[QUOTE="powermac G5, post: 1253014, member: 70892"] I refurbish said to be dead Mac pro's and 2 instances I have noted with auto powerups upon plug in is either is a bad CMOS back up battery, bad memory card or bad memory riser. First replace the neglected back up battery flat lithium CR2032 then test. No success? Remove both memory risers and only place the memory cards that originally shipped in one riser. Install just the one riser in top bay and restart. No success? Try the second memory riser in the same fashion explained above. No success, you will need to verify memory cards are good. You will most likely reach success with replacement of the back up battery. Post your results. Thanks [/QUOTE]
