My Dell XPS 15 (9550) freezes after being on battery power for 15-20 minutes. Becomes unresponsive, need hard power cycle to restart. (Note I don't have any issues when charger is plugged in.)
Seems like maybe a power issue, as I've noticed the audio and keyboard/trackpad fail first, and display fails last.
I though it might be the hard drive turning itself off, but I disabled that in Windows settings and this does not make a difference. (It's an SSD anyway).
I am using Windows 10 version 1709 Build 16299.192, but this has been happening for a while. 16 GB Ram, 1 TB SSD, Intel Core i7-6700HQ @2.6 GHZ
Please let me know if any other info would be helpful. Thanks very much in advance for any help.
Edit: Note I've run all the Dell diagnostics, and it passes all of them.
