    When I disconnect my i5 XPS13 (2015) from power, suspend and resume the CPU gets stuck at 0.48 GHz according to Task Manager. The system is basically unusable until I reboot.

    Has anyone else encountered this? Anyone with a fix?

    Do you have an i3 model? There is a new bios driver (A03) that addresses CPU performance issues in i3 models.

    Yeah, I installed the version for my laptop yesterday. Was there anything you needed to do after installing the new BIOS?

    You should only need to flash the BIOS. It may just be the case where the patch addresses an issue separate from yours, unfortunately. I can't be too certain on its specifics as I'm still on A01 myself (i5 model).

    I reinstalled all of the chipset drivers and the problem seems to have gone away.
