power up but wont boot up

I have similar. The repair boot flash drive does not work either and I cannot find safe mode.

I made some calls and spent over 30 minutes waiting only to discover that my system no longer has support. The tidbits I did get were slamming me for lack of proper setup in that the disk was not partitioned. I am not responsible for the lack of this as it should have been done when built. I was also told that I should have already removed the battery to fix then told to do so but there is no access as described.

Anyone?

If your device is unable to boot up even after powering on then it could possibly be that your operating system became corrupted. If the operating system is corrupted the easiest way to handle that would be to get the recovery media from Microsoft if they have it available and then reinstall your version of Windows RT that way. Before you go through the trouble of doing that you can refer to the motherboard problems section in the Dell XPS 10 Troubleshooting page in the event that it is simply a faulty motherboard or malfunctioning RAM.
