RE: XPS 8900 freezing
I'm using a bluetooth mouse and I just now disabled "allow this computer to turn off this device to save power" for intel bluetooth and the same for intel wifi. I had this bluetooth error on the factory dell wifi/bluetooth card and on the current upgraded 802.11AC intel 7265 card
This computer is on a home network, 2 are using windows 10 home 64-bit like this one and 1 is using windows 7.
I have the latest chipset drivers and nic drivers, all are from this month. I ran intel's driver checker and it verifies the version number and release date for all my drivers and says I have all the current ones, also showing the numbers of previous versions so you can compare.
