I recently picked up an F720 that had been off for over a year or two. The batteries were dead but it was still bootable but would complain. Fun part was I zeroed the disks and went through the ontapp install just fine and upon reboot it would shut itself down after spitting out nvram warning messages and there is no way to override this in 6.5.x so off to buy batteries I went. Everything works fine now that new batteries are in.

Im not sure why yours is acting up if its just the nvram battery

it was unplugged for more than one year as far as i know i will try to replace the battery , but i dont understand why it should bug it so much , i mean its a backup battery after , if its dead its not a problem , just nvram is dead right ?

also i see there is a huge plumb rechargable battery inside , what its for ?

thanks cb

How long was it unplugged? The NV-RAM battery might be dead, which

will

cause you problem on booting up. However, usually you will see message

on

console.

Hi,

the console and the lcd shows the same thing , i mean it depend of how loaded it is , if i leave all cards inside and so pci scan takes

longer than

if there is no card inside to it freeze at the pci scan , if i remove

all

cards , it jumps until Testing Memory and freeze at this point so its undependant of the boot stage , but dependant on the number of seconds

since

the power on .

Hook up the console and see what it says? Anything showing on the LED display?
