I have a Dell XPS 15" 9550 and have done a reset/reinstall of windows and dell support app says all drivers are up to date but the laptop freezes when on battery power. Looks like the battery is ok.
If I remove ac power, sometimes it freezes instantly, sometimes trackpad will work but can't alt+tab and stuck on that one screen. Sometimes after the freeze get blue screen.
I tried putting Ubuntu on a usb thumb drive and could boot to it on battery power fine, so that suggests the battery is ok and perhaps it is a windows driver issue.
I tried starting up to the bios screen and removed ac and that didn't freeze.
How do I tell in this fresh install if a driver is causing the freeze and which one?
What other troubleshooting can I do.
