Title: Nvram voltage trigger
Post by: Hertz14 on January 22, 2021, 08:44:24 PM

Anyone know the voltage line for the backplane battery on a V20? I got the error- nvram 1, changed the batt. Three days later, same error. Battery tests out at 3.11v


Backplane issue maybe?


Thanks in advance!

NVRAM is not the backplane battery, it is the one inside the MPU.

Well then.. that makes sense. I’ll have to order a couple, batteries plus didn’t have the n type. Dont think a standard 2477 will work as the n has the lip on it.

Yeah, you need the N type.
