    ...One suggestion was to replace the clock battery on the mother
    board. So he spent the 6 bucks for the battery and it worked! The
    machine boot right up and is working fine. Anyone ever have this
    happen?

    I had about two old pcs that behaved that way by virtue of a dead or undervolt onboard battery.

    Well, I have one ole laptop I might check then. :P I thought it was surely the power supply (luckily a daughter board for thinkpads...); but before I go digging into another ThinkPad to pull that peice, I'm going to check the clock....

    I remember when i was disassembling, that dam clock battery wouldn't unplug and I kinda yanked hard to get that sucker out of there. Since two of you described this situation, I hope to gosh that its just the battery. Don't think so, but I'll be posting a thank you to Hustler and you if so!!! :P

    I have a 486 motherboard that won't start at all (thought it well beep if there is no RAM installed). No video. I've been told that perhaps its something as simple as the battery, which may be the case as I've tried changing the RAM, CPU, etc.

    I take it though, that the board won't start up until a new battery is put in place? Or is removing the dead battery enough to get it started?

    It will likely need a new battery installed. That generation of
    mainboard may have the very common (back then) Real Time Clock and
    battery combo, often the Dallas DS1287 or DS12887. Can be a real
    pain to desolder / resolder, but I've done it successfully.

    You can get them on eBay, here: https://www.ebay.com/sch/i.html?_trksid=p2050601.m570.l1313.TR0.TRC0.Xds12887a&_nkw=ds12887a&_sacat=0&_from=R40

    Thanks. I really only want the board working becuase it has an 8bit ISA slot. I want to get a CGA monitor working and all the other boards only have the 16bit ISA slots.

    But I blew the powersupply because I absentmindedly connected the power to the motherboard incorrectly (ie, the black cables weren't in the middle).

    Damn!

    Yes and no. Sorry about the ambiguity. A bad cell could short out or
    provide a bit of voltage that prevents the BIOs from being preserved or the settings are corrupted. Pulling a battery could clear those settings, allow for any capacitors or volatile memory to clear. You can also search for a clear cmos jumper on a board, which will short out settings so they could be reset. A new battery may be essential to maintaining or stabilizng CMOS settings.

    It might be worth trying to remove the dead battery first, and hopefully you'll get the usual errors of RTC not set and Setup restored to default. If that doesn't work, you'll have to do some more troubleshooting, including trying a new battery. If it does work after removing the battery, you will want a new one, to maintain settings and run the RTC.

    Hmm, I recall plugging 8 bit cards into 16 bit slots.

    BUGGER! Hopefully you haven't fried the board as well. :/

    Yes, an 8-bit card can work in a 16-bit ISA slot. I remember doing that a couple times. I even seem to remember some 16-bit ISA cards still having some limited functionality when plugged into an 8-bit ISA slot.

    Later, VESA local bus came out, which was a 16-bit ISA slot with another slot behind it, and I don't think you had to fill all of that either.

    Yeah, I recall some of those 8/16 bit cards. They weren't common, but did exist. And yeah I had a PC with a number of 8 bit cards - CGA, voicemail system, SB (original 8 bit).

    Later, VESA local bus came out, which was a 16-bit ISA slot with
    another slot behind it, and I don't think you had to fill all of that either.

    Yeah, I remember those, though AGP seemed to quickly displace it for video.

    I think PCI replaced VESA local bus quite a while before AGP came around.

    I'm hoping so too. I'll try a different PSU, but at the moment, I need to fix up my battery pack and ensure it delivers the correct voltage first. I suspect the boards will not resurrect itself.

    I didn't think VLB was backwards-compatible, but that was a long time
