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.

Possibly a bad battery, even fairly new not unheard of.

If the hang occurs only on battery power, I suspect a power plan problem. Most OEM laptops are automatically set to run an economy power plan whilst on battery power, providing less power to hardware. While this is good for battery life, these type of settings can cause performance issues and sometimes hard hangs.

 

I would suggest you change your power plan, on battery especially, to "high performance" for troubleshooting purposes - https://www.howtogeek.com/240840/should-you-use-the-balanced-power-saver-or-high-performance-power-plan-on-windows/ And you need to go into the "advanced settings" of that "High Performance" power plan ensuring that all the settings are set to highest-performance level, especially any graphics card related settings, whether battery or "plugged in."

Thanks, this was one of the first things I tried.  I double checked and all the settings are maxed out even in battery mode.  Any other ideas?

FYI, I found a suggestion on another forum to delete the battery in device manager, thus forcing re-installation of the battery driver.  This seems to have solved the problem.
