble with my laptop. It only runs when plugged in.
The laptop model is dell inspiron 7560. The led blinks orange 4 times the white once.
I tried unplugging the battery and draining the power.. Some how got it working again without the adapter.
Next day morning its back to the same state. This time I tried doing what I did last time but it didn't work.
3 x Orange and 1 x White indicates a CMOS Battery Failure, may need to replace the CMOS Battery (little round battery on your motherboard). If it really is four i would pose the question to Dell and they will let you know inside of 48 hours.
