how to test psu and reset to cmos to default
hi,
x-posted this is not a very popular topic as i keep losing people :-) but i'd appreciate any help. ibm aptiva 2159-s90 (1997; split system; win95B) SUDDENLY for no reason, had post-start-up errors (date and time change (they hadn't changed) and config change -- referred to the floppy drive)) the floppy was fine (basically) i changed the battery last pm and it wouldn't pass the post (at all) cleared the cmos (paper btwn clip and battery overnight) it booted this am; many post-start-up errors (some phantom) currently: the cd-rom (in the media console) is running however the pc won't recognize the win95 cd (the cd-rom is set as the 4th start-up device) the post-start-up error now is: "adapter card resource error" which i think refers to the media console controller card (since it's in an isa slot) i have NO CLUE what to do about that. so i want to get the pc to reset to factory settings and don't know how to get this (it is not listed (although it used to be)) i need to test the psu and want to make sure that this is correct: i'd put the positive (red) probe (backprobe) to for example the red wire on the power cable to the hd and THEN ground it (for example using the p8-6 and p9-1(the center black wires on the power to the board adapter?)) any help is greatly hoped for and appreciated |

I haven't read stuff like this since English Comp 101 lol But...I'll try to help...with both! lol ibm aptiva 2159-s90 (1997; split system; What's a 'split system'? win95B) SUDDENLY for no reason, had post-start-up errors (date and time change (they hadn't changed) What do you mean 'they hadn't changed'? and config change -- referred to the floppy drive)) How many floppy drives do you have? What size are they? the floppy was fine (basically) What do you mean 'basically'? i changed the battery last pm and it wouldn't pass the post (at all) What do you mean 'wouldn't pass the post'? What EXACTLY happened? Any error messages? cleared the cmos (paper btwn clip and battery overnight) You clear the BIOS by use of a jumper...and then only momentarily. Go get a new batter from Radio Shack and put it in. It seems like the battery is the biggest part of your problem so far. it booted this am; You can say 'morning'. We're all adults. We can handle it! lol many post-start-up errors (some phantom) Geez. What the hell do you mean 'phantom'? I can SEE why a lot of folks have given up on you! lol Make a note of any errors...EXACT verbiage. Then let us know. currently: the cd-rom (in the media console) What is a 'media console'? is running What do you mean 'is running'? The cdrom WORKS? Or...you can see an icon? Or... however the pc won't recognize the win95 cd (the cd-rom is set as the 4th start-up device) Try another cd and see if the rom can read it. the post-start-up error now is: "adapter card resource error" which i think refers to the media console controller card (since it's in an isa slot) i have NO CLUE what to do about that. Most of your problems probably have come about because your EZBios has reset itself to the default settings. Get the new battery first...then we can try to solve some of the other problems. so i want to get the pc to reset to factory settings and don't know how to get this (it is not listed (although it used to be)) WHAT is not listed? What are you talking about here? i need to test the psu Not yet you don't. One step at a time. None of your problems so far sound like a Power Supply Unit (PSU) problem. and want to make sure that this is correct: i'd put the positive (red) probe (backprobe) to for example the red wire on the power cable to the hd and THEN ground it (for example using the p8-6 and p9-1(the center black wires on the power to the board adapter?)) any help is greatly hoped for and appreciated Depending on what you've really done, you may have even shorted out the hard drive also. Do this... Get the CMOS battery...put it in. Then disconnect the hard drive. Then boot the machine into the BIOS...and make sure all the settings are correct for your machine. Then power down...unplug...and plug in all drives. Record any error messages you may get...and get back to us. When the CMOS battery is getting low, you'll start to lose time on the computer (other things can cause this also, however). This is a good warning that you should replace the battery soon. So its a good idea NOT to run programs that'll automatically go out and reset the time on your computer. If you get several bad or incorrect boots, most EZBios will finally boot to default, safe settings. This may have happened in your situation. Get a good battery...then we can continue.

