You are maybe confusing DPC latency with audio latency. There is only a faint connection between these two as in "raising ASIO buffers may or may not help avoiding dropouts due to DPC related usurpation of the CPU".

Not laptops in general. Some models suffer from this, others don't. It's also not always the ACPI battery services causing DPC problems in laptops.

These problems are not confined to Laptops, some desktop PCs have problems with DPC latency as well. This is a rather complex issue and generalizations are not possible since the culprit can be a lot of things from faulty hardware to bad BIOS implementations and of course drivers.
