If the indica tor is glowing, the compute r is on. Als o, try turning the compute r
off a nd the n on.
If you a re us ing a n AC a daptor, ve rify tha t the compute r is re ce iving power
from the e xte rna l powe r s ource by looking a t the DC IN/Ba tte ry indica tor. If
the indica tor is glowing, the compute r is conne cte d to a live e xte rna l power
source .