Since colors do not match what should be ATX power supply wires, I
suspect this is an AT type machine. Is this a 486 computer or an computer not using PCI cards? One voltage is wrong because I believe it should have read -5 volts and not +5 volts. The + 12 and -12 volts are both too low. Normally this would means doing the next step for excessive ripple voltage (which requires better equipment). However + and - 12 volts don't drive anything critical on AT type computers. This post will continue on an assumption it is an AT type computer - noting that if it is an ATX computer, then it might be a severely questionable - probably defective - power supply. But we assume it is AT. Anything that is IBM original checks out just fine with those diagnostics from IBM. Rarely do diagnostics get updated when they are working fine - Y2K not really considered important. But for added peripherals such as CD-rom or hard drive, then you must download the diagnostics from the manufacturer of that peripheral. A 30 gig drive in an older computer like this means the computer is probably using some type of Bios Extender - Ez-Bios or whatever that hard drive manufacturer provided. You must identify that Bios Extender and obtain operational details. For example, some require the BIOS to be set to a non-standard setting. If you did as so many others want - fix this and fix that rather than first collect facts - then it is possible you have lost what is the unique settings for that Bios Extender program (that is loaded on the hard drive). Generally Bios Extender programs would announce themselves when computer first booted normally. Software is often provided by hard drive manufacturer on manufacturer's web site. But at any rate, discover if and what that Bios Extender is. Normally your computer (check the manual) would only understand hard drives of maybe 8 Gig max. To see a 30 Gig drive, unique software such as a Bios Extender, or an ISA slot card that provides extended Bios, or a hard drive interface card with that Bios Extender must be somewhere in that machine. Diagnostics from hard drive manufacturer might help to identify that Bios Extender. Also what can provide useful information is to boot machine with DOS (if possible) and run the MS provided program called FDISK. Don't do anything that would fix or modify the drive. Just select the option that would read drive information ... to learn how that drive is setup. And yes, this assumes you can boot DOS. BTW, when we are all done, you want to record these unique setting on Post-It notes and mount those notes inside the machine. Now if I understand your original post - which I never really saw - you can boot from floppy but not from hard drive? I was never sure what did boot and how failed booting failed. Which OS does and does not boot how? If this is a Windows 95 machine, then it does not see the 30 Gig hard drive. Windows 95 is limited to hard drive of only 2 Gigs (if I remember correctly). So you can see how I find some of your information contradictary. At any rate, barring a missing negative sign and assuming this is an AT type machine, the power supply would be sufficient meaning we move on to other suspects. I am very suspicious of how that hard drive is configured and suspect a Bios Extender - which sometimes makes complexity. |

