Mine arrived at the same time as yours and had issues with both the battery and the m.2 port, Valve did an rma for it a few months ago. If you’re in the EU, then you have 2 years of warranty instead of 1.

I would start off with trying to recalibrate the battery, but since it’s probably impossible in your case then just make sure none of the internal connectors came off, then try Steam Support again if that’s not the case.

I literally copy-pasted all the important folders instead of cloning and it worked.

Is there a way to choose where the games get installed? I prefer keeping my non steam stuff on sd cards.

Dos and Windows seem to be functional, but I cannot log into Epic as all the login options either fail to open the browser or get me stuck at captcha as the mouse cannot go to the bottom 1/4 of the screen.
