What Happens When I Remove the BIOS (CMOS) Battery?

Issue

My console is being transported via air and the BIOS (CMOS) battery must be removed during transport. 

Explanation

The BIOS (CMOS) battery stores persistent memory for BIOS and the Date/Time/Location settings for your console. Removing this battery and putting it back in will cause these features to reset to defaults. Unless otherwise altered by an end user, the BIOS settings on your console are also the default settings.

The BIOS (CMOS) battery does not store data for the Show File Archive, however it is highly recommended that the Show File Archive is backed up onto an external drive before the console is transported.  

Replacement Battery

CR2032 batteries are commonly available.  CR2032W can be sourced online (search for "CMOS battery 2032").  It is not possible to replace just the battery part of the CR2032W as they are manufactured not to come apart.

CR2032W may be available from an ETC Dealer; the ETC Part# is BT161.

Please check your console and purchase the appropriate style of replacement battery.

Which battery do I need for my Ion?

Early versions of Ion with a DVI Splitter should use CR2032.

Early versions of Ion with two DVI ports and one VGA port should use CR2032.

Late Ion classic with two network ports and a Display Port connector should use the CR2032.
