i am making use of lenovo y460p and before the replacement of motherboard ,it played music without stuttering. i now have a motherboard, with its updated chipset and BIOS , which is associated with sound stuttering under Windows 7 x64. after the removal of battery from the laptop, the red DPC latency spikes go away . although this eliminates the DPC latency problems, there is no portability issue without its battery. i wanted to know whether it is possible for an updated BIOS for the that would solve the DPC latency with the battery in the laptop?along with the sound slutter problem exists and continues.
