Lightbulb lose of booting when power fails


yesterday my son was thrashing around in the basement and we lost power in my puter room but then my Linux box started acting crazy, when the power was turned back on it tried to boot from the home network but that has not been set up yet. (did I mention that this unit was a used unit?)Now it will not boot at all. I replaced the battery on the board but to no avail.( had a low battery message on boot attempt.) Then it goes to the mac address and says a couple other short things and because it cannot find the required net address, it just sits there.Tried floppy. cd, hd- nothing.

Any Ideas?

Sounds like the CMOS settings were corrupted due to the battery being bad and the computer losing power. Make sure the BIOS configuration for the floppy is 1.44M and the hard drive is set to auto.

What is the make/model of the computer. Assuming that the network boot option is last in the list the BIOS can not find any other bootable device. Check the BIOS settings again.

Thank yui for the earlier answer but that did not help. Now I have put a new battery in it but the only thing coming up on the screen is the video info at the first of the boot sequence, then it stops. Makes me wonder if the chip got spiked. how would I check that to make sure?

Try opening the computer and unplugging all peripheral devices (i.e. add on cards, drives, etc.) and boot with only a keyboard and monitor attached. If it tries to boot (and doesn't find an operating system, obviously, since you unplugged everything) then the problem is with one of the periphers; plug them back in one at a time to isolate the problem. If, however, it does not complete POST (Power On Self Test -- basically what the BIOS does before trying to boot an operating system) then you've likely fried some critical piece of hardware, either on the motherboard or the CPU itself. In that case, hopefully it's just a bad RAM chip. Try reseating the memory and swapping it out if possible. Good luck!

Did as you suggested but the post did not continue, changed the mem chip, still to no avail. Put the chip back in the one I took i out of and it works just fine. By elimination, what is left? What check should i do now?

Could you restate this sentence? I can't understand what you are saying. "works just fine" sounds like things are OK, but then you ask what to do next. I'm confused.

You might try taking out your (new) CMOS battery, and leaving it out for an hour or so with they system totally powered down and unplugged from the wall outlet. This is to make sure all capacitors are drained of any residual power they may be supplying to the CMOS. This should reset your CMOS. Put the battery back in, plug the computer back in, and try booting again. If you had previously customized any CMOS settings you will have to do this again now.

p.s. - I hope you are using proper static protection while doing all of this. Messing around with the motherboard, pulling batteries and memory chips and such, ... you could static-zap things while you're trying to fix them. Making the situation significantly worse!

I see what you mean, sorry I did not catch that. It worked just fine in my other 'puter. Ok, will take your tips and let you know the results in a few hours.

Well, I took out the battery and disconnected the power all night. After reassembly, it booted but now the login has become screwed up, I cant get in although my login on this machine is the same as my other two machines. Can the login be bypassed somehow? or changed?

RR?
