Dell 9200 (DXP061) CMOS battery update
Posted by jpluimers on 2022/04/04
If the CMOS battery of a Dell 9200 (DXP061) the BIOS looses all the settings and resets the timestamp to 2007-11-22 midnight.
Date timestamp is likely because that’s the date stamp of BIOS version 2.5.3 which is still the latest for both the Dimension 9200 and XPS 410 (which are identical: XPS was for the consumer market, Dimension for the business market, only a few options were different):
- [Wayback] Dell Dimension System BIOS, 2.5.3 | Driver Details | Dell US
- [Wayback/Archive.is] Support for Dimension 9200 | Drivers & Downloads | Dell US
- [Wayback/Archive.is] Support for XPS 410 | Drivers & Downloads | Dell US
The manual at [Wayback] dimension-9200_owner’s manual_en-us.pdf mentions how to change the battery, but forgets to mention it is a CR2032.
Luckily [Wayback/Archive.is] How to Replace a CMOS (coin-cell) Battery on Your Dell Desktop | Dell US had that information.