Is this a 486 computer or an computer not using PCI cards? it's a pentium 200 mhz mmx. it is NOT an ATX (it does not have the *normal AT* form factor (i can look it up) however the psu should behave like an AT psu) One voltage is wrong because I believe it should have read -5 volts and not +5 volts. i will retest it (i unhooked the zip drive (which is not working) and the slave hard drive just now and it only reached the ibm splash screen (counted video, cache and system ram -- accurately) then stopped (no POST no beep code and it won't even read the boot disk nor let me into the bios) The + 12 and -12 volts are both too low. Normally this would means doing the next step for excessive ripple voltage (which requires better equipment). However + and - 12 volts don't drive anything critical on AT type computers. actually what i have read is that the -12 volts is for isa devices and this pc has the media console controller card (which is isa) (the media console is a 3rd piece -- it has the cd-rom drive, the floppy drive and the power switch in it -- connects to the card (via a cable)) i'll redo the voltages i also found the service manual which has the correct ones (the colors are different from ats that i have seen) This post will continue on an assumption it is an AT type computer - noting that if it is an ATX computer, then it might be a severely questionable - probably defective - power supply. But we assume it is AT. Anything that is IBM original checks out just fine with those diagnostics from IBM. Rarely do diagnostics get updated when they are working fine - Y2K not really considered important. except that it only tests 32 MBs of ram and did not test the 30 gb maxtor drive but tested only 3.2 gbs of the slave (ibm) drive (which is 6.4 gbs) i'll try it on the off chance the pc will start gain But for added peripherals such as CD-rom or hard drive, then you must download the diagnostics from the manufacturer of that peripheral. the cd-rom, floppy drive, psu, cpu and 2 of the 4 simms are original. (the board was replaced supposidly in 1999) A 30 gig drive in an older computer like this means the computer is probably using some type of Bios Extender - Ez-Bios or whatever that hard drive manufacturer provided. You must identify that Bios Extender and obtain operational details. For example, some require the BIOS to be set to a non-standard setting. If you did as so many others want - fix this and fix that rather than first collect facts - then it is possible you have lost what is the unique settings for that Bios Extender program (that is loaded on the hard drive). i used max-blast (hard drive install utility (version 1.26s)) on the 30 gb maxtor (in 2000) -- there was nothing in the bios to change... it's on a floppy disk Generally Bios Extender programs would announce themselves when computer first booted normally. it always announced ezBIOS right after passing the POST. (but i had not see the ezBIOS text since i replaced the battery 2 days ago) this morning after changing the boot order ezBIOS appeared again. Software is often provided by hard drive manufacturer on manufacturer's web site. But at any rate, discover if and what that Bios Extender is. Normally your computer (check the manual) would only understand hard drives of maybe 8 Gig max. it only sees a bit over 8 gb (in the bios -- always) but windows sees all 30 gbs To see a 30 Gig drive, unique software such as a Bios Extender, or an ISA slot card that provides extended Bios, or a hard drive interface card with that Bios Extender must be somewhere in that machine. it is a diskette. Diagnostics from hard drive manufacturer might help to identify that Bios Extender. i don't know whether maxtor still exists... i was using a 3rd party diag on some baby ats but cannot recall what it was called but it was good Also what can provide useful information is to boot machine with DOS (if possible) and run the MS provided program called FDISK. i cannot do that right now... b/c of the above Don't do anything that would fix or modify the drive. Just select the option that would read drive information ... to learn how that drive is setup. And yes, this assumes you can boot DOS. BTW, when we are all done, you want to record these unique setting on Post-It notes and mount those notes inside the machine. i have them (aside from the pnp menu -- this is an ibm bios "ibm surepath setup utility" -- it is not like award or others) Now if I understand your original post - which I never really saw - you can boot from floppy but not from hard drive? now i can't but before removing the zip and slave i was able to boot to a floppy and then changed the start-up order (which had changed on its own to the following: 1st and 2nd floppy, 3rd disabled and 4th was listed as the cd/dvd rom.) i changed it to1st = floppy, 2nd = hd, 3rd = cd-rom) THEN it booted into windows.... I was never sure what did boot and how failed booting failed. Which OS does and does not boot how? currently none (i have windows95B installed) If this is a Windows 95 machine, then it does not see the 30 Gig hard drive. Windows 95 is limited to hard drive of only 2 Gigs (if I remember correctly). So you can see how I find some of your information contradictary. i am sorry for the vagueness... (i think it's 8 gbs but in windows it sees (saw) all 30 gbs... (the slave drive was always recognized as 6.4 gbs in the bios and in windows)) At any rate, barring a missing negative sign and assuming this is an AT type machine, the power supply would be sufficient meaning we move on to other suspects. I am very suspicious of how that hard drive is configured and suspect a Bios Extender - which sometimes makes complexity. i appreciate your reply VERY MUCH... i'm going to retest the psu (and compare to the tech manual) the master has a power connector which has the 4 wires going through it (i.e. is a pass through -- unlike connectors that end in the device) i don't know where to put the probe??? THANKS! sincerely Tanya |

snip
here are the corrected psu readings (from the manual) (the voltages in (...) are the specified ranges) (they are referred to as 1-12 although there are 2 separate connectors into the board) 1 = power good (5.00 v) 2 = 5.04 (3.75-6.25) 3 = 11.71 (9 - 15) 4 = - 11.87 (-9 to - 15) 5 , 6, 7 (grounds) but are -0.00 8 = (ground) 0.00 9 = -5.01 (-3.75 to - 6.25) 10, 11, 12 = 5.01 (3.75 to 6.25) the hd connector 1 = 11.71 (12 volts) 2 and 3 are grounds) 4 = 5 (5 volts) (both connectors were equal) i CANNOT test the power to the media console controller card... not even sure how to remove it -- (since it has the power switch, the a-drive and floppy drive) it is sort of square (however the manual has wire 1 as 5 volts and wire 4 as 12 volts) any suggestions? thanks sincerely Tanya |

The same is true of other hardware and ports. For instance, you can tell the computer that you don't have a printer port...by not enabling it in the CMOS. When you boot, you won't be able to print. i just want to be accurate: it was running well -- and without touching it, downloading things, changing h/w/ s/w etc (i.e. with NO provocation -- sorry:-) it began eliciting error messages (instead of the usual POST pass (1 beep) it gave 2, and the aforementioned errors on the screen)) Get back to us as to where you stand now...what problems you have. P.S. You DON'T have a PSU problem...so don't mess with it. good to know Good luck. Have a nice one... i really appreciate your help and patience! sincerely Tanya Trent© Budweiser: Helping ugly people have sex since 1876! |
