A friend recently purchased a XPS 13 9343.  Apparently she had problems with the battery not charging when she initially set up the computer.  She claims she was instructed by the staff at the Microsoft Store not to operate the computer on the power supply, but that she should run the battery down and recharge it overnight.  She is under the impression that this is the way Dell intends that the computer be operated.  Given that she is not very technical, I'm a bit skeptical about this.  I suspect she may have misunderstood these instructions.  Is there any truth to this? Is this an initial "conditioning" procedure?  I did read another post that described a similar procedure to reset the battery meter. Does that procedure apply to this computer?  I've searched the Dell site, but I can't find any specific instructions for this computer.  If anyone can point me to some more info, I'd very much appreciate it.

Thank you.
