If your computer runs Windows, you need to install an ext4 filesystem driver to be able to read and write to the card after it was formatted in the Steam Deck.

Do you care about the battery life? Get the OLED.
Do you care about HDR, color reproduction, and black levels? Get the OLED.

Don’t care about either? LCD will be fine.

The bad news is if Valve wasn’t lying about this edition being strictly limited, then they are gone for good.

The good news is that Valve used this as a test to gauge consumer interest and economics of such models. As it sold out, this increases the chances that Valve will offer more case variants in the future.

Try resetting the USB-C port by entering battery storage mode

Try to recalibrate the battery. Enter battery storage mode https://help.steampowered.com/en/faqs/view/69E3-14AF-9764-4C28 and then do a full charge/discharge cycle.

If that doesn’t help, go to UEFI setup and keep this screen open until the battery runs out.

If that also doesn’t help, then contact Valve support to arrange RMA.

Sometimes this spans even three generations

Raven Ridge->Picasso->Pollock

Cezanne->Barcelo->Barcelo-R

AMD re-released the 3600 in a boxed WoF configuration (100-100000031AWOF), that one dipped below $100 when on sale, and permanently in late 2022.

This is possible, but Valve has blacklisted the addresses of many parcel forwarding services. So you may have to try for a while until you find one that works.

Also don’t use a free VPN, Valve can often detect those. Rather, use a free trial for a premium VPN. And don’t use a valuable Steam account.

Vampire Survivors
Don’t Starve Together
Towerfall Ascension
also a number of party games

Daytona USA (there is a PC port but it is crap)

This question gets asked like several times a week, for more detailed answers please use the search function. I will mention here only the two most important aspects:

1. For optimal charging speed, the power bank needs to support 15 V / 3 A output.
2. For being allowed to take it on an aircraft without additional paperwork, the limit is 100 Wh / 27,000 mAh.
