    Hi all,

    I recently got out my mid-90s Performa 6116CD to see if I could get it running again after probably 10+ years of sitting in a storage bin.

    When I powered it on, I got the startup chime and could hear the hard disk spinning up okay, but no image came to the monitor--an Apple Color Plus 14" display. The power light for the disply did come on, though.

    I know the display hasn't been stored as well as the computer itself, so I picked up another used CRT monitor (NEC Multisync 97F) and a VGA-DBA15 adapter and gave things another spin. The results were the same. Also, I know the NEC works as it successfully displayed an image from my current computer. The Apple display did not work when I hooked it up to the current computer.

    Anyhow, having poked around the forum a bit I see that people talk about replacing capacitors and cleaning the motherboard a fair amount, and also possibly replacing the PRAM battery.

    Based on the particular symptoms this Performa is having, do those seem like the best avenues to pursue? Or is there something else that might be good to try out?

    Assuming that the rest of the hardware is OK, your first step will be replacing the PRAM battery. Video will not come on (and it won't boot) if that battery is dead or missing.
    The 6100 powerMac/Performa series was well known, even when new, that a dead PRAM battery would prevent booting, with the main issue of no video.

    If the battery is dead/missing press the power button three times in quick succession ie on-off-on, it should then come on with no battery in it (this trick also works for some of the other older Macs that otherwise won't come on properly without a working battery). If the battery is dead you should remove it as otherwise it will probably leak and damage the board.
