Dell XPS 13 9350 doesn't boot up

My Dell XPS 13 9350 was suddenly dead.

When turn on the notebook, after blinking power button LED for a few seconds, nothing happen.😞

At that moment, it still did take only a few months since I got this notebook at auction.  In my case, running out of battery ( CMOS BIOS battery ) seems to be cause of the issue.

When get voltage of the battery lower than the level required to boot up bios, this issue seems to appear.

One of the solutions to avoid that this issue would happen again is that you should not charge battery with AC adapter during Power down. If you want to charge battery, you need to do that during power on.

When you face the same again, detach and attach of the CMOS BIOS battery might be able to resolve the issue.

Good luck!
