A buddy of mine Grandson's Desktop PC would not boot up. He checked out a ard. So he spent the 6 bucks for the battery and it worked! The machine boot
was but it sure is something to think about. ;-)

machine boot right up and is working fine. Anyone ever have this

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.Xds 12887a&_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).

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

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.

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

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

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