  We are in the process of obtaining a complete sample of exploratory X-ray
observations of broad absorption line (BAL) QSOs from the Large Bright Quasar
Survey (LBQS). This survey is composed of short (5-7 ks) Chandra ACIS-S3
observations designed to significantly constrain X-ray fluxes and hardness
ratios. Our sample avoids the selection biases of some previous surveys while
providing X-ray data of similar quality. Of 17 BAL QSOs observed to date, 13
are detected. In general, our results are consistent with absorption as the
primary cause of X-ray weakness in BAL QSOs. As found by Green et al. (2001),
those BAL QSOs with low-ionization absorption lines are found to be notably
X-ray weaker than BAL QSOs with only high ionization lines.
