The RAM is discharged causing all unsaved work and states to be lost.

In Windows, the registry sees this as a dirty shutdown and does a check disk on reboot. It is possible files that are critical are in the middle of a write (Reg keys included) and cause boot / performance issues in the long or short term. Although thats more of an OS question than a PC problem.
