Charging IC usually doesn't affect  operation other than that the battery won't charge. Dell is not responsible for loss of use. You should have a contingency system available at all times if the role is critical and productivity is lost when a system is down. You can get 24 hour turnaround on support, but need to purchase that option with a system (Latitude, not Vostro/Inspiron) that offers it.
We shifted to Dell thinking that it is a reliable machine. not so..And the problem was compounded by poor service. For one machine, motherboard is gone and is not in stock for 22 days till date..But isn't Dell known for delivering customised products quickly? And the second machine, the diagnosis was "Charging IC" not working.  My question to the community is 1. How to yield a quicker response from Dell service (Chennai, India) 2. How to get compensated for productivity loss - our consultants are at client locations/work from home so difficult to arrange for an alternate machine.
