Latitude E6520 PCIe power saving

Hi,

Welcome to the Community. Click on start, control panel, power options. change plan settings, change advanced power settings, click on the + symbol next to PCI Express, Link state Power Management.

May I ask why are you trying to do this? PCI Express needs a continuous stream of data from the PCI Express device to the computer to keep them in sync. If the link state power management setting is set to conserve power the PCI Express device will basically power down and stop the continuous stream of data but it will need to power back up and sync before you can use it again.

Thank you

Thanks. I am trying to run an RME MADIface in the PCIe slot and the E6520 'blue screens' every time. A MADIface fourm suggested that this problem has been solved sometimes in other laptops by disabling the PCIe power saving.

Windows XP is the OS installed on this laptop and there are no PCIe options within XP power options on this notebook.

any other ideas on what could be causing the crash when a MADIface PCIe interface is connected?

Hi,

I do not see the option to turn it off in XP. I am not aware of this issue as well. Let us know if were able to get a fix for it.

Thank you
